     Animals are people's friends.  But many wild animals are facing the danger of dying out, because the

environment that they are living in has changed greatly. For example, their living area has become smaller

and smaller because of pollution and the development of cities. They have no room to live in except the

zoo.  And many of the wild animals now can't find enough food to eat: At the same time, man is killing off

animals just for getting their fur, teeth and meat.

     People should realize how serious the situation is and something should be done to protect the animals.

We should set up some nature reserves so that animals can live freely. And people shouldn't be allowed

to kill the endangered animals. We should also do something to make our world cleaner. Fresh air, clean

water and green grass are all important for animals. The death of the endangered animals will bring a

disaster to human beings.

(      )1. The number of the wild animals is smaller now.

(      )2. With the development of the cities, the living area for the animals has become smaller and smaller.

(      )3. Man is killing off animals just for fun.

(      )4. The wild animals are very safe now, because we have found a lot of useful methods(方法) to save them.

( )5. All of us should try our best to protect the animals.
