1、Why Would They Falsely Confess?
Why on earth would an innocent person falsely confess to committing a crime? To most people, it just doesn't seem logical. But it is logical, say experts, if you understand what can happen in a police interrogation room.
Under the right conditions, people's minds are susceptible to influence, and the pressure put on suspects during police grilling is enormous. "It's a little like somebody's working on them with a dental drill," says Franklin Zimring, a law professor at the University of California at Berkeley. "The pressure is important to understand, because otherwise it's impossible to understand why someone would say he did something he didn't do. The answer is: to put an end to an uncomfortable situation that will continue until he does confess."
Developmental psychologist Allison Redlich recently conducted a laboratory study to determine how likely people are to confess to things they didn't do. In her experiment, participants were seated at computers and told not to hit the "alt" key, because doing so would crash the systems. The researchers then intentionally crashed the computers and accused the participants of hitting the "alt" key to see if they would sign a statement falsely taking responsibility.
Redlich's findings clearly demonstrate how easy it can be to get people to falsely confess: 59 percent of the young adults in the experiment immediately confessed. Redlich also found that the younger the participant, the more likely a false confession. Of the 15-to 16-year-olds, 72 percent signed confessions, as did 78 percent of the 12-to 13-year-olds.
"There's no question that young people are more at risk," says Saul Kassin, a psychology professor at Williams College, who has done similar studies with similar results, ______
Both Kassin and Redlich note that the entire "interrogation" in their experiments consisted of a simple accusation-not hours of aggressive questioning-and still, most participants falsely confessed.
Because of the stress of a police interrogation, they conclude, suspects can become convinced that falsely confessing is the easiest way out of a bad situation. "In some ways," says Kassin, "false confession becomes a rational decision."

2、Stress Lessen Course
Doreen Sykora is now a junior at McGill University. She had a difficult time when she first began college. She said, "I was always well prepared for my examinations. But I would go in to class to take the exam, and I would fall apart. I could not answer the questions correctly-even though I knew the answers! I would just blank out because of nervousness and fear". Histoshi Sakamoto, an anthropology student at Temple University in Tokyo reports similar experiences.
These two young students were experiencing something called test anxiety. Because when a student worries and is stressed about a test, his or her mind does not work as well as it usually does. The student cannot write or think clearly because of the severe tension and nervousness.
Now there are special university courses to help students. In these courses, advisors and psychologists try to help students by teaching them to manage test anxiety. Such a course helps students learn to live with stress and not fail because of it. First students take a practice test to measure their worry level. If the tests show that their stress level is high, the students can take a short course to manage the fear. These courses teach students how to relax their bodies. They get training to become calm in very tense situations. By controlling their nervousness, they can let their minds work more easily. Learned information then comes out without difficulty on a test.
Doreen Sykora saw immediate results after taking such a course. She now has enthusiasm about the relaxation methods. "Mostly, what I do is imagine myself in a very calm place. Then I imagine myself picking up a pencil. I move slowly and carefully. I breathe easily and let all the tension out. With each breath, more worry leaves me. It really works too. My grades have improved greatly! I'm really doing well at McGill now. This relaxation method works not only on examinations, but it has improved the rest of my life as well".
For Histoshi in Tokyo, the results were much the same. He is enjoying school a lot more and learning more.
These are signs of test anxiety EXCEPT____.
【单选题】

A.worries about a test

B.stressed about a test

C.low grades and poor study habits

D.nervousness during the test

正确答案:C

答案解析:第1段讲述了两个学生的详细情况，出于对考试的担心、压力、紧张，使得他们难以考好。如果是成绩不好、学习习惯不好，即便不紧张也是考不好的。因此C是答案。

3、Better Control of TB Seen if a Faster Cure is Found
The World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis. Most times, the infection remains inactive. But each year about eight million people develop active cases of TB, usually in their lungs. Two million people die of it. The disease has increased with the spread of AIDS and drug-resistant forms of tuberculosis.
Current treatments take at least six months. Patients have to take a combination of several antibiotic drugs daily. But many people stop as soon as they feel better. Doing that can lead to an infection that resists treatment. Public health experts agree that a faster-acting cure for tuberculosis would be more effective. Now a study estimates just how effective it might be. A professor of international health at Harvard University led the study. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean fewer infectious patients who can pass on their infection to others.
The researchers developed a mathematical model to examine the effects of a two-month treatment plan. They ______ the model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. And it might prevent about twenty-five percent of TB deaths. The model shows that these reductions would take place between two thousand twelve and two thousand thirty. That is, if a faster cure is developed and in wide use by two thousand twelve.
The World Health Organization developed the DOTS program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make sure they continue treatment.
Earlier this year, an international partnership of organizations announced a plan to expand the DOTS program. The ten-year plan also aims to finance research into new TB drugs. The four most common drugs used now are more than forty years old. The Global Alliance for TB Drug Development says its long-term goal is a treatment that could work in as few as ten doses.
【单选题】

A.provided

B.introduced

C.tested

D.tempted

正确答案:C

答案解析:只有填C（检验）才能符合上下文意思，其他3项不仅词义不合适，词的用法也不对。

4、Walking to Exercise the Brain
Do you think sitting and studying all the time will improve students grades? Think again. Getting some exercise may help, too.
New research with older people suggests that taking regular walks helps them pay attention better than if they didn't exercise.
Previous research had shown that mice learn, remember and pay attention better after a few weeks of working out on a running wheel. Mice that exercise have greater blood flow to the brain than those who don't. Their brain cells also make more connections.
Neuroscientists (神经科学家) from the University of Illinois at Urbana Champaign wanted to find out if the same thing is true for people. First, they measured the physical fitness of 41 adults, ages 58 to 77, after each person walked I mile. Then, participants looked at arrows on a computer screen and had to use computer keys to show which way one particular arrow was pointing.
Adults who were physically fit were faster at the arrow task, and their answers were just as accurate as their less - fit peers, the researchers found. The fitter participants also had more blood flow to a part of their brain responsible for paying attention and making decisions.
In a second study, 15 elderly people who completed a 6 - month aerobic - training (有氧运动) course were faster at attention tasks compared with 14 seniors who just did stretching and toning (韵律操) exercises for the same amount of time.
So, even going for a walk every 2 or 3 days for just 10 to 45 minutes can help. That should be good news for the elderly.
The effects of exercising on the brains of younger people haven't been studied yet. Still, it can't hurt to take occasional breaks and go for a walk or run around with friends. Whatever you do, though, don't try to read and walk at the same time. You could end up hurting yourself!
It can be good for health when one takes a walk every 2 or 3 days for at least ______.【单选题】

A.3 minutes

B.45 minutes

C.30 minutes

D.10 minutes

正确答案:D

答案解析:本题有一定难度，需要认真阅读文章。答案依据在文章第七段。带着题干信息词回到文章定位。第七段第一句谈到，每两三天出去散步10到45分钟会对健康有益，回来看选项，很明显，D是近义解释，是答案。

5、Shopping at Second - hand Clothing Stores
When 33 year old Pete Barth was in college, shopping at second hand clothing stores was just something he did- "like changing the tires on his car." He looked at his budget and decided he could save a lot of money by shopping for clothes at thrift shops.
"Even new clothes are fairly disposable (用后即丢掉的) and wear out after a couple of years," Barth said. "In thrift shops, you can find some great stuff whose quality is better than new clothes."
Since then, Barth, who works at a Goodwill thrift shop in the US state of Florida, has found that there are all kinds of reasons for shopping for second - hand clothing. Some people, like him, shop to save money. Some shop for a crazy - looking shirt. And some shop as a mean conserving energy and helping the environment.
Pat Akins, an accountant at a Florida Salvation Army (SA) (救世军) thrift shop, said that, for her, shopping at thrift shops is a way to help the environment.
"When my daughter was little, we looked at it as recycling," Akins said. "Also, why pay 30 dollars for a new coat when you can get another one for a lot less?"
Akins said that the SA has shops all over the US- "some as big as department stores. All of the clothes are donated (捐赠), and when they have a surplus (盈余), they'll have" stuff a bag" specials, where customers can fill a grocery sack with clothes for only 5 or 10 dollars.
Julia Slocum, 22, points out, however, that the huge amount of second - hand clothing in the US is the result of American wastefulness.
"I'd say that second - hand stores are the result of our wasteful, materialistic culture," said Slocum, who works for a pro - conservation organization, the center of a New American Dream. "Thrift shops prevent that waste from going to landfills (垃圾填埋场). They give clothing a second life, provide cheaper clothing for those who can't afford to buy new ones and generate (创造) income for charities. They also provide a way for the wealthy and middle classes to shed (摆脱) the guilt for their level of consumption.
Thrift shops can do everything EXCEPT ______.
【单选题】

A.give clothing a second life

B.generate income for charities

C.provide cheaper clothes for the poor

D.stop rich people from wasting money

正确答案:D

答案解析:本题有一定难度，需要认真阅读文章，答案依据在文章最后一段。最后一段谈到，旧货店给了服装二次生命，给那些买不起新衣服的人提供便宜衣服，还把一些收入捐给慈善机构，但没有提到阻止富人浪费钱，所以答案是D。

6、The Hurricane
1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, and the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds and storm surges(风暴潮). The storm surges and heavy rains can lead to flooding.
2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, or the Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia and in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).
3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding and huge waves crashing on to the shore. During a hurricane, homes, businesses and public buildings may be damaged or destroyed, roads and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harbor if they do not receive adequate warning.
4. If a hurricane is comming in your area, the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from windows and glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.
Paragraph 1 ______
【单选题】

A.Where do hurricanes usually happen?

B.What damages can a hurricane cause?

C.What should you do during a hurricane?

D.What is a hurricane?

E.What are different names of hurricanes?

F.How do you know a hurricane is coming?

正确答案:D

答案解析:本题有一定难度，段落主旨句不明显，需要通读文章第一段。通读文章第一段可以发现，第一段主要对飓风下了定义，对飓风概念进行了解释，回来看选项，D项简单概括了第一段的主要意思，是答案。

7、The Book of Life
So far, scientists have named about 1.6 million living species, and that's a just a fraction of that probably exists on Earth. With so many plants, animals and other creatures coveting the planet, it can be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.
A soon - to - be - started Web site might help. An international team of researchers has announced the creation of Web - based Encyclopedia of life( EOL). The project aims to catalog every species on Earth in a single, easy - to - use reference guide.
To get the encyclopedia started, the creators will use information from scientific databases that already exist. And eventually, in special sections of the site, nonscientist with specialized knowledge will get to join in. Bird - watchers, for example, will be able to input which bird they've seen and where. The technology for this kind of tool has only become available.
As the EOL develops, you might find it useful for school projects. The site will feature special pages for kids who are studying ecosystems (生态系统) in their neighborhoods. To make sure the encyclopedia is accurate, scientists will review much of the information added to it. People who visit the site will be able to choose to leave out pages that haven't been reviewed.
Another convenient feature of the EOL is that you'll be able to pick the level of detail you want to see to match your interest, age and knowledge. If you wanted to learn about bears for a science class report, for example, you could use the "novice" setting to get basic information about the animals. On the "expert" setting, on the other hand, you could get much more detailed information about the history, literature and exploration of bears.
It now takes years for scientist to collect all the data they need to describe and analyze species. The creator of the Encyclopedia of Life hope that their new tool will speed up that process.
"Spider" and "bird" mentioned in Paragraph 1 are examples to illustrate ______.【单选题】

A.there are numerous living species on Earth

B.animals are people's friends

C.it is easy to see spiders and birds

D.here are many types of spiders and birds

正确答案:A

答案解析:本题有一定难度，带着题干信息词回文章定位，答案依据主要在文章第一段：So far, scientists have named about l.6 million living species, ...it can be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.谈到了地球物种数量巨大，回来看选项，A项和原文句意相近，是答案。

8、Cell Phones
1. Believe it or not, cell phones have been around for over a quarter of a century. The first commercial cell phone system was developed by the Japanese in 1979, but cell phones have changed a lot since that time. The early cell phones were big and heavy but they have developed into small and light palm sized models. There are huge developments in their functions, too. We have had call forwarding, text messaging, answering services and hands - free use for years, but now there are new facilities, such as instant access to the Internet and receiving and sending photos.
2. Cell phones have become very common in our lives. Recent statistics suggest one in three people on the planet now have cell phone, and most of them say they couldn't live without one, Cell phones are used in every area of our lives and have become a necessary tool, used for essential arrangements, social contact and business. It easier to call for help on the highway. It possible to keep in touch with people "on the move" when people are traveling.
3. Cell phones have made communication easier and have reduced the need for family arguments f We can use cell phones to let our family know we'll be late or if there's a sudden change of plan or an emergency. Cell phones have eased the worries of millions of parents when their teenagers are out late. They can now contact their children at any time.
4. This does not mean that cell phones are all good news. Cell phones have brought with them a number of new headaches for their owners. It costs a lot to replace stolen phones, It is becoming a frequent occurrence, and have you ever seen such a huge phone bills? More serious, however, Cell phones bring the potential health problem. There are fears that radiation from the phones may cause brain tumor(肿瘤). This may be a time bomb waiting to happen to younger people who have grown up with cell phones. They simply can't live without cell phones!
Cell phones are common in our lives and have become ______.
【单选题】

A.a necessity

B.an emergency

C.a number of new headaches

D.family arguments

E.big and light palm - sized models

F.countless new facilities

正确答案:A

答案解析:本题难度不大，虽然答案依据不太明显，但第二段的主旨句可以看做是答案依据，通读第二段，可以判断出手机已成一个必需的工具，所以答案是A。

9、Arctic Melt
Earth's North and South Poles are famous for being cold and icy. Last year, however, the amount of ice in the Arctic Ocean (北冰群) fell to a record low.
Normally, ice builds in Arctic waters around the North Pole each winter and shrinks(缩小) during the summer. But for many years, the amount of ice left by the end of summer has been declining.
Since 1979, each decade has seen an 11.4 percent drop in end of summer ice cover. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner.
Last summer, Arctic sea ice reached its thinnest levels. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That's 38 percent less area than the average cover at that time of year. And it's a very large 23 percent below the previous record low, which was set just 2 years ago. This continuing trend has made scientists concerned to.
There may be several reasons for the ice melt, says Jinlun Zhang, an oceanographer (海洋学家)at the University of Washington in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice and open water.
Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water and the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.57 Celsius warmer than the average and 1.5c warmer than the previous record.
With both air and water getting warmer, the ice is melting from both above and below. In some parts of the Beaufort Sea, north of Alaska and western Canada, ice that measured 3.3 meters thick at the beginning of the summer was measured just 50 cm by season's end
The new measurements suggest that melting is far more severe than the thinking of scientists. Some scientists fear that the Arctic is stuck in a warming trend.
It can be learned from the last sentence that ______.
【单选题】

A.the ice melt in the Arctic may never stop

B.scientists are trying hard to stop the ice melt in the Arctic

C.scientists are delighted to find out what is going on in the Arctic

D.the warming trend in the Arctic can be reversed in the near future

正确答案:A

答案解析:本题难度不大，最后一句话的句意不难理解。文章最后一句谈到，科学家们担心北极处于变暖趋势，而且不能挽回，答案是B。

10、Sharing Silence
Deaf teenagers Orlando Chavez and German Resendiz have been friends since kindergarten (幼儿园). Together the two boys, who go to Escondido High School in California, have had the difficult job of learning in schools where the majority of the students can speak and hear.
Orlando lost his hearing at the age of one. German was born deaf, and his parents moved from Mexico to find a school where he could learn sign language. He met Orlando on their first day of kinder garten.
"We were in a special class with about 25 other deaf kids," German remembered. "Before then, I didn't know I was deaf and I was different."
"Being young and deaf in regular classes was very hard," signs Orlando. "The other kids didn't understand us and we didn't understand them. But we've all grown up together, and today, I'm popular because I'm deaf. Kids try to communicate with me."
Some things are very difficult for the two boys. "We can't talk on the phone, so if we need help, we can't call an emergency service," German signs. "And we can't order food in a drive - thru."
Despite of their difficulties, the two boys have found work putting food in bags at a local supermarket.
They got their jobs through a "workability" program, designed for teenagers from local schools with different types of learning disabilities.
German has worked in the supermarket since August, and Orlando started in November.
"The other people who work here nave been very nice to us," Orlando signs. "They even sign sometimes. At first, we were nervous, but we've learned a lot and we're getting better."
The opportunity to earn money has been exciting, both boys said. After high school, they hope to attend the National Technical Institute for the Deaf in New York.
Both Orlando and German have found their jobs at ______.【单选题】

A.a fast - food restaurant

B.a supermarket

C.a technical institute

D.a local school
