When people think of tigers, words like" strong" and " dangerous" come into their mind. But now, the big animal is calling for our help. There were once eight kinds of tigers in the world, but three died out during last century. In the past 70 years, the number of Siberian tigers has gone from as many as 300 to somewhere between 18 and 22.

   World Wildlife Fund started a programme. It is about to put an end to tiger poaching(非法狩猎) and save wild tigers. China, together with 12 other countries, has joined in. The aim is to double the number of wild tigers in the next ten years.

According to the research by Chinese officers and WWF, the Siberian tiger is already one of the planet's most endangered animals. "If the government doesn't do anything, it's quite possible that there will be no more Siberian tigers in China in 10 to 20 years." said Zhu Chunquan, director at WWF Beijing office.

    Wild animals such as deer and wild bears are tigers' main food. The poaching of these animals is the greatest danger to tigers. Another one is the trap(陷阱). "Volunteers from WWF remove traps every year, but we cannot clear all the traps ourselves," Zhu said. The most important thing people can do is to save the animals tigers eat." To protect the tigers, we need to call on more people to stop hunting wild animals."

In the end of the movie, he reveals his identity to the whole world in an interview.

On Saturday morning, every boy in town was happy, except Tom Sawyer. Tom's aunt said he had to paint the fence(围栏). It was thirty yards(码) long and three yards high! When he was working, some boys came along and made fun of him. 

Ben was the first one who came happily with an apple in his hand. 

"I'm going swimming," said Ben. "Do you want to come? Oh, you have to work, don't you?"

Tom got a little angry, but soon he had a wonderful idea. 

"Work?" he said. "I don't think this is work. It's fun. Does a boy get a chance like this every day?"

Ben thought about this. He was watching Tom's every move and was getting more and more interested. 

After a while, he said, "Tom, will you let me do some painting?"

"No way. You see. Aunt Polly wants it to be done properly. I'm the only one that can do it right."

"Oh, please, Tom," begged(恳求) Ben." I'll be really careful. Let me try! I'll give you my apple in return."

"Well, all right, Ben," said Tom. "But you must be careful."

He gave Ben his brush with worry on his face but joy in his heart. He started to eat Ben's apple. 

All day, boys passed by and wanted to paint. When Ben got tired, Billy began to paint. He gave Tom his favorite kite. Then Johnny gave him twelve marbles(玻璃球), and so on. 

That afternoon, Tom got many toys, and the fence got three coats of paint. Aunt Polly was so pleased when she saw the painted fence that she gave Tom a large cake!
