Question

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.”

1.Which of the following is the disadvantage of the sweat machine?

A. The amount of water the machine produces is rather limited.

B. It takes too long for the machine to produce water.

C. It costs a large amount of money to build the machine.

D. The water processed by the machine is not clean enough.

2.UNICEF is mentioned in the text to ________.

A. show how the sweat machine works

B. show the importance of the United Nations

C. explain why the sweat machine was invented

D. tell us who invented the sweat machine

3.What did Mattias Ronge think of the sweat machine?

A. It could only be used in summer.

B. It was not worth popularizing.

C. It did not work at all.

D. The water it produced tasted sweet.

4.The 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

D. the pill which turns dirty water into clean water is produced

Answer

1.A

2.C

3.B

4.B

【解析】文章主要介绍了能够将汗水变成饮用水的机器sweat machine发明的目的、原理和缺点。

1.A

推理判断题。根据第五段one person’s T-shirt typically produces 10ml, about a mouthful.最后一段People haven’t produced as much sweat as we hoped和the demand for sweat is greater than the supply可知人出汗的量太小，对汗水的需求大于供给。这是sweat machine的一大缺点，故选A.

2.C

推理判断题。根据第三段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 access to clean water.可知sweat machine发明的目的是为了宣传世界上有7.8亿人缺乏清洁用水这一事实。故选C.

3.B

推理判断题。根据最后一段Mattias Ronge 列举的People haven’t produced as much sweat as we hoped ——right now the weather in Gothenburg is lousy和the demand for sweat is greater than the supply. And the machine will never be produced in large numbers等缺点可知Mattias Ronge认为sweat machine不值得普及，故选B.

4.B

推理判断题。文章主要介绍了能够将汗水变成饮用水的机器sweat machine已经问世，并介绍了其发明的目的、原理和缺点。故选B.

推理判断题的常见考查形式及解题方法：

推理判断题属于主观题，是层次较高的题目。它包括判断和推理题。这两类题常常相互依存，推理是为了做出正确的判断，正确的判断又依赖于合乎逻辑的推理。此类题要求在理解表面文字的基础上，做出判断和推论，从而得到文章的隐含的意思和深层的意思，也就是通过文章中的文字信息，上下逻辑关系及事物的发展变化等已知的信息，推断出作者没有直接表达的态度和观点。

本文推理判断题的考法：

1)推测文章的观点或结论。小题1考查sweat machine的缺点，根据第五段one person’s T-shirt typically produces 10ml, about a mouthful.最后一段People haven’t produced as much sweat as we hoped和the demand for sweat is greater than the supply可知人出汗的量太小，对汗水的需求大于供给。这是sweat machine的一大缺点。小题3考查Mattias Ronge对sweat machine的观点，根据最后一段Mattias Ronge 列举的People haven’t produced as much sweat as we hoped ——right now the weather in Gothenburg is lousy和the demand for sweat is greater than the supply. And the machine will never be produced in large numbers等缺点可知Mattias Ronge认为sweat machine不值得普及。

2)推测作者写作目的或意图。小题2考查sweat machine发明的目的根据第三段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 access to clean water.可知sweat machine发明的目的是为了宣传世界上有7.8亿人缺乏清洁用水这一事实。小题4考查作者的写作目的，文章主要介绍了能够将汗水变成饮用水的机器sweat machine已经问世，并介绍了其发明的目的、原理和缺点。
