    题目列表(包括答案和解析)

    When you cut your skin, you bleed(流血). If a person loses a lot of blood, he will become ill and may die. Blood is very important. People have always known that. At one time, some people even drank blood to make them strong!

    When doctors understand how blood goes around inside the body, they try ways of giving blood to people who need it. They take blood from the healthy people and give it to people who need it. This is called " blood transfusion（输血）". The blood goes from the arm of the healthy person into the arm of the sick person.

    But there are two problems. First, it does not always work. Sometimes people die when they have blood transfusion. Later, doctors find that we do not all have the same kind of blood. There are four groups—O, A, B and AB. We all have blood of one of these groups. They also find that they can give any kind of blood to people of group AB. But they find that they must give A-group blood to A-group people and B-group blood to B-group people. I have O-group blood and the doctor told me that I could give blood to anyone else safely.

    There is another problem. To give blood of the right kind, doctors have to find a person of the right blood group. Often they can not find a person in time. If they have a way to keep the blood until someone needs it, they can always have the right kind of blood. At first they find they can keep it in bottles for fifteen to twenty days. They do this by making it very cold. Then they find how to keep it longer. In the end they find a way of keeping blood for a very long time.

    We call a place where we keep money a "bank". We call a place where we keep blood a "blood bank". One day, when you grow up, you may decide to give blood to a "blood bank". In this way you may stop someone from dying. Or perhaps one day you may become ill. You may need blood. The "blood bank" will give it to you.

    1.From the passage, we learn that sometimes people die when they have blood transfusions because they __________ .

    A. are given the cold blood???????????? B. lose too much blood

    C. are given the wrong kind of blood????? D. are O-group people

    阅读理解。
         Almost every day, we discuss the topic of health, especially for kids. But what is health? "Health"
    means eating well, getting enough exercise, and having a healthy weight. Let's read the following rules.
    They can help you stay healthy.
    1. Eat a variety of foods, especially fruit and vegetables. We all know that eating fruit and vegetables
    can help us stay healthy, but many of us only eat our favorite foods. Remember that we can only get
    the nutrition(营养) we need by eating different kinds of food, especially fruit and vegetables.
    2. Drink water and milk most often. Everyone knows that water is important. Besides that, kids need
    plenty of calcium(钙) to grow strong bones, and milk has  a  lot of it.  Every day, you should drink at
    least three cups of milk(1300 milligrams of calcium), when you are  9  years  old or older. You should
    also try to have less sugary drinks, like soda and cola. They include a lot of sugar. Sugar just includes
    calories, not important nutrition.
    3. Listen to your body. When you are eating, notice how your body feels. When  your  stomach feels
    comfortably full, stop eating. Eating too much makes you feel uncomfortable. If  you  do it too often, it
    can make you unhealthy and fat.
    4. Limit(限制) screen time. What's  screen  time? It's  the  amount  of  time  you spend watching TV,
    movies, and playing computer games. The  more  time you spend on these  sitting-down  activities, the
    less time you spend  playing  sports, like  basketball,  and  doing  other  activities  like bike riding and
    swimming. Try to spend no more than 2 hours a day on screen time.
    1. In this passage, "health" includes all of the following EXCEPT(除了) ________.      
    A. eating well
    B. doing more exercise
    C. having a healthy weight
    D. wearing comfortably
    2. The underlined phrase "a variety of" means ________.          
    A. lots of  
    B. all kinds of  
    C. the rest of  
    D. a lot of
    3. Which of the following is NOT true?
    A. Eating more fruit and vegetables is difficult for some people.
    B. We should eat and drink something with less sugar.
    C. When we are full, we should stop eating, however(不管怎样) delicious the food is.
    D. We should spend the same time on both sitting-down activities and on sports.      
    4. As kids, we should drink at least ________ to grow strong bones.
    A. four cups of milk
    B. three cups of milk
    C. two cups of milk
    D. one cup of milk
