    Why does cream go bad faster than butter? Some researchers think they have the answer, and it comes down to the structure of the food, not its chemical composition(成分)—a finding that could help break away from some chemicals. Cream and butter contain pretty much the same things, so why cream should go bad much faster has been a problem. Both are small globules(液滴) of one liquid spread throughout another. The difference lies in what’s in the globules and what’s in the surrounding liquid, says Brocklehurst, who led the research. In cream, fatty globules drift about in a sea of water. In butter, globules of a watery road are locked away in a sea of fat. The bacteria(细菌) which make the food go bad prefer to live in the watery areas of the mixture. “This means that in cream, the bacteria are free to grow throughout the mixture, ” he says. When in butter, the bacteria are locked away in locked places buried deep in the sea of fat. Trapped in this way, those colonies cannot spread and rapidly run out. They also slowly poison themselves with their waste products. “In butter, you get a self-limiting system which stops the bacteria growing, ” says Brocklehurst. The researchers are already working with food companies eager to see if their products can be made to stand bacterial attack through changes of the food’s structure. Brocklehurst believes it will be possible to make something used in salad cream for instance, more like that in butter. The key will be to do this while keeping the salad cream liquid and not turning it into a solid state.

    1. The importance of Brocklehurst’s research is that _______.

    A. it suggested a way to keep some foods fresh without using some chemicals

    B. it discovered small globules in both cream and butter

    C. it showed the secret of how bacteria increase in cream and butter

    D. it found that cream and butter share the same chemical composition

    2. According to the researchers, cream goes bad faster than butter because bacteria _______.

    A. are stronger in cream

    B. increase their number more easily in cream than in butter

    C. live on less fat in cream than in butter

    D. produce less waste in cream than in butter

    3. According to Brocklehurst, we can keep cream fresh by _______.

    A. removing its fat　　　　　　　　　　　　　　　　　　 B. killing the bacteria

    C. reducing its water　　　　    　　　　　　　　　　 D. changing its structure

    4. The underlined word “colonies” refers to _______.

    A. tiny globules　　　　　　　　　　　　　　　　　　　　 B. watery regions

    C. bacteria society　　　　　　　　　　　　　　　　　　 D. little departments

    5. Commercial(商业的) use of the research finding will be possible if salad cream can be made to stand bacterial attack _______.

    A. by changing its chemical composition

    B. by turning it into a solid lump

    C. while keeping its structure unchanged

    D. while its liquid form remains

    Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.
    Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”. Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质), like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.
    Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality (人的个性).Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
    Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
    If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser. 
    【小题1】According to the passage _________.

    A．we should always keep fit
    B．if we were healthy, we could spend our days in doing things with less sleep
    C．one can eat a lot to stay in good shape

    A．we should eat a lot of sweets
    B．one needs a large amount of fat
