Question

【题目】

What is the best way to help control air pollution in our towns and cities? Choose public transportation instead of private cars, or reduce the total amount of cars on the street. These can be useful. But here is a more creative way—write a poem.

"I write in praise of air. I was six or five, when a magician opened my fist(拳头), and I held in my hand the whole of the sky."

Professor Tony Ryan (the science expert) and Professor Simon Armitage(the words expert), from the University of Sheffield, UK, came up with the idea.

But in fact, the poem is not the key part. It is the poster that the poem was written on that plays the biggest part. The poster is 10 meters by 20 meters. It is coated with nanoparticles(纳米粒) of titanium dioxide (二氧化钛). It can absorb the waste from around 20 cars each day if you put it by a busy road. The poster is now displayed on one of the University of Sheffield's buildings.

It doesn't get rid of all the pollutants from traffic, but it will eat up things called nitrogen oxides (氧化氮). These play a part in breathing problems, including asthma(哮喘).

The technology is cheap. "It would add less than 100 to the cost of a poster and would turn advertisements into catalysts(催化剂) in more ways than one," Ryan told the BBC.

He's also working on another idea, which is to add the nanoparticles to washing powder, so that your clothes soak up these poisons while you walk along. And you wouldn't be able to see or feel anything different.

【1】Why can the poem help control air pollution?

A.Because it can warn people of the dangers of pollution.

B.Because the poster that the poem was written on is special.

C.Because it has pictures that explain air pollution.

D.Because Professor Tony Ryan and Professor Simon Armitage are famous.

【2】Which of the following is NOT true of the poster?

A.It is 10 meters by 20 meters.

B.It is coated with nanoparticles.

C.It can absorb the waste from cars.

D.It's widely used in the UK.

【3】From the last two paragraphs, we learn that .

A.the technology costs too much

B.it would make advertisements cheaper

C.washing powder may one day soak up poisons

D.you would feel different wearing the clothes

Answer 1

【1】B

【2】D

【3】C

【解析】

在我们的城镇控制空气污染最好的方法是什么？文章介绍了一种非常有创意的方法——写一首诗。英国谢菲尔德大学的科学专家Tony Ryan和词汇专家Simon Armitage提出了这个想法。但事实上，这首诗并不是重点。这首诗的海报起了最大的作用。海报是10米乘20米的，上面涂有纳米颗粒的二氧化钛。它每天可以吸收大约20辆汽车的废物。他还在研究另一个想法，那就是在洗衣粉中加入纳米粒子，这样你的衣服就能在你走路的时候吸收这些毒素。

【1】细节理解题。题干：为什么这首诗能帮助控制空气污染？根据But in fact, the poem is not the key part. It is the poster that the poem was written on that plays the biggest part. 可知，这首诗并不是重点，能帮助控制空气污染的是这首诗所写在的海报。它是由一种特殊材质做成的，能吸附废物。故选B。

【2】细节理解题。题干：关于海报的描述，下列哪一项是不正确的？选项A. It is 10 meters by 20 meters.根据第四段的The poster is 10 meters by 20 meters.可知，海报是10米乘20米。故选项A正确。选项B. It is coated with nanoparticles.根据第四段的It is coated with nanoparticles(纳米粒) of titanium dioxide (二氧化钛). 可知，它被纳米粒子包裹着。故选项B正确。选项C. It can absorb the waste from cars.根据第四段的It can absorb the waste from around 20 cars each day if you put it by a busy road.可知，它可以吸收汽车的废物。故选项C正确。选项D. It's widely used in the UK.（在英国被广泛使用），在文中并没有提到。根据The poster is now displayed on one of the University of Sheffield's buildings.可知，这幅海报现在陈列在谢菲尔德大学的一栋大楼里。这项技术没有大面积的得意推广，D的说法不正确，故选D。

【3】细节理解题。题干：从最后两段中，我们了解到什么？选项A. the technology costs too much根据倒数第二段的The technology is cheap. 可知，这项技术很便宜，并不是太贵，故选项A不对。选项B. it would make advertisements cheaper根据倒数第二段的It would add less than 100 to the cost of a poster 可知，海报的成本会增加不到100。是贵了一点点，而不是使广告更便宜，故选项B不对。选项C. washing powder may one day soak up poisons根据最后一段He's also working on another idea, which is to add the nanoparticles to washing powder, so that your clothes soak up these poisons while you walk along. 可知，他的另一个想法，那就是在洗衣粉中加入纳米粒子，这样你的衣服就能在你走路的时候吸收这些毒素。也就是说有一天，洗衣粉可能会吸收有毒物质。故选项C是正确的。选项D. you would feel different wearing the clothes根据最后一句话And you wouldn't be able to see or feel anything different.可知，你看不到也感觉不到任何不同。故选项D是不对。故选C。
