Question

Cities need to put efforts to deal with pollution and clear the air.
Chinese cities will need to put efforts to clear up the sky when a new department to improve regional air quality is set up by 2015，according to the latest plan released by the State Council.
Besides the existing pollution control program for CO₂，regional emission caps(區(qū)域排放上限) for other certain chemicals will be established in the three key air polluting areas—the Yangtze River Delta，Pearl River Delta and the Beijing­-Tianjin­- Hebei region. Coal­-consumption caps will also be tried out in some areas，according to the plan.
The plan is aimed at dealing with regional air pollution—such as acid rain and smog—which have become increasingly obvious in China in recent years and caused a severe threat to people’s health，Zhang Lijun，vice­minister of environmental protection，said in an interview on Monday.
The air quality in a city affects the areas nearby because pollutants can travel in the sky，said Chai Fahe，vice-­director of Chinese Research Academy of Environmental Sciences.
“So efforts to reduce air pollution in a single city，targeting a certain pollutant(污染物) will not be enough，” Chai said.
Zhang said the country’s major industrial districts—the Yangtze River Delta，Pearl River Delta and the Beijing­-Tianjin-­Hebei region—have recorded more than 100 misty days annually in recent years.
These three regions，home to at least 200 million people，occupy only 6.3 percent of the country’s area but consume 40 percent of the country’s coal and produce half of its steel，according to official figures.
Studies also show that the visibility(能見(jiàn)度) in eastern regions of China has dropped by 7 to 15 km compared to that in the early 1960s，as a result of air pollution.
Liaoning province，the Shandong Peninsula，Wuhan in Hubei province and its surrounding area，the Changsha­-Zhuzhou­-Xiangtan region in Hunan province，the Chengdu­-Chongqing region，and the western coast of the Taiwan Straits are also listed as areas to carry out such regional air pollution control programs，according to the plan.
The new plan also requires an improved air quality system，which will measure the pollution levels. “The current system，which only measures some major pollutants，cannot reflect the_truepicture.” said Chai.
【小題1】It will not be enough to reduce air pollution in a single city because ________.

A．a(chǎn)ir pollution has been becoming more and more serious in recent years

C．a(chǎn)ir pollutants in a city can travel in the sky and affect nearby areas

D．a(chǎn)ir pollutants stay in fixed places over the cities

【小題2】Suppose the visibility in eastern regions of China was 130 km in the early 1960s，the visibility there nowadays is ________.

A．123 to 115 km	B．137 to 145 km
C．123 to 145 km	D．115 to 137 km

【小題3】The main purpose of the passage is ________.

A．to inform readers of the damage caused by air pollution

B．to introduce the new plan to control air pollution

C．to provide official figures of air pollution levels

D．to point out the regions affected by air pollution

【小題4】What does the underlined phrase “the true picture” in the last paragraph mean?

A．The major pollutants.

B．The key polluted areas.

C．The major polluted cities.

D．The pollution levels.

Answer 1

【小題1】C
【小題2】A
【小題3】B
【小題4】D

解析試題分析：本文中介紹了應(yīng)對(duì)空氣污染的一些計(jì)劃。
【小題1】根據(jù)文章第五段第一句The air quality in a city affects the areas nearby because pollutants can travel in the sky，故選C。
【小題2】根據(jù)Studies also show that the visibility(能見(jiàn)度) in eastern regions of China has dropped by 7 to 15 km compared to that in the early 1960s，as a result of air pollution.計(jì)算得出，故選A。
【小題3】根據(jù)第三段第一行，第四段第一行，以及最后一段第一行中的關(guān)鍵詞“pollution control program”，“The plan”，“The new plan”可知，故選B。
【小題4】根據(jù)The new plan also requires an improved air quality system，which will measure the pollution levels. “The current system，which only measures some major pollutants，cannot reflect the_truepicture.” said Chai.得知the_true picture指代上一句中的the pollution levels，故選D 。
考點(diǎn)：本題是一篇說(shuō)明文。
點(diǎn)評(píng)：先閱讀問(wèn)題，然后帶著問(wèn)題，再讀全文，找出答題所需要的依據(jù)，完成閱讀。本文中生詞很多，雖然文章對(duì)詞意都做了標(biāo)注，但仍然會(huì)使部分學(xué)生產(chǎn)生抵觸情緒，所以做這類閱讀理解時(shí)我們一定要控制自己的情緒，不要因?yàn)樯�詞而煩躁。在詞義與句義理解的基礎(chǔ)上，結(jié)合上下文總結(jié)歸納某一段或幾段的大意，對(duì)于把握文章主旨，分析全文結(jié)構(gòu)都是至關(guān)重要的。此類題型考查了讀者段落或文章某一板塊的理解概括能力。
