During the day, you spend a lot of time running, jumping, laughing, eating, and talking. You use up a lot of energy(能量) , and by the end of the day you’re tired. Sleep gives your body a chance to rest.
But your brain (大脑)and body are not completely at rest during sleep. While you sleep, your mind may think of the things that happened during the day. It keeps the important things in mind as memories(记忆). It also thinks about things you were worrying about, and you may wake up with answers to some of your problems.
You also grow while you sleep. The thing called "human growth hormone (荷尔蒙)" in the body helps you grow during sleep. This growth hormone also helps the body to repair itself.
Sleep helps your body to conserve energy too. You use up a lot of energy during your daily activities. But when you sleep, your body temperature falls, and your "metabolism" (新陈代谢) slows down. You are still using some energy, but much less than when you are awake and active.
Have you ever stayed up past your bedtime? Did you have difficulty getting up the next morning? Maybe you had problems seeing clearly or you cannot think clearly. That was your body’s way of saying, "I need sleep！" A lack ( 缺乏) of sleep can stop your body and mind from working correctly.
【小题1】What does "human growth hormone" do while people sleep?

One day, I heard an American boy say to a Chinese girl student, “You speak very good English.” But the girl answered, “No, no. My English is very poor.” The foreigner was quite   1   at the answer. Thinking he had not made    2   understood or the girl had not   3   him clearly, he said, “Yes, indeed, you speak very well.”   4   the girl still kept saying, “No.” In the end the American boy could not understand and didn’t know   5   to say.
What’s wrong with the girl’s answer? She didn’t   6  a compliment (恭维) in the same way as the American people do. She should answer, “Thank you” instead of “No”. She   7  understood what the American boy had said, but she thought she should be modest. In the   8  , people will feel proud and 9   when they are praised . So if someone says the   10   you have cooked are very delicious, you should say, “Thank you.”
In our country we think being modest is a virtue (美德) and being proud is a bad thing , but in my opinion, being confident does not   11  being proud, so sometimes you should be confident   12  being modest.
   13  you are modest and say, “No, I’m afraid I can’t do it well”, while working in a western country, the others may think that you really cannot do it. If you often say “No”, you will certainly be looked down upon by  14 . When asking for a job, if one says something like “Yes, I can certainly do it” instead of “Let me have a try”, he or she will   15   get it. So in the west, you should be brave to show your self-confidence.

Happiness is for everyone. You don’t need to care about those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and a lot of money and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.
In fact, happiness is always around you if you put your heart into it. When you are in trouble at school, your friends will help you; when you study hard at your lessons, your parents are always taking good care of your life and your health; when you get success, your friends will say congratulations to you; when you do something wrong, people around you will help you to correct it. And when you do something good to others, you will feel happy, too. All these are your happiness. If you notice a bit of them, you can see that happiness is always around you.
Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something else that can’t be bought with money. When you meet with difficulties, you can say loudly you are very happy, because you have more chances to challenge(向…挑战)yourself. So you can not always say you are poor and you have bad luck. As the saying goes, life is like a revolving(旋转)door. When it closes, it also opens. If you take every chance you get, you can be a happy and lucky person.
