    There are many problems connected with space travel. The first and greatest of them is gravity (地球引力). If you let your pencil drop to the floor, you can see gravity in action. Everything is down to the earth by magnetic force. The weight of something is another way of describing the amount of force exerted on it by gravity. A rocket must go at least 2, 500 miles an hour to take anyone beyond the gravity of the earth into space.

    Another problem is the strain that a person is subjected to when a rocket leaves the ground. Anything that is not moving tends to resist movement. As the rocket leaves the ground, it pushes upward, and the person is pushed back against the chair. During this thrust, gravity exerts a force on the body equal to nine times its normal force.

    Once out of the earth's gravity an astronaut is affected by still another problem—weightlessness. Here, if a pencil drops, it doesn't fall. If a glass of water is turned upside down, the water will not fall out. All of us who are used to gravity expect things to have weightless conditions. Recent long flights have shown that the body needs special exercise in a spaceship.

    　　  l. As a rocket leaves the ground, an astronaut experiences a force called——.

    　　　　 A. gravity　　　　　　　　   B. a push

      　　   C. downward force　　　　    D. strain

    　　 2. The force of gravity an astronaut is subjected to when the rocket leaves the ground is equal to

    　　　　 A. 7 times its downward force　　　　　　  B. 5 times its normal force

    　　　　 C. 3 times its upward force　　　　　　　　 D. 9 times its normal force

    　　 3. Which of the following is not true according to the passage?

    　　　　 A. Everything is down to the earth by magnetic force.

    　　　　 B. Recent long flights have shown that the body needs special exercise in spaceship.

    　　　　 C. A rocket must go at most 2, 500 miles an hour to take anyone beyond the gravity of the earth into space.

    　　　　 D. There are many problems connected with space travel.

    　　 4. Which is the best title for this passage?

    　　　　 A. Weightlessness. Gravity and Strain Are All too Difficult to Understand

    　　　　 B. Gravity is the Enemy of Space Travel

    　　　　 C. Space Travel Problems

    　　　　 D. People Cannot Leave the Earth Because of the Air

    Children are great. However, being a parent to a child can be very challenging. In your child’s preschool years he is sure to test you to see what he can and can’t get away with. Ensuring your child behaves himself is easier said than done. But you can minimize(最小化)frustrations and enjoy every moment you have with your child by the following.

    Spend quality time with your child. Try putting off some work to spend time with your child. Play with him or read him a book. By spending quality time with him every day you are letting your child know that you are concerned about him.

    State your rules in black and white. At first, it may be tough for you to carry them out just because of your child’s too much crying, and you have to give in to him at times. But in the long term, by sticking to your rules, you are letting your child know what behaviour you will and will not bear.

    Punishment should be avoided if possible. It will deeply affect your child’s physical and mental health. It you want to correct his mis behavior, do it in a friendly way.

    You children copy their parents’ behavior. If you are trying to teach your child to always be kind to others, your behavior needs to suggest that. By being on your best behavior in front of your child you will set a wonderful example to him. Your child will only be this age once. Allow your child to make his own decisions. Let him make mistakes sometimes so he will learn to be more responsible for his actions.

    Another thing that you have to remember is to let your child understand that his actions always affect other people and his misbehavior is not the solution to his problem.

    By following those above, you are on your way to having a well-behaved child and getting along well with him.

    Title: How to raise 1._______

    I. Difficulty

    It is 2. ______to shape a kid.

    II.3. _______

    l Spare some time with your kid and let him know 4. _______.

    l Be consistent in carrying out 5. _______.

    l Correct your kid’s misbehavior in a friendly way rather than 6. _______.

    l Make yourself a good 7. ______ to your kid.

    l Give your kid 8. ______ to arrange his own life.

    l Help your kid know 9. _______ have an effect on others and his misbehavior makes no sense.

    III. 10. _______

    Your kid will behave himself and you will have a good relationship with him.

    阅读理解。
         It's perfectly normal for young children to suddenly decide they hate everything-even foods they loved
    yesterday. It's also common for them to go on what experts call food jags-that is, they want to eat the same
    few foods over and over again at every meal, while turning up their noses at anything new. "It's a fear of new
    things," says Nancy, Hudson, a researcher in University of California, Berkeley. "We think it's one of those
    quirks (怪癖) that humans probably developed to protect themselves as mankind came into this world. You
    don't try new things because you don't know if they're safe." Children like familiar things, whether they're their
    beds or their aftemoon tea,so most kids won't try new foods until they've been shown to them many times.
         Picky (挑剔的) eating can also be a child's way of showing his independence. This is why forcing a child
    to eat often makes things worse. Finally, it may seem like your child cannot sit still long enough to eat very
    much at one sitting because of his short attention. But children are generally good at getting what they need,
    even if it doesn't seem like much to you. In any case, you can try to keep your child at the table longer by
    making mealtime as calm and regular as possible, without too many distractions (分心的事物) like toys, TV,
    or pets.
    1. How many reasons does the writer mention in this passage to explain why children are mostly picky eaters?
    A. Three.
    B. Two.
    C. Four.
    D. One.
    2. What does the phrase "turning up their noses" underlined in Paragraph l mean?
    A. Accepting.
    B. Disliking.
    C. Putting their noses on.
    D. Fearing.
    3. Which statement is TRUE according to the passage?
    A. Only children like things which they are familiar with.
    B. Toys are not good for children.
    C. It seems that children like eating more when they have something they like in their hands.
    D. Make it a rule to let your child eat at the table when meal- time comes.
    4. According to the writer, one of the ways to have children eat new foods is _____.
    A. telling them stories while they're eating
    B. not giving them any food until they're very hungry
    C. letting them become familiar with the new foods
    D. explaining to them how useful the new foods are
