As many as one in five US teenagers have some degree of hearing loss, according to researchers.

They say the problem is growing.

   Teenagers really don’t pay attention to how much noise they are exposed (暴露) to, Josef Shargorodsky of Brigham and Women’s Hospital in Boston told Reuters. “Often people won’t notice it, but even slight hearing loss may affect language development,” said Shargorodsky, one of the researchers.

    The study compared surveys from the early 1990s and the mid-2000s. Each included a few thousand teenagers. In the first survey, about 15 percent of teenagers had some degree of hearing loss. Some 15 years later, that number had risen by a third, to nearly 20 percent.

    “This certainly is big news,” said Alison Grimes, an ear doctor. Hearing loss is very common in old people, Grimes said, but she added that it was worrying to see it happen in the younger age group.

    In babies and young children, hearing problems are known to slow language development. The science is less clear for teenagers, but it is easy to imagine how being hard of hearing could affect learning, said Grimes,.

    The reasons for the rise are still unclear. When researchers asked teenagers about noise exposure – on the job, at school or from activities, for example – the teenagers didn’t report any change. But Shargorodsky said that might not be true. “We knew from before that it is difficult to ask this age group about noise exposure – they underestimate (低估) it.” Few people would call it noise when they listen to music on their MP3 player, for example. “There is a difference between what we think is loud and what is harmful to the ear,” said Grimes.

    Although it’s not clear that the MP3 players cause teenagers’ hearing loss, Grimes said it was still a good idea to turn down the sound and take short breaks from listening.

According to the researchers, in a US class of 40 students, about ____ students have some degree of hearing loss.

A. one              B. five             C. six           D. eight

Which of the following statements is true according to the article?

A. Slight hearing loss does not influence learning.    

B. Only a few old people have hearing problems.

C. Hearing problems can slow language development.  

D. Noise exposure is clearly noticed by teenagers.

About hearing loss, it can be inferred that ________.

A. the reasons for the rise have been found           B. MP3 players are to blame

C. listening to loud music may be a cause            D. noise is the main reason

The article was written to ______.

A. warn teenagers that loud music might be harmful

B. explain what kinds of noises might affect studies

C. suggest that teenagers shouldn’t listen to loud music

D. show how important hearing can be for learning

閱讀理解

　　Most people believe they don't have much imagination．They are wrong．Everyone has imagination, but most of us, once we become adults, forget how to access it．Creativity isn't always connected with great works of art or ideas．People at work and in their free time routinely think of creative ways to solve problems．Maybe you have a goal to achieve, a tricky question to answer or you just want to expand your mind! Here are three techniques to help you．

　　This technique involves taking unrelated ideas and trying to find links between them．First, think about the problem you have to solve or the job you need to do．Then find an image, word, idea or object, for example, a candle．Write down all the ideas/words associated with candles：light, fire, matches, wax：night, silence, etc．Think of as many as you can．The next stage is to relate the ideas to the job you have to do．So imagine you want to buy a friend an original present; you could buy him tickets to a match or take him out for the night．

　　Imagine that normal limitations don't exist．You have as much time/space/money, etc．a(chǎn)s you want．Think about your goal and the new possibilities．If, for example, your goal is to learn to ski, you can now practice skiing every day of your life(because you have the time and the money)．Now adapt this to reality．Maybe you can practice skiing every day in December, or every Monday in January．

　　Look at the situation from a different point of view．Good negotiators(談判者)use this technique in business, and so do writers．Fiction writers often imagine they are the characters in their books．They ask questions：what does this character want? Why can't she get it? What changes must she make to get what she wants? What does she dream about? If your goal involves other people, put yourself "in their shoes"．The best fishermen think like fish!

(1)

According to the passage, when we become adults _________．

[　　]

A．

we can still learn to be more creative．

B．

C．

we are not as imaginative as children．

D．

we are unwilling to be creative．

(2)

The second technique suggests that you just imagine _________．

[　　]

A．

setting a goal is as simple as skiing．

B．

you have every resource to achieve your goal．

C．

new possibilities will soon appear．

D．

December and January are the best months for skiing．

(3)

The phrase “put yourself in their shoes” in paragraph 4 is closest in meaning to _________．

[　　]

A．

dress yourself like them．

B．

do as they ask you to．

C．

think as they would．

D．

put on their shoes,

(4)

We learn from the third technique that a good salesman should ask himself：

[　　]

A．

what do I usually do?

B．

what did my boss tell me to do?

C．

what are my customers' needs?

D．

how should I sell my products?

Passage four(preface)
Science is a dominant theme in our culture. Since it touches almost every facet of our life, educated people need at least some acquaintance with its structure and operation. They should also have an understanding of the subculture in which scientists live and the kinds of people they are. An understanding of general characteristics of science as well as specific scientific concepts is easier to attain if one knows something about the things that excite and frustrate the scientist.
This book is written for the intelligent student or lay person whose acquaintance with science is superficial; for the person who has been presented with science as a musty storehouse of dried facts; for the person who sees the chief objective of science as the production of gadgets; and for the person who views the scientists as some sort of magician. The book can be used to supplement a course in any science, to accompany any course that attempts to give an understanding of the modern world, or – independently of any course – simply to provide a better understanding of science. We hope this book will lead readers to a broader perspective on scientific attitudes and a more realistic view of what science is, who scientists are, and what they do. It will give them an awareness and understanding of the relationship between science and our culture and an appreciation of the roles science may play in our culture. In addition, readers may learn to appreciate the relationship between scientific views and some of the values and philosophies that are pervasive in our culture.
We have tried to present in this book an accurate and up-to-date picture of the scientific community and the people who populate it. That population has in recent years come to comprise more and more women. This increasing role of women in the scientific subculture is not an unique incident but, rather, part of the trend evident in all segments of society as more women enter traditionally male-dominated fields and make significant contributions. In discussing these changes and contribution, however, we are faced with a language that is implicitly sexist, one that uses male nouns or pronouns in referring to unspecified individuals. To offset this built-in bias, we have adopted the policy of using plural nouns and pronouns whenever possible and, when absolutely necessary, alternating he and she. This policy is far form being ideal, but it is at least an acknowledgment of the inadequacy of our language in treating half of the human race equally.
We have also tried to make the book entertaining as well as informative. Our approach is usually informal. We feel, as do many other scientists, that we shouldn’t take ourselves too seriously. As the reader may observe, we see science as a delightful pastime rather than as a grim and dreary way to earn a living.
1.According to the passage, ‘scientific subculture’ means
A.cultural groups that are formed by scientists.
B.people whose knowledge of science is very limited.
C.the scientific community.
D.people who make good contribution to science.
2.We need to know something about the structure and operation of science because
A.it is not easy to understand the things that excite and frustrate scientists.
B.Science affects almost every aspect of our life.
C.Scientists live in a specific subculture.
D.It is easier to understand general characteristics of science.
3.The book mentioned in this passage is written for readers who
A.are intelligent college students and lay person who do not know much about science.
B.are good at producing various gadgets.
C.work in a storehouse of dried facts.
D.want to have a superficial understanding of science.
4.According to this passage,
A.English is a sexist language.
B.only in the scientific world is the role of women increasing rapidly.
C.women are making significant contributions to eliminating the inadequacy of our language.
D.male nouns or pronouns should not be used to refer to scientists.
5.This passage most probably is
A.a book review.
B.the preface of a book.
C.the postscript of a book.
D.the concluding part of a book.

       Directions: Read the following passage. Fill in the numbered blanks by using the information from the passage.

Have you ever found yourself wondering what you’re going to do with your life? Should you pursue another career path or stick to it? This is often described as being at the crossroads. There’s nothing really wrong in being at the crossroads. However, it becomes harmful when you stay there for a very long time without doing anything productive.

What should you do then in order not to remain at the crossroads forever? Here are some tips.

List down the pros and cons. Don’t just think about them. Write them down and list as many things as you can in every column. The purpose is to ensure you can really reflect on them.

Get some advice. When you’re confused, it’s good to ask some people. You can refer your dilemma to your family or even a therapist. Also you can tell your problem to mature people who you think have gone through what you’re experiencing right now. Their wisdom and their success stories can provide you with a lot of inspiration and clearness on what path to choose.

Visualize (想象). Visualization is an excellent technique when you need to have a more vivid image on what you want to become. You can also do it on your own. There are two ways on how to do it.

First is the mirror technique. You stand in front of the mirror and look at yourself. Then start to imagine what you’d look like in five years from now. The other technique is through meditation and relaxation. You lie down flatly on a couch or any smooth surface. Make sure you’re comfortable. Then close your eyes and perform visualization.

Once you have a clearer picture on your choices, you can then feed your mind with subliminal (潛意識的) messages. You can repeat the following: “This is what I want myself to be.” Repeat the sentence as often as you can until you can feel yourself believing in the words.
