問題詳情：
A machine that takes sweat-laden (浸滿汗水的) 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 (膜蒸餾),” 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.推理判斷題.根據最後一段"So we've equipped the machine with exercise bikes and volunteers are cycling like so,the demand for sweat is greater than the supply.所以我們裝備健身自行車,志願者瘋狂的騎自行車.即便如此,汗水的需求大於供給可知.因為人們並沒有分泌出很多的汗水,所以這種機器淨化出的水的數量也很少.故選A. 2.推理判斷題.根據文章第三段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.可知這台裝置是為了聯合國的慈善機構UNICEF而設計的,目的是為了提高人們對於清潔水源的保護.所以提到UNICEF就是為了解釋設計這一機器的原因.故C正確. 3.推理判斷題.根據最後一句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認為這種機器不可能被大量生產,因為有比它更好的處理淨化水的方法,這種機器不值得推廣.故B項正確. 4.主旨大意題.本文介紹了一種能夠把人的汗水變成清潔的飲用水的機器的工作原理以及人們對這一機器的看法;故選B.
