4.A Dutch artist and designer has come up with a device which he hopes will get rid of pollutants from Beijing's smog skies,creating clean air for the city's mask-wearing people.
An electromagnetic (電磁)field will pull particles(微粒) in the smog to the ground where they can be easily cleaned."
It's like when you have a balloon which has static(靜電) and your hair goes toward it.Same with the smog,"says artist Daan Roosegaarde.
His studio has reached an agreement with the Beijing government to test the technology in one of tile capital's parks.
With its skies regularly covered by dirty gray smog,Beijing this week announced a series of emergency measures to handle the problem.
Roosegaarde says an indoor model device has already proven it works and is confident that the results-with the help of a team of scientists and engineers-can be replicated outside.
"Beijing is quite a good place because the smog in Beijing is quite low.It lies in a valley so there's not so much wind.It's a good environment to explore this kind of thing."
"We'll be able to purify the air and the challenge is to get the top of the smog so you can see the sun again."
Roosegaarde acknowledges that projects like this are a way of drawing attention to the problem,rather than a practical solution to Beijing's awful air pollution.
"This is not the real answer for smog.The real answer has to do with clean cars,different industry and different lifestyles."
However,he hopes the project will make a"fundamental statement"by allowing the city's people to realize the difference between breathing clean and smog-filled air.

分析 本文為科技內(nèi)說明文;短文主要介紹了荷蘭人Roosegaarde設(shè)置了一種凈化空氣裝置,這種裝置通過電磁場(chǎng)把臟的顆粒吸到地面.然后他們很容易被弄干凈.已經(jīng)證實(shí)這種裝置在室內(nèi)試驗(yàn)有效,并且可以預(yù)見在北京戶外也很適用,因?yàn)檫@種裝置很適合北京;但是Roosegaarde認(rèn)為這個(gè)工程只能是引起對(duì)空氣污染的關(guān)注,而非解決北京空氣污染的實(shí)用的解決方法.
解答 25.答案是B.細(xì)節(jié)理解題;根據(jù)短文第二段"An electromagnetic field(電磁場(chǎng)) will pull particles(微粒) in the smog to the ground where they can be easily cleaned."描述可知這個(gè)設(shè)備的是通過電磁場(chǎng)把臟的顆粒吸到地面.然后他們很容易被弄干凈.故選B
26.答案是C.細(xì)節(jié)理解題;根據(jù)第六段"Roosegaarde says an indoor model device has already proven it works"可知Roosegaarde這一裝置在室內(nèi)已經(jīng)證明是有效的;由第七段中"Beijing is quite a good place"推斷這種裝置適合北京,故可預(yù)見這種裝置在北京使用的結(jié)果,所以選C.
27.答案是C.推斷解題;上文分析了對(duì)這種裝置的測(cè)試,緊接著說明"Beijing is quite a good place",所以推測(cè)Roosegaarde認(rèn)為這種裝置很適合北京,故選C
28.答案是A.細(xì)節(jié)理解題.根據(jù)倒數(shù)第三段Roosegaarde acknowledges that projects like this are a way of drawing attention to the problem,rather than a practical solution to Beijing's awful air pollution.可知Roosegaarde認(rèn)為這個(gè)工程只能是引起對(duì)空氣污染的關(guān)注,而非解決北京空氣污染的實(shí)用的解決方法.故選A.
點(diǎn)評(píng) 閱讀要在整體理解文章的基礎(chǔ)上,在做細(xì)節(jié)題時(shí)根據(jù)題干定位細(xì)節(jié),在語境中正確理解原句,然后對(duì)照選項(xiàng)做出合理的判斷;必要的時(shí)候要進(jìn)行推理,透過句子表面看作者的真正意圖.如果是主旨大意的判斷要把握文章整體,避免以偏概全.
