Question

    The world uses about a thousand million (百万) tons of water a day. 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 waste water 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 waste water 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 waste water. While 75% of our planet is covered with water, only about 2% is freshwater- 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 19000 factories have been built around the world, mostly in coastal countries. They process (加工) more than 92 million tons of 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 people have trouble in getting clean water around the world?

A.Under 700 million. B.Over 700 million. C.About 92 million.

2.Treating waste water helps the environment by________.

A.storing waste in ice and snow

B.letting waste run into oceans

C.keeping waste out of rivers and oceans

3.What does the underlined word "desalination" in Paragraph 3 mean?

A.远洋运输 B.食盐销售 C.海水淡化

4.At present, the technology to process water________.

A.needs much energy B.saves much money C.satisfies everyone

5.What can we infer from the last paragraph?

A.Everyone has enough clean water.

B.The water problem is still serious.

C.Our planet is covered with water.

5.B

【解析】

“水是生命之源”，我们的生活离不开水。但地球上的水资源是有限的，全世界很多地方的人们仍然没有办法获得干净、安全的水。现在我们有了一项新的技术，可以处理和再利用废水，但它需要大量的能源，因此科学家们正在努力创造一种成本更低的技术。

1.

细节理解题。根据第一段中“Yet more than 700 million people around the world have trouble getting clean, safe water.”可知，全世界有7亿多人难以获得干净、安全的水。故选B。

2.

细节理解题。根据第二段中“Treating waste water is a good way to provide fresh water for us. And it also helps the environment by keeping waste out of rivers and oceans.”可知，处理废水是为我们提供淡水的好方法，它还有助于保护环境，使废物远离河流和海洋。故选C。

3.

词义猜测题。根据单词所在的上下文语境“The rest, 98% of the water, is in seas and oceans. It is too salty to drink. Then desalination businesses come in.”可知，地球上98%的水在海洋里，是咸水不能喝，然后下文“More than 19,000 factories have been built around the world”有很多工厂被建。由此可推测desalination的意思应该是“海水淡化”，故选C。

4.

细节理解题。根据第二段中“But the technology they use requires a lot of energy.”可知，现在处理海水的技术需要大量的能量。故选A。

5.

推理判断题。A：每个人都有足够的干净的水。B：水的问题仍然很严重。C：我们的星球被水覆盖着。根据短文最后一句话“But for now, the world still faces each day with not having enough water for everyone.”可知，现在，世界每天仍然面临着没有足够的水供每个人使用。由此可知现在水问题仍然非常严重，故选B。
