Question

【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.

【1】How 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.

【2】How 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.

【3】What 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

【4】At present, the technology to process water .

A.causes pollutionB.saves much water

C.wastes much moneyD.needs much energy

【5】What 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.

Answer 1

【答案】

【1】B

【2】C

【3】C

【4】D

【5】C

【解析】

本文介绍的是：全世界对水的需求很高，海水净化工艺应时而生，为保护环境做出贡献。但是水资源短缺的现状仍然没有改变。

【1】细节理解题。根据第一段中the world uses about a thousand million tons of water可知“全世界的人们每天使用大约1,000 百万吨水”。故选B项。

【2】细节理解题。根据第二段中it also helps the environment by keeping waste out of rivers and oceans“它也通过减少污染进入河流和大海来保护环境”可知选C项。

【3】词义猜测题。根据It is too salty to drink. “水太咸了不能喝”，所以Then desalination businesses come in“海水淡化产业产生了”。故选C项。

【4】细节理解题。根据倒数第二段中the technology they use requires a lot of energy可知这项技术需要消耗大量的能源。故选D项。

【5】推理判断题。根据文章最后the world still faces each day with not having enough water for everyone可知现在全世界人们还面临着缺水的现状，故A项不正确；根据only 2% is fresh water 可知B项不正确；根据They process（加工）more than 92 million tons of salty water every day可知这项工程每天只能处理9200万吨海水，故D项不正确。故选C项。
