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?

Do you know why different animals or pests have their special colors? Colors in them seem to be used mainly to protect themselves.

Some birds like eating locusts. but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.

If you study the animal life, you'll find the main use of coloring is protecting themselves. Bears, lions and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colors much like the tree.

Have you ever noticed an even more strange act? A kind of fish in the sea can send out a kind of very black liquid when it faces danger. While the liquid spread over, the enemies cannot find it. And it immediately swims away. So it has lived up to now though it isn't strong at all.

Last month when I was taking part in a US college interview, I was asked, “ what makes you special ? ” In fact I had answered questions likes this many times since I decided to go to college in the US .college paid special attention to different achievement . For example, a person who is very good at math can go to a famous college but also can be a good football player .
This experience made me think again that I must try to find where my own interests might lead me . To be honest, it was not easy . However, I never felt sorry to choose this way because it helped me understand myself . If I took the College Entrance Examination,as we call it gaokao in China, it could never possibly do .
When I entered high school, I took gaokao seriously because it seemed to me a great way to show how good at my lessons . However,as I grew older, I realized gaokao did make me work hard at my lessons, but the pressure also pushed many other activities out of my life, like guitar―playing . Although I had no time for it, I will still get to it in the future .
No doubt, gaokao provides a way of choosing those who are successful in their studies . But it is really important for all of us to rethink what “ talent ” really is today . This is because we now live in a world in which all of our other human qualities ( 品质）are needed for success, not just the high grade .
Ken Robinson once said, “ the society depends on different kinds of talents . ”  However, gaokao pays too attention  to a person’s grades but little to his other qualities. And it is these qualities that makes life colorful and fun .
As high school students, we can not change the present situation of eduction, but we are always free to think outside of the box . Although good school grade is still useful, I hope one day we will see our education also welcomes the amazing possibilities in different people .
