Question

【題目】 If you know a bottle of water has been recycled from urine (尿液), will you drink it? Chinese astronauts have done so.

China National Space Administration(CNSA)says it uses a high-tech machine to recycle wastewater. The machine will recycle everything from sweat, the water for washing hands, shower water, water used for brushing teeth, and even urine, to make drinking water.

It saves CNSA millions of YMB each year. At present, each CNSA astronaut uses about 4.4 liters of water every day. It costs about ￥150 million a year to transport water up to space.

The urine recycling system is needed for astronaut stations because it won’t have to ship up as much water to the station by space shuttles or rockets. Besides, it’s important as the space station is about to expand from three people living on board to more.

The recycling system was brought up to the space station last August by space shuttles. The three-man crew stood holding their drinks and congratulated engineers in CNSA center that worked on the system.

“This is something that has been the stuff of science work,” astronaut Chen Dong said before taking a small mouthful. “The taste is well worth trying.”

Is the water clean? Scientists say the wastewater will go through a very complicated (復雜的) process. For example, different chemicals will be put in the wastewater; the water will be heated to 130C to get rid of bacteria. The recycled water is thousands of times better than the water from a city tap, scientists say.

【1】What can the water recycled from urine be used for?

A.Drinking.

【2】Why is a high-tech machine to recycle wastewater needed on space stations?

A.To get astronauts to keep healthy.

B.To help astronauts do experiments.

C.To provide astronauts a basic living condition.

D.To save the cost of transporting water up to space.

【3】Scientists get rid of bacteria in the wastewater by ________.

A.recycling

B.freezing

C.heating

D.collecting

【4】What does the text mainly talk about?

A.Water recycled from urine tastes good.

B.How to recycle the wastewater on space.

C.New technology is used in the Chinese space station.

D.CNSA uses a high-tech machine to recycle wastewater for astronaut stations.

Answer 1

【答案】

【1】A

【2】D

【3】C

【4】D

【解析】

本文是一篇說明文。短文主要描述了在空間站上水的回收利用問題�？茖W家們用一種高科技機器把人員在空間站上產(chǎn)生的廢水，回收利用，從而減少往空間站運水的費用。

【1】

細節(jié)理解題。根據(jù)短文第二段的 The machine will recycle everything from sweat, the water for washing hands, shower water, water used for brushing teeth, and even urine, to make drinking water.(這臺機器將回收所有從汗水，洗手的水，淋浴的水，用于刷牙的水，甚至尿液，以制造飲用水)可知,從尿液中回收的水被用來飲用。故選A。

【2】

細節(jié)理解題。根據(jù)短文第三段It saves CNSA millions of YMB each year. At present, each CNSA astronaut uses about 4.4 liters of water every day. It costs about ￥150 million a year to transport water up to space.可知，它每年節(jié)省CNS數(shù)百萬人民幣。 目前，每個CNSA宇航員每天使用約4.4升水。每年要花費1.5億元，將水輸送到太空。因此可知用高科技機器來節(jié)約送水去空間站的花費。故選D。

【3】

細節(jié)理解題。根據(jù)最后一段the water will be heated to 130C to get rid of bacteria可知，水將被加熱到130℃以殺死細菌，故選C。

【4】

主旨大意題。通讀全文特別是第二段的首句China National Space Administration(CNSA)says it uses a high-tech machine to recycle wastewater.(中國國家航天局(CNSA)說，它使用一臺高科技機器回收廢水) 可知，這篇短文主要是關于國家航天局使用高科技機器為太空站回收廢水。故選D。
