Mrs. Ball had a son. His name was Mick. She 　26　him very much and as（因为）he was not a 　27　child, she was always afraid that he might 　28　ill. 　29　she usually took him to see the best 　30　 in the town four times a year and asked the doctor to look 　31　the son.
　  During one of these 　32　, the doctor gave Mick all kinds of tests(检查) and then said to him, “Do you have any trouble with your nose or ears ?” Mick 　33　for a second and then answered, “Yes, I 　34 _.”
　 Mrs. Ball was very 　35　. “But I’m sure you have 　36　told me that, Mick!” she said worriedly. “Oh, really?” said the doctor 　37　. “And what trouble do you have 　38　your nose and ears, my boy?” “Well,” answered Mick. “I always have trouble with them when I’m  39　my sweater off, 　40　 the collar (领子) is very tight (紧的).”

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.

As everyone knows, there are many 　16　 of transportation in the world, like bicycles, buses, ships, trains and 　17　 .
If you are in big  18　like Shanghai or Beijing, maybe you get to school   19  a subway or you have to 　20　 to school because you live in a mountain village. Here I am just trying to say something about　21　 .
Ten years　22　, bicycles were very　23　in most villages.  24　 family had one or two of bicycles. Children got to school by bicycle; 　25　 rode bicycles to go shopping. Then motorcycles (摩托车)   26  to become popular. People no longer rode bicycles because motorcycles ran   27  faster.  But now, in some countries，bicycles are highly suggested
  28  the main means of transportation. They think buses, cars and motorcycles pollute(污染) the air but bicycles   29  . So, to live a low-carbon life,   30  a bike is a good way.
