Hong Kong, these trees were cut down and burnt. Now there is 11 forest left, though there are still some small
areas(地方)covered with trees. We call these woods.

keep away the dangerous animals. Elephants quickly disappeared because there was not enough food for them.
16 did most of the wolves and tigers. Monkeys and many other animals soon 17 in the same way.
You might think that there are no longer any animals in Hong Kong 18 in the zoos. There are still about 36
different animals 19 there. One of the most interesting animals of Hong Kong is the barking deer. These are
beautiful little animals with a rich brown coat and a white patch(斑点)under the tail. They look like deer but they
are much like a barking dog. In Hong Kong the barking deer has only a real enemy— 20 . People hunt these
little animals though it is illegal(违法的). There are now not many barking deer left. So it is important for people
to care for wild animals.
