    The world is not hungry, but it is thirsty. It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why? Because about 97% of water on the earth is sea water which we can’t drink or use for watering plants directly. Man can only drink and use the 3% the water that comes from rivers and lakes. And we can’t even use all of that, because some of it has been polluted.
    Now more water is needed. The problem is: can we avoid a serious water shortage later on? First, we should all learn how to save water. Secondly, we should find out the ways to reuse it. Scientists have always been making study in this field. Today, in most large cities water is used only once and then runs to the sea or rivers. But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next?
    The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it’s already in use in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we’ll be in no danger of drying up.
    【小题1】The world is thirsty because ___________.

    A．3/4 of the earth is covered with water
    B．we have enough sea water

    A．3% of drinkable water on the earth is from rivers and lakes.
    B．75% of water on the earth is in the sea.
    C．97% of the earth is covered with water.
    D．3% of water on the earth is sea water.
    【小题3】From the passage we learn that __________.
    A．if every city reuses its water, we’ll be in no danger of drying up
    B．man can only drink and use about 25% of water on the earth
    C．today in most large cities water is used only once

    Want to lose weight? Try eating. That’s one of the ways being developed by scientists experimenting with foods that trick the body into feeling full.
    At he Institute of Food Research in Norwich, England, food expert Peter Wilde and his colleagues are developing foods that slow down the digestive system, which then sends a signal to the brain that stops appetite. “That fools you into thinking you’ve eaten far too much when you really haven’t,” said Wilde. From his studies on fat digestion, he said it should be possible to make foods, from bread to yoghurt, that make it easier to diet. While the research is still in its early stages, Wilde’s approach to controlling appetite is one that some doctors say could be a key to solving the problem of obesity.
    “Being able to switch off appetite would be a big help for people having trouble losing weight,” said Steve Bloom, a professor of investigative medicine at London’s Imperial College, who is not connected to Wilde’s research. Bloom said that regulating appetite through foods is theoretically possible. But Bloom warned that controlling appetite may be very challenging. “The body has lots of things to prevent its regulatory systems from being tricked,” he said.
    Wilde’s research makes use of the body’s ways of digesting fat. Fat normally gets broken down in the first part of the small intestines (肠道). When you eat a high-fat meal, however, the body can only digest the fat entirely further down in the intestines, which then causes the body to produce a kind of chemical to stop the appetite.
    Wilde’s approach copies what happens with a high-fat meal. He coats fat droplets (滴) in foods with modified proteins from plants, so it takes longer for the chemical that breaks down fat to reach it. That means that the fat isn’t digested until it hits the far reaches of the intestines. At that point, intestinal cells send a signal telling the brain it’s full. Even though the body hasn’t had a high-fat meal, it stops the appetite as if it has. If the fat had been digested earlier in the intestines, no such signal would be sent.
    51. According to Wilde’s research, what could people do if they want to lose weight?
    A. Eat more bread and yoghurt.                    B. Trick the body by eating nothing.
    C. Have foods with fat droplets coated.         D. Control their digestive system strictly.
    52. The underlined word “obesity” in Para. 2 most probably means “________”.
    A. being too fat                            B. eating too much food       
    C. stopping appetite                D. being unhealthy
    53. What can be inferred about Professor Bloom’s opinion towards Wilde’s approach?
    A. It won’t work since the body’s regulatory systems will never be tricked.
    B. It is sure to switch off the appetite of people with a weight problem.
    C. It sounds terrible because regulating appetite through foods is not practical at all.
    D. It’s no that easy to trick the body so more research should be done.
    54. Which of the following is TRUE about Wilde’s approach?
    A. A kind of chemical is added to make a high-fat meal less fatty.
    B. Fat is digested earlier and the body sends a signal telling the brain it’s full.
    C. Fat won’t get broken down in the first part of the small intestines.
    D. The chemical that breaks down fat will not reach the fat.
    55. The passage is written to ________.
    A. give advice on how to stop eating high-fat meals
    B. introduce a research on controlling appetite
    C. discuss the argument between two professors
    D. show different ways to trick the body

    My Uncle Dave posed an interesting question to my wife and me when he came to visit us the other day. He asked: “What do you think the world will be like in 50 or 100 years, in terms of technology and society and so on?”

    He says he asks many of the people he meets this question to see what their thoughts are. His point is that no one really knows. I mean, in 1945, could people have even imagined surfing the net or sending e-mails as we do? No way. And the pace of technological innovation(创新) is incredible (难以置信的). We’re on a more different curve than we used to be.

    One thing I’m looking forward to is real software agents. There is so much information out there, but I want something that can help me find what I really want. For instance, in about ten years, I think, there will be no longer recorded music, and there will be some big databases from which you can download music onto your hard drive or whatever. At that point, there will be so much music to choose from and you’ll be able to sample things before you buy them. But the question will be how I find what I’m looking for and how I do find the music that might interest me. Or more generally, how do I find information that I want without spending all the time myself surfing the net? How do I find people who are like-minded (具有相似目的), with whom I might really want to communicate? I want to find those people but it’s hard to do. In the future I think that one will be able to build a community of like-minded people who live all over the globe. It’s going to be very interesting, I think.

    1.No one really knows what the future will be like because _____.

    A．there is too much information for us to choose from

    B．technological development is too fast

    C．people live in different countries

    D．no one is intelligent enough to answer such a question

    2.The function of the first paragraph is to _____.

    A．explain the question given in this paragraph

    B．put forward the topic in this passage

    C．show Dave is a foolish man to ask such a question

    D．describe a picture about what the future will be like

    3.The writer is looking forward to some real software agents so as to _____.

    A．earn a lot of money

    B．communicate with some like-minded people

    C．help find the correct information needed

    D．spare some time for surfing the Internet

    4.The best title of this passage should be _____.

    A．What the Future Will Be Like

    B．Listen to Music Through the Internet

    C．Music and Software Development

    D．How to Live a Happy Life in the Future
