Do you know why different animals or pests (昆虫) have their special colors? Their 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 the animals 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. 36.

I went to the Chinatown market in London last Sunday. The first thing I did was to go to one of the Chinese green grocers? shops. As soon as I entered the shop, I smelt mixtures of Chinese spices and saw the new season?s fruits. My son wanted a bag of sweets, so we the shop next door which sells many kinds of candy.
There is a lot of noise in the Chinatown market and you will see many tourists too. There are a lot of cars and trucks that never stop beeping. While people are loading and unloading their goods, most of them have their cars and trucks parked in the middle of the road. This causes great inconvenience for other drivers. Can you imagine that?
After we had done all our shopping, my son and I went to a restaurant for lunch. We enjoyed our meal very much. But the shopping made us both very tired in the end. We headed down the road to catch
our bus home. My son and I enjoyed riding in the bus. We also enjoyed looking at different buildings and people walking by dressed in fancy outfits. Although Chinatown can be a busy place to shop in, I do enjoy going there now and then. I can buy some of my necessities, and I can also look and browse around the other shops and department stores where I can indulge (使沉迷) myself with some nice things. Chinatown is located in the heart of central London, where you can find tons of shops and other places to amuse you. And for me, I certainly don?t mind going back there again soon. 39.

When a storm is coming, most people leave the area as quickly as possible and head for safety. But there are a few people who will get into their cars and go straight for the center of the storm. These people are willing to risk being killed by floods or 100-kilometre-an-hour winds for the excitement of watching the storm close up.
“Storm chasing” is becoming an increasingly popular hobby, especially in the Midwest of the United States, where there are frequent storms between March and July. A storm chaser begins the day by checking the Internet for the latest weather reports, and then drives up to 1,000 kilometers to where the storm will be and waits for it to develop.
Although anyone can do it, storm chasing is extremely dangerous. The power of a big storm can throw a cow into the air or destroy a whole house in seconds. Storm chasers are also often hurt in accidents caused by driving in a heavy rain. If you are a beginner, it is much safer to join a group for storm chasing vacations during the storm season.
Even then, storm chasing is not all adventure or excitement. “Storm chasing is 95% driving,” says Daniel Lynch, who spends most of his summer storm chasing. Sometimes you can sit round for hours waiting for something to happen, and all you get is blue sky and a few light showers.”
However, for storm chasers, it is all worth it. “When you get close to a storm, it is the most exciting sight you will ever see in your life,” says Jasper Morley. “Every storm is an example of the power of nature. It is the greatest show on Earth.”

C. wait patiently for the storm to develop D. collect information about a coming storm
