I think animals are our friends. I like animals very much.
Once my mother bought a gold fish for me as a gift. It looked very beautiful. I liked it very much. I put it in a big bowl and fed it every day. I thought I should try my best to look after it. But one day, I found it was dead. It made me very sad. My mother said that it was too full because I fed it too much.
From then on, I realized I should learn more about the habits of small animals in order to care for them well.

The Search-for-Lost-Birds list has come to public attention recently. It lists ten kinds of birds that have not been seen in the wild for at least fifteen years. The list is calling on people to search for the rarest （最珍稀的） birds on Earth.

This year, four expeditions （考察队） are planning to find eight kinds of birds. If any of these lost birds are found, ways can be found to protect them and help their populations grow. This has happened with birds like the Madagascar pochard. The number of this once-lost kind of bird is now increasing.

Ⅳ.任务型阅读
阅读下面短文，根据短文内容，完成下列各题。
Eleven countries are building a great wall of trees across Africa. It is called the Great Green Wall. The aim is to bring life to the dry lands and help to fight the bad environment.
The wall is 8 000 kilometers long and 15 kilometers wide. It covers from Senegal in the west to Djibouti in the east, on the south of the Sahara Desert （撒哈拉沙漠）. So far, Senegal has made the best progress by planting about 11 000 000 trees.
Many years ago, there were few trees in that area and the winds used to be very strong. It was harmful to the fields. Also, there was little rain, so few plants could grow and many people went hungry. Since the tree planting project started, the trees have provided food for the local people and increased the wetness （湿度） of the air. Little by little, there appeared green fields for people to grow plants.
The project which began in 2007 is supposed to cost a total of 8 000 000 000 dollars. Many countries are trying their best to help to continue the planting. So we will be able to see the whole green wall across Africa in the near future!
