【題目】 When 4-year-old British Prince George started his first day of school in September, 2017, Chinese language was on his course.

And he wasn’t alone. According to a report in September, about 51 percent of UK parents want their children to learn Chinese, as it’s believed to be one of the most useful languages to know.

In fact, the popularity of Chinese drove the UK government to launch the Chinese Excellence Program in September last year. Its goal is to make at least 5, 000 British state middle school students speak Chinese well by 2020.

The language has become the second most spoken foreign language in the US, after only Spanish (西班牙語),with over 2. 1 million speakers, according to a survey.

Many US famous people such as Facebook founder (臉書創(chuàng)始人) Mark Zuckerberg and Obama’s daughter,Malia Obama, study Chinese as a second language.

So far, 67 countries and regions (地區(qū)) have included Chinese in their national course, so why are so many countries crazy about learning Chinese?

One reason could be that as China continues to develop quickly, Chinese is increasingly becoming a useful tool for people’s personal and professional growth. “I think everyone believes that China will be the next great superpower (超級大國)... even if it' s not a superpower like America. It still has an important influence in the future,” said Aisling.

McCaffrey from Canada, who studied at the Renmin University of China, “Learning Chinese is the best way to make sure that you can be part of that growth.”

This opinion was shared by former (前任的) British Prime Minister David Cameron, who urged(呼吁) British students to learn Chinese to “seal (抓住) tomorrow’s business deals” in 2013.

【1】Why do UK parents want their children to learn Chinese?

A.Chinese is on the course.B.Princess George starts to learn Chinese.

C.The UK government sets up the program.D.Chinese is one of the most useful languages.

【2】________asked British students to learn Chinese.

A.Malia ObamaB.David CameronC.Prince GeorgeD.Mark Zuckerberg

【3】Which of the following is NOT true according to the passage?

A.Aisling McCaffery is from Canada.

B.Learning Chinese is the best way to be famous.

C.There are more than 2.1 million Chinese speakers in the US.

D.67 countries and regions have included Chinese in their national course.

【4】What’s the best title of the passage?

A.The ways to learn Chinese well

B.The increasing number in learning Chinese

C.Why learning Chinese has risen around the world

D.The relationship between language and development

【題目】 I suddenly heard an elephant crying as though frightened. Looking down, I immediately recognized that something was wrong, and ran down to the edge of the near bank. There I saw Mashwe with her three-month-old calf struggling in the fast-rising water, and it was a life-and-death struggle. Her calf was floating and screaming with fear. Mashwe was as near to the far bank as she could get, holding her whole body against the rushing water, and keeping the calf pressed against her huge body. Every now and then the rushing water would sweep the calf away.

There was a sudden rise in the water and the calf was washed clean over the mother’s body and was gone. Mashwe turned quickly to reach it and pressed the calf with her head and trunk(象鼻) against the rocky bank. Then with a huge effort, she picked it up in her trunk and tried until she was able to place it on a narrow shelf of rock.

Just at this moment, she fell back into the river. If she were carried down, it would be certain death. I knew, as well as she did, that there was one spot(地點) where she could get up the bank, but it was on the other side from where she had put her calf.

While I was wondering what I could do next, I heard the sound of a mother’s love. Mashwe had crossed the river and got up the bank and was making her way back as fast as she could, roaring(吼叫) all the time, but to her calf it was music.

【1】The moment the author got down to the river bank he saw _______.

A.the calf was about to fall into the river

C.the calf was washed away by the rising water

【2】How did Mashwe manage to save her calf from the fast-flowing water?

A.By putting it on a safe spot.B.By pressing it against her body.

C.By taking it away with her.D.By carrying it on her back.

【3】How did the calf feel about the mother elephant’s roaring?

A.It was a great comfort.B.It was a sign of danger.

C.It was a call for help.D.It was a musical note.
