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

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

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

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. tell us who invented the sweat machine

C. show the importance of the United Nations

D. explain why the sweat machine was invented

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

A. It did not work at all.

B. It was not worth popularizing.

C. It could only be used in summer.

D. The water it produced tasted sweet.

4.The text is written mainly to tell us that ______________.

A. a better solution to purifying dirty water is discovered

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

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

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

【解析】

试题分析：本文属于科普说明文，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。

1.C 推理判断题。根据最后一段前三句“People haven’t produced as much sweat as we hoped – right now the weather in Gothenburg is lousy,”“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.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C项正确。

2.D 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 access to 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D正确。

3.B 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。

【名师点睛】

本文5.

1．开门见山式

主题句出现在文首。开门见山，提出主题，随之用细节来解释、论证或发展主题思想。这种写作手法叫做演绎法，在英语文章中尤为常见，这种文章的主题句最容易找到，故主题思想显而易见。

2．藏头露尾式

主题句出现在文尾。即文章先阐述了细节，然后归纳要点，得出结论，概括主题，叫做归纳写作法，主题句往往位于末段。这一类文章的主题句也很明显，不难找到。

3．首尾呼应式

在有些文章中，为了突出主题，作者在文章开头提出主题，接着进行阐述或论证，在结尾时再次点出主题，这种首尾呼应的写作方式也很常见。值得注意的是，前后两个主题句不是简单的重复，再次出现的主题句往往是前面主题句的进一步引申或发展。

4．抛砖引玉式

即文章的开头只是提出一个问题或者貌似正确的观点，而真正的主题则是通过对问题的解析和引申，或是通过责问和驳论的方式导出主题。

5．藏龙卧虎式

即主题句隐含在全文当中，没有明确的主题句。阅读这样的文章，要求考生根据文章的细节来分析、概括推导出文章的主题。具体方法是：首先弄清楚各个段落讲了哪几个方面的内容，这些内容在逻辑上有什么联系，寻找共同点,然后加以归纳形成主题。
