Question

【题目】 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 (复杂的) 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?

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】

本文是一篇说明文。短文主要描述了在空间站上水的回收利用问题。科学家们用一种高科技机器把人员在空间站上产生的废水，回收利用，从而减少往空间站运水的费用。

【1】

细节理解题。根据短文第二段的 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.(这台机器将回收所有从汗水，洗手的水，淋浴的水，用于刷牙的水，甚至尿液，以制造饮用水)可知,从尿液中回收的水被用来饮用。故选A。

【2】

细节理解题。根据短文第三段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，它每年节省CNS数百万人民币。 目前，每个CNSA宇航员每天使用约4.4升水。每年要花费1.5亿元，将水输送到太空。因此可知用高科技机器来节约送水去空间站的花费。故选D。

【3】

细节理解题。根据最后一段the water will be heated to 130C to get rid of bacteria可知，水将被加热到130℃以杀死细菌，故选C。

【4】

主旨大意题。通读全文特别是第二段的首句China National Space Administration(CNSA)says it uses a high-tech machine to recycle wastewater.(中国国家航天局(CNSA)说，它使用一台高科技机器回收废水) 可知，这篇短文主要是关于国家航天局使用高科技机器为太空站回收废水。故选D。
