Question

【题目】

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

【答案】

【1】A

【2】D

【3】B

【4】C

【解析】

文章主要讲了新的研究发现种植树木和其他植物可以减少空气污染。这种方式既省钱有对环境有好处，可以得到双赢的结果。

【1】

细节理解题。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”和减少污染的技术相比，植物花费少并且更加有效率，得出绿植比净化空气的技术更好，故选A。

【2】

细节理解题。从文中第五段第一句“... we don’t think about nature, ... we just focus on putting technology into everything.”可知，他们关心的是技术，故选D。

【3】

词义猜测题。由划线部分后面“that save money and are better for the environment”可知，这里是对前面词的解释，这种方法既省钱也能对环境有益，所以“win-win” solutions指的是“双赢”即用更少的钱减少污染，故选B。

【4】

细节理解题。A选项定位文中第一句话“growing trees and other plants near factories could reduce pollution by almost one-third”种植树木和植物可以减少 1/3 的污染，并非科技减少，因此A错误；B选项中定位文中倒数第二段的第一句“The study couldn’t tell which kinds of trees or plants would be best at reducing air pollution.”得出目前还未发现可以最有效减少污染的绿植，因此B错误；D选项定位文中最后一句话“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气质量共同决定，并非完全由空气质量决定， 因此D错误；C选项定位文中最后一段第一句 “… could help lower air pollution level in both cities and rural areas”得出绿植在城市和农村都可减少空气污染，提高空气质量，故选C。
