Do you have a hobby that helps you relax and unwind? For some people, there is no better way to relieve pressure than spending time in the garden. This small private area of green space can be their place of calm.__67__. A survey conducted by the Royal Horticultural Society, found that 82% of people in the UK said that gardening makes them happier. It also found that 70% of them, given the choice, would prefer to spend their working day in the garden with just 9% opting for an office.For those with green fingers, the pleasure of gardening comes from getting out in the fresh air, in all weathers and communing with nature -- even if there are a few too many worms! It can also be seen as a sort of digital-detox -- time away from technology. __68__.Dr Christopher Lowry, a neuroscientist at the University of Colorado, injected a bacterium commonly found in soil into mice to see what affection this would have on them. __69__. When we dig in soil we absorb this bacterium through our lungs or cuts in our skin, so Dr Lowry concluded that since the mice seemed happier when treated with soil bacteria, it’s likely we would be, too.__70__. There’s evidence that recovering alcoholics who have been given the opportunity to plant, grow, and even sell their produce, have managed to stop their addictive habits. Scot Stephenson, for example, got dismissed from school and started a vocational qualification in gardening. He says, “I got my NVQ level 2 which is my first qualification and enjoyed it ever since.”Whatever the reason, there are many therapeutic benefits to getting your hands dirty, doing some physical hard work and then watching your garden grow. Does this sound like your idea of fun?67-70: DFACWould You B ully(欺负) a Driverless Car or Show It Respect?Say you’re driving down a two-way street and there’s a truck unloading a delivery in the opposite lane. The oncoming traffic needs to pull out into your lane to overtake.What do you do?___67___ Eventually one of us feels charitable and slows down to allow the oncoming car to overtake and give permission with a quick flash of headlights or a wave of the hand.But what if the car waiting patiently behind the parked truck is a driverless or autonomous vehicle (AV)? Will this robot car be able to understand what you mean when you flash your lights or wave your hands?Its sensors could decide that it’s only safe to overtake when there’s no oncoming traffic at all. On a busy road at school home time, this may be never, leading to increasingly angry drivers queuing behind. ___68___ This is one of the conclusions to be drawn from research carried out by Dr Chris Tennant of the psychological and behavioural science department at the London School of Economics.His Europe-wide survey finds that nearly two-thirds of drivers think machines won’t have enough common sense to interact with human drivers, and more than two-fifths think a robot car would remain stuck behind ourassumedparked truck for a long time.Driving isn’t just about technology and engineering, it’s about human interactions and psychology. The road is a social space. ___69___ “If you view the road as a social space, you willconsciously negotiate your journey with other drivers. People who like that negotiation process appear to feel less comfortabl e engaging with AVs than with human drivers,” says Mr Tennant in his report.___70___ A statistic often trotted out(动不动就搬出) is that human error is responsible for more than 90% of accidents, with our tendency to road anger, tiredness and lack of concentration. 67-70 AFBETen years ago, after 2 years as a postdoc (博士后), I found myself wondering whether I should take a different road. Up to that point, I had stuck to a pretty traditional path investigating cancer genetics, but I was losing interest in the research. At the same time, federal funding had flattened, which added to my dissatisfaction. ___67___ Then came the hard part: identifying a new career that would nurture my passion for science and allow me to make an impact with my work.As I was considering my options, I found inspiration in my first graduate school research tutor, whose work r eminded me that scientists’ efforts away from the bench can be incredibly powerful. But I still didn’t know exactly what I should do. ___68___ A colleague mentioned that a professor at a nearby 2-year college was training students to produce monoclonal antibodies for labs on campus. I was impressed that the professor had taken on this type of ambitious project with relatively inexperienced students. Curious to find out more, I set up a meeting with John and was struck by his sincerity and the way he prioritized student training above grants, publications, and personal ambition. I could also see his passion for teaching, which reminded me of the dreamto become a high school biology teacher.__69___ I found a faculty position and joined John at the same quiet junior college. Now, I effectively hold two positions: classroom instructor and research co-adviser of 15 inexperienced but eager undergraduates. Both roles give me a chance to help students transform themselves, which is enormously rewarding.___70___ It’s discouraging when others see both my students and me as less worthy because we are not at universities. We sometimes struggle to get access to federal funding, scientific conferences, and other resources and opportunities. My pay is below the standard at 4-year research institutions, even though my teaching workload is greater. But my occasional frustration is relieved by the thought of the students, who I have helped train.Looking back at these 10 years, I realize how much my work on this campus has helped me grow, both as an academic and a tutor. I’m grateful that I stepped away from a traditional career path and found a way to serve both the student and research communities in my own way, modest though it may be.67—70 EBFAZoos have existed since ancient times and were features of the great courts of Egypt and China. The display of unusual animals form foreign countries was, for a long time, a show of wealth and power. Today, zoos focus on the preservation of animals species and the education ofthe public. __67___Some animals are distinctly unsuited for life in a zoo, however noble the aims of the organization. Keeping elephant in captivity (囚禁) has long caused argument among animals rights activists. Elephant in the wild wander constantly, covering a wide territory on a daily basis. In captivity, they have no choice but to stand still for long periods of time. ___68____. Yet elephants are a threatened species in their native environments and are heavily caught for ivory(象牙)，leather and meat illegally. To protect the species form the wild due to injury or abandonment.___69___. The chances are, if a zoo has nothing but cement floors and metal enclosures, the animals will not do as well. Many famous zoos now construct enclosures allowing animals freedom of movement and native vegetation. Some zoos have even begun housing species of animals together that normally interact in the wild, such as certain types of monkeys.Zoos are not a perfect solution for preservation.____70___. They are undeniably helpful in repopulating declining animal species and encouraging a preservationist outlook, but they are unquestionably primary in their treatment of some animals. Hopefully, animal activists and zoo advocates will continue to work together, finding ways to create the best environment for captive animals in breeding and repopulation efforts.67-70 CEDAA few years ago, a Finnish app took the mobile gaming world by storm. Its set-up was simpleand its idea illogical: Angry Birds was little more than a shooting game, with birds instead of bullets and green pigs in place of targets. 67 Shortly after Angry Birds took off, audiences found a new distraction in Fruit Ninja, a game where the object was to chop falling produce. Then there was Candy Crush, where players could save a candy kingdom by matching like-colored bonbons.68 That was their charm, after all: They were knowingly ridiculous or illogical, an attack into mindless amusement. In games like Angry Birds, players found an escape from reality. All they had to do is resign themselves to the logic of the game, a world of simple cause-and-effect: Slingshot a bird, kill a pig, score points.Fast forward to 2016, and there's now an Angry Birds movie, here to fill you in on all the details you never wished to know. The birds have been given personalities, motives and back-stories, and so have the evil green pigs. Meanwhile, the game's nonsense had to be made sense of due to a necessary plot for a movie. Logic replaced illogic. Angry Birds is not alone in having its gray areas sketched in for the big screen. Hollywood has made an industry of answering the questions no one ever thought to ask; to the point of even giving a brand of toy blocks its own story in 2014’s The Lego Movie. Countless secondary characters have also been pulled from the sidelines and given their own opportunities to show on the screen. That includes the forgetful blue fish Dory from 2003’s Finding Nemo. 69 Viewers no longer have the luxury of imagining back-stories for their favorite characters, or debating the open-ended questions in a film’s source materials: An endless flow of prequels(前传), sequels(续传) and spin-offs(衍生产品) fill in those blanks for them.70 They'll know. Everything will be determined for them: According to the movie, the main bird Red gets picked on for his bushy eyebrows, and that leaves him feeling isolated and, well, angry. In some ways, Hollywood has taken on the role of fan fiction writers, by expanding and exploring every corner of its fictional universes. But when these universes expand too widely, what will be left to imagine?67-70：CE FAIn so many ways, cyberspace(网络空间) mirrors the real world. People ask for information, play games, and share hobby tips. Others buy and sell products. Still others look for friendship, or even love.Unlike the real world, however, your knowledge about a person is limited to words on a computer screen. Identity and appearance mean very little in cyberspace. ____67____ So even the shyest person can become a chat-room star.Usually, this "faceless" communication doesn't create problems. Identity doesn't really matter when you’re in a chat room discussing politics or hobbies. In fact, this emphasis on the idea themselves makes the Internet a great place for exciting conversation. Where else can so many people come together to chat about their interests?____68____ They are looking for serious love relationships. Is cyberspace a good place to find love? That answer depends on whom you ask. Some of these relationships actually succeed. Others fail miserably.Supporters of online relationships claim that the Internet allows couples to get to know each other intellectually first. Personal appearance doesn't get in the way.But critics of online relationships argue that no one can truly know another person in cyberspace. Why? Because the Internet gives users a lot of control over how others view them. Internet users can carefully craft their words to fit whatever image they want to give. And they don't have to worry about what their “faceless” communication is doing for their image. ____69____All of this may be fine if the relationship stays in cyberspace. But not knowing a person is a big problem in a love relationship. ____70____ This inevitably leads to disappointment when couples meet in person. How someone imagines an online friend is often quite different from thereal person.So, before looking for love in cyberspace, remember the advice of Internet pioneer Clifford Stoll: "Life in the real world is far richer than anything you'll find on a computer screen67-70 BFACNo matter how early she went to bed, Maggie couldn't fall asleep until the early hours. Though constantly exhausted, Maggie got good grades in school, but she often got in trouble for napping during her morning classes.After graduating from college, Maggie realized her dream of becoming a teacher. However, waking up for her 8:30 a.m. classes turned her into a zombie (无生气的人) , and she lost her job because she lacked enthusiasm.Maggie isn’t lazy. She suffers from delayed sleep phase syndrome (DSPS，睡眠相位后移症候群)----a disorder that affects one in 750 adults that causes them to be somewhat nocturnal （夜间活动的）. DSPS is often confused with insomnia(失眠），perhaps because sufferers seem tired duringthe day. However, the two disorders are very different. Insomniacs have trouble with the process offalling asleep.67They just can’t fall asleep early even if they want to.Essentially, DSPS means a person's internal clock is set differently. ____ 68 _______ A s aresult,they're out of sync(同步）with the rest of society. People with DSPS struggle to keep their eyes open during morning meetings because their bodies are convinced it*s the middle of the night. They seem less efficient and creative at the office, and make more workplace accidents. DSPS also damages their health, causing depression, anxiety, heart disease and many other illnesses due to sleep deprivation.______69_______ . Fortunately, that’s not the case. Flexible work schedules are already verycommon. Traditionally, managers tend to think more people in the office equals more output, but new research shows that people who work flexible hours are more productive and more likely to stay with their company because they are happier and healthier. Thanks to these findings, many European countries have passed laws giving every worker the right to apply for a flexible work arrangement. According to Cary Cooper, a psychologist at Lancaster University, most U.K. employees will be working half from home in five years.This is great news not just for DSPS sufferers but also for their companies. 70 Consequently, they will be able to save a large sum of money.KEYS: FACDHow to Keep Your Digital Memorials Safe?Do you value your digital stuff? Nearly everyone is creating things with computers, and some do it without any concern for its value. Others recognize its current value, but think little about what it could mean to them in the future, and either aren't aware or don't think that all of it could bedestroyed tomorrow. But hard drives die all the time, and the online services into which people sink their time close with alarming regularity, taking the work of millions of people withit._________67____________.Steps1.Prepare to make a quick backup. If nothing else, get a cheap USB stick anddrag-and-drop your documents folder onto it. Worry about the other things later.You should do more than this, but it's most important to take the most valuable,irreplaceable information from your hard drive and put it on a second medium to guardagainst hard drive failure, theft or loss.2.Decide what you value. Some questions to ask yourself are:How replaceable is this data?How good are you at assessing the value of items? _______68__________. For things likebusiness accounts and documents, the answer is of course you would. This kind of thingshould be your first priority.3.Start making backups.__________69__________Diminishing returns(效益递减) apply in backups as they do with everything else. The cheapest and simplest backup methods take care of an overwhelming majority of likely loss-of-stuff. Over-complicating your backup strategy is the biggest trap: the more complicated and expensive you insist on making it, the less likely you are to do it.4.____________70______________If one of your backup drives fails, replace it immediately. Remember that all storage devices eventually become obsolete (陈旧的). If you have valuable files on obsolete media, those files become increasingly difficult to access with every passing year. So in order to keep your files accessible, remember to migrate your collection to new storage media periodically.67-70 FDEATutoring a New NormalIt’s not piano lessons or dance lessons. Nowadays, the biggest extra-curricular activity in the West is going to a tutor. “I spend about 800 Canadian dollars a month on tutors. It’s costly,” says Pet, a mother in Canada. However, she adds, “after finding out half my daughter’s class had tutors, I felt like my child was going to fall behind because everyone else seemed to be ahead.Shelley, a mother of three, also has tutors constantly coming in and out of her home. “When I used to sit down with my children, it was hard to get them focused. I was always shouting. When I got a tutor once a week, they became focused for one entire hour and could get most of their homework done.”Tutoring isn’t simply a private school phenomenon. 67________ In Cana da alone, seven percent of high school students reported using a tutor in 2010. That increased to 15 percent last year.Overall, parents hire tutors because they are worried schools are not meeting their expectations, but there is also a cultural shift. 68 ________As a large number of Asians emigrated to the West over the recent years, their attitudes towards education have had an impact.69________ “A lot of parents just don’t have time to help their children with homework,” says Julie Diamond, presi dent of an American tutoring company. “Others couldn’t help their children after Grade 3.”There has been a shift in the attitudes, too. “Children used to get bullied(欺侮）for having a tutor,” Diamond says. “Now it’s becoming the norm to have one.”70 ________One parent feels surprised that so many of her child’s classmates have tutors. “For the amount we pay in tuition, they should have as much extra help as they need，” she says. Still, she’s now thinking of getting a tutor. Why? Her daughter has actua lly asked for one.FADBIn 2009, the number of hungry people in the world reached one billion for the first time. It's difficult not to be shocked by the fact that more than one in seven people in the world do not have enough to eat. __67__ Hunger kills more people per year than diseases such as AIDS, malaria (症疾）and TB(肺结核）combined.The UN estimates that almost two thirds of the world's hungry people are in Asia, which is of course the world's most populous continent. __68__ Although this region has a much lower population than Asia, it has the highest percentage of hungry people. Almost all of the rest are in Latin America, North Africa and the Caribbean. In the richest regions of the world there are only a tiny number of people who don't have enough to eat.__69__ They include wars, droughts, floods, and the over-use of farming land. All these factors affect food production. Many people also blame greedy businessmen for pushing up the prices of basic foods in the global market. But the most important reason, quite simply, is poverty, which has increased recently due to the financial crisis of 2008.Although many people make the obvious point that there would be less hunger if the global population were smaller, few people would argue that there is not enough food to go around. The basic problem seems to be not a lack of food, but its distribution. In the last 50 years, global food production has risen even more quickly than the global population. There are many areas of the world in which people generally have more than enough food. __70__ The answer to world hunger,therefore, may be a balanced food distribution around the whole world. Everyone will have enough to eat, but not overeat.67-70 FABDFor centuries, people have wondered about the strange things that they dream about. Some psychologists say that this nighttime activity of the mind has no special meaning. Others, however, think that dreams are an important part of our lives. In fact, many experts believe that dreams can tell us about a person's mind and emotions.Before modern times, many people thought that dreams contained messages from God. It was only in the twentieth century that people started to study dreams in a scientific way.The Austrian psychologist, Sigmund Freud, was probably the first person to study dreams scientifically. In his famous book, The interpretation of Dreams (1900), Freud wrote that dreams are an expression of a person's wishes. He believed that (67) ___________The Swiss psychiatrist Carl Jung was once a student of Freud's. Jung, however, had a different idea about dreams. Jung believed that the purpose of a dream was to communicate a message to the dreamer. (68) ___________ For example, people who dream about falling may learn that they have too high an opinion of themselves. On the other hand, people who dream about being heroes may learn that they think too little of themselves.Modern-day psychologists continue to develop theories about dreams. For example, psychologist William Domhoff from the University of California, Santa Cruz, believes that dreams are tightly linked to a person's daily life, thoughts, and behavior. (69) ___________Domhoff believes that there is a connection between dreams and age. His research shows that children do not dream as much as adults. According to Domhoff, dreaming is a mental skill that needs time to develop.He has also found a link between dreams and gender. His studies show that the dreams of men and women are different. For example, the people in men's dreams are often other men, and the dreams often involve fighting. This is not true of women's dreams. Domhoff found this gender difference in the dreams of people from 11 cultures around the world, including both modern and traditional ones.Can dreams help us understand ourselves? Psychologists continue to try to answer this question in different ways. (70) ___________ The dream may have meaning, but it does not mean that some terrible event will actually take place. It's important to remember that the world of dreams is not the real world.67-70 EFCDIt is found that American students spend less than 15% of their time in school. 67 _____. A study published earlier this month by researchers at North Carolina State University, for example, finds that parental involvement -- checking homework, attending school meetings and events, discussing school activities at home -- has a more powerful influence on students, academic performance than anything about the school the students attend. Another study, published in the Review of Economics and Statistics, reports that the effort put forth by parents reading stories aloud, is devoted by either teachers or the students themselves. And a third study concludes that schools would have to increase their spending by more than $1,000 per pupil in order to achieve the same results that are gained with parental involvement.68 ______. But it is also revealed in researches that parents, of all backgrounds, don’t need to buy expensive educational toys or digital devices for their kids in order to give them an advantage. They don’t need to drive their offspring to enrichment classes or test-preparation courses. What they need to do with their children is much simpler: talk.But not just any talk. 69 _______. For example, a study conducted by researchers at the UCLA School of Public Health and published in the journal Pediatrics founds that two-way adult-child conversations were six times as powerful in promoting language development as the ones in which the adult did all the talking. Engaging in this reciprocal (双向的) back-and-forth gives children a chance to try out language for themselves, and also gives them the sense that their thought and opinions matter.The content of parents’ conversations with kids matters, too. Children who hear tal k about counting and numbers at home start school with much more extensive mathematical knowledge, report researchers from the University of Chicago. While the conversations parents have with their children change as kids grow older, the effect of these exchanges on academic achievement remains strong. Research finds that parents play an important role in what is called “academicsocialization” -- setting expectations and making connections between current behavior and future goals. 70 _______.67----70 DACBWhere do you think the world's happiest people live? Somewhere hot with sandy beaches? A country with a tradition of the fine food and culture? Not according to a recent study by the university of Leicester. Who are the happiest people on Earth? 67 Surprised? Well you’ll be more surprised when you hear that the Danes pay some some of the highest taxes in the world. So what is the secret of their success?Let's start with all that tax they pay. The Danish government provides its people with one of the finest education and health systems in the world. It spends more on children and elderly people per capital than other country.And there's another advantage to those high taxes. Because a shop assistant's final salary is not that much less than someone who works in a bank, for example, Danes don't choose their careers based on money or status as people in other countries do. They choose the job they want to do. There's a philosophy in Denmark known as "Jante-love", which translates as "you're no better than anybody else." ___68___ But workers in otherr countries are not used to looking at life in this way.Money doesn't seem as important in Denmark. It has been called a "post consumerist" society. ___69___ What is more important is the sense of society and it's no surprise that Danes are very used to socializing. 92% of Danes belong to some kind of social club and these clubs are evenpaid for by the government.___70___ They also show an amazing amount of trust in each other and their government. You can see sighs of this all over the country. You'll find vegetable stalls with no assistant. You take what you want and leave the money in a basket. Perhaps the bike is a good symbol for Denmark. The Danes can afford cars but they choose bikes---simple, economical, non-polluting machines that show no status and help keep people fit.67----70 EBFCWhy should mankind explore space? Perhaps the best answer lies in our genetic makeup as human beings. What prompted our distant ancestors to move from the trees into the plains, and on into all possible areas and environments? _____67_____. The wider the distribution of a species, the better its chance of survival.Exploration also allows minerals and other potential resources to be located. Additional resources are always beneficial when used wisely, and can increase our chances of survival. Knowledge or techniques acquired through exploration, or preparing to explore, filter from the developers into society at large. _____68_____. Also, we have already benefited from other by-products, including improvements in earthquake prediction —which has saved many lives —in satellites used for weather forecasting and in communications systems. Even non-stick saucepans and mirrored sunglasses are by-products of technological developments in the spaceindustry!_____69_____. The chances of a large comet (彗星) hitting the Earth are small, but it could happen in time. Such strikes in the past may account for the extinction of dinosaurs and other species. Human technology is reaching the point where it might be able to detect the possibility of this happening, and enable us to minimize the damage, or prevent it completely, allowing us as a species to avoid extinction.In certain circumstances, life on Earth may become impossible: over-population or wide spread diseases, for instance, might eventually force us to find other places to live. While the earth is the only planet known to sustain life, surely the adaptive ability of humans would allow us to inhabit other planets and moons. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future. _____70_____.. keys:67-70 DAFB。
