A thousand years ago Hong Kong was covered by a thick forest. As more and more people came to 　31　 in Hong Kong, these trees were cut down and burnt. Now there is　32　 forest left, though there are still some small areas covered with trees. We call these woods.
　　Elephants, tigers and many　33　 animals were living in the thick forest. When people came to live in Hong Kong, the　34　 began to die out. Early farmers grew rice and　35　 pigs and chickens in the valleys. They cut down the trees and burnt them. They needed　36　 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. 　37　 did most of the wolves and tigers. Monkeys and many other animals soon　38　 in the same way.
　　You might think that there are no longer any animals in Hong Kong　39　 in the zoos. But there are still about 36 different animals　40　 there. One of the most interesting of Hong Kong's animals is the barking deer. These are beautiful little animals　41　 a rich brown coat and a white patch (补丁) under the tail. They look like deer but they are much smaller. They are less than two feet　42　. They make a noise rather like a dog　43　. In Hong Kong the barking deer has only a real enemy--　44　. People hunt these little animals though it is illegal (违法的). There are now not many barking deer left. So it is important　45　 people to protect wild animals.

A new school term begins, Is anything new at your school? Sichuan students are getting an extra (额外的)hour to sleep in the morning.
This year, Sichuan schools decided that students should start classes later. This should help them feel less tired, For Junior high schools, the first classes will begin no earlier than 8:30 am.
The changes have made students happy.
Liu Xian, 15, said his class was excited by the news on the first day of school. “It’s so good we can get up later!” said Liu.
Liu studies in Chengdu No.4 Middle School. He used to get up at 6:40 am. Now he can get up at 7:40 am because class doesn’t start until 8:40 am.
Wu Hongli, 15, said the new timetable is good for her health. “I used to drink coffee every night or I would feel to sleepy to finish my homework, ”said Wu. “Now I can finish it without coffee.”She used to get up at 6:30 am. Now she can get up at 7:30 am.
Wu Hongli’s mother was happy, too. She thought more sleep would help her daughter grow taller.
But some parents worried that more sleep would mean less learning. There used to be five classes in the morning. Now there are only four.
Many teachers, though, say the changes will help students learn better.
“Students used to doze(瞌睡)for the first two classes in the morning,”said Wu Zongping, an English teacher at Chendu No.12 Middle School. “But now they look fine and they learn much better than before.”
