    Some people have it easy. When their kids ask them what they do at work, they can give a simple, direct answer: “I put out fires” or “I teach primary school”. As a theoretical physicist, I never had this luck. Society has come to expect many things from the physicists. It used to be that we only had to discover the basic laws of the world and supply the techniques that would power the next Silicon Valley. With these expectations we were fairly comfortable: they are the sorts of things we think we know how to do. What makes us uncomfortable and what makes it hard for us to tell our kids what we’re up to is that in this century we have become, though unwillingly, gurus on questions such as “What is the nature of Reality?”
    We now deal with a whole new class of problems. We ask how the world began and what the nature of matter is. The answers we are coming up with are just not easy to comprehend for the average person.
    So, when physicists get out of their cars in the morning, have a cup of coffee and sit down in front of their computers, they leave a familiar world and enter a place where things act in strange ways that are impossible for ordinary people to understand.
    72. According to the passage, in a way physicists are        .
    A. honest        B. comfortable    C. strange        D. unlucky
    73. By what the writer says about physicists, we know that physicists        .
    A. don’t like their careers
    B. live in two different worlds
    C. are coming up with new answers to old questions
    D. don’t have to tell people what they are doing
    74. From the passage we can conclude that theoretical physicists        .
    A. contributed to the new industry in Silicon Valley
    B. only have to answer the basic questions about the world
    C. have disappointed the expectations of many people
    D. have found it hard to make themselves popular
    75. What’s the main idea of the passage?
    A. Society seems to know a bit about physicists’ work.
    B. Most people are expecting to know what physicists are doing.
    C. Physicists are doing more and more difficult jobs.
    D. It’s impossible for average people to know physicists’ work.

    第三部分:阅读理解(共20小题,每题2分,共40分)
    第一节：（共15小题,每题2分,共30分）
    阅读下面四篇短文，从四个选项（A、B、C、D）中，选出最佳选项，并在答题卡上将该项涂黑。
    A
    Recently, a professor of philosophy in the United States has written a book called Money and the Meaning of Life. He has discovered that how we deal with money in our day-to-day life has more meaning than we usually think. One of the exercises he asked his students to do is to keep record of every penny they spend for a week. From the way they spend their money, they can see what they really value in life.
    He says our relation with others often becomes clearly defined when money enters the picture. You might have wonderful friendship with somebody and you think that you are a very good friend. But you will know him only when you ask him to lend you some money. If he does, it brings something to the relationship that seems stronger than ever before. Or it can suddenly weaken the relationship if he doesn’t. This person may say that he has a certain feeling, but if it is not carried out in the money world, there is something less real about it.
    Since money is so important to us, we consider those who possess a lot of it to be very important. The author interviewed some millionaires in researching his book.
    Question: What is the most surprising thing you have discovered abotrt being rich, because you are a self-made man?
    Answer: The most surprising thing is how people give me so much respect. I am nothing. I do not know much. All I am is rich.
    People just have an idea of making more and more money, but what is it for? How much do I need for any given purposes in my life? In his book, the professor uncovered an important need in modern society: to bring back the idea that money is an instrument rather than the end. Money plays an important role in the material world, but expecting money to bring happiness may be missing the meaning of life.
    56. The author seems to believe that asking your friend to lend you some money_______.
    A. is a good way to test your friendship     B. will do harm to your friendship
    C. will strengthen your friendship           D. is a good way to break off your friendship
    57. What can we learn about the millionaire from his answer in the interview?
    A. He does not feel that he is well educated.
    B. He does not think that he is a very important person.
    C. He doesn’t think that being rich is worth so much attention.
    D. He does not consider himself to be very successful
    58. What does the American professor of philosophy want to explain in his book?
    A. Money is an end.         B. Money is a means.
    C. Money is everything.      D. Money is unimportant.
    59. Which of the following might the author disagree with?
    A. Money is important in modern society.
    B. The meaning of life does not completely lie in money.
    C. Wealth will surely bring the owner happiness.
    D. Happiness is not necessarily the result of wealth.
