Monarch butterfly is a beautiful insect.
Monarch butterfly is insect, it is beautiful, every year , Milli0ns of Monarch butterflies fly from Canada to Mexico ,the way is about 4000 km. they fly 45km every day .Why do they go to Mexico? Because , Canada is too cold ,they are live in Mexico six months ,from April to October . And then, new Monarch butterflies are fly from Mexico to Canada, they are not “old” Monarch butterflies, because Monarch butterflies lay their eggs and the they die.
In the Canada, new Monarch butterflies lay eggs ,and then die, the egg change to the Monarch butterfly caterpillar, the Monarch butterfly caterpillar change to the Monarch butterfly chrysalis , the Monarch butterfly chrysalis grow to the adult Monarch butterfly, the adult Monarch butterfly lay egg and then die ……
I have a question : How do the Monarch butterfly know the way? Maybe only Monarch butterflies can answer this questions .

Panda—the National Treasure
Panda is one of the scarcest animals.People in the world like it very much.There used to be many pandas in China long ago.As the balance of nature was destroyed and the weather was getting warmer and warmer,pandas became less.But at present,the number of pandas is increasing year by year.There are now so many pandas that some are being sent to other countries so that people there can enjoy them.
Nowadays,the biggest nature park for panda in China is in Sichuan.There is a research centre for nature and wild life there.Scientists hope that one day they will have enough pandas to be set free and let them live in the wild again.
Many wild animals are facing the danger of extinction, because the environment that they are living in has changed greatly.
For example, with the developmet of cities, the using of insecticide and serious pollution, their living areas have become narrowcr and narrower.
Many of the wild animals, now are confronted with food crisis. At the same time, man is killing off species just for getting their fur, skin, horns, teeth and meat.
In order to protect our resources of ecology, people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty. There fore, measures of the following should be taken: pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life, reserves.
Only if we human beings take some drastic measures can wild animals be preserved.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or planton the danger list. Slowly, the number of some animals in danger is growing.
Once there was a famous masician in our country. His name was Gongsun YI. He liked to play the lute very much. One day he saw a cow eating grass. He was very happy and began to play the lute to the cow. The music
was very pleasant, but the cow still ate grass without listening to it.
Gongsun Yi went away unhappily. He wondered why the cow didnot listen to the nice music. In fact the cow could not understand music. Gongsun Yi just played the music to the wrong audience.
