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.

Who do you admire(崇拜)?Different people may have different ideas.
If you’re a sports fan, perhaps the person you admire most is a great basketball player, and Yao Ming is probably the one in your mind. If you study music or play an instrument, perhaps the person you admire most is gifted musician like Mozart, who began to write beautiful music at a very young age. Or maybe you admire great scientists, for example, Yuan Longping.
We have many reasons to admire famous people and we often give much of our respect to them. However, we shouldn’t neglect those who are common, such as nurses, train drivers, firemen, cleaners and so on. They may be working in a corner of the world without being noticed, but all these people spend their working days serving the public. They show great dedication(奉献).However, what they do is often unnoticed by us. Have you ever thought of what our life will be like if they stop working?
So next time when you appreciate famous people, don’t forget those who are common around you.

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 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.
