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

　　Some birds like eating locusts (蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). 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 to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This is because they have the colors much like the trees.

Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体)when it faces danger. While the liquid spreads over (散开), its enemies (敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.

Dear Annie,

I have never written a letter to a newspaper before, I have just never felt the need to do such a thing. I have always felt I was quite able to do everything by myself. But now I know I was wrong.

Sometimes you really need help in life, I guess. And that’s why I’m writing this letter to you.

I have a happy family. I love my children and they love me . I’m a mother of three children. I know well how to bring up (带大)children, and two of them are already over twenty, so it is nothing new for me.

But now I have a serious problem:the Internet problem. My little son is just sixteen, and I feel he should do a lot of homework now , but he doesn’t seem to be interested in it . He can happily spend six or eight hours at a time on the Tnternet every day , He chats with pelple that he has never met before , but speaks little to us .He does lots of useless things on the Internet. And he sees red if you ask him to do his homework.

I just want him to be a good student . Now he seldomdoes his lessons at home. I’m afraid he will drop behind in his class soon. His father is a doctor , a very kind man . He never seems to be afraid of his father.

What can I do ?And don’t tell to talk to him. We’ve tried that and it didn’t work. But this is really a big problem in our family. I have tried everything I can think of . I

wonder how the Internet is so attractive(有吸引力的).You’re my last hope. Please tell me what I can do!

Yours,

Ellen Smith
