Do you know why different animals or insects have their special colors? Colors are used mainly to protect themselves.

Why can’t some birds easily catch locusts（蝗虫）? 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 autumn comes, locusts change to the same brown color as crops have. Some other insects with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives in the day and appear only at night.

If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals can’t be easily seen by hunters. This is because they have the colors much like the trees.

Have you ever noticed an even more strange thing? A kind of fish in the sea can send out black liquid when it faces danger. While the liquid spreads over, its enemies can’t find it. And it quickly swims away. So it has lived up to now though it is not strong at all.

What to do if you don't feel popular?
● Try to take part in activities. Call your friends. Plan to do something. The worst feeling is staying home alone, because it makes you feel even more lonely.
● Try to make new friends. Choose friends carefully, not just because you think they're popular. And remember, making good friends takes time. Choosing a popular person to be friends with is okay, if they are nice.
● Be yourself (保持独立). If you want to become friends with someone who's popular, don't make yourself into someone you are not just to impress that person.
● Be nice. Be friendly. Be outgoing (开朗的). But don't overdo it! Talk to trusted friends if you are feeling really bad. Or you might want to write it down in a journal (期刊) or diary.
● Do something special for yourself. You could take pictures of your friends, or collect their school pictures, and take a collage (拼贴画) to hang on your wall. This will remind (提醒) you, when you are feeling unpopular, that you really do have friends.
● Think up your own ideas. These suggestions might not work for everyone.
What to do if you have a problem with your teacher?
● Talk to your parents, or another adult who will listen to you and perhaps can help. Talk to your friends. Maybe they have had problems with the same teacher, too.
● Don't give the teacher a reason to have problems with you. Do your work, complete your task, attend the class seriously and take notes. Maybe you just need to give the teacher a chance (机会).
● Try to find out what the problem is.
● Talk to the teacher if you feel comfortable doing this. Don't be nasty (闹别扭的), but express your concerns (关心). Listen to the teacher, as well.
● Just accept the fact that you're not going to love all your teachers.
