53天天练系列答案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.

Both the young and the old may feel lonely. A three-year-old child will feel lonely when it is left alone, and an old man over eighty years old is often afraid to live alone, too.
Some people feel lonely because they may not have enough time to make friends. Not only the quiet, shy people may feel lonely. Some people are active and outgoing, but they are sometimes afraid to talk and make friends with others. They always try to hold other people away from them. They may seem to have lots of friends, but inside they are hurting.
Are you lonely? If your answer is “yes”, you may need to work hard enough! Here are some tips to think about:
To be wanted and needed is a big answer to loneliness. Is there any way you can help other people? Try to do something helpful for others even if you are very busy. By helping other people, we find friends and lose loneliness.
Do you have an interest or hobby? Find a group of people with this interest and join them.
Live in the real world! The world on the Internet is not a real world and it is very different from the real life. The students asleep in class are mostly those who often surf the net through the night. As a result, they’ll get lost in the real world.
Don’t wait for someone to phone, or write, or email you, you call them. And if they seem too busy, it doesn’t mean you are not welcome. Try another time!
When you’ve done anything wrong to other people, don’t be too proud to say sorry. You must do that even if you find it hard to open your mouth.
