Kids often ask Scout Bassett, of Palm Desert, California, if she wishes she had two no
rmal legs.Scout, 18, answers, “No.I have never known anything different, and it would seem weird to me.Besides, if it weren’t for the missing leg, I wouldn’t have the opportunities I have today!”

Scout has faced big challenges.When she was only months old, she suffered from terrible burns.Her right leg was especially damaged, and doctors cut it off above the knee.When she was 14, she got a high-tech leg made for sports and put it to the test right away in a race for disabled athletes.“I remember being terrified because this was my first time,” she says.“But my doctor said,You have to start somewhere.”

Scout was waiting nervously for the race to start when athlete Sarah Reinestsen came up and said, “I’ve been doing this for a while.Let me give you some tips.”Reinertsen, who lost her leg when she was seven, is the first disabled women to have finished the Ironman Triathlon(铁人三项) in Hawaii.She works with an organization to help support people like Scout.

Reinertsen’s encouragement changed the teenager’s life.She lost that first race, but gained the confidence that she needed to compete.If Sarah could do it, she could too.Training hard, she now runs competitively and also finds time to share her story with school groups.

“Sometimes people look at me or at Sarah and think they have nothing in common with us.I tell them that even if you aren’t physically challenged, everybody has challenges of some kind — maybe with family, or homework, or friends.No matter what it is, you can overcome that obstacle,” she says.“Everything you need is inside your heart.Take small steps.As time goes by, the steps will get bigger and you will reach your dream.”

11.Why does Scout answer “No” when asked if she wants two normal legs?()

A.She’s scared of changing her current situation

B.She couldn’t have them even if she wanted to

C.She has never thought about it before

D.She’s satisfied with what she has achieved as a disabled

12.What dose the doctor mean by saying “You have to start somewhere”(Para.2)?()

A.She has to do it sooner or later

B.She has to find the right place to start

C.That will be a memorable first time

D.That is a perfect time to start

13.Scout’s childhood experiences ______.

A.were the cause of her shyness

B.were a nightmare until she reached 14

C.didn’t stop her from fulfilling herself

D.didn’t have much influence on her later life

A.Sarah shared her story with school students

B.Sarah started to compete at the age of seven

C.Scout has been inspired by Sarah’s success

D.Scout joined Sarah’s organization to help others

Doreen Sykora is now a junior at McGill University. She had a difficult time when she fi

rst began college. She said, “I was always well-prepared for my examination. 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.” Hitoshi Sakamoto, an anthropology student at Temple University in Tokyo reports similar experiences.

These two young students were experiencing something called test anxiety. Because 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 great! 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 Hitoshi in Tokyo, the results were the same. He is enjoying school a lot more and learning more.

11. What is the similarity between Doreen Sykora and Hitoshi Sakamoto?

A. Students from the same university. B. Failing in all the examinations.

C. Experiences of test anxiety. D. Having the same poor studying habits.

12. These are signs of test anxiety EXCEPT________.

A. worries about a test. B. stressed about a test.

C. low grades and poor study habits. D. nervousness during the test

13. What’s the purpose of some special university student-help courses?

A. To help students to reduce test anxiety.

B. To show a stress level experienced by students.

C. To learn more knowledge about test anxiety.

D. To have a better understanding of test anxiety.

14. What’s the meaning of “blank out” in paragraph 1?

A. To be like a blanket. B. To be sure of an answer.

C. To be relaxed. D. To be unable to think clearly.

15. What’s the organization of passage?

A. Examples — theories — ideas.

B. Problem — strategy — result.

C. General statement — examples — result.

D. Strategy — experiment — examples.

In 1665,an apple fell from a tree and landed near young Isaac Newton.Untold numbers of
people had seen apples fall and hadn’t given the matter a second thought.But Newton thought about it carefully and developed a cornerstone of modern science—the theory of gravity.

The ability to ask deep questions and look for answers lies at the heart of science.So it stands to reason that educators would want to bottle Newton’s brand of thinking and serve it to their students.

Common sense might argue that the best means to that end is to cram future scientists with chemistry,physics,biology,and mathematics.After all,Newton had an enormous appetite for science.

But Newton owned more books in the humanities than he did in the sciences,and his interest included subjects such an history,philosophy,and Greek mythology.

Could it be that thinking deeply about subjects such as history,philosophy,and religion makes one a better scientist?many top American schools think so.

The liberal arts is diversified toolbox.If you have only one way of looking at things,you will get stuck in the same place everybody else got stuck.If you’ve got different experiences,you may find other ways of solving the problem.”

It’s well known that the more we think,the better our neural connections.But liberal arts colleges go one step further.They argue that learning to think in one field may sharpen the ability to solve complex problems in a seemingly unrelated area.It may be a while before scientists establish the truth or falsity of this idea.In the meantime,some of the best minds in science are betting that it’s true.

“Learning about the great books and the humanities can stimulate the sort of brain waves that serve a scientist pretty well,” says Nobel prize winner Tom Cech—“The more types of thinking you have to do,the more skills you can bring to a scientific problem."

26.We learn from the first paragraph that ________.

A.the ability to think is of first importance to scientific discovery

B.nobody noticed apples falling from trees to the ground before Newton

C.Newton developed the theory of gravity by watching a falling apple

27.According to the passage, to help students become scientists, educators________.

A.should cram them with lots of science courses

B.should make them think in the way Newton did

C.should ask them deep questions and look for answers

D.should give them an enormous appetite for science

28.We learn from the passage that students who study science in a liberal arts college ________.

A.are required to take a number of courses in the humanities

B.are free to take whatever courses they like best

C.have a wide range of interests in history, philosophy and religion

D.spend more time studying arts and the humanities than the sciences

29.The idea that learning to think in one field may sharpen the ability to solve complex problems in a seemingly unrelated area is ________.

A.already proved to be true by scientists

B.accepted by the best people in science

C.a common belief among liberal arts colleges

D.gaining worldwide acceptance

30.In liberal arts colleges students are _______.

A.asked to bring a diversified toolbox to school

B.trained to think differently from everybody else

C.required to learn different kinds of skills

D.taught to look at things in different ways

Third culture kid is a term in English that is used to describe children who have grow
n up in a different culture to that of their parents.There are great things about experiencing such a unique childhood.Third culture kids can also face many challenges.

I was born in England, to English parents.When I was two years old my dad got a new job in Poland.Since then I have lived in four other countries around the world.Although I have a British passport,I sometimes don't feel very English at all!

One of the best things about moving around a lot when I was younger experiencing many diverse cultures and countries.I was able to try different foods, learn different languages, experience different traditions and meet people from different backgrounds.I am also lucky to have friends all over the world that I keep in regular contact with.

However, it wasn't always easy.It often felt like I had only just settled in to the new school city and culture before my parents told me we were moving again.Leaving my friends behind was damaging as a child.I have lost touch with many people I was very close to because one of us moved country.It was also very disorientating to have an English passport, but not feel very English at all.Because I had no access to English culture, returning home, often felt like visiting a foreign country.Happily, now I feel more at home in England—although the question, “where are you from?” still confuses me!
