三、阅读理解
On Thursday, Uncle Max called Tom, “Tom, I was wondering if you’d like to go camping with me this weekend.”
Tom said, “I’m not sure, Uncle Max. Why do you want to go camping ”
“Well, I am going to write a story about endangered animals for the paper. I think it will help with my writing if I go up to the mountains. I just won’t get a feel for nature if I stay in my apartment in the city.”
“Sure, I’ll go with you,” Tom said, “Don’t forget your camera.”
“I won’t.” Uncle Max smiled.
On Saturday morning, Uncle Max and Tom got an early start. After they put up the tent, they sat down to relax. “It seems hard to believe that animals could be in danger in place as beautiful as this,” Tom said.
“You’re right,” Uncle Max said. “That’s why my story is so important. In the past, uncontrolled hunting (捕猎) was the main reason for animal extinction (灭绝). But now, many wild animals in our country are protected by laws. These laws limit hunting.”
“Why are some animals in danger now ” Tom asked.
“Some of their homes are destroyed (破坏) by pollution. Also, the land is used for homes, farms, and highways. That leaves fewer places for animals to live. So some land has to be left as national parks for wildlife,” said Uncle Max.
“I’m glad you invited me,” Tom said. “I just didn’t know how much animals depend on us. I think your story will help all of us.”
21．Why did Uncle Max go camping ________
A．To relax. B．To exercise. C．To help with his writing. D．To take photos of nature.
22．What does the underlined word “limit” in Paragraph 7 mean in Chinese ________
A．限制 B．接受 C．解决 D．鼓励
23．In Uncle Max’s opinion, why are some animals in danger now ________
A．Because people hunt them a lot. B．Because they can’t find enough food.
C．Because their health is destroyed by pollution. D．Because there are fewer places for them to live.
24．What did Tom think of the story Uncle Max would write ________
A．Perfect. B．Helpful. C．Successful. D．Humorous.
25．What’s the writer’s purpose of writing this article ________
A．To show how to write a story. B．To tell how to build national parks.
C．To advise people to go camping on weekends. D．To encourage us to protect endangered animals.
Pituco is a special dog from Brazil. Why do I say so Because he can go shopping all by himself. Every day, Pituco goes to Agro Pet to get his food. That makes him popular.
