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.

Don’t you want to go to school? You could tell your parents you’re ill. But last Monday, students from Shanghai and Zhejiang had an even better excuse: a typhoon(台风)!
Typhoon Khanun hit East China on September 11. In Shanghai, all the school were closed the next day, Monday.
It was the first time that Shanghai had to close schools because of bad weather.
But some students still came to school that day. “ I didn’t get the notice that the school was closing,” said Shen Sheng, a Junior 2 student from Shanghai Aiguo School. “ But it was nice that we could play in school rather than study.”
The school kept Shen and other 20 students safe inside and let them play sports like table tennis.
But the storm wasn’t all fun games. Typhoon Khanun killed 14 people. In Zhejiang, it damaged about 8,000 houses. More than one million people had to be taken to safer places.
Every year, typhoons hit different places around the world. Most happen in July, August and September. This year 15 typhoons hit China. Khanun was the strongest. Typhoons bring strong winds and rains. The winds can blow away houses and cars. The rains are bad for farmers’ fields.
