四、书面表达
【答案】例文：
A few restaurants still have some wild animals as delicious food on the table. I think there are many endangered animals in the world, such as tigers and pandas. When farmers cut down trees, tigers can no longer hide and hunt. Many tigers are killed by people who want to sell their fur for money. And there are few places where pandas can live. We are not alone in the world. We human beings could not live without all the plants and animals around us. So protecting wildlife animals is very important. We must take measures to keep plants from being destroyed and stop animals from being killed. If each of us can plant a tree and build a birdhouse, the world will be more beautiful. It is very easy but useful. Only if we human beings take some measures can wild animals be preserved.
