A thousand years age Hong Kong was covered by a thick forest. As more and more people came to 1 in Hong Kong, these trees were cut down and burnt. Now there is 2 forest left, though there are still some
small areas covered in trees. We call these woods.
Elephants, tigers and many 3 animals were living in the thick forest. When people came to live in Hong
Kong, the 4 began to die out. Early farmers grew rice and 5 pigs and chickens in the valleys. They cut
down the trees and burnt them. They needed 6 to keep themselves warm in winter, to cook their food and to keep away the dangerous animals. Elephants quickly disappeared because there was not enough food
for them.  7 did most of the wolves and tigers. Monkeys and many other animals soon 8 in the same way.
You might think that there are no longer any animals in Hong Kong 9 in the zoos. But there are still about
36 different animals 10 there. One of the most interesting of Hong Kong's animals is the barking deer.
These are beautiful little animals 11 a rich brown coat and a white patch（補(bǔ)釘） under the tail. They
look like deer but they are much smaller. They are less than two feel 12 . They make a noise rather like a
dog 13 . In Hong Kong the barking deer has only a real enemy （敵人）――14 . People hunt these little animals though it is illegal（違法的）. There are now not many barking deer left. So it is important 15
people to protect wild animals.

     What should we do to keep healthy? One important rule is to exercise    1   . The Fang family try to exercise
every day. Mr Fang    2    exercise in the morning because he must get to work at exactly seven o'clock. But he
runs every evening. He walks a lot,    3   . He walks to school every day, and after school he    4    different
sports with his friends. Mr Fang goes to a yoga (瑜加功) class    5   .
     But it wasn't    6    this way. Last year Mr and Mrs Fang used to (過(guò)去常常)    7    everywhere in their car,
even to the drugstore (藥店) two blocks (街區(qū)) away. They thought they had to use the car all the time. They
wouldn't walk.
