Question

【題目】

New research suggests that growing trees and other plants near factories could reduce pollution by almost one- third.

More plant life may even cost less and be more effective (有效的) than technology designed to cut pollution, a new study found. Researchers collected data about air pollution and plant life in 48 cities. They studied public records from every city.

The researchers knew that trees and plants are taking in large amounts of harmful air. So they tried to find out whether new plants could reduce air pollution.

The study tried to show how this vegetation (植被) could reduce the pollution, including the production of energy from coal, oil and gas. The researchers found that growing plants, where possible, could cut air pollution by about 27 percent in the areas studied. They also found that in 75 percent of the areas, it would cost less to use plants and trees to reduce air pollution than to add new air cleaning technology.

"The fact is that traditionally, especially as engineers, we don't think about nature," Dr. Bakshi, said. "We just focus on putting technology into everything."

"To solve air pollution problems, people need to start learning from the nature and respecting it," Bakshi said. He added that nature-based methods could result in "win-win" solutions that save money and are better for the environment.

The study couldn't tell which kinds of trees or plants would be best at reducing air pollution. But Bakshi said they might make a difference in air quality, so further study is needed.

The researchers said that more trees and plants could help lower air pollution levels in both cities and rural areas. However, success rates (比率) would be different depending on how much land can be used and its air quality levels.

【1】The researchers found that plants were ________ air cleaning technology.

A.better thanB.worse thanC.as cheap asD.as good as

【2】Most engineers think ________ is more important in reducing air pollution.

A.natureB.costC.locationD.technology

【3】What do "win-win" solutions refer to in Paragraph 6?

A.Building more factories to develop technology.

B.Reducing air pollution with less money.

C.Saving more money by developing technology.

D.Developing technology and reducing pollution.

【4】What can we learn from the passage?

A.1/3 of the pollution can be reduced by technology.

B.The study has found out the most effective plants.

C.Plants improve the air quality in cities and the country.

D.Air quality levels mainly decide the success rates.

Answer 1

【1】A

【2】D

【3】B

【4】C

【解析】

文章主要講了新的研究發(fā)現(xiàn)種植樹木和其他植物可以減少空氣污染。這種方式既省錢有對(duì)環(huán)境有好處，可以得到雙贏的結(jié)果。

【1】

細(xì)節(jié)理解題。由文中第二段第一句提到“More plant life may even cost less and be more effective than technology designed to cut pollution”和減少污染的技術(shù)相比，植物花費(fèi)少并且更加有效率，得出綠植比凈化空氣的技術(shù)更好，故選A。

【2】

細(xì)節(jié)理解題。從文中第五段第一句“... we don’t think about nature, ... we just focus on putting technology into everything.”可知，他們關(guān)心的是技術(shù)，故選D。

【3】

詞義猜測(cè)題。由劃線部分后面“that save money and are better for the environment”可知，這里是對(duì)前面詞的解釋，這種方法既省錢也能對(duì)環(huán)境有益，所以“win-win” solutions指的是“雙贏”即用更少的錢減少污染，故選B。

【4】

細(xì)節(jié)理解題。A選項(xiàng)定位文中第一句話“growing trees and other plants near factories could reduce pollution by almost one-third”種植樹木和植物可以減少 1/3 的污染，并非科技減少，因此A錯(cuò)誤；B選項(xiàng)中定位文中倒數(shù)第二段的第一句“The study couldn’t tell which kinds of trees or plants would be best at reducing air pollution.”得出目前還未發(fā)現(xiàn)可以最有效減少污染的綠植，因此B錯(cuò)誤；D選項(xiàng)定位文中最后一句話“success rates would be different depending on how much land can be used and its air quality level.”得出成功率由土地利用的多少和空氣質(zhì)量共同決定，并非完全由空氣質(zhì)量決定， 因此D錯(cuò)誤；C選項(xiàng)定位文中最后一段第一句 “… could help lower air pollution level in both cities and rural areas”得出綠植在城市和農(nóng)村都可減少空氣污染，提高空氣質(zhì)量，故選C。
