Question

While students in Yinchuan are quite used to clear skies, Beijing teenagers are not so lucky. As another warm winter approaches, the city can expect the normal clouds of smoke caused by air pollution.

But things may start to improve soon. The government is co-operating with a US-based environmental protection agency to update existing buses and trucks with clean fuel technology. The new technology could reduce air pollutants in existing diesel engines(柴油机)by 40 percent. The programme will begin by testing buses in Beijing to see if the technology can be applied to them.

“We encourage the development of public transports. But at the same time we need to reduce pollution from them, ”said an official.

Efforts are being made to improve the capital’s environment with tighter controls on emissions(排放). Some heavily polluting factories and construction sites, such as those owned by the steel giant Shougang Group, have been asked to cut production in November and December or be closed.

Beijing was the third polluted city in the world at the end of last century, according to the UN. But thanks to recent measures, the capital has made some progress. Last year 224 clear days were rated as having good air quality. In 1998 the air quality index(指数)gave just 100 days as good.

“I am glad to see an improvement, ”said a senior 1 boy living in the northwest of Beijing. “Compared to other places, the air quality of Beijing is still worrying though. I hate pollution. Once I was riding my bike in the morning when I almost had a traffic accident because I couldn’t see a car only metres away from me in fog. ”

In early October, the skies were covered by such a thick fog that a display show by the visiting French Air Force was called off.

Rapid development, industry, traffic fumes and sandstorms from the desert all contribute to the city’s bad air.

【解析】

解题分析：文章讲述的是北京的空气污染现状和政府为此而采取的措施。

1.】主旨大意题。通读全文我们不难发现作者是在谈论“北京的空气污染”。A、B两项表示的是政府在治理过程中的措施和进展。D项明显不符文意。故选C。

2.】细节理解题。根据第二段第二句话可知A项正确; 根据第四段第二句话可知B、C两项正确; 根据倒数第二段可知航空飞行表演是因为浓雾被取消, 不是治理空气污染的措施而是空气污染造成的结果, 故选D。

3.】推理判断题。根据短文中一位高一男生所说的：尽管北京在治理空气污染方面取得了一些进展, 但仍然令人担忧, (the air quality of Beijing is still worrying though)，由此可推断：到2008年北京奥运会时北京要达到生态城市的目标，治理工作任重道远， 故选A。

4.】细节理解题。根据第五段第二句话可知A项错误But thanks to recent measures, the capital has made some progress.多亏最近采取的治理空气污染的措施，首都的空气质量比以前有所改善，去年空气质量指数达到良的为224天，而1998年只有100天。 根据最后一段可知B项正确; 根据第一段第二句话可知C项正确; 根据第二段可知D项正确。只有A项与原文内容相悖, 故选A。
