【题目】 Every day, the world uses about a thousand million tons of water. Water is a human right and everyone should have their share. Yet more than 700 million people around the world have trouble getting clean, safe water.

Treating(处理)wastewater is a good way to provide fresh water for us. And it also helps the environment by keeping waste out of rivers and oceans. 80% of wastewater around the world is not treated at all, and it is running into oceans. But now we have got the technology to treat and reuse the wastewater.

While 75% of our planet is covered with water, only 2% is fresh water—that comes from rivers, lakes, ice and snow. The rest, 98% of the water, is in seas and oceans. It is too salty to drink. Then desalination businesses come in. More than 19,000 factories have been built around the world, mostly in coastal(海岸的)countries. They process(加工)more than 92 million tons of salty water every day. But the technology they use requires a lot of energy.

Scientists are working to create a less costly technology. They want to produce 20 times more clean water and make sure everyone has enough. But for now, the world still faces each day with not having enough water for everyone.

1How many tons of water does the world use every day?

A.Over 700 million.B.About 1,000 million.

C.Only 10 million.D.Under 92 million.

2How does treating wastewater help the environment?

A.By letting waste run into oceans and rivers.

B.By putting waste into lakes.

C.By stopping waste running into rivers and oceans.

D.By sending waste to coastal countries.

3What does the underlined word “desalination” in Paragraph 3 mean?

A.远洋运输B.潮汐发电

C.海水淡化D.食盐销售

4At present, the technology to process water .

A.causes pollutionB.saves much water

C.wastes much moneyD.needs much energy

5What can we know about from the passage?

A.Thanks to the technology, people have enough clean water now.

B.75% of our planet is covered with water, and most is fresh water.

C.Though we have tried many ways, water problem is still serious.

D.Desalination companies can treat much wastewater every day.

【题目】 Qian Xuesen is known as “the father of China’s space program” and “the king of the rocket”. He was born in Shanghai on December 11th, 1911.

When he was 24 years old, Qian went to America for further study. After graduation, he worked in America for a few years, where his working conditions were better. In the early 1950s, he heard New China had been founded(成立)and there were few scientists like him in China. So he decided not to stay in America any longer. He succeeded in coming back to his motherland in 1955 though the American government tried to stop him.

In 1956, Qian Xuesen suggested setting up a special organization, which later became the leading organization for China’s rocket and air travel programs. In June 1964, China successfully created its first medium rocket(中型火箭). Qian also played an important role in developing China’s first man-made satellite(卫星). On April 24, 1970, “Dongfanghong-I” was successfully sent into the air.

Zhu Yilin, who was said to be the last student of Qian Xuesen, once said, “From Mr. Qian, I learned rich knowledge as well as the spirit and attitude that a scientist should have, especially his deep love for the motherland. Without that, he couldn’t have helped to develop science and technology when conditions in New China were too hard. Without that, he would not have made the great contribution(贡献)to rocket industry.”

Mr. Qian has been dead for ten years, but he will live in the memory of Chinese people forever.

1Why did Qian Xuesen decide to return to China?

A.Because he was not welcome in America in the 1950s.

B.Because New China was in need of scientists like him.

C.Because he could become well-known in China.

D.Because working conditions in China made it easier to develop rocket industry.

2When was “Dongfanghong-I” successfully sent into the air?.

A.In 1955.B.In 1956.C.In 1964.D.In 1970.

3What does Paragraph 3 mainly tell us?

A.The way Qian Xuesen tried to return to China.

B.The reason why a special organization was set up.

C.The role Qian Xuesen played in making the satellite.

D.The contribution Qian Xuesen has made to China.

4In Zhu Yilin’s opinion, what made Qian Xuesen work hard for China?

A.His attitude towards rocket industry.B.His rich knowledge.

C.His love for the motherland.D.His working experience.
