L6U n i t1-1L i s t e n i n g事故和身体恢复Harry Beecham works for a hi-tech German company based in the Munich. Last month, he was in an automobile accident. He was on his way to attend an important meeting in New York City. He had just arrived on a flight from London and was taking a taxi into the city. The weather was terrible and the road was icy. He was in a hurry so he asked the taxi driver to get him into the city as soon as possible. The taxi driver agreed and sped up but just as they left the airport, the car was out of control. It spun around and skidded into(滑入) the path of an oncoming truck.Fortunately, the truck was going too fast, so nobody was killed. But the taxi was severely damaged and both passengers were injured. The taxi driver survived with only a few injured because he was wearing a seatbelt.The car accident wouldn’t have been happened had the weather been better.Had he put on his seatbelt, he might not have been injured so badly.Had the weather been better, the accident wouldn’t have been happened.The taxi airbag had also been deployed(使展开), absorbing much of the impact. However, Harry, who was in the back seat, having put on his seatbelt. As a result, he was severely injured, and had to be rushed to the hospital.Now, a month later, Harry still can’t remember much of what happened. When he first woke up in the hospital, it was several hours after the accident and he wasn’t sure where he was. The bad news was that he couldn’t move his legs. This was because his back had been broken in the accident. The doctor later told him that he might never regain the use of his legs. Some of his nerves in his spine(脊柱) and legs had been damaged but everything else was OK. Now, Harry is trying to figure out what to do. If he works hard and exercises every day, there will still a chance that he legs will recover on their own. There are also some new treatments that might help his nerve regenerate. Still, he should be prepared for the long recovery and possibility that he might never walk again. Without the use of his legs, he wouldn’t be able to continue working in the same way. it wouldn’t be possible to travel, so he would have to find another way to attend the meeting. Either that or he would have to look for another way to make a living. Harry has a good disability insurance, so mon ey won’t be problem for a while. But sooner or later, he wants to be able to earns a living again. Of course he isn’t planning to give up on his legs. If he works hard, he might still be able to regain the use and learn to walk again. Some of his nerves had been damaged but there was a chance that they were healed. The new drugs being developed might make it possible for the nerves to grow back. Still, he has to face the possibility that nothing will work. Whatever happens, Harry is determined to think posi tively. Even he can’t walk, he can still attend the meeting all over the world. With technology, he could be anywhere and there is much that he can still do. Luckily, he still has to use his arms and hands and his brain is still functioning. With the right attitude, he can find a way forward. There is no reason to despair in or feeling sorry for oneself. That kind of think won’t solve anything. He just hopes that his company or another will get him a chance to prove himself. He could still be a valuable asset for them, come or make.Spun around使…旋转( spin的过去式和过去分词)L6 Unit 1-1 Dialogue 衣着和礼仪Hey, what do you think? do you like it?No, it’s too short.

The boy grew tired(厌倦) and bored while watching the sheep, so he found ways to amuse himself, such as climbing trees or chasing sheep. One day he came up with what he thought was a brilliant idea. He climbed to the top of a tree and shouted toward the village: “wolf! Wolf! Help me please!”When the villagers heard his cries for help, they rushed up the hill to rescue him and chase(追捕) the wolf away. Of course, when they got there, there was no wolf to be seen, and the boy, who was still in the tree, was laughing. The sheep were grazing(吃草) peacefully. Annoyed. The villagers returned to the village and back to their normal activities.A few days later, the boy grew bored again and played the same trick on the villagers. This time the villagers were furious at the boy. That night he was punished by his mother for his bad behavior.For a while after that, life went on as normal and the boy behaved. He didn’t want to be punished again. Then, one afternoon while he was tending the sheep, he noticed that the sheep were bleating(小羊的叫声) and nervous. He didn’t know what was causing their strange behavior, so he climbed a treeto see if he could determine what was going on. What he saw from the tree was a frightening sight, a big, hairy wolf chasing after the sheep. Terrified, he screamed for help: “wolf, wolf! There’s a wolf chasing the sheep!”This time, when the villagers heard his cries for help, they were convinced that it was another one of his pranks(恶作剧). Nobody believed that there was really a wolf, so they ignored his frantic(发狂的、发疯的) calls for help. The wolf, having nothing to fear, feasted(大吃大喝) on several of the sheep and then slipped back into the forest.Feast on 尽情享受What would you do if you ever found yourself lost in the wild? To find out, you can join a weekend survival course in Australia’s Outback Desert(内陆沙漠). This vast area is famous for its harsh(残酷的、严厉的) desert climate.To survive, your first task will be to find water, a rare commodity in the desert. Animals such as ants and seed-eating birds are strong indicators of water. You can also cut and suck moisture from the roots and leaves of plants. Trees like the desert oak(橡树) have roots near the surface. But be careful. The branches of gum trees are a rich source of water, but the leaves are poisonou s, so don’t eat them. The best place to build a shelter is in an area with the least amount of(最少的) sunlight, like between sand dunes(沙丘) or trench(沟). To make a trench, dig a hole enough to lie down in and use the extra sand to create a barrier or wall on each side. This can help to shield you from the glare(刺眼) and scorching heat(炎热的) of the sun. nights can be cold, so knowing how to make a fire is essential. One way to build a fire is to use the hand drill(钻头) method. This is one of the oldest and simplest ways to start a fire. It involves rolling a stick between your hands while pressing it onto a notched(凹口的) piece of wood with dry tinder(引燃物) below. The idea is to use friction to create enough heat to ignite the tinder, this can be a lot of work.As fo r food, you’ll have to be open-minded. Some forms of life can be ugly to look at but can provide you with enough protein to survive. They may even taste good, like scrambled eggs(炒鸡蛋).Shieldn.盾;护罩;盾形奖牌;保护人vt.保护;掩护;庇护;给…加防护罩scorchvt.& vi.烧焦，烤焦vt.使（植物）枯萎，把…晒枯;使成焦土;痛骂vi.烤焦;<非正>高速行驶n.烧焦处，焦痕;枯萎，植物褐色斑点scramblevi.攀登，爬;争夺，抢夺;（植物）蔓延;[航]紧急起飞vt.攀登，爬;把…搅乱;炒（蛋）n.抢夺;混乱;攀登;[航]紧急起飞L6 Unit 1-2 Listening 过去时和虚拟语气Now that you have studied English at a high level, you need to be able to talk about the language itself. One of the biggest areas of confusion for students is the difference between the pass tense and present prefect. The pass tense is indicated by use of pass tense marker, represent V(d). here are some regular verbs and their pass tense forms. So, as you can see, for regular verbs, the pass tense form is indicated by the addition of “ed” at the end of the verbs. However, some of the common verbs in Englis h is irregular, so it’s important to learn them. Here are some examples. Altogether, there are over 200irregular verbs in normal use. Many people think that the pass tense form only indicates the pass time. However, there is only one of the possible meanings. The pass tense form is also used to express something that is unlikely or imaginary, from the speaker’s point of view.Here is an example,He wishes he had a car.The fact is that he doesn’t have a car, so the use of had indicates that it isn’t real, it’s imaginary.If he had a car, he could drive us to school. Again, he doesn’t have a car, so he can’t drive us to school. This condition expresses something that isn’t a fact. It’s a counterfactual condition, which means it goes against what we know or believe.Look at these two sentences,If she waits another week, she can save money.If she waited another week, she could save money there is going to be a sale.both sentences are correct, but they have different meanings. In the top sentence, the condition that she waits is more likely from the speaker’s point of view. In the bottom sentence, the speaker thinks that it’s less likely that she’s going to wait.If that flight leaves on time, we are going to miss it, so let’s run.If the flight left a few minutes later, we could take the next shuttle bus.When we talk about the experience of result, we use the present perfect form. This form uses have followed by the participle. for regular verbs, this participle(分词) is identical to the pass tense form. For irregular verb, this participle is different. When we use the perfect form, the primary focus on the subject of the sentences, not the verbs. It emphasizes its condition, experience of results, rather than action or event. In these 2 examples, we see the contrast.She has already left the hotel.She left the hotel a few minutes ago.The top sentence gives the condition or state of subject, and the bottom sentence expresses the event. The top sentence describes the condition of the subject of the sentence, she rather than the event. The fact she has left the hotel is now part of her experience or state of being. The bottom sentence expresses the action or event, she left, which is something she did. In general, the pass tense expresses the event or acts, and the perfect form expresses the experience or conditions. When we use the perfect form of the verbs, we focus on the state of the subject and not the action or event.Know that the pass form expresses events of specific point or periods of time, such as late year or the pass 5 years.These events distance from the speaker’s point of view.He worked at several companies. He finished the project last week.The perfect form expresses the state of something from the speaker’s po int of view, not distance in time. He has worked at several companies. He has finished the project.These 2 sentences are incorrect and confusing they give 2 different points of view.He has finished his work last week.Here are some sentences that use the perfect form. Some are simple, such as the first one and some are complex, like the last one.He has finished practicingHe has been practicingShe may have been practicingShe may have eatenHer computer may have been stolenThe last one is complex because it combines many verb forms, including the passive.L6 Unit 1-2 Dialogue 都市迷失What are you thinking about, you look so panic?I was just thinking about how much things have changed since I was a child.Oh, sometime I have think about that too. What were your thoughts?The nostalgic(怀旧的) for sure. Generally, I remember the best times and then I get a bit depressed when I’m thinking about how things have changed.What kind of changes depress you?Well, one thing i s the pace of life. Everything is so fast personnel, so there isn’t enough time to think. That’s because you’ve grown up. You’re not a child anymore so you have responsibilities.It’s more than just having responsibilities. My parents had to work but they also had other things. My father used to go fishing on the weekend and mon used to work in her garden. She loved to grow flowers and vegetables.Yeah, that does sound nice. Living in the city makes thing like that, really difficult.Yes, living in the city is certainly a part of problem, right.Well, that depends on you. You make thing sound as if you have no choices in life. It’s the choices you’ve made that push where you are now.Sure, that’s certainly a part of problem. I guess I’ve changed.You want a lifestyle that you can’t have in the city. If you really wanted those things, you can move back to the countryside.Not, that’s not an option. If I did that, my wife would d ivorce me.Have you ever talked about it with her?Not, I haven’t. you don’t talk about things like that. You are both too busy. I think she’s even busier than I am.Well, maybe she will surprise you. Maybe she’d like a change too. You should talk to her.Em, I don’t know. What about you?I’m okay. My wife and I accept things as they are. They try to think positively and we support each other.It sounds like you have a good marriage.Yes, we do. And one reason for is that we share our thoughts with eac h other. We don’t want to grow apart like so many couples.Maybe I’ll surprise my wife and start sharing my thoughts with her.Well, if you don’t do it now, nothing is going to change.Yes, you’re probably right. I’ll think about it.L6 Unit 1-2 reading 南极洲和切尔诺贝利事故On Antarctica, the world’s coldest continent, the average high temperature is -49 degrees Celsius. In the summer, the sun never sets, and in the winter, it never rises. Keep sane(保持清醒) there is its own special challenge.The McMurdo Station is a research base perched(停留) on the edge of the Ross Ice Shelf, the world’s largest body of floating ice. The station is administered by the United States and is the largest community in Antarctica. Capable of supporting more than 1200 residents, the population of the station drops to 150 brave (perhaps foolish) people when winter begins in March. Their task is to maintain the station during the months of total night. The biologists, astronomers(天文学家),geologists, and climate scientists who were there before, have gone, as any research is impossible in the brutal(残酷的) winter.Every day the remaining stuff of maintenance personnel(维修人员) perform their routine(常规;例行程序)task and make repairs when needed. Sometimes they peer(凝视) through the darkness toward their friends from New Zealand, at Scott Base, about 2 miles away. Though most of the time they’re just voices on the radio, it’s nice to have neighbors not too far away. Together, they share a powergrid(电网) and one coast of a dark forbidding(令人生畏的) continent.Though the days are dark and freezing cold in the depths of winter, the moon will rest(休息) above the horizon(地平线上) for weeks at a time. Its pale(苍白的、无力的) light illuminates the cold, craggy(陡峭的，嶙峋) landscape as if acknowledging a companion and reaffirming the bonds of life. So even for those who live in the darkest part of the earth, there is light.To acknowledge somethings means to recognize or admit its existence.The writer shares what it feels like to live and work in Antarctica.On April 26, 1986, Unit 4 of the Chernobyl nuclear reactor in northern Ukraine, then a part of the Soviet Union(苏联), was shut down(停工) for an unauthorized safety test. When the nuclear fuelrods(杆) hit the cooling water, the fission reaction(裂变反应) accelerated out of control due to a sudden power surge(动力高峰）. This caused the reactor to overheat and build up pressure until its structure failed and it blew up(爆炸), releasing large amounts of radiation. It took officials a whole day to comprehend(理解) the scale of the disaster and to order an evacuation(疏散) of the surrounding area. Some 50,000 people had to leave, not knowing that they would never return.In the following months, massive efforts were made to decontaminate(净化) the area while increased radiation levels were detected across much of Europe. Fallout from the disaster continues to this day, decades later, and long-term effects such as cancers are still being investigated. Estimates of the number of deaths that will eventually result from the accident vary enormously.The forest area near the reactor site is one of the most radioactive places on Earth. Named the Red Forest because its trees turned a reddish-brown(红褐色) color as they died, the forest is trying to make a recovery. Animals such as elk(麋鹿) and eagles(老鹰) have been seen in the area. And birch trees(桦树) grown where the radioactive trees of the forest were bulldozed(铲平) and buried by the Soviet government.Some people have returned as well, mostly former residents who returned illegally after the evacuation. The old company town of Pripyat, once home to 50.000 plant workers is still deserted, but is slowly being reclaimed(再生) by the forest. It seems that nature can recover and even thrive where humans cannot. Let’s hope that humans can learn from this experience. Chernobyl, and more recently, Fukushima in Japan, have lessons to teach us.It’s clear that the officials were completely unprepared for the accident.L6 Unit 1-3 listening 神经疾病和身体恢复Jack is a psychiatrist, which means he treats people who have mental problems. He has been treating patients for many years and he has used variety of treatments. Sometimes he just listens and talks to patients and sometimes he uses meditations. This meditation affects the brain in many different ways. Over the years, Jack found that some patients improved with the treatment while others did improve at all. In some cases, some patients respond to the treatment was the opposite of what was expected. Several years ago, he had a young patient who showed him why his treatment didn’t work. The patient’s name was Bob. He was 21 years when he first came to see Jack for help. The reason he came was because he had attempted to suicide.Bob was extremely smart and was a student at one of best universities in the world. However, he was often extremely depressed. Because of his depression, he took drugs and drank a lot of alcohol. It was an overdose of drugs and alcohols that nearly killed him. His roommate called 911 when he discovered Bob unconscious in dormitory room. Once Bob recovered and was discharged from the hospital(出院), he took time off from school to get help. That was when he came the clinic where Jack pack his medicine. At first, Jack attempted to treat Bob with anti-present medicine. He also used conversation and recommendations to help him to rethink his life and memories.After a few months, Bob began to improve but only moderately. Though he cooperated with the treatment, he continued to think negatively. He also continued to go through periods of depression. As a result, he wasn’t able to return to school.Because of the treatment was working, Jack tried something new. He decided to use brain scans to see inside Bob’s brain. Brain scans is a way to look inside the brain to see how it was functioning. What the scans showed about Bob was crucial. They showed that his brain was damaged in a way that nobody had anticipated it. there was significant damage to the front part of his brain. an injury to this part of brain can contribute to depression and negative feeling. It can also contribute to feeling of anger and rage. The fact his brain was injured and unbalanced expresses why the treatment hadn’t worked.The brain scan showed why the meditation and other treatments had worked. They had failed because they didn’t address injury. After discussing the injury with Bob and his parents, they concluded that the cause of the injury was from playing soccer. In fact, Jack knew of quite a few soccer players who had suffered head injuries from playing that sports. Heading a hard soccer ball many times can damage the brain.With this new information, Jack used a new medication to treat the injury. Gradually, Bob improved, and after a few months, was close to a full recovery. He no longer had any signs of depression and was finally able to return to school. Ultimately, Bob graduated from his university with great honors and entered a famous law school. From this experience, Jack realize that the brain imaging had allowed him to save Bob’s life. If it hadn’t been for the scans, Bob would have ended up killing himself.Detecting and treating the injury to the front part of his brain was the key step in the treatment. Jack now believes that the brain scan can be an important tool for psychiatrists. an injury brain must be healed before other treatments such as vitamins, drugs or counselling, can work.He wouldn’t have to come to see Jack if he hadn’t tried to kill hi mself.He hadn’t attempted suicide; he wouldn’t have come to see Jack.Had the treatment been successful, he probably would have returned to school.L6 Unit 1-3 Dialogue 健康类电子产品We’re getting a lot of complaints.About the proposed new policy?Yes, people think that it’s an invasion of policy.Don’t they agree that regular exercise and staying in shape is good for anyone?Sure, they agree. But we don’t think we have the right to use an APP to track how much they exercise. Using the app is the only way to make sure our employees to get enough exercise.This new policy can reduce our health cost and increase productivity, which helps everyone.That’s not how they see it. This kind of regulation makes people feel like robots. They have no freedom anymore. Requiring anyone to wear a smart device like this on their waist means they don’t have no privacy.Well, if you put it that way, i can see the problem.However, i don’t see any other way to change people’s habits. This is just a friendly minder.It’s more than a reminder. It makes things public and puts pressure on people to meet their requirements. It will force people to work out even if they don’t want to. They won’t be any choice. No, it hasn’t had to be that way. We can still be flexible.That’s not the point. People hate the idea that the company knows everything they do. It’s bad enough that they had to communicate with each other at night and on weekends.What if we made the use of the APP an option?If we do that, it still puts pressure on people to use it. I think it’s best that we get rid of this idea. I’m all forward standers but what about freedom and creativity. If we go ahead with this policy, I think we will lose some of our best people. There are other ways to deal with health issues.Such as… What’s your suggestion?Give extra holidays to people who take fewer sick dates.No, that wouldn’t work. It will put pressure on people to come to work sick and get everyone else sick too. If someone is sick, I’d rather that they stay at home.Then here is run out of idea. Why let your department manager handle it? They are the one who decide on promotions of bonuses. Setting everything in stone in the form of policies can be very dangerous. (以政策面前设置无法改变的一切是很危险的)Ok. I’ll consider it. But now I’ll give up the idea of using this APP. Please let people know that we are listing to them. We do care about our employees.I’ll. I’m sure than people will appreciate it. It shows that you have faith in them.Thanks, i appreciate your advice.They think it gives the company too much control over their lives.He would rather have sick people at home than come to work.L6 Unit 1-3 reading 伤病预防、高血压和心脏病Preventing injuryExercise and a certain amount of strenuous(紧张的) physical activity are important for maintaining good health. However, before engaging in them, it’s important to know how to prevent injuries from occurring, especially for athletes and elderly people. Injuries can be minimized by doing a proper warm up. This consists of increasing your heart rate and blood flow to all part of your body. A good way to do this is through a series of static stretches(静态拉伸) followed by a series of dynamic stretches, which are done while moving.Using the proper equipment is essential, especially in contact sports. To protect the head, for example, well designed helmets can greatly reduce the incidence of concussions(脑震荡). Concussions are caused when the soft, jello-like(果冻状) brain slams into(用力撞上) the hard human skull(颅骨). Research shows that repeated concussions can have serious consequence.Compression sportswear (紧身服)is another way to reduce the risk of injury, especially muscle injuries. More and more athletes are using them because their use can also speed up muscle recovery when an injury occurs.Another contributing factor in sports injuries is fatigue(疲劳). Doctors believe that fatigue is an important warning sign that the body has reached its limits. When fatigued it is more difficult for thebody to protect itself. Therefore, it’s a good idea to stop an activity at the first sign of fatigue. Rest periods, even for professional athletes, can prevent serious injuries from occurring.Understanding injuries and the body reaction to them can help people cope with the problems that accompany physical exercise. The support and understanding of coaches, teammates and family can be a critical factor in prevention and recovery. Once an injury occurs, it’s too late to prevent it, and recovery can take a long time. For the elderly, a simple fall can be fatal(致命的).Compression n.压缩A fatal accident or injury is one that causes death.Blood pressure and stoke.A large international study has found that then risk factors account for 90% of all the risk of stroke. Of that list, 5 risk factors usually related to lifestyle are responsible for a full 80% of stroke risk. According to the researchers these risk factors- high blood pressure, smoking , abdominal(腹部的) obesity, diet and physical activity - are modifiable and can be controlled.The findings come from a study of 3000 people who had had strokes and an equal number of healthy individuals with no history of stroke. This study also includes a brain scan of all participating stroke survivors, according to the researchers.Across the board(全部), high blood pressure was the most important fact, accounting for one-third of all stroke risk. Blood pressure, it was noted, plays a major role in both forms of stroke: ischemic, the most common form(caused by blockage of a brain blood vessel), and hemorrhagic(出血性) or bleeding stroke(中风), in which a blood vessel in the brain bursts(爆发).Blood pressure is easily measured, and there are lost of treatments. Lifestyle modifications to control it include increasing physical activity and reducing salt intake. The other lifestyle risk factors are modifiable as well. High intake of fish and fruits, for example, is associated with a lower risk of stroke. Many of the same risk factors have been reported in other studies, but this is the first stroke risk study to include both low- and middle-income participants in developing countries. The study confirms that high blood pressure is the leading cause of stroke in both developing and developed countries. This highlights the need for health authorities in those countries to develop strategies to reduce high blood pressure, salt intake and other risk factors.The other lifestyle risk factors are modifiable as well.According to this articles, lifestyle factors are responsible for most stroke.Study confirms that high blood pressure is the leading cause of the stroke.L6 Unit 1-4 listening 买房、换工作John and Linda are worried about their future. They both have good jobs but they are concerned about their economy. Of the 2 of them, Linda is the most worried. She wants the security of owning her own home. Her husband disagrees. As a result, they often fight about money. They live in a nice apartment, but their rent goes up every year. So now they are trying to decide whether or not to buy a house. Linda wants to buy a house but John is against the idea. He thinks prices are too high and he doesn’t want to be trapped. If they owned a house, it would be more difficult for them to move somewhere else if things changed. For example, what would happen if he lost his job. If he lost his job, they might want to move to another city or country. If they own a home or flat, it would more difficult to move. If they decided to move, they would probably have to sell. If prices have risen, that would be OK. In fact, they might even make a profit. However, if prices were down when they have to sale, they would lose money.。

It is a beautiful, rotating sphere. The side facing the sun is in daylight. The side facing away from the sun is in darkness. For example, when it’s daytime in US, it nighttime in China. In fact, there’s 12-hour time difference between Boston and Shanghai. When it’s midnight in Shanghai, it’s noon in Boston. The earth rotates from west to ea st.

When it’s 10 am in New York, it’s 7 am in San Francisco. Europe and the US are separated by several time zones. When it’s 5 pm in Paris, it’s 11 am in Boston.

L4 Unit 2-1Listening物种、环境The earth was born about 4.6 million years ago. The first life appeared about a billion years later. The first plant didn’t appear until around 2 billion years ago. Until around 580 million years ago, life formedweresmall and microscopic (微笑的). Since that time, lives has evolved to many different types and species. However, scientists estimate that more than 99% of them are now extinct.They have been several extinction events in the history of the earth. In the extinction event, many life forms or species of life die out. The causes of the massive extinction events are unsoughtmystery. These events are not predictable and can happen at any time. Scientists think that some of that started by asteroid pass or volcano corruption. Events like this, can change the global conditions that life depends on.One major extinction event, happened about 66 million years ago. That event may have been started by a large asteroid that hit the earth. As a result, the dinosaurs and about half of the all species on the planet, died out. When the asteroid hit the earth, it started a chain of events. A chain of event is a series of events linked together, like a chain.These particular chain of events happened over a period of months and years. When the asteroid hit the earth, it caused huge cloud of dust to enter the atmosphere. This cloud of dust blocked the sun and darken the earth for a period of months. Without enoughsunlight, plants and plant-eating animals, quickly died. With the deaths of so many plants and animals, the food chain collapsed . This led to the deaths of many more species.Mass extinction events had played important part in the evolution of life. In fact, some extinction events had helped to accelerate evolution. For example, somem ammals lived to the age of dinosaurs, but they couldn’t compete. When the dinosaurs were removed, the mammals were able to compete more successfully. Once they could compete, mammal evolved to a higher state. Without the extinction event, perhaps we wouldn’t be here today.Scientist estimate that there have been at least 5 massive extinctions in the pass 540 million years. They also believed that we had entered a new extinction event. Species are becoming extinct at a much faster rate than before. Instead of the asteroid and volcano corruptions, the current event is the result of human activities. Human activities, for example, had led to global warming.Global warming is the result of an increase in carbon gases in our atmosphere. These gases trap heat from the sun, so the earth is getting warmer. As a result, sea levels are rising and weather patterns are changing. In addition, we humans are destroying habitats of many plants and animals. Cutting down forest and polluting rivers destroys the habitats of many forms of life.There is no longer any doubt that this is happening. Specials of lives are disappearing at an increasing rate. Global temperatures are rising and weather patterns are changing. Scientists are warning us that fast action is necessary to save our future. If we don’t act, we may go the way of the dinosaurs.L4 Unit 2-1 vocabulary身体系统、产业、技术The body circulatory system includes the heart and blood vessels.

It’s going to be one or the other. It can’t be anything else.Now let’s look at it from the man’s point of view. From his point of view, the probability is different. From his point of view, the possibility that he has an orange is 100% or 0%. That’s because he kn ows what he has. For hi m, that is not uncertainty. If he has an orange, the probability is 100%. If he doesn’t have an orange, the probability is 0%. He either has it or he doesn’t.From our point of view, the probability that he has an orange is 50%. From his point of view, the probability that he has an orange is 100% or 0%. So the probability depends on the point of view.People see things from different points of view.

U n i t2-1l i s t e n i n g退休和投资Walter wants to retire within the next few years. He has been working at the same company for over 15 years as an accountant. During that time, he’s been saving his money and paying off that debt. However, even with his savings and investments, he isn’t sure that he will have enough money for retirement. If it doesn’t, he will have to keep on working, which depends on the company. For now, the company is ok. But it’s no longer growing as fast as it used to. Whether or not he can keep on his working will also depend on his health. Fortunately, he is in good health. But he knows that that could change in any time. If he fell down or had a stroke, it could force him to stop working. If that happened, he would have to rely on his savings and other assets to survive. Soon or later, he knows his health will decline and he will have to stop working. So he needs to prepare.Most of his wealth is in the form of company stock and the value of his home. Both of these are at risk. The company stock may go down and the value of his home may also fall. The company he works for is a pharmaceutical(制药的) company. It develops new drugs which is risky business and sells them worldwide. It’s expensive to develop new drug s and it can take a very long time to get a new drug approved. Without government approval, it can’t be sold, which can result in a huge loss. Another threat the company comes from foreign competition, which is getting stronger. The company has also started to move some of its researches and production facilities oversees. Salary level is lower there, and the quality of the foreign workers is getting better. As a result, the company has to reduce its local hiring and it’s no longer giving large bonuses.One thing he is considering, is to sell his share in the company. He could begin to sell a little at a time and reinvest the money in somewhere else. But where would he invest He doesn’t know much about investing and several of his friend have lost a lot by making a bad investment. Investing in real restate orthe stock market could be very risky. In the best case, he will make a lot of money. If that happened, he could finally retire and enjoy a comfortable life. On the other hand, in the worst case, his investments could result in a huge loss. If that happened, he wouldn’t be able to enjoy his retirement. He wouldn’t be able to travel or do any of things that he’s dreamed about doing. So now he has to decide what he should do. Should he begin to sell his stock in the company or should he wait until he actually needs the money. If he sold now, he will have to decide what to do with the money. His investment could turn out well or it could turn out to be a disaster. On the other hand, if you decide to wait, anything will depend on his company. The one advantage he has with this options is he’s being on the inside of the company. With his insider information, he can predict the company’s shot-term future. This is especially true because as an account, he has an access to the company’s financial data. If things start to go badly, he can begin to sell his stock and avoid a big loss. Otherwise, it’s probably safer to keep the stock and hope that t he company does well even if its growth rate declines. So for now, that is probably what he should do. If you were he, what would you doUnit 2-1 dialogue 非洲和巴黎旅行So, where should we go on our vacation. What about AfricaAfrica, no, that’s not for me. Why do you want to go the AfricaI’d like to get out and see the wildlife, the drama of nature! We could see some of the great migrations. Wow, you are adventurer. What about food and diseases What about terrorism.Sure something that could happen. But if we never take any risks, we won’t have an interesting life. I don’t want to have a boring life.So, you think I’m boring then, right.Well, you’re certainly not the most exciting person. What plays thing safe and secure.I don’t mind take a few risks but it’s got to be worth it. Watching animals migrate is something I could see in a documentary. And I don’t like the idea of being around predators(肉食动物), like lions and hyenas(鬣狗).Ok, my brave man. What would you like to doWell, I’ve been thinking about it. I think it’s nice to go to Paris in the fall and visit some museums. We can go to a concert and go to see a ballet.Ah, we’ve been to Paris before. That’s exciting about it and I’m tired of museums. Any other ideasOne place that might be interesting is in South America, Machu Picchu. It’s an abandoned city way up in the mountain Peru.Yes, I’ve heard of it. that might be interesting.Should we look into itSure, you look into it and I’ll get some information about trips to Africa.So your heart is ready set on Africa, isn’t itYes, it really is.

Maybe one of these days I will surprise you.Unit 2-1 reading 在线相亲和运动受伤Is online dating killing loveA fair maiden is guarded by a dragon. A handsome prince must slay(杀) the dragon to save her. Then, magically, they fall in love and live happily ever after.Traditional stories tend to emphasize the fantastic, magical side of love. Fate plays matchmaker(媒人). Strangers see each other from across a room and instantly know that they are destined to be together. It isn’t difficult to imagine two strangers coming together and falling in love despite their differences. It suggests that love is challenging, uncertain and incomprehensible.But with more people using online dating services, a very different kind of love has emerged: one that is scientific, convenient, and self-directed. It minimizes risk and provides a choice, like on a menu. There is anonymity and avoidance(逃避) of immediate rejection. Meeting terms are negotiated online.Online dating also allows the setting of preconditions. Computer algorithms(程序) exclude undesirable traits(个性/特征) such as the wrong hair color, race or age. But they also exclude randomness. They reduce the chances of meeting someone different, or someone who could challenge one’s romantic ideals. Instead, they find the partner we think we want and exclude everyone else. As a result, we could be missing the opportunity of a lifetime, to meet someone we would never have expected to fall in love with.Perhaps this new way represents a more efficient form of romance. Traditional ideas of love may be enchanting(迷人的) – but are they useful Loneliness and boredom are less exciting than chance encounters, but they represent the more realistic side of love. All too often people have suffered through had dates and humiliations(羞辱).If they could just choose what they wanted. Wouldn’t it save time and reduce suffering However, by choosing partners based on our preconceived ideas, we may be indulging in our illusions. Instead of letting ourselves grow with someone, love becomes more about looking for ourselves in the other. What if we don’t know ourselves as well as we think Perhaps love isn’t about knowing what we want. Perhaps it’s about being open to unimagined possibilities.Sport injuriesSport injuries are injuries that happen to athletes participating in sporting events. In many cases, these types of injuries are due to overuse of a part o f the body. For example, runner’s knee is a painful condition associated with running, while tennis elbow is a form of repetitive stress injury at the elbow. Other types of injuries, such as a broken bone, can be caused by hard contact with something. Injuries are a common occurrence in professional sports, and most teams have a staff of trainers and close connections to the medical community. Controversy has arisen at times when teams have made decisions that could threaten a player’s long-term health for short-team gain.Sport injuries can be classified as either traumatic(外伤的) or overuse injuries. Traumatic injuries account for most injuries in contact sports such as soccer, rugby(英式橄榄球), and American football. This is of course due to the dynamic and high collision nature of these games. These injuries range from bruises and muscle strains to fractures and head injuries.A bruise is damage to small blood vessels which causes bleeding within the tissues. A muscle strain is a small tear of muscle fibers and a ligament sprain(韧带拉伤) is a small tear of ligament tissue. The body’s response to these injuries is the same in the initial five-day period immediately following the incident –inflammation(发炎). Inflammation is characterized by pain, localized swelling, heat, redness and a loss of function.Inflammation is the first phase of healing, and typically lasts for around five days. However, too much of an inflammatory response can mean that the healing process will take longer, and a return to activity is delayed. Sports injury treatments are intended to minimize the inflammatory phase of an injury so that the overall healing process is accelerated.Runner’s knee is a painful injury that’s due to overuse.Inflammation is the first phase of healing and typically lasts for around 5 days.Unit 2-2 listening 情态动词Now that you have studied in English at a hi gh lever, let’s get a better understanding of the models. By now, you should already have a good understanding of what they meant. There are the models which are used to express the degree of certainty.Will shall may canThese models are used to make predictions, judgements and speculations. They indicate how much a speaker knows about the likelihood of an event.First, the model will express certainty as in if you heat water, it will boil. Based on what is known, the speaker is certain it would happen.The model may express possibility, as in it may rain this evening, but I’m not sure. Based on what is known, the speaker asserts that event is possible rather than certain or impossible.The model can express the potentiality or ability, as in he can afford it, but he may decide not to buy. The model “shall” is a bit different from others. Tina shall be there means the speaker is determined that Tina will be there. In other words, the speaker is determined to get her to come and would try to influence events to make it happen. We would never say it shall rain. Nobody can make it rain so whether it rain or not is beyond one’s control. If some were to say that, it would seem as they were claiming the power to control or influence nature. Know that the question shall I open the door invites the person who is asked to make a decision. Whether or not the door is open depends on the person’s answer. In contrast, will I open the door ask for a prediction rather a decision.Know what these models can be weakened or removed or by some of these pass time form.Would should might couldWe would go if we had more money but we don’t. this sentence expresses the speaker’s certainty of going if they had more money, which they don’t. so the certain prediction exists but in an imaginary or unreal situation. The model might express less possibility than may so might go is less likely than may go.The models could express less potentiality than can and it’s often used in conditionals(从句). If he could come expresses less potential than if he can come. If he could come, we would all be happier expresses the feeling that in fact he can’t come.Here are the second sets of model.Must, should, had, better oughtThese models express degree of logical force or social expectations. Know that none of them has a past time or weakened form.The first one must indicates logical or social necessity. It expresses the strongest logical or social force. The model should and ought to assert that something is probably or expected but not necessary.The model had better expresses advice or ability. In other words, if someone had better do something, they should do it or there may be negative consequences. Therefore, had better has a feeling of threat, as in you had better be there. This isn’t the same as you should do it, which means you are expected to do it but without an applied threat if you don’t.One interesting rule is that no more than one model can be used with any verb. There are no exceptions to this rule. Therefore, it’s incorrect to say “he will must be there”. To avoid breaking this rule, there are other words that have the same meaning but are not models. The case of must, for example, we use have to, as in we will have to be there. Similarly, we cannot say he may can come. Instead, we say he may be able to come.One last thing to know about models. We use the same form regardless of what the subject is. If the subject is I, it, we or they, we use the same form will. We would never say “we wills be there”. But with non-model form, such as have to, we must change the form to match the subject. He has to be there and I have to be there.We shall overcome all obstacles express determination to make it happen.We don’t know for sure but there is still a possibility that they can leave on Friday.Unit 2-2 dialogue 感情和分手What’s wrong You look awful.My boyfriend and I had just had another fight. I think I’m going to break up with him.Hey, you’ve said that before. Calm down. Is that really what you want to doYeah, I think so.

He can be very jealous and he has a violent temper.Anyway, what was your fight aboutIt’s just the way he talked to me. He never shows any interested in what I’m doing or in what I’m feeling. if I had a bad headache or anything he says nothing.So who started the fightHe came over and wanted to kiss me and I turned away. I told him I didn’t feel anything for him right then. So then he got angry and we both blew up. Now we are not talking to each other.Oh is that all That kind of thing is normal. Maybe you’re overreacting.No, it’s just that I’m beginning to realize that I don’t feel anything for him anymore.Our relationship is getting cold. We don’t feel appreciated.Well then maybe you should break up for a while and start seeing other men. But be careful. If I were you, I wouldn’t start seeing anyone else until I break up first.What do you think soIf he sees that you’re serious about breaking up, he may change.Maybe, but I doubt it.It could be that he feels the same way about you. Maybe he has lost interest. So it’s best to find out. You need to have a serious conversation with him.You’re right. Maybe it’s time to really find out.Unit 2-2 reading 爱情和旅游胜地马丘比丘The love labHow we communicate with our romantic partners can have a strong impact on the quality of our relationships. Psychologists John and Julie Gottman run the “Love Lab”, where thousands of couples have been studied over the last 30 years. The purpose of their research is to determine the factors that lead to happy and unhappy relationships. From their data, they have concluded that contempt(轻蔑), criticism, defensiveness, and stonewalling are the most significant factors that can hurt a marriage or relationship.Among these, contempt is the biggest predictor of divorce. People who feel contempt for their partner often convey disapproval without addressing the issue. They sometimes label their partner with insulting words such as “lazy”, “stupid” or “emotional” which is particularly damaging.Many couples try to address issues by criticizing their partner’s flaws or mistakes directly. Being too direct with criticism can hurt your p artner’s self-esteem. Some people may react to criticism by stonewalling, where they refuse to acknowledge and respond to their partner for a period of time. Unfortunately, fighting back or ignoring your partner can make it difficult to determine the root of your problems. If yourpartner feels that they aren’t valued, it may lead to increased dissatisfaction with the relationship. The Gottmans maintain that being aware of these factors in communication is the first step to improving a relationship. It is i mportant to acknowledge that all relationships have issues. The goal shouldn’t be to avoid these issues, but to learn to resolve them. In particular, we should avoid communication in ways that hurt our partner’s self-esteem. It is better to discuss problems in a way that is less confrontational and can better help your partner sympathize with your perspective. For example, rather than saying why are you ignoring me. It’s rude! One could say I feel hurt and undervalued when I don’t get a response from you. By being conscious of how we communicate with our partner, we can begin to build a healthier relationship.Their research has given us insight into how to make our relationships better.The lost city of the IncasMachu Picchu is one of the world’s most im pressive historical sites. It was built around 1450 by the Incas, who ruled most of south America at that time. They called themselves children of the Sun, the powerful god they worshipped as the source of light and life. Located in the Andes Mountains of Peru, at 8000 feet above sea level, the “City of the Incas” was mysteriously abandoned just 100 years after its construction. This was when the Spanish were beginning their conquest of the Inca Empire, in the 1530’s. there is no evidence that the Spanish invaders ever attacked or even reached the mountaintop city, so many believe that the city’s inhabitants deserted(抛弃) the site because of a small pow epidemic.The city was almost forgotten until 1911 when it was discovered by an American historian, Hiram Bingham, after he heard rumors of its existence. Bingham was led to the site by local farmers and was amazed by what he saw, which seemed like an unbelievable dream. He wondered if anyone would believe what he had found.Though the surrounding jungle had overgrown the site, what remained was impressive. The city had been built on a remote and nearly inaccessible mountaintop, often shrouded in clouds. Forty rows of farming terraces(梯田) hued the steep mountainside, each over 10 feet high and liked together by over 3000 stone steps. Among the city were what appeared to be neighborhoods of homes and exquisite(精致的) stone buildings that are thought to be temples. Even today, the mystery remains as to the purpose of these temples, how the city was used and what its citizens did.Despite its remote location, Machu Picchu has become one of the most popular tourist destinations in the world. Every year, thousands of people travel to Peru to admire its magnificent stonework and breathtaking design. What they see is a wonderful harmony between the city and the landscape around it that is captivating.Unit 2-3 listening 凯撒和肯尼迪之死In this course we have tried to prepare you to understand and discuss important topics that are often in the news. Sometimes the news is good news, but all too often we learn of problems and crises. Once in a while, an event is extraordinary and will change the word. In this lesson, we focus on 2 events that changed history forever.One of the most famous assassinations in history was the assassination of Julius Caesar. At the time of his death in 44 DC, he was the leader of Roman empire. His title was Dictator for life, which meant he had absolute authority for as long as he lived. He had gain this power through his successes as a military commander. In fact, historian considered him to be one of greatest military commanders in history. Once gaining in power and fought against the corruption and began to restructure the government. For example, he increased the number of senator and changed how they were chosen. Instead of being elected, they could be appointed, even if they are not from Rome. This action reduced the power of individual senators and shifted it to Caesar himself. In doing so, he created several of enemies, especiallythe aristocracy. However, he also had many admirers, who supported his efforts to end the corruptions. Caesar was s to death by a group of Roman senators, at March 15, 44 BC. He was scheduled to lead Rome, 3 years later, to fight in another war. He had appointed members of his enemies to rule the empire while he was away. This action angered many of Roman senators, who didn’t want to take orders from Caesar’s subordinates. He should have been aware that many of the senators hated him, but he dismissed the security force not long before his assassination. If he hadn’t dismissed it, the assassination attempt might not have succeed. On the day of his assassination, it is reported that Caesar may have been handed a warning notes as he entered in senate. If he did receive such a note, he didn’t read it. it seems that he was at the state of denials and refused to recognize the danger that was facing him. Once he had entered the senate, he was surrounded by senators holding daggers or knives. The first blow hit Caesar in his neck and drew blood. Then and other senators joined in and stabbed him repeatedly, until he fl to the floor and died. In total, he suffered 23 knife wounds. with his death, power shifted to his adopted son Octavian, who vowed revenge against the event of assassins. Eventually, several of the leading assassins were either killed or committed suicide. After a power struggle, Octavian strengthened his position as leader and ruled the empire for years. In the end, Caesar’s attempts to end corruption failed.Another event that shocked the world, was the assassination of the U.S president, Jack Kennedy. He was shot while riding in a motorway in a city of Dallas tax. Kennedy and his wife was sitting in an open car, waving to a large crowd of people when he was shot. They were sitting in an open car with no protect because the sky was clear. It had rained until ab out 10 am but then the sun came out. If the sky hadn’t cleared, they would have been a bubble car or clear roof, on the car. This would have prevented the assassination. Kennedy wanted it down so that he could be closer to the crow through they agree him. Another factor that contributed to his assassination was the round of motorcade through the city. Theround was published several days earlier in the local newspapers. The motorcade was passing through the downtown Dallas and round the shot corner near the building where the assassin worked.From that building, there was a clear view of president’s car. If the round had been different,the assassination probably wouldn’t have taken place. The president was struck by 2 bullets but it was the second one that probably killed him. That was the fatal shot. It opened a massive of room in this head. Sitting beside him, his wife’s last words to his husband were, Jack, Jack, can you hear me, I love you Jack. The assassin’s quick shots were incredibly accurate. If the fatal shot had been off by just a little, Kennedy might have survived. So if any of these factors had been different, history would have changed. Kennedy’s death disillusioned Americans who have been inspired by his vision for the future. With his death, a whole generation of Americans woke up to a reality where their dreams for a brighter future had been shattered.He might have been overconfident and unaware of the magnitude of the dangerous facing him.Unit 2-3 Dialogue 亲人去世I’m sorry to hear about your father. I hope he died peacefully.Emm. He knew it was coming and he had a good life. He’d been sick for about for about a year. Luckily, there wasn’t much pain.So how is your motherShe hasn’t taken it well.

Does she have many friendsShe has a few but she has never been very social. Maybe s he’ll get out a bit more now but I don’t think that’s very likely. She’s also beginning to lose her memory.Oh, that’s too bad. My mother is losing her memory too. Sometime she doesn’t know who I am. She mixed me up with my sister.Does she live by herselfShe did until about a year ago. Then we had her come and stay with us.How is that working out.It was ok at first but now with her memory problems, it isn’t working. We are thinking about putting her into a senior living community. It was expensive but they can provide her with spon.You may have to do that too. My husband and my mother don’t get along at all. You can’t relax when she’s around. When I mentioned it to him, he said he would consider it but only if it were for a very short time.Well, I’m sorry you have to deal with it. it doesn’t seem that there are any good choices.Emm, I’m afraid that’s right. We are getting older too. This is another reminder of our mortality. You are no longer children so now it’s our turn to take care of our par ents.The way I see is a reminder for us to enjoy life while we can. If you like, I can send you information about some senior communities.Please do. We need to start to making plans.There are waiting list to get into some of senior community.Unit 2-3 Reading 凯撒和印度的老年化Should a good leader be loved or feared This question is as relevant to leaders today as it was to Julius Caesar when he took control of Rome in 44 BC. How Caesar treated his enemies is a valuable lesson on forgiveness, arrogance, and absolute power.After Caesar seized power, he had to decide how to handle those who opposed him. Roman politics had always been bloody. The previous dictator(独裁者) had murdered 5000 of his rivals and confiscated(没收) their property after coming to pow er. Caesar’s enemies expected a similar punishment.But Caesar was determined not to rule through fear. If he were to reform the government, he would need the support of the people. So he made a fateful decision: rather than punish or kill his enemies, he offered them mercy and incentives. He didn’t seize their property, and he even rewarded some of them withhigh-ranking government positions.However, not all of his enemies wanted to be forgiven. Caesar’s rivals came from the aristocracy. Many had held power in the senate for centuries. By expanding and reforming the senate, Caesar had shifted power away from the aristocracy and taken it for himself. The high-ranking positions he had given as rewards had no real authority. For the aristocracy, to live without power was not forgiveness, but humiliation.Caesar should have known that many senators hated him, but his arrogance seems to have blinded him. After he made himself dictator for life, he proclaimed(正式宣布) himself a god and consolidated more power. These actions infuriated(激怒) his enemies and even his allies. However, he still considered many senators to be his loyal friends. He even dismissed his personal security force. Ironically, when he was assassinated, it was his good friend, Brutus, who led the plot.Perhaps it is better for a leader to be feared. If Caesar hadn’t let his rivals live, he might not have been murdered. But was forgiveness the problem Caesar’s reforms took power from the aristocracy, and his arrogance angered both friends and enem ies. Perhaps if he hadn’t been so arrogant, or acted like a god, he would have survived.Lack of adequate care for senior citizens is a real issue in India that cuts across economic and social strata(各阶层). Many of us have personally lived through and experienced it with our parents and elders.。

Atoms are the building blocks of matter.At the center of an atom is its nucleus which has a positive electric charge. Outside the nucleus are electrons which have a negative charge. Asteroids and comets are objects that obey our sun, but are smaller than planets.Asteroids that pass close to the Earth are called near-earth objects. The layer of gases just above the Earth’s surface is our atmosphere. The atmosphere is made of gases such as oxygen and nitrogen. Withoutan atmosphere there would be no life on Earth.If they collide with Earth they could cause an extinction event.A force can increase or decrease the speed of an object, and it can change the direction of motion. Theelectric force between the nucleus and the electrons holds the atom together.The two lines on the left intersect each other at a right angle which is90 degrees.The two lines on the right are parallel which means they never cross. The adjacent sides of a rectangle are perpendicular which means they meet a 90-degree angle.The opposite sides of a rectangle are equal and parallel which means they never cross.The area of a rectangle is the length times the width.A circle is a two dimensional figure with a radius and a circumference which is the distance around the circle. Thearea of a circle is Pi R squared, where R is the radius and Pi is the ratio of the circle circumference to its diameter.A sphere is a three dimensional figure with a radius and a volume which is four thirds Pi R cubed.All points on the surface of a sphere are equidistant from its center.A right triangle is a two dimensional figure with three side, two of which are perpendicular.To find its area, multiply the length of the two perpendicular sides a and b and divide by 2, A equals 1 half ab.A rectangle is a 2 dimensional figure with 4 sides.DialogueM: Have you finished eating yetW: No, I haven’t. Why are you in such a hurryM: I’m sorry, but you are such a slow eater.W: A slow eater Well, I try to enjoy my food. You just eat and swallow.I don’t see how you can even taste it.M: OK, I’m sorry.

U n i t3-1l i s t e n i n g偷窃They were locked up the safe and the only way to open the safe was with an 8-digits access code. Whoever got in the safe, must have back code.As far as he knew, nobody else had it, or have ever asked to use it to get something from the safe.Only 2 people in the company were authorized to have the code. He had the code of course, and so did his assistant, Sylvia. There was no reason for Salvia to take the documents, so he couldn’t imag ine that it was her. That would make sense and she was completely trustworthy.So somebody else must have the code and stolen the document.She had a notoriously bad memory so she kept a lot of notes.But Sylvia wasn’t that careless or irresponsible.She had probably stored the code somewhere on her computer and the theft was able to get it from there.But who could he have been. Suddenly, he realized that there was a new IT guy in the office. He maintained the company’s computer network and provide te chnical support for the staffs. Perhaps he was the guilt he wanted. If anyone could have done it, he certainly had the skills. He was a security expert and he had helped Sylvia stored something on her computer last week.Then john realized that nobody had done a proper background check on the guy. One of other engineers in the company had recommended him and he seemed nice. They had been in a hurry to hire someone for the position so they didn’t check this background very carefully. Suddenly, he had a bad feeling. immediately, he used his smartphone to check the company’s bank accounts. To his horror, he found that a large amount of money was missing from one of his accounts. There had a large withdraw earlier that morning, more than 75 thousand dollars. He then discovered that the money had been wired to an account in another country. So not only did the IT guy get the access code for the safe, but he also got the lodge information from the bank. This was a disaster. John immediately called the police and reported the incident. He also called the bank to see if they could stop the transaction. Unfortunately, they said it was too late. the transaction had gone through. Just then, john got an email with the subject line, from the IT guy. It showed smiley face and said thank you for being so stupid. Don’t waste your time trying to find me. I’ve left the country and will never return. Be thankful that I didn’t everything in the account. This should a good lesson for you. It was signed, your IT guy.Unit 3-1 dialogue 评论和建议Well, what did you think of my presentations.Did you want me to be frank? I know we work very hard on it.Yes, give me to it straight. I have my own opinion too. But I appreciate your commentsand suggestions.You said you had your own opinion about it. so how do you think of them.I thought it went ok at first. But I could feel there were some bad transitions(过渡).I think I spent too much time on some slides and didn’t express them well.I agree on most points. But to me, it was flat. 5 minutes into it I had a hard time paying attention.Flat? Do you mean my voice?Yes, that’s part of it. there is very passion alm ost like you were reading it. I’m sure you can do better.Do you have any suggestions?First, let me say I like the slides themselves. The designs were nice and easy to read. But one thing you didn’t do was engage with the audience. You focus on your slid es and didn’t address your audience.Oh, I was trying to but I guess I was too nervous. I didn’t want to forget anything. You have a great smile. You need to show that smile and expressions when you present. Make eye contact.When you present, I notice you always do that and your pause between ideas. Butit seems so easy for you.For me, I look at the faces in the audience. I watch their expressions. I really try to communicate with them. Once I do that, it comes naturally, because it becomes real communication.You seem to enjoy it.Well, I’m always nervous too before I get started. But once I contact with the audience, I’m ok.So contacting with the audience is the key. Focus on them and not me, right? Yes, well put. In fact, if you do that, you will have to adjust your presentation. It has to flow like in a read conversation. We have to respond to each other. And the pauses are so that the presentation can breathe.Hmm, it seems so obvious. But I’ve never thought of it like that. That’s a great advice. I wish we had talked before my presentation.If we had, you may not have been open like you are now. anyway, I’m sure your next presentation will improve. It takes practice like anything. Don’t be too hard on yourself.No, I won’t. But next time I will do better and I hope you there.OK, well, let’s get back to work.Unit 3-1 Reading 化石能源和哲学悖论Depletion of fossil fuelsA number of scientists are emphasizing the tremendous challenges that will soon be faced when the depletion of fossil fuel supplies coincides with(恰逢) an alarming increase in the global population. They highlight agriculture which is heavily dependent not only on gasoline to fuel machinery, but also on the petrochemicals necessary to manufacture synthetic(合成的) fertilizers and pesticides. Without these petrochemicals, crop yields would be only a fraction of what they are today. To assume that an abundant source of renewable energy will address this challenge is to ignore the vital non-fuel uses of petrochemicals.Then there is the challenge posed to the current levels of mobility. As a fuel, gasoline is unrivalled(无敌的) in its portability. Electricity requires bulky batteries and hydrogen is notoriously difficult to store. Biofuels might seem like an alternative, but the energy consumed when converting corn into bioethanol, for instance, greatly exceeds the output when the fuel is utilized. In any case, once we reach a crisis in the food supply, it will not make sense to divert food crops to other uses.Although there seems to be a widespread belief that the era of oil dependency is coming to an end due to some technological remedy(补救方法), this may be mistaken. Relying on such an assumption can lead to complacency(自满) and a failure to take precautions(预防措施). Experts may not be able to come up with solution that can lead to a pain-free transition. Scientists warn that relying on alternative resources might only support half of the global population. The absence of realisticalternative to fossil fuels will mean that the first priority will be to curb the demand for food.Petrochemicals are used to manufacture pesticides, which are good for agriculture. The meaning of catch 22One of the most interesting books of the 20th century was the novel, Catch 22. In the novel, the term has nothing to do with catching anything. It has a much deeper meaning, and it describes a kind of logical conundrum(难题) that’s worth exploring.First, it’s important to put the phrase into context. In the novel, a group of American bomber pilots is on an island in the Mediterranean. They face death almost every day when they fly their bombing missions. Many have already lost their lives; the remaining pilots know that it is only a matter of the time before they will be the next victims.One of the characters in the novel is a doctor. It is his job to see that the pilots are fit to fly. In particular, there is rule that says he has to ground anyone who is crazy. To ground them means to remove them from active duty so that they don’t fly.Some of the men believed in the principles they were fighting for. They were willing to give their lives for their country. But to others, this was crazy. They thought the whole thing was insane. One of them, Yossarian, wanted out. He was friends with the doctor, and he wanted the doctor to ground him.When Yossarian asked the doctor to ground him, the doctor replied: “you’re wasting your time, you’re not crazy”.Yossarian told him to ask one of the other pilots, Clevinger, to tell him how crazy he was. “There is no point. He’s crazy.” The doctor replied.” Crazy people can’t decide whether you are crazy or not.”“Clevinger isn’t crazy! he’s one of the sanest pilots here.”“So he’s obviously out of his head,” said the Doc.“He’s got to be close calls he’s had.”“well, if he’s crazy, why don’t you ground him?”“I can’t unless he asks to be grounded. That’s part of the rule.”“So all he has to do is ask?”“no, then I can’t ground him.”“So there is a catch,” said Yossarian, trying to get things straight.“Sure, there’s a catch,” said the Doc, with a slight smile. “Catch 22. If he asks, then he can’t be crazy. Only those who are crazy are grounded.”“there’s some catch,” observed Yossaria n.“it’s the best there is, ”the Doc replied.Unit 3-2 listening 流行病Despite advances in technology, one of the biggest threats to human survival comes from primitive(原始的) lifeforms. Infectious diseases are caused by microorganisms, such as bacteria, virus and parasites(寄生物). These organisms have no access to education or technology, but they present a huge challenge to humanity. That’s because they are adaptable. Just as adaptability has helped humans survive, it makes it more difficult to control infectious diseases. As conditions change, the organism which caused these diseases adapt and become stronger. There are several kinds of infectious diseases.Bacterial infections such as pneumonia(肺炎), are caused by bacteria. these infections can be treated by antibiotics(抗生素), which kill the bacteria. viral infections are caused by virus, such as the influenza virus. These can sometimes be treated by vaccines, such as flu vaccines. An example of parasitic(寄生虫的) infection is malaria(疟疾). Malaria is caused by parasites transmitted to humans by infected mosquitoes. Once inside the body, the parasites can be difficult to kill or control. And also, these parasites are also adaptable.How serious are infectious diseases. Considered what happened in 1918, the influenza pandemic(流行病). It started in the fall of 1918 with what seemed to be something no more serious than a common cold. In the next 2 years however, it infected a fifth of the world’s population. In fact, it turned out to be the most deadly epidemic in history, killing between 20 and 40 million people. The influenza virus that caused it was much stronger than previous influenza viruses. Its molarity rate was 2 and a half percent compared to a point 1 percent in previous epidemicviruses. Its stuck quickly with no mercy, sometime killing people within hours. School and business closed in many places, and people wore masks to prevent the transmission of the virus through the air. What was unusual about this pandemic was that it was most deadly for people age 20 to 40, rather than the elderly and young children.Now a century later, we have flu vaccines that have reduced the severity of the epidemics. These vaccines needed to be updated every year because the virus changes and new strange immerge. What researchers fear is that a new strange will develop and cause another pandemic. Once an outbreak occurs, transmission of the disease will be even faster than the before. An unattempt consequence of our improved transportation system will be the speed in which an epidemic can spread. Experts predict that the public health systems will be overwhelmed and unable to react quickly enough. So the best defense will be to prevent an outbreak from occurring. This will require global cooperation and the sharing of data. It may also require changes in how humans interact with animals. Animals such as birds and pigs carry viruses that may mutate(变异、突变) into a strain(一株) that can infect humans. Such a new strain could lead to another pandemic well before a new vaccine could be developed. Since diseases epidemic don’t stop at national boarders, this is a global issue requiring a global action. The threat of a global epidemic is another example of why we must learn to live together.Unit 3-2 dialogue 子女教育方式You know, my husband and I are having a terrific fight over how to rise our son.What about?He’s only 4 years old.My husband I’m putting too much pressure on him. He thinks it’s wrong thing to do.I wouldn’t know. I’ve not even married yet. That’s my problem. I wish I had a husband to disagree with.Well, he thinks it’s important for kids to have time to be bored.Bored?Yes, he really said that. Can you believe it?Why did he think so? Did he have time to be bored when he was a boy.Well, he grew up in the countryside. He said he had to find things for himself to do. He feel sorry for his kids these day because their days were so structured. Hmm, I see it’s point. But things have changed a lot s ince he was a boy. That’s exactly what I told him. Then he started to get angry.That does n’t sound like him. He’s usually so calm and reserved. In fact, I can’t ever remember he and his express in opinion.Well, the other day our boy said he didn’t like one of our teachers. It’s a English teacher. And then that got my husband’s attention.What happened?He got angry and he said he wasn’t happy with all the emphasis on English and math. He said I should find some places for our boy to do more of what he wants to do. He said he’d find the class the teacher who encourages kids to explore things. That sounds a bit idealistic.That’s what I told him.Then he said it’s important to learn how to be independent and not always depend on being told what to do. He said that can develop creativity and the love of learning.Certainly. What happens when he is behind of other kids in school? won’t he be discouraged?He said he wanted the boy to deal with it and see what happens.Some people are more competitive and some aren’t.Anyway, it’s an interesting point of view. It may work for some kids and not for others. What about your boy? What do you think?He has a good imagination. sometimes he talks oneself that he really likes music and dancing. He has a lot of energy. Sometimes it’s exhausting to be around him.I guess if I were you, I just give him a lot of choices and see what he is interested taking in. and he needs a place where he can use all that energy.Ye s, that’s what my husband wants to do. I just get nervous because all his friends are taking classes. I don’t him to fall behind.I don’t know what to say. Maybe you do some researches and what others advise. I’m sure you are not the only one facing this problem.At least your husband is taking an interest.If I ever get married, I hope my husband will be as involved as yours. But he has to help you with this and just complaint.Yes, that’s what we are fighting about. I can’t be expected to do this on my own. You have to do this together.Good luck. And wish me luck in finding a husband, ok.Unit 3-2 Reading Wi-Fi诞生和人工智能Hedy Lamarr a Hollywood star and mother of Wi-FiHedy Lamarr was born Hedwig Eva Naria Kiesler in 1914 in Vienna, Austria. By the time she was a teenager, she had decided to drop out of school and seek fame as an actress. She first appeared in a German film in 1930. She was attractive and talented enough to be in three more films in 1931, but it was her controversial film “Ecstasy”(入迷) that brought her worldwide fame as an actress.In 1937 she fled from her country and secretly moved to Hollywood, where she reinvented herself. She changed her name to Hedy Lamarr, with the nick name” them ost beautiful woman in films”. However, Lamarr defied(挑战) the leading-lady stereotype by also pursuing an interest in mathematics and engineering. She soon took up inventing. Her earliest inventions included an improved traffic stoplight and a tablet that would dissolve in water to create a carbonated drink(碳酸饮料). With the ongoing world war, Lamarr was inspired to contribute the war effort. She designed a radio guidance system for torpedoes(鱼雷). With the help of composer(作曲家) George Antheil, whom she met in 1940, she discovered a way to break up signals and transmit them over different frequencies. Using a method similar to the way player piano work, they designed a frequency-hopping system(跳频系统) that would continually change the radio signals sent to a torpedo. While others, including Nikola Tesla, had explored similar ideas of frequency hopping, Lamarr and Antheil obtained a patent for their invention in 1942 for what would become known as spread-spectrum(扩频) technology.Although the US Navy did not adopt the technology during the war, it was used during the Cuba n Missile Crisis in 1962. For decades Lamarr’s technology remained behind the scenes, but ultimately it led to the creation of today’s spread-spectrum communication technology, such as Wi-Fi networks, mobile phones, GPS and Bluetooth technologies.Lamarr and Antheil eventually received several awards for their lifetime creative achievements that contributed so much to society. They were inducted(就任;授予) into the national investors Hall of Fame in 2014, after her death in 2000.The challenge of AIThe internet and smartphones have changed the world and how we relate to each other. Instead of meeting in person, we increasingly interface through handheld devices. In a sense, real people are being removed, replaced by technology and virtual friends. Some people even say that they prefer to confide in(信任) their virtual friends rather than their real friends!AI, or artificial intelligence, is another technology that is highly disruptive(破坏的). With AI, smartphone are other devices will have even more capabilities. They will be able to converse with us and tell us jokes. They may even become personal tutors. They will know what kind of problems we have, our preferences, and any content we want to learn or practice, they will be able to adapt to our needs and be available at any time. And all this will be at less cost than using a human. In fact, the substitution(替换) of AIs for human labor has the potential to transform our world. Experts warn that smart machines may cause widespread unemployment. Many works will become redundant(多余的), replaced by machines that can perform cognitive tasks better than people. An even greater danger is that they will develop personalities and become more interesting than people. Work us already underway(起步的) to produce AI companions for lonely people.Are these development something to worry about or something to welcome? How are they different than developments in the past, such as the industrial revolution? Cars replaced horses; machines and industrial robots replaced factory workers.Since the shift to AI is inevitable, the challenge for policy makers will be to help existing workers acquire new skills. Future generations must be prepared for a workplace populated by AIs that will continue to develop and take on new tasks. Are we up to the task?Unit 3-3 listening 斯坦福监狱实验In 1971, psychologist created one of the most important experiment in psychology. The experiment known as the Stanford prison experiment, look at the impact of situation in human behavior. The researchers, led by Philip Zimbardo, wanted to know how situations could affect how people behave. In participle, we wanted to know if good people would change their personalities and lose their values. In the experiment, participants were divided into 2 groups. One group became prison guards and the other group became prison inmates. The experiment was set up in Stanford university’s psychology building. A group of 24 students was chosen to play the roles, 12 guards and 12 prisoners. The participants came from a large group of volunteers who wanted to participate in psychology experiment. Those who were chosen had no criminal background and had no significant medical or psychological problems. They agreed to participate in the experiment for 1 to 2 weeks’ period. The prisoners had to remain in prison 24 hours a day during the experiment. Guards are * into 3 and were assigned to work in 8-hours shrifts. Unlike the prisoners, they were free to return their homes between shrifts. Hidden cameras and microphones were used to observe the prisoners and guards. The simulated(冒充的) prison included 3 small prison cell, 6 feet by 9 feet. Each cell had 3 small beds and held3 prisoners. There was a closet that served as a solitary confinement room(禁闭室). This was used to isolate prisoners who needed to be punished for bad behavior. Guards were instructed not to physically harm the prisoners by any way. prisoners were to be addressed by assigned numbers and never by name. to prevent eye contact with the prisoners, guards wore mirror sunglasses. This was done to dehumanize the relation between guards and prisoners. Though the experiment was designed to last for 14 days, it had to stop after just 6th days. It had to stop because what was happening to the participants. The interactions between the prisoners and guards had become hostile and degrading(有辱人格的). The guards had become aggressive and brutal and the prisoners were passive and depressed. As a result, five of prisoners had to be released early because of the severe negative emotions. Even the researchers were affected and they began to overlook what was happening. Instead of halting the experiment, they led it continue. They themselves, had become dehumanized by the situation he had designed. Finally, they realized the experiment had to be stopped.What the experiment demonstrated is the powerful effect that situation can have on human behavior. Given a position of power, human can begin to behave differently than they normally were. They can become to behave in an aggressive manner while those with no power can became passive and depressed. In other words, the experiment shows that situation can cause abuse of behavior.There are some important criticism s of this experiment. One criticism was that it is an example of unethical research. It went on longer than it should have. It isalso unrepresentative since the participants were mostly white, middle-class, males. Despite the criticism, the experiment remains an important study of human behavior. Recent example of the Stanford effect may include the treatment of prisoners of war by American soldiers in the Iraq War. Other possible examples including boiling in school and gun behavior. According to the head researcher, *, it helps to explain how ordinary people sometimes turn bullying evil. If situation do influence people behavior, then managing situations can be a way of controlling people.The prisoners had to remain in prison for the duration of the experiment.Unit 3-3 dialogue 跳槽和忠诚Hi, what’s so urgent. When you message me, you seemed really upset.Yes, i was. I was confused and I still am. I need your advice. You’ve known me for a long time.You are my best friend. So what did it?I’ve been offered another job.Oh, that’s usually a nice thing. So what’s the problem?The problem is that they are as stronger as competitors.Oh, you mean Beta Crop.Right, there may be a great offer. More than double than my present salary. Ah, i see. So the dilemma you’re facing is whether to take it or not.Yes, that’s it exactly. It will be a betrayal of everyone I’ve been worked with for more than 10 years. It makes me sick to even think about it. But I’m really tempted. It’s a lot of money.Look, I’ve known you since our student days. If you took that job, you would be betraying yourself.Yes, i know that. I’m with they hadn’t made me such an offer.So why are you asking for advice? If i were to said it’s OK to take the job, will that give an excuse to take it? You otherwise have to live with yourself. Honestly, what would you do?If i were in your situation, i would probably feel the same way. And to be honest, i hope i would be able to stay true to myself. I suppose if my family were very poor and in trouble, I’d be tempted. But even then, to betray my friends and colleagues, who would I be. It’s a real test of character.Yes, those are my thoughts. And I’m not sure what my wife will think.Look, i know your wife. I think she will be proud of you if you do the right thing. Yes, she probably will. And in the end, I’m not sure i can treat the *. they are a branch of cutthroats. They have no a*.So i think the answer is clear. And one more thing, i hope you can do the right thing even for me. We need the people to stand up and do the right thing. If you were to betray yourself, it would discourage everyone who knows you. You have a lot of influence and people look up to you. I don’t want to lose faith in humanity. Thanks. That’s what i thought you would say.I would be disappointed if you thought i say anything different.I will do the right thing whatever the consequences. I know there will be people who will think i being a fool for turning it down.Yes, but there are the ones who matter. Cheers! To you and saving the world. Ha Ha...Unit 3-3 Reading 电影&数字科技Whatever happened to characterMedia and technologies are reprogramming the human brain, changing how we think and live in significant ways. Nobody really knows how this will affect the future, and few seems to care. The tendency is to let it happen and go with the flow, despite warnings from some that all is not well. Nobody can stop progress. Still, it’s fun to reflect on changes to see what might be lost.Looking back to classic movies and comparing them with what we have today, we see many similarities. However, there are major differences. In particular, classic movies succeeded with few if any special effects. The camera focus more on faces and expressions, like in the movie Casablanca. Violent actions were seldom shown in gruesome(可怕的) detail but were inferred(推断) from the situation. Storylines focus on character and personal; dilemmas. Much was left to imagination. And of course, sex was hinted at(暗示) , but never shown, except in seedy(破旧的) theaters. Some of the best movies too place in a single location, such as on a lifeboat or in a jury room. Would such movies draw an audience today? Those movies depended on writers who could build drama into the interactions between characters who had psychology. It also required audiences to have a similar interest, who could empathize and be moved. Do those audiencesexist today?Flash forward to the present. So many movies are filled with fast-moving special effects, explicit violence, and lots of sex. We have become voyeurs(窥淫癖者), addicted to getting thrills(兴奋感) through the experiences of others. Subtle emotions? Psychological dilemmas? Or just plain escape! Of course, there have always been escape movies - Bollywood movies with stars dancing in the streets. It’s just the balance which has shifted.Classical music and jazz players for more than a few minutes. People concentrated and took time to enjoy and savor(品味) it. But now, immersed in media, there is no time. Experiences are quick and shallow, measured by the number of likes. We flee into the noise, perhaps to escape from ourselves.What do you think? Or has it always been this way?Digital intelligenceThe impact of technology is widespread and accelerating. Experts predict that 90% of the world’s population will connect to the internet within 10 years or less. Evolving technology has become an unstoppable force. Reshaping our societies, ignoring national borders, and interconnecting economics. There doesn’t seem to be any way to control it. However, one fact is certain: our kids are at the center of it. Today’s children areborn into a digital world. They use technologies and media from the time they begin to walk. Sometimes they have difficulty distinguishing between the virtual and the real worlds. In fact, children spend more time immersed in technology than they do with people, including their parents. It is estimated that they spend an average of hours a day in front of some sort of digital device.With the ever increasing amount and flow of information, digital proficiency(精通) may be the next survival skill. Therefore, it is essential that children learn how to develop that skill without losing themselves in the process. Guiding them is a challenge we need to face. First, we need to realize that with so much exposure to content, there are both opportunities and dangers. What and when is something appropriate for children, and at what age? Who decides? Media is so pervasive and accessible, yet there is no consensus about what is suitable. People have different perspectives, not only about content, but also about how to govern access.Governments must also decide what controls are necessary. Policies must be put into place and standards set. Whatever the decisions, the consequences will be enormous.It seems naive to sit back and let children make their own decisions and explore whatever captures their fancy. So technology has presented us with。

U n i t1-1L i s t e n i n gCathy usually gets up at 6:30, but this morning she didn’t hear her alarm. As a result, she overslept. She didn’t get up until 7:00, 30 minutes later than usual. As a result, she didn’t have time to cook breakfast for her children.Today Cathy and her kids left home early. They usually leave home at 7:30 but today they left home at 7:15. They left early because they had to buy breakfast on their way to school. It usually takes 45 minutes to drive her kids to school but today it took longer. It took them longer because they stopped for breakfast along the way. It took 15 minutes for them to have breakfast. They ate at a little coffee shop along the side of the road. After eating breakfast, they got back into their car. On most days, th e traffic isn’t too bad in the morning, but this morning it was much worse than usual. The cars were moving very slowly. As a result, it took them longer than usual to get to school.One of her children got to school on time but the other two were late. They were late because their schools are farther away. They were both about 10 minutes late to school.When Cathy finally got home, she cleaned her house as usual. She vacuumed the living room and cleaned the bathroom. Then she talked with her friend on the phone as usual.When she finished talking with her friend, she got into her car. She put the key into the ignition and tried to start the engine.

On most days, the buses come on schedule but sometimes they don’t. Yesterday for example, several buses were late. This is because the traffic yesterday was much heavier thanusual.Bus number 38 was supposed to come at 8:40 but it was 5 minutes late. It didn’t come until 8:45. Bus number 60 was supposed to come at 8:30, but yesterday it didn’t come until 8:40. It was 10 minutes late. Not one bus came early. As a result of the delays, one man got on the wrong bus. He wanted to go to the airport so he wanted to get on the bus number 38. He expected it to come at 8:40. Instead he got on the bus number 60, which came at 8:40. He didn’t notice that it was the wrong bus. It d idn’t go to the airport. As a result, he missed his flight.Unit 1-1 vocabularyWeddings are where two people get married.

It is a beautiful, rotating sphere. The side facing the sun is in daylight. The side facing away from the sun is in darkness. For example, when it’s daytime in US, it nighttime in China. In fact, there’s 12-hour time difference between Bos ton and Shanghai. When it’s midnight in Shanghai, it’s noon in Boston. The earth rotates from west to ea st. To know which direction is west or east, watch the sun.The sun travels through the sky from east to west. The sun comes up in the east and goes down in the west. Again, this is because the earth rotates. It takes 24 hours for the earth to make a complete rotation. And that is the length of one day.Because of the earth’s rotation, the earth is divided into time zones. Some countries, such as US, has several time zones. When it’s 10 am in New York, it’s 7 am in San Francisco. Europe and the US are separated by several time zones. When it’s 5 pm in Paris, it’s 11 am in Boston. So there is a 6 hours different between Paris and Boston. One large country, China, has just one timezone for the whole country. As a result, at the same time, some parts of the country can be dark and other parts can be light.As you travel around the earth, the time changes. The time of day depends on your location on the planet. When you travel east or west, you may cross several time zones. For example, if you travel from Beijing to Los Angeles, you may cross 8 time zones. That means, when it’s noon on Sunday in China, it 8 pm on Saturday in Los Angeles. For travelers, this means it can be very difficult to sleep after a long flight. The clock may say 8 pm, but for your body, it’s noon. This is called jet lag.Kim is a popular Korean actress.

Winter sports include skiing and ice skating.Summer is the hottest season because the sun is at the highest point in the sky. Many people like to go swimming in summer because of the hot weather.Spring is the season when the weather gets warmer each day. For many animals, new life begins in the spring. Autumn is the season when the weather begins to cool and the days begin to shorten. Autumn is when the trees turn many colors and leaves fall to the ground.Rainy season is the season when some countries get most of the rainfall. Rainy season usually lasts one or two months.Unit 1-2 dialogueHi, I’m sorry to be late.What happened? You were supposed to be here an hour ago.Yes, I know.

They show how these 2 people spend their days, not including weekends.The one on the top shows how Emma divides up her days. She is a designer whoworks for a company.As Emma’s graph shows, the biggest portion部分 of her day is spent working.She works an average of 8 hours a day, which is one third of her day.She gets an average of 6 hours to sleep which is 25% of her day. That’s less sleep than Martin gets.According to his graph, he gets an average of 7 hours to sleep which is about 29% of his day.On the other hand, Martine who is engineer, works more hours than Emma does. Martine average 9 hours a day at work co mpare to Emma’s 8. That’s 37.5% compare to 33%.Other factors shown in the graph included time for meals and commuting to work. Other activities include getting dress and doing household chores such as doing laundry and paying bills.As you can see, for Martin, commuting is taking a large amount of his time.If he could reduce his commute time, he will have more time for other things. And it isn’t just the time.When the traffic is really heavy his commute is stressful.It will be great if he can work from home one or two days a week. He life willbe more enjoyable.And we look at Emma’s graph, we see she probably needs more sl eep.Perhaps, she should spend a bit less time socializing with her friends.On the other hand, socializing with her friend is something she really values.As for putting on makeup, she isn’t willing to change that.For her, exercising, socializing and staying beautiful help her deal with the stressful work.In conclusion, Emma and Martin both wish there were more hours in a day.This next graph shows how various factors compare important to 1350 jobs applicants.Applicants were between 20 to 25 years ago.They were asked to list which factors were most important for a good job.As the graph shows, money was the most important factor for 25% of the applicants. However, other factors are also important. The second most important factor was the work environment.In other words, for many, money is everything.People want to like where they work.In fact, if we combine working environment and co-workers, the total is 35%.This is well above the 25% for salary and benefits.Taking together, they are more important than salary and benefits.Career path is also important especially for younger applicants.They want to see that their job helps to build a successful career.For older workers, this may not be as important.Older workers often put the higher value on the balance between life and work.

懂你英语原文Level7Unit1So in college, I was a government major, which means I had to write a lot of papers. Now, when a normal student writes a paper, they might spread the work out a little like this. So, you know --you get started maybe a little slowly, but you get enough done in the first week that, with some heavier days later on, everything gets done, things stay civil.And I would want to do that like that. That would be the plan. I would have it all ready to go, but then, actually, the paper would come along, and then I would kind of do this.在大学，我读的是政府专业。

也就是说，我需要写很多的论文。

一般的学生写论文时，他们可能会这样安排：(看图)你可能开头会慢一点，但第一周有这些已经足够。

后期再一点点的增加，最后任务完成，非常的有条理。

我也想这么做，所以一开始也是这么计划的。

我做了完美的安排(看图)，但后来，实际上论文任务一直出现，我就只能这样了(看图)。

And that would happen every single paper. But then came my 90-page senior thesis, a paper you're supposed to spend a year on. And I knew for a paper like that, my normal work flow was not an option. It was way too big a project. So I planned things out, and I decided I kind of had to go something like this. This is how the year would go. So I'd start off light, and I'd bump it up in the middle months, and then at the end, I would kick it up into high gear just like a little staircase. How hard could it be to walk up the stairs? No big deal, right?我的每一篇论文都是这种情况，直到我长达90页的毕业论文任务，这篇论文理应花一年的时间来做，我也知道这样的工作，我先前的工作方式是行不通的，这个项目太大，所以我制定了计划。

L5 Unit 1-1 ListeningJessica was 35 years old. She graduated from middle school 20 years ago. This year her middle school class had its 20th year class for reunion. All of her classmates and teachers were invited to attend. It’s to going to be held at the hotel, near where their school used to be. Like many other buildings, the school had been torn down. It had been replaced by some of the apartment buildings.At first, she wasn’t sure if she could go to the reunion. One reason was that there wasn’t anyone in particular that she wanted to see. Another reason was that she was very busy. She was a working mother, with a boy 8 years old and her husband who was rarely at home. Going to the reunion meant that she would have to arrange someone to tak e care of things while she was away. That wouldn’t be easy. She didn’t want to take her boy with her and her husband wouldn’t take time off from work.Then she got a message from Sharon, one of her classmates. Sharon was contacting people from their class and urging everyone to come. In the school days, she was class monitor, and now she was helping to organize the reunion. They exchanged the messages and Jessica said she couldn’t make it. Then Sharon gave her a call and they talked for almost an hour. Sharon reallywa nted her to come and so did a couple of Jessica’s old friends. They were all wondering how she was doing. None of them have seen or heard from her since graduation. They were especially curious since she hadn’t gone to their first reunion 10 years before.Jessica decided to arrange things so that she could go. Her husband finally agreed totake care of things while she was away. He agreed to do it because her mother had offered to come and stay for a while so Jessica could attend the reunion. Since he and h er mother didn’t get along, he decided to change his schedule and work from home for a few days. He really didn’t want her mother to come though he didn’t say so. When she got to the reunion, she was shocked. Everyone had aged so much and many of them were out of shape. Some who used to be good-looking had lost their looks completely and others look much better and before. It was strange how time had changed people in such different ways. Anyway, she decided that since she was there, she would try to enjoy it.L5 Unit 1-1 vocabularyTo replace something means to put something else in its ways.

When she arrived, she wasn’t sure she was in the right place. At first, she didn’t recognize anyone. She felt a bit awkward and out of place. But it wasn’t before a strange man came up to her. He was already losing his hear and he was wearing thick glasses(深度眼镜). Don’t you remember me? He asked. When he said who he was, she barely remembered him, especially he has changed so much. Then he told her that he had always had crush on her. He said she looked beautiful and he immediately took a selfie of them, with his arm tight around her waist. This made her felt a bit strange. She smiled at him and pretended to be happy to see him. But in fact, she was sure how to react, thought he seemed nice. She finally excused herself and went to the ladies’ room. She was beginning to regret to having come to the reunion. She had always been shy and she still was. When she returned to the party, Sharon invited her to sit at her table. Dinner was going to be served soon and some of the classmates were going to give speeches. Sharon next was also got to say a few words too because people were curious. This was a surprise. Jessica had never been very popular and she didn’t think anyone had noticed her. She had always felt like an outsider, with only a couple of close friends. Still, she had been one of the best students and people remembered her. As the evening wore on, Jessica began to really enjoy herself. She told to her old friends and was amazed by how some others had changed.For example, Tom used to be good looking and athletic. He was one of the most popular students, and star basketball player. His one problem was math. He had hadhard time in math especially in geometric. This is because he wasn’t a logical thinker. Except for basketball, he didn’t want to d o anything, unless it was easy.

Betty has a nice husband who seems to adopt her. The one tragedy in her life happened about 5 years ago when she lost her daughter to a rare form of cancer.

Betty had had such high hope in tremendous energy as a girl, but things didn’t work out.And then there was John. John used to be the school bully. He had been big, strongand mean. He hadn’t been nice to any body. It seemed that he was always angry and ready to hit someone. After graduating, he joined the army and went overseas to fight to a war.

He was working for an organiz ation that provides support to elde rly people. From Jessica’s point of view, john had turned out to be a wonderful surprise.

There were very few frozen meals available at the time and none of them were vegetarian or organic. There was a gap in the market.

Mysteries are things we don’t understand, such as how the Egyptian pyramids were built. In fact, we are surrounded by mysteries. What we know about the world, seems like very little. Scientists tell us that what we see in the universe is only a small part of what is there. The rest is invisible, including dark matter and dark energy.These two unknowns made up around 95% of the universe. Evidence for their existence comes from their effects on what we can observe, such as the motion and positions of the distant galaxies.Yet thought we know very little, we are able to build airplanes and communicate with smartphones. In some ways, we humans are very smart or at least we think we are. We still need to face big issues, like climate change and that’s going to be a huge challenge. The challenge for humans will be our abilities to adapt to our changing environment.What about other form of life? How do they adapt? Seasonal variations, for example, can be one of the greatest challenges for animals to overcome. Overcoming such challenges will be a great achievement but hardly easy. Some birds migrate thousands of kilometers each year, to deal with seasonal changes. These migrations are amazing.Birds don’t carry maps or compasses, yet they know where to go. They had developed their abilities to see the earth magnetic field. This ability is a wonder of nature. It takes advantage of the fact that the earth is like a huge bar magnet.It has north polar, which is positive and south polar, which isnegative. Somehow the birds are able to see this magnetic field and use it to their advantage.And even the way birds fly together is amazing. many migrating birds fly in a V formation. They do this to conserve energy. In a V formation, birds can use the energy of the birds in front of them. This energy comes from the air currents, generated by the wings. Conserving energy is necessary for the birds to survive in long journey. how do the birds know this? It’s truly amazing how the birds know this.Another amazing example of survive animal is the Salmon. Salmon spent most of their lives in the ocean which is saltwater. Yet, when it’s time to breed, they do so in fresh water rivers. Salmon can adapt their bodies to survive in both saltwater and freshwater. When it’s breedi ng time, they returned to the same river where they were born. It seems as if they had built-in map that guides them for hundreds of miles.Once they left the salt water, they don’t eat. They are determined to finish their journey despite of many obstacles. They swim against strong currents, jump over waterfalls and try to escape claws of hungry bears. Many die along the way but enough of them survive to breed and reproduce the next generation. Once they had lay their eggs, they die, having completed their journey. It seems that their purpose in life is just to reproduce.Migration takes the animals to new, more favorable environments when seasons change. Some of these journeys are long and dangerous, along routes with no obvious landmarks. The longest migration is that of the artic tern. It flies from polar to polar, twice a year. If a tern achieves its average lifespan of 20 years, the distance it hasflown will be equivalent to a journey to the moon and back.Humans also migrate, but seldom if ever for seasonal variations. unfortunately, human migrations are often due to human activities. Since the beginning of the 21st century, large scale migrations had become a global problem. Millions of migrants have had to leave their countries and look for new homes. Many have died along the way or left these refugees in camps until they are admitted into a new country. So, the question remains as to how our global communities will face these challenges.L5 Unit 1-4 vocabularyTo criticize someone is to point out their false or mistakes. Some people appreciate constructive criticism, which can help them develop their skills.To praise someone is to let them know they have done a great job. Some people expected to be praised when they perform well.To apologize to someone is to admit that you have done something wrong or hurtful. One way to apologize is to say you are sorry. I f your apology isn’t accepted, it means the person hasn’t forgiven you.To order people to do something means to use your power or position to get them to do it. Many people dislike being ordered to do things. In many cases, it’s better to make a request than order someone to do something.To encourage someone is to support their efforts and help build their confidence. A good teacher encourages students to do their best. To discourage someone is to get away their confidence.There are many cycle in nature, such as the circles of seasons. A cycle is a series of events that repeat, such as the daily cycle of light and dark.To evolve means to change or improve over a period of time. In biology, the series of evolution advanced life forms such as such as humans, have evolved from lower form of life.A force of attraction brings two objects closer together, such as the force of gravity. A force of repulsion pushes two objects away from each other, such as the force between two electrons.To transform means to change from one form into another. A transformation occurs when an object takes on(呈现) a new appearance or structure.To inherit something means to get it without having to ask or work for it. A child from a very rich family may inherit a lot of money.The number of times a cycle repeats itself within a period of time is its frequency. Gravity is a force of attraction between two objects with mass.L5 Unit 1-4 dialogueExcuse me, do you have a minute?I’m sorry, not right now. I’ll be free about in 15 minutes. Could you come back then? No, I’m afraid we have an emergency upstairs.Can’t you handle it?No, I think it will be best if you were there.Ok, I’ll finish this call and be right with you.Ok, what’s it?Kevi n and Bob are shouting at each other and it’s upsetting everyone.Oh, not again.Both two have got to grow up. Who started it?I’m not sure but they were even pushing each other.Ok, this is unacceptable. You run on ahead and warn them that I’m coming.I want them to calm down before I get there. Can you do that?Ok, I’ll do what I can to calm them down. But you know Keven, he’s such a hard heart.Ok, Keven, I’ve warned you before. This is got to stop.Yes, I know. But Bob doesn’t cooperate. He’s impos sible to work with.Even so, you can’t go around pushing people. That’s no way to handle things.If you were n’t doing such a good job, I’d have to let you go right now. Your behavio r just isn’t acceptable.Yeah, I understand and I’m sorry. I just can’t stand working with him.I’m sure what to do. What were you do if you were me? Do you have any suggestions? To be honest, if I were you, I wouldn’t have the two of us working in the same office. I know Bob has been with the company longer than I have but h e’s doing a terrible job.
