    People are busy working every day, so they do not have enough time to do exercises. As a result, many people become too fat or too thin. To keep our bodies healthy, we have to do exercises every day.
    There are many kinds of exercises. Bending (弯腰) and stretching (伸展) helps us move easily. Before we play ball games or swim, it is better for us to do bending and stretching exercises first. This kind of exercise is sometimes called warm-up exercise. Running is also a good exercise. If we cannot run fast, we can Jog. Jogging means running slowly. Again, before we run or jog, we must do warm-up exercises. Also, we should not run or jog in busy streets. The air there is often dirty. Some people like weight lifting (举重)because it can make their bodies strong. Also, we need to do some warm-up exercises before weight lifting.

    In most parts of the world, many students help their schools make less pollution. They join “environment clubs”. In an environment club, people work together to make our environment clear.
    Here are some things students often do.
    No-garbage lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school!
    No-car day. On a no-car day, nobody comes to school in a car--- not the students and not the teachers! Cars give pollution to our air, so remember: Walk, jog, bike or run. Use your legs! It’s lots of fun!
    Turn off the water! Do you know that some toilets can waste twenty to forty m3  of water an hour! In a year, that would fill a small river! In environment clubs, students mend those broken toilets. We love our environment. Let’s work together to make it clean.

    The human body is a living machine, and, like all machines, it needs “fuel” to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy?
    The energy value of food is usually measured in calories(卡). A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different, as the picture shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on.
    The energy in food is in the form of three kinds of chemical materials—carbohydrate（碳水化合物）, protein（蛋白质） and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show.
    (P= protein      C= carbohydrate    F=fat)
    小题1:How many calories are needed to raise the temperature of 5kg of water from 35℃ to 90℃?
    A．55.B．175.C．325.D．275.
    小题2:Which of the following contains the most amount of calories?
    A．Milk.B．RiceC．Peanuts.D．Milk or peanuts.
    小题3:Who needs the most amount of calories each day?
    A．A woman.B．An office worker.C．A farmer.D．A boy aged 16.
    小题4:Which of following is True?　　
    A．You need more calories for swimming than for mountain climbing.
    B．A child aged 8 needs the same amount of calories every day as a man over 70 does.
    C．A woman feeding baby needs over 4 times the amount of calories that a baby does.
    D．Everyone needs the same amount of calories per day.
    小题5:This passage mainly tells us ______.
    A．all the energy is in food
    B．the human body needs energy
    C．the number of calories depends on your activity
    D．we must only eat peanuts to get calories

    Are some people born clever, and others born stupid? Or is intelligence (智力) developed by our environment and our experience? Strangely enough, the answer to these questions is yes. In some degree, our intelligence is given to us at birth, and no education can make a genius (天才) out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich environment. Therefore, the limits of person’s intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This point of view, now is held by most experts.
    It is easy to show that intelligence is something that we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligence. If we take two strangers by chance from the population, it seems that their degree of intelligence will be completely different. If, on the other hand, we compare two twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
    Imagine now that we take two twins and put them in different environments. We might send one, for example, to a university and the other to a factory separately where the work is boring. We would soon find differences in intelligence developing, and this shows that environment as well as birth plays an important role. This conclusion is also suggested by the fact that people who live in close contact (接触) with each other, but who are not related at all are likely to have similar degree of intelligence.
    小题1:How is man’s intelligence given?
    A．At birthB．Through education
    C．Both at birth and through educationD．Neither at birth nor through education
    小题2:What does the underlined word mean in the first paragraph?
    A．稳固B．确定C．修理D．安排
    小题3:According the passage, if a child is born with low intelligence, what might happen to him later?
    A．Become a genius.
    B．Still become a genius if he should be given special education.
    C．Reach his intelligence limits in rich environment.
    D．Never reach his intelligence in his life.
    小题4:What can we learn from the example of the twins going to a university and to a factory?
    A．The importance of their intelligence.
    B．The role of environment on intelligence.
    C．The importance of their jobs
    D．The part that birth plays
    小题5:What statement is TRUE according to the passage?
    A．No education can help make a genius.
    B．Personality is important as intelligence which was given to people at birth.
    C．People who have similar degree of intelligence must be relatives.
    D．Environment influences people in intelligence developing.

    Different weather makes people feel different. It influences (影响) health, intelligence (智力) and feelings.
    In August, it is very hot and wet in the southern part of the United States. People there have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is very hot at some times and very cold at other times. People in these states have more heart trouble after the weather changes in February or March.
    The weather can also influence intelligence. For example, in a 1983 report by scientists, IQ (智商) of a group students were very high when a very strong wind came, but after the strong wind, their IQ was 10% below. The wind can help people have more intelligence. Very hot weather, on the other hand (另一方面), can make it lower. Students in many schools of the United States often get worse on exams in the hot months of the year (July and August).
    Weather also has a strong influence on people’s feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel unhappy during cold weather. But fat people may have a hard time in hot summer. At about 18C, people become stronger.
    Low air pressure (气压) may make people forgetful. People leave more bags on buses and in shops on low-pressure days. There is a “good weather” for work and health. People feel best at a temperature of about 18 centigrade (摄氏度).
    Are you feeling sad, tired, forgetful, or unhappy today? It may be the weather’s problem.
    小题1:People may have more intelligence when _____ comes.
    A．a rain B．very hot weather
    C．a strong wind D．low air pressure
    小题2:Low air pressure may make people _______.
    A．forgetful B．sad C．angry D．tired
    小题3:In “good weather” of 18 centigrade, _______.
    A．people are very forgetful
    B．people can’t do their work well
    C．thin people feel cold
    D．people are in better health
    小题4:The writer wants to tell us that _______.
    A．hot and cold weather influences all people in the same way
    B．weather influences people’s lives
    C．IQ never changes during weather changes
    D．There is a good kind of weather for people’s work and health

    American Classroom Rules
    1. If the teacher asks a question, you should give an answer. If you do not understand the question, you should put up your hand and ask the teacher to repeat the question. If you don’t know the answer, it’s all right to tell the teacher that you don’t know. Then he or she knows what you need to learn.
    2. There is no excuse for not doing your homework. If you can not go to school, you should call your teacher or your classmate and ask for the homework. It is your responsibility（责任）to find out what homework you have missed. It is not the teacher’s job to remind you of missed homework.
