    A science book gives facts. Some science books tell us about animals. Some tell us about plants. Some tell us about outer space. This page tells us about animals.

    阅读下列短文，根据短文中的信息完成文后表格。在答题卡标有题号的横线上，写出空缺处所填单词的正确形式。（每空一词）
    In classroom, your teachers will talk about topics that you are studying. The information they provide will be important for you to know when you take tests. So you must be able to take good written notes from what your teachers say.
    Here are the three stages(阶段) of taking notes and what you should do during each stage.
    Before Class
    Review your notes you have taken before you come to class. This will be good for remembering what was covered. Get you ready to understand new information your teacher will provide.
    During Class
    Keep your attention on what your teacher is saying and “the signal words” that tell you what your teacher is going to say and it is important to write in your notes. Examples of signal words are “The most important point…” and “Remember that…”. Be sure to include in your notes information that your teacher repeats or writes on the blackboard. Write quickly so that you can include all the important information in your notes. Do this by writing abbreviations such as med for medicine, using symbols such as % for percent, and writing short sentences.
    After Class
    Rewrite your notes to make them more complete and accurate(准确的) by changing abbreviations into whole words, symbols into words, and shortened sentences into longer sentences. Use them to answer your questions. If necessary, ask your teacher for help.

    Fashions in child-care (儿童保育)， as all parents know, come and go. Bottle-feeding or mother's milk?  Full-time parental care or a child-minder(儿童保育员)? These problems always trouble the parents a lot. And now, there is a book called Childsplay dealing with the problem of child-care.
    The author of Childsplay, Lucy Jackson, believes most school children do some sports at school. And many adults take regular exercise in their free time.
    Babies, though, spend most of the time in front of the television or sitting in a push-chair (折叠式婴儿车) or high chair. If the world were a safer place, every child would run around freely, but that is simply not possible. As a result, they become lazy, overweight and unfit.
    Ms. Jackson is worried that if small children take no regular exercise, bad habits will continue into adulthood (成人期 ). She suggests that parents should begin exercising with very small babies, moving their legs and arms gently in time to music. As children grow, they should follow and exercise program using soft balls, household furniture and play equipment.                                    
    Many experts in child development do not agree. They feel that children will learn to run and jump as they play naturally; they do not need planned exercise. They would not be overweight if they ate healthier food. An increasing number of parents, though, are taking their children to exercise classes. The kids jump around with their mothers to disco music.They seem to enjoy themselves, but it is not at all clear if the classes have any effect on their future development.
    小题1:According to the passage, the parents do not worry about how to care about their children.
    小题2:Childsplay is a book about how to take care of the children.
    小题3:Ms. Jackson doesn't believe babies take enough exercise.
    小题4:Ms. Jackson encourages parents to take exercise with their babies.
    小题5:Though we don’t know if the exercise will have any effect on children future development, some mothers have already taken their children to exercise.

    A kind of little cars may some day take the place of today’s cars. If everyone drives such cars in the future，there will be less pollution from the cars. There will also be more space for parking cars in cities，and the streets will be less crowded. Three such cars can park in the space now needed for one car of the usual size.
    The little cars will cost much less to own and to drive. Driving will be safer，too，as these little cars can go only 65 kilometers an hour.

    What do you usually do to get pocket money from your parents? In western countries, many children do chores to get pocket money. They usually start to do this at 10 years old.
    School students have to do homework and study for tests. They don’t have a lot of free time in the week. They often do chores at the weekend.
    Young kids only do easy chores. So they don’t get much money. But that’s all right. Many of them only want to buy candy. And candy is cheap! They help wash up after dinner and feed the family cat or dog.
    When they get older, kids want to buy more and more things. They want things that are more expensive than candy. Then they have to work harder! They often wash the family car, cut the grass, walk the dog and cook dinner.
    Some jobs are a good way for kids to learn new things. For example, they can learn to use a lawnmower(割草机) or how to cook. Of course, their parents help them at first.
    小题1:How do the children in western countries get pocket money?
    小题2:When do they usually start to get pocket money?
    小题3:Why do the school students usually do chores at the weekend?
    小题4:Why do the elder kids have to work harder?

    Food waste has become a big problem in China.
    Zhou Jinsong, a canteen(食堂) manager at Central South University, said that students produce over 12 barrels(桶) of leftovers every day — each barrel stands at one meter in height. Zhou’s canteen is just one of several on the campus.
    According to Xinhua News Agency, the food wasted by Chinese people equates to about 50 million tons of grain every year, or 10 percent of the country’s total annual grain production. This food could feed another 200 million people. What students waste every year could feed over 10 million people. Students nowadays are well protected by their families and hardly know how hard farmers work to provide them with the food they eat.
    “Since the 1980s, when Chinese gradually became richer, food waste has been a subject of debate. But things have hardly changed over the years,” said Yu Changjiang, a sociologist at Peking University. “It’s the Chinese way of showing respect to friends, often referred as Mianzi.”
    But rather than tradition, huge public spending on government banquets(宴会) is also causing food waste, said Zhou Xiaozheng from the sociology department at Renmin University of China. “It’s the result of widespread reception meals at government levels. It is also important that everyone thinks about how they can do their best to reduce food waste.”
    小题1:Which of the following statements is not the reasons for food waste?
    A．Students hardly know farmers’ hard work on the farm.
    B．The government spends a large amount of money on government banquets.
    C．Leaving some food after a banquet is the Chinese way to show respect to guests.
    D．The food in the college canteen is not delicious.
    小题2:Where can we probably read this passage?
    A．In a newspaper.B．In a traffic report.
    C．On a health website.D．In a story book.
