Question

【題目】 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（處理）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.遠(yuǎn)洋運(yùn)輸B.潮汐發(fā)電

C.海水淡化D.食鹽銷(xiāo)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】

本文介紹的是：全世界對(duì)水的需求很高，海水凈化工藝應(yīng)時(shí)而生，為保護(hù)環(huán)境做出貢獻(xiàn)。但是水資源短缺的現(xiàn)狀仍然沒(méi)有改變。

【1】細(xì)節(jié)理解題。根據(jù)第一段中the world uses about a thousand million tons of water可知“全世界的人們每天使用大約1,000 百萬(wàn)噸水”。故選B項(xiàng)。

【2】細(xì)節(jié)理解題。根據(jù)第二段中it also helps the environment by keeping waste out of rivers and oceans“它也通過(guò)減少污染進(jìn)入河流和大海來(lái)保護(hù)環(huán)境”可知選C項(xiàng)。

【3】詞義猜測(cè)題。根據(jù)It is too salty to drink. “水太咸了不能喝”，所以Then desalination businesses come in“海水淡化產(chǎn)業(yè)產(chǎn)生了”。故選C項(xiàng)。

【4】細(xì)節(jié)理解題。根據(jù)倒數(shù)第二段中the technology they use requires a lot of energy可知這項(xiàng)技術(shù)需要消耗大量的能源。故選D項(xiàng)。

【5】推理判斷題。根據(jù)文章最后the world still faces each day with not having enough water for everyone可知現(xiàn)在全世界人們還面臨著缺水的現(xiàn)狀，故A項(xiàng)不正確；根據(jù)only 2% is fresh water 可知B項(xiàng)不正確；根據(jù)They process（加工）more than 92 million tons of salty water every day可知這項(xiàng)工程每天只能處理9200萬(wàn)噸海水，故D項(xiàng)不正確。故選C項(xiàng)。
