The respiratory system includes the nose and lungs. It brings air and oxygen into the body and removes carbon dioxide. The lungs are where oxygen enters the bloodstream, and carbon dioxide is removed.
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 the habitats of many plants and animals. Cutting down forests and polluting rivers destroys the habitats of many forms of life.

懂你英语Level4 Unit 3 Part1it 3-1 listening时间花费Look at these 2 pie graphs. 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 who works 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 will be more enjoyable. And we look at Emma’s graph, we see she probably needs more sleep.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.

This is how the plant reproduce.For reproduction to succeed, the pollen must be transferred from the male part of the flower to the female part. Many plants depend on the pollen for reproduction. This included many fruits and vegetables.Beside honeybees, there are many other pollinators including birds, insects and other kind of bees.Without enough pollinators, many of our favorite fruits and vegetable will become more expensive and hard to find. This included almonds and cherries.Honeybee are important pollinators and play an important role in agriculture.Beekeepers are people who keep honeybees.In addition to collecting honey, some beekeepers provide pollination services for farmers.They do this by raising and managing colonies殖民地of bees.Farmers need colonies to pollinate their crops.Beekeepers can provide and manage of bee colonies to farmers.Honeybees are social insects that live in colonies.A bee colony consists of a queen bee, male drones 雄蜂and thousands of male worker bees.Each colony also contains eggs and immature未成熟的bees in various stage of development.The number of bees within a colony depends on the seasonal changes.A colony’s population increases during the warm season and decreases during the colder season.In recent year, many bee colonies have collapsed or disappeared.A bee colony collapses occurs when a majority of bee in colony disappear and leave behind the queen.Some beekeepers have reported losing 30 to 90 % of their colonies.This loss of bee colonies can cause significant problems for farmers who depend on them to pollinate their crops.In some parts of the world, a shortage of bees has increased the cost of renting bees by up to 20%.There are several possible causes for bee colony collapse. One possible collapse is the use of new pesticides农药. Other possible causes include infections from viruses, genetic factors遗传因素and malnutrition（营养不良）. Changing weather patterns may also play a role as summers get hotter and winters get colder.These changes in weather may weaken the bees, making it more difficult for them to fight infections.Whatever the causes of colony collapse, it’s important to un derstand that many parts of our world are interdependent.Changes that effect on one species may have serious effects on other species.A change to our environment, can start a chain of event that is difficult to predict.In any complex system such as the earth environment, small changes can cause a un consequences.The danger of un consequences is something that we all need to understand better.L4 Unit 3-3 vocabulary 商品、服务和工作Goods and services supply what people need or want.Goods are things such food and clothing.Services included things such as health care and police protection.A country needs natural and human resources.Natural resources include fresh water supplies, farmland and energy sources such as oil and wind.Human resources includes a skilled workforce that can produce goods and services.Once we had supplies of goods and services, they need to distribute throughout the country.Highways and railways are both way to transport thing from one part of country to another.Electricity are distributed through a system of transmition lines.We live in an age of advertising.Advertising lets people know about goods and services.It educates people about a product being advertised.Trade allows for the exchange of goods and services between different countries.Exports are goods and services that are sold to another country.Imports are goods and services that are brought from other country.For example, many countries import oil from countries such as Saudi Arabia 沙特阿拉伯.Employees are the people who work for a company.Some employees do basic work such as operating a machine or driving a track.People who hire and direct the work of other are managers.Interview is one way to find out about a person who applies for a job.In an inte rview, the applicants can ask question about a company and company can find out about a person’s skills and experience.An entrepreneur is someone who starts a company.Entrepreneurs often have new ideas and ways of doing things that can give company advantage.Salary and benefits are used to attract new employees into a company.If the salary and benefits are good enough, employees may take a job and stay with the company.Benefits includes vacation time, health insurance and bonuses for employees who do a good job.When apply for job, it’s important to have skills and experience needed for the job.Developing and increasing skills and experience is good way to prepare for a job.Each job a person has is an opportunity to learn new things and develop new skills.Advertises try to increase to the demand for a product or service.Education and training are ways to develop a skilled workforce unforeseenL4 Unit 3-3 dialogue 谈论租房与房东You don’t look g ood, is something bothering you？Yes, it’s my landlord房东.Oh, is it something wrong with your flat.No, that’s not something wrong with the flat.

懂你英语L4-Unit2 1 Extinction EventsLevel4 Unit2 1 ListeningExtinction EventsThe Earth was formed about 4.6 billion years ago.The first life appeared about a billion years later.The first plants didn't appear until around 2 billion years ago. Until about 580 million years ago, life forms were small and microscopic. Since that time, life has evolved into many different types, or species. However, scientists estimate that more than 99% of them are now extinct.There have been several extinction events in the history of the Earth. In an extinction event many life forms, or species of life, die out. The causes of mass extinction events are unsolved mysteries. These events are not predictable and can happen at any time. Scientists think that some of them were started by asteroid impacts or volcanic eruptions. Events like these 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 all species on the planet died out. When the asteroid hit the earth, it started a chain of events. A chain of events is a series of events linked together, like a chain.This particular chain of events happened over a period of months and years. When the asteroid hit the Earth, it caused a huge cloud of dust to enter the atmosphere. This cloud of dust blocked the sun and darkened the Earth for many months. Without enough sunlight, 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 have played an important part in the evolution of life. In fact, some extinction events have helped to accelerate evolution. For example, some mammals lived through the age of the dinosaurs, but they couldn't compete. When the dinosaurs were removed, the mammals were able to compete more successfully. Once they could compete, mammals evolved to a higher state. Without extinction events, perhaps we wouldn't be here today.Scientists estimate that there have been at least 5 mass extinctions in the last 540 million years. They also believe that we have entered a new extinction event. Species are becoming extinct at a much faster rate than before. Instead of asteroids or volcanic eruptions, the current event is the result of human activities. Human activities, for example, have 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 the habitats of many plants and animals. Cutting down forests and polluting rivers destroys the habitats of many forms of life.There is no longer any doubt that this is happening. Species of life are disappearing at an increasing rate. Global temperatures are rising and weather patterns are changing. Scientists are warning us that fast action isnecessary to save our future. If we don't act, we may go the way of the dinosaurs. (This new extinction event is caused by humans.)Level4 Unit2 1 VocabularyBody SystemsThe body's circulatory system includes the heart and blood vessels. The heart pumps blood to all parts of the body through a network of arteries and veins. (The blood vessels that carry oxygen-rich bloodfrom the heart are called arteries.)The digestive system breaks down and absorbs food into the body. It's supplies the energy that the body needs for growth and repair. After digestion, excess food is turned into waste and eliminated from the body. (The digestive system is where food is broken down and absorbed into the body.)The nervous system includes the brain,spinal cord and nerves. This is your body's control system. It controls your muscles and organs, including your circulatory and digestive system. (The nervous system regulates your heartbeat and digestion.)The respiratory system includes the nose and lungs. It brings air and oxygen into the body and removes carbon dioxide. The lungs are where oxygen enters the bloodstream, and carbon dioxide is removed.The immune system protects the body against infections and diseases. Sneezing and fever are examples of how the immune system works. If an infection invades the body, the immune system attacks it.Great DiscoveriesThe controlled use of fire allowed people to cook food and survive in the colder climates. Fire provided light so that people could work andsocialize for longer hours.With the invention of agriculture, people could grow food andsettle into communities. By growing food, people could spend less time hunting, and more time for other things such as art. (With the development of agriculture, people had more time for other activities.)The domestication of animals allowed people to raise and use animals for food and work. By raising herds of animals such as sheep, humans had a regular supply of meat and clothing. The strength of animals such as horses andoxen was used for work and transportation.The development of tools and machines has resulted in more efficient manufacturing and construction. With better tools and machines, work can be done with fewer people and at much lower costs. (The use of machines has reduced the number of people needed to make things.)The development of science and engineering has improved many things, including communications. With an understanding of electricity, telephones and radios allow people to communicate over long distances.

The piece of fruit is either an orange or an apple. We can’t see which it is because we can’t see inside the box. The probability th at it is an orange is equal to the probability that it is an apple. It may be an apple, and it may be an orange. It’s got 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 prob abilities are different. From his point of view, the probability that he has an orange is 100% or 0%. That’s because he knows what he has. For him there is no 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 your point of view.People see things from different points of view. This often leads to arguments between people. Here are some examples. From this man’s point of view, he is relaxing. He needs to relax because he has been working too hard. He hasn’t been getting enough sleep.His wife sees things differently. She isn’t aware of how hard he has been working. From her point of view, he is doing nothing. However, she knows what needs to be done around the house. It isn’t fair that she has to work while he does nothing.When people see things from different points of view, they often come to different conclusions. These differences can cause real communication problems.Level4 Unit2 Part2 VocabularyDisastersEarthquakes are caused by forces deep within the earth. When the earth shakes, buildings can collapse and people can be buried inside.An explosion is a rapid, violent release of energy. Explosions can be caused by chemical reaction, such as inside an engine. A spark can ignite a mixture of gases, and release energy for good or destructive purposes.Accidents are often caused by people doing foolish things or by not being careful. One major cause of accidents is driving too fast. Accidents with fire can be very serious and can result in very painful injuries.Epidemics are the rapid spread of a disease, such as the flu or Ebola. Throughout history epidemics have killed millions of people.Storms are caused by changes in the atmosphere resulting in high winds and heavy rain. Thunderstorms are caused by electric charges in the atmosphere that produce lightning, which can cause forest fires. Some storms cause flooding and major damage to homes and cities.ReligionsFollowers of the Islam religion are called Muslims. These Muslims are praying inside a mosque. Muslims are called to prayer 5 times a day, beginning just before sunrise.Christianity is based on the teachings of Jesus Christ who lived more than 2000 years ago. Christians believe that Jesus is the son of god. Christians often gather in churches or cathedrals to worship.Followers of Judaism are called Jews. These Jews are meeting inside a synagogue, which is a place of worship and study. Judaism was founded over 35 hundred years ago in the middle east. Judaism is based on the teachings of Moses, who they believe is the most important prophet.Buddhism began in India and is based on the teachings of the Buddha. The religion is about 25 hundred years old. Some Buddhists practice a form of meditation in which they empty their minds of any thought.Hinduism is the world’s third most popula r religion and is the main religion of India. Hinduism has no founder and is a mixture of many beliefs. Some Hindus believe in the cycle of birth, life, death and rebirth.Level4 Unit2 Part2 DialogueMissing AircraftDo you have any more information about the location of the missing aircraft?No, we don’t. The only information we have is that it disappeared.What about the last communication with the aircraft?The last communication was about 15 minutes before it disappeared.Was there anything unusual in the communication?No, there wasn't anything unusual.Nothing pointed to any kind of problem.Anyway, we are confident that we will find it.It’s a large aircraft so it shouldn’t be difficult to find.How many countries are helping with the search?Right now, we have search teams from 3 countries starting the search.It’s a big area to search, so can you give us an estimate about how long it will take?Yes, it’s a big area, so it might take a long time.But we won’t give up.We will search until we find it.Have they found the wreckage yet?What are you talking about?You know, the airplane that disappeared last year.Oh, yes, now I know what you are referring to.Yes, they found some piece of it.What about the black boxes?No, they still haven’t found the b lack boxes.It’s hard to believe they still don’t know what happened.Perhaps they’ll never know, especially if they don’t find the black boxes.Whatever happened to it, there is no good reason why a modern airline is allowed to disappear.I agree with you.懂你英语L4-Unit2 3Level4 Unit2 Part3 ListeningAlcatrazAlcatraz is a small island in San Francisco Bay, 1.5 miles from San Francisco. From Alcatraz, you can see the famous Golden Gate Bridge. Alcatraz is also famous and is now a major tourist attraction. Tourists can reach the island by boat from the city.Alcatraz has often appeared in movies, including "Escape from Alcatraz" which was made in 1979. One reason it’s famous is because it used to be a prison, a very special prison. It was designed for prison ers who were causing trouble in other prisons, such as trying to escape. It was a maximum security prison, so escape was almost impossible. The waters around it are cold, and only very strong swimmers can swim from the island to San Francisco.The first group of prisoners arrived in 1934. There were 137 prisoners, including bank robbers and murderers. They came by train from another prison in the state of Kansas. During that trip, there was heavy security. The prisoners were under guard and handcuffed. Nobody wanted them to escape.The prison was designed to hold up to 336 prisoners. However, the average population was only about 270. Although there were several notorious inmates, such as Al Capone, most of the inmates were not well-known. Many had tried to escape from other prisons or were considered violent. If a man did not behave at another prison, he could be sent to Alcatraz. At Alcatraz there was just one inmate in each prison cell.Prison life at Alcatraz was highly structured and boring. It was designed to teach prisoners to follow rules. They had four rights: food, clothing, shelter, and medical care. Everything else was a privilege that had to be earned. Privileges included working, visits from family members, and access to the prison library. There were also activities such as painting and music. Once a prisoner showed that he could follow the rules, he could be transferred back to another prison to finish his sentence.Alcatraz was used as a prison for 29 years. During that time, no prisoner escaped successfully. There were 14 escape attempts, involving 36 prisoners. Twenty-three were caught alive, and six were shot and killed. Two men tried to escape twice. Two drowned and five were listed as missing and presumed drowned. The most violent escape attempt occurred on May 2, 1946 when six prisoners tried to escape. That event is called the "Battle of Alcatraz."While it was in use, Alcatraz held some of the most notorious criminals in American history, such as Al Capone. Al Capone was a crime boss who built his career in Chicago. The prison was finally closed in 1963. It was closed because it was too expensive to operate.Level4 Unit2 Part2 VocabularyGraphs & chartsA bar graph uses rectangular bars of different lengths to show and compare data. The lengths of the bars are proportional to the values they represent. The bars can be vertical, up and down, or horizontal.A circle graph, often called a pie graph, is shaped like a circle. It is divided into segments that look like pieces of a pie. Percentages are used to compare the segments, which are ordered from biggest to smallest.Line graphs are used to show the relationship between two variables, such as time and distance. These variables are plotted on 2 axes, the X axis and the Y axis. The X axis often shows time, while the Y axis shows how quantities, such as distance, temperature, or profits change with time.A flowchart is a type of graph that shows how a process or a project flows from start to finish. A flow chart consists of start points, inputs, outputs and decision points.An organizational chart or org chart show the structure of a company. It shows how people and departments within a company are connected. It defines the roles and responsibilities of people and departments within a company.Legal TermsLaws are rules that people are supposed to follow. A system of laws governs the behavior of people within a country. (An action that is against the law is an illegal action.) (An action that follows the law is a legal action.)Criminals are people who break the law. People who commit a crime are called criminals. Some criminals are very dangerous and needed be put in jail. (Someone who commits a crime may be sent to prison.)A jail or prison is a place where criminals are locked behind bars, sometimes for many years. Prisons are designed to keep criminals away from other people.A courthouse is where someone charged with committing a crime goes on trial. In court, evidence is presented to show the guilt or innocence of a person on trial.When someone breaks the law, they may be arrested by the police. To arrest someone means to take and hold them until they go on trial.(When a person is charged with breaking a law ,they are tried in a court of law.)Level4 Unit2 Part3 DialogueCurrent ExchangeMay I help you, sir?I’d like to change some US dollars into Japanese yen, please.Yes, certainly sir.How much would you like to change?I’d like to change 500 dollars.May I see your passport please?I don’t have it with me, but I do have my driver’s lic ense.Would that be OK?No, I'm sorry, sir.I need to see your passport, it’s the law.Look, I’m not asking for a loan.I just want to convert my dollars into yen.Why do I need my passport?I understand your frustration sir, but that’s the law.I can not do something that is illegal.OK, do you have any suggestions?Sure, the easiest things for you to do is to use a machine in one of the hotels near here.You can borrow someone’s passport and then do the conversion.So the machine doesn’t check my fingerpr ints or anything like that?

流利说_懂你英语_Level4_UnitLevel4 Unit2 Part1 Listening - Extinction Events 1The Earth was formed about 4.6 billion years ago.The first life appeared about a billion years later.The first plants didn't appear until around 2 billion years ago.Until about 580 million years ago, life forms were small and microscopic. Since that time, life has evolved into many different types, or species. However, scientists estimate that more than 99% of them are now extinct.There have been several extinction events in the history of the Earth.In an extinction event many life forms, or species of life, die out.The causes of mass extinction events are unsolved mysteries.These events are not predictable and can happen at any time.Scientists think that some of them were started by asteroid impacts or volcanic eruptions.Events like these 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 all species on the planet died out. When the asteroid hit the earth, it started a chain of events.A chain of events is a series of events linked together, like a chain.This particular chain of events happened over a period ofmonths and years.When the asteroid hit the Earth, it caused a huge cloud of dust to enter the atmosphere.This cloud of dust blocked the sun and darkened the Earth for many months.Without enough sunlight, 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 have played an important part in the evolution of life.In fact, some extinction events have helped to accelerate evolution.For example, some mammals lived through the age of the dinosaurs, but they couldn't compete.When the dinosaurs were removed, the mammals were able to compete more successfully.Once they could compete, mammals evolved to a higher state.Without extinction events, perhaps we wouldn't be here today.Level4 Unit2 Part1 Listening - Extinction Events 2Scientists estimate that there have been at least 5 mass extinctions in the last 540 million years.They also believe that we have entered a new extinction event.Species are becoming extinct at a much faster rate than before.Instead of asteroids or volcanic eruptions, the current eventis the result of human activities.Human activities, for example, have 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 the habitats of many plants and animals. Cutting down forests and polluting rivers destroys the habitats of many forms of life.There is no longer any doubt that this is happeningSpecies of life 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.(This new extinction event is caused by humans.)Level4 Unit2 Part1 Vocabulary - Body SystemsThe body's circulatory system includes the heart and blood vessels.The heart pumps blood to all parts of the body through a network of arteries and veins.The digestive system breaks down and absorbs food into the body.It supplies the energy that the body needs for growth and repair.After digestion, excess food is turned into waste and eliminated from the body. The nervous system includes the brain, spinal cord and nerves.This is your body's control system.It controls your muscles and organs, including your circulatory and digestive systems.The respiratory system includes the nose and lungs.It brings air and oxygen into the body and removes carbon dioxide.The lungs are where oxygen enters the bloodstream and carbon dioxide is removed.The immune system protects the body against infections and diseases.Sneezing and fever are examples of how the immune system works.If an infection invades the body, the immune system attacks it.(The blood vessels that carry oxygen-rich blood from the heart are called arteries.)(The digestive system is where food is broken down and absorbed into the body.)(The nervous system regulates your heartbeat and digestion.) Level4 Unit2 Part1 Vocabulary - Great DiscoveriesThe controlled use of fire allowed people to cook food and survive in the colder climates.Fire provided light so that people could work and socialize for longer hours.With the invention of agriculture, people could grow food and settle into communities.By growing food, people could spend less time hunting and more time for other things such as art.The domestication of animals allowed people to raise and use animals for food and work.By raising herds of animals such as sheep, humans had a regular supply of meat and clothing.The strength of animals such as horses and oxen was used for work and transportation.The development of tools and machines has resulted in more efficient manufacturing and construction.With better tools and machines, work can be done with fewer people and at much lower costs.The development of science and engineering has improved many things, including communications.With an understanding of electricity, telephones and radios allow people to communicate over long distances.(Science and engineering have changed the way we communicate with each other.)(With the development of agriculture, people had more time for other activities.)(The use of machines has reduced the number of people needed to make things.)Level4 Unit2 Part1 Dialogue - Smartphone AddictionI took a vacation last night.What are you talking about?Where did you take your vacation?I didn't go anywhere.I just spent an evening without my smartphone.How was it?It was great.

Level3.Unit2 Part1作者：Ding MingListening: States of Matter物质状态Matter is made of atoms and molecules.Water, for example, is the H2O molecule.This means that a molecule of water has 3 atoms.这意味着水分子有3个原子。

A water molecule has two hydrogen atoms and one oxygen atom.Substances like sugar have many atoms in their molecules.A molecule of sugar has many atoms, including carbon, hydrogen and oxygen.------------------------------------------------------------------------------------------------------Matter is made of molecules, such as H2O, which is the water molecule.Matter can be one of three states, solid, liquid or gas.Water and ice are the same substance, but they are in different states.These states depend on the temperature of the molecules.When we heat a substance, the molecules move faster and try to take up more space. When we cool a substance, the molecules move more slowly.When we cool a substance to its freezing point, it becomes a solid.-------------------------------------------------------------------------------------------------------------In a solid, the molecules move very little.Their positions are almost fixed.To be fixed means that their positions don’t change.If we heat the molecules, they move faster and away from each other.The solid begins to melt, like ice cream on a hot day.-----------------------------------------------------------------------------------------------------------At a certain temperature, a solid begins to change into a liquid.The temperature at which a solid change into a liquid depends on the substance.For water, the solid begins to change into a liquid when its temperature rises to about 0 degree Celsius.For some substances, such as steel, the temperature at which it becomes a liquid is much higher.对于某些物质,如钢,它变成液体的温度要高得多。

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.

Some of his nerves had been damaged but there is achance that they will heal.The new drugs being developed might make it possible for the nervesto grow back. Still he has to face the possibility that nothing will work.If he wants to regain the use of his legs he’ll have to work hard.However happens Harry is determined to think positively.Even if he can’t walk he can still attend meetings all over the world.With new technology he would be anywhere and there is much of that he could still do.Luckily he still has the use of his arms and hands and his brain is still functioning.With the right attitude he can find a way forward.There is no reason for despair or feeling sorry for oneself.That kind of thinking won’t solve anything.He just hope that his company or another company will give him the chance toprove himself. He can still be a valuable asset for them, come with me.He has a positive attitude toward life and is determined to prove himself.现在一个月后，哈利仍然记不起发生了什么。
