A thousand years ago, Hong Kong was covered by a  1 forest. As more and more people came to live in Hong Kong, these trees were 2 and burnt. Now there are only a few forests left and we call these 3, a small area covered with trees.

    Elephants, tigers and many 4 animals were living in the thick forest. Early farmers needed fire to keep themselves 5 in winter, to cook their food and to keep away the dangerous animals. They 6 rice and kept pigs and chickens in the valleys. They cut down the trees and burnt them. Elephants quickly disappeared 7 there was not enough food for them. So did most of the wolves and tigers. Monkeys and many other animals soon 8 in the same way.

    There are about 36 different animals living in Hong Kong now. One of the most interesting of Hong Kong's 9 is the barking deer. In Hong Kong the barking deer has only a real enemy human beings. There are now not 10 barking deer left. So it is important for people to protect wild animals.

    People sometimes like to read stories of dogs very much. They think that dogs are much cleverer than cats, sheep, cows or other animals in their homes.

    One of my close friends, Bob, has a very large police dog named Jack.  Every Sunday afternoon, Bob and Jack have a walk in the park nearby. Jack likes these walk very much.

    One Sunday afternoon, I paid a visit to my friend. I stayed there for a long time and my friend and I had much more talk with each other than ever before. Soon it was time for them to take a walk in the park. We forgot that. Jack became worried about it. He walked around the room several times and then sat down in front of me and looked at me. But I still paid no attention(注意) to him. I went on talking with my friend. At last, Jack could not wait any longer. He went out of the room and came back a few minutes later. He sat down in front of me again. But this time, he held my hat in his mouth. Suddenly, I understood what Jack meant and so did my friend.
