A machine that takes sweat-laden (浸满汗水的) clothes and turns the sweat into drinking water is in use in Sweden. The machine makes the clothes turn round quickly, heats them to remove the sweat, and then passes the steam through a kind of special material to make purified water.

Since it has been brought into use, its creators say more than 1000 people have drunk others’ “sweat” in Gothenburg. They add the liquid is cleaner than local tap water.

The device was built for the United Nations’ child-focused charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack access to clean water.

The machine was designed and built by the engineer Andreas Hammar, known locally for his appearances on TV tech show “Mekatronik”. He said the key part of the sweat machine was a new water purification part developed by a company named HVR.

“It uses a technique called membrane distillation (膜蒸馏),” he told the BBC. “We use a special kind of material that only lets steam through but keeps bacteria, salts, clothing fibers and other things out. They have something similar to the International Space Station, but our machine is cheaper to build. The amount of water it produces depends on how sweaty the person is, but one person’s T-shirt typically produces 10ml, about a mouthful.”

The device has been put on show at the Gothia Cup-the world’s largest international youth football tournament. Mattias Ronge, chief executive of Stockholm-based advertising agency Deportivo, said the machine had helped raise awareness for UNICEF, but in reality had its limitations.

“People haven’t produced as much sweat as we hoped – right now the weather in Gothenburg is lousy,” Mattias Ronge said. “So we’ve equipped the machine with exercise bikes and volunteers are cycling like crazy. Even so, the demand for sweat is greater than the supply. And the machine will never be produced in large numbers, since there are better solutions out there such as water purifying pills.”

h of the following is the disadvantage of the sweat machine?

amount of water the machine produces is rather limited.

takes too long for the machine to produce water.

costs a large amount of money to build the machine.

water processed by the machine is not clean enough.

EF is mentioned in the text to ________.

how the sweat machine works               the importance of the United Nations

ain why the sweat machine was invented   us who invented the sweat machine

did Mattias Ronge think of the sweat machine?

could only be used in summer.                   was not worth popularizing.

did not work at all.                                    water it produced tasted sweet.

text is written mainly to tell us that ___________.

A.780 million people in the world lack access to clean water

B.a machine which turns sweat into drinking water is invented

C.a better solution to purifying dirty water is discovered

pill which turns dirty water into clean water is produced

【回答】

1.A; 2.C; 3.B; 4.B 解析：1.推理判断题.根据最后一段"So we've equipped the machine with exercise bikes and volunteers are cycling like  so,the demand for sweat is greater than the supply.所以我们装备健身自行车,志愿者疯狂的骑自行车.即便如此,汗水的需求大于供给可知.因为人们并没有分泌出很多的汗水,所以这种机器净化出的水的数量也很少.故选A. 2.推理判断题.根据文章第三段The device was built for the United Nations'child-focused charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack accessto clean water.可知这台装置是为了联合国的慈善机构UNICEF而设计的,目的是为了提高人们对于清洁水源的保护.所以提到UNICEF就是为了解释设计这一机器的原因.故C正确. 3.推理判断题.根据最后一句And the machine will never be produced in large numbers,since there are better solutions out there such as water purifying pills可知Mattias Ronge认为这种机器不可能被大量生产,因为有比它更好的处理净化水的方法,这种机器不值得推广.故B项正确. 4.主旨大意题.本文介绍了一种能够把人的汗水变成清洁的饮用水的机器的工作原理以及人们对这一机器的看法;故选B.
