2. Passage Three Have you always dreamed of traveling to cool places， meeting lots of different people， and maybe picking up a language or two? No matter what country you live in， you can fly over the world’s highest waterfalls in Venezuela， learn world trade in Japan， study art in France， or take dancing lessons in Ghana. How? Join a study abroad program， where high school and college students live with a host family in a foreign country. Semester， summer， and year-long programs allow you to attend school， take intensive language courses， or perform community service in another country. Besides the excitement of travel， one reason to study abroad is that you will experience new customs， holidays， foods， art， music， and politics firsthand. “I learned the language and am now fluent， but perhaps more important was how much I learned about cultures， people， and myself. I learned this from the viewpoint of an active member of the community and my host family， not from the tourist’s point of view，” says Andrew， who studied in Poitiers， France. Another reason for studying abroad is that you’ll gain self-confidence. Christina studied in Caracas， Venezuela， a city of 10 million people and a huge change from her hometown of 35，000! Christina says she learned how to better stand up for herself and her beliefs and to express herself in another language. What could make you more confident than that? Living away from home can also help you adjust in the transition to college and adulthood. Matthew says he returned from studying in Australia with confidence， social savvy， and a genuine interest in international affairs that really set him apart from his peers. “After having gone abroad in high school， I found the transition to college to be a breeze—moving 560 miles from home didn’t seem particularly daunting after having lived thousands of miles away.” And speaking of college， improving your language skills might help you get into dream colleges and even land future jobs. Colleges and employers know that studying abroad provides leadership skills in a world that is increasingly globally interconnected. Most of all， it’s fun! You’re not likely to suffer from sophomore slump or general boredom while you’re studying in a different learning environment. What are the reasons for studying abroad besides the excitement of travel according to the passage?

A. You will experience new customs， holidays， foods， art， music， and politics firsthand.

B. You will meet lots of different people and pick up a language or two.

C. You will experience new cultures and gain self-confidence.

D. All of the above.

2. Passage Two When older people can no longer remember names at a cocktail party， they tend to think that their brainpower is declining. But a growing number of studies suggest that this assumption is often wrong. Instead，the research finds， the aging brain is simply taking in more data and trying to examine carefully a lot of information， often to its long-term benefit. Some brains do deteriorate with age. But for most aging adults， researchers say， much of what occurs is a gradually widening focus of attention that makes it more difficult to get hold of just one fact. Although that can be frustrating， it is often useful. “It may be that distractibility is not， in fact， a bad thing，” said Shelley H. Carson， a psychology researcher at Harvard. “It may increase the amount of information available to the conscious mind. ” For example， in studies where subjects are asked to read passages that are interrupted with unexpected words or phrases， adults 60 and older work much more slowly than college students. Although the students plow through the texts at a consistent speed regardless of what the out-of-place words mean， older people slow down even more when the words are related to the topic at hand. That indicates that they are not just stumbling (结结巴巴地念) over the extra information， but are taking it in and processing it. When both groups were later asked questions for which the out-of-place words might be answers， the older adults responded much better than the students. “For the young people， it’s as if the distraction never happened，” said a researcher of the review， Lynn Hasher， a professor of psychology at the University of Toronto. “But for older adults， because they’ve retained all this extra data， they’re now suddenly the better problem solvers. They can transfer the information they’ve soaked up from one situation to another.” Such tendencies can yield big advantages in the real world， where it is not always clear what information is important， or will become important. For instance， a seemingly irrelevant point or suggestion in a memo can take on new meaning if the original plan changes. What does Shelley H. Carson mean by saying “. .. distractibility is not， in fact， a bad thing”【Line 1， Para. 3】?

A. It is not important to concentrate on one thing.

B. Distractibility can improve people＇s brainpower.

C. Being distracted means taking in more information.

3. Passage One There are three separate sources of danger in supplying energy by nuclear power. First， the radioactive material must travel from its place of production to the power station. Although the power stations themselves are strongly built， the containers used for the transport of the materials are not. Normally， only two methods of transport are in use， namely road or rail. Unfortunately， both of these may have an effect on the general public， since they are sure to pass near， or even through， heavily populated areas. Second， there is the problem of waste. All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these wastes nonradioactive， so they must be stored in one of the inconvenient ways that scientists have invented. For example， they may be buried under the ground， or dropped into deserted mines， or sunk in the sea. However， these methods do not solve the problem， since an earthquake could easily break the containers.
Third， there may occur the danger of a leak or an explosion at the power station. Compared with the other two dangers， this is not very likely， so it does not provide a serious objection to the nuclear program. However， it can happen. Separately， these three types of dangers are not a great cause for worry. Taken together， though， the probability of disaster is extremely high. What do we learn from the last paragraph?

A. By itself， none of the three dangers is very likely to cause much worry.

B. The dangers of nuclear energy can be prevented.

C. The general public are strongly against the nuclear program.

D. The power station is a safe place.

4. Passage Eight Wisdom teeth are normally the last teeth to appear. This usually happens when people are in their late teen years or early twenties—in other words， when they are older and wiser. Wisdom teeth are chewing teeth， at the back of the mouth. They can grow into place normally and never cause a problem. But often there is not enough room for them in the mouth. They might crowd other teeth. Sometimes they even push sideways through the gums (牙床). An impacted wisdom tooth is one that fails to completely rise through the gum—the term is 【erupt】. Wisdom teeth that only partially erupt can leave space for bacteria to enter around the tooth. Infection is a risk in these cases. Wisdom teeth that are not well in place and become impacted are often removed. People should have the placement of their wisdom teeth examined between the ages of sixteen and twenty. X-rays can show wisdom teeth that are below the gums. The American Dental Association says removal is generally advised when wisdom teeth only partly break through the gums. Removal is also advised if there is a chance that poorly placed wisdom teeth will damage other teeth. And removal is called for in cases where fluid collects around a wisdom tooth that is partly or fully below the gum. But why do we have wisdom teeth if we often need to get them removed? One theory has to do with our diets. Scientists say the diet of prehistoric humans probably required more chewing teeth. Life was probably alittle rougher on the teeth back then， too. So it was good to have extras. The American Association of Oral and Maxillofacial (上颌面的) Surgeons says young adults are the best candidates for wisdom teeth removal. The group says older patients may be at greater risk for disease in the tissue surrounding the teeth. After surgery， there can be swelling of the gums and face and some pain. Both can be treated with cold wraps and medication (药物治疗). Humans have wisdom teeth probably because ( ) .
