太阳能发电或能解决雾霾问题
太阳能发电或能解决雾霾问题

China is well-known for its heavy smog. “It’s very bad,” Denise Mauzerall, an atmospheric scientist at Princeton, said. “The air pollution in eastern China can be so bad that you can’t clearly see across the street. It can feel like you’re walking through a heavy fog that’s burning your lungs.”
But smog has other damaging effects too. Mauzerall and her team have found that in winter months the smog in China’s northeastern provinces is so severe that it blocks more than 20 percent of sunlight from reaching the region’s solar panels.
The findings, based on satellite data and photovoltaic performance models, are in the Proceedings of the National Academy of Sciences.
One solution to the problem might be installing even more solar panels. “This is a virtuous cycle—whereas if you use more solar electricity, you can reduce your use of coal. And that will reduce the air pollution levels, and that will then allow you to produce more solar electricity.”
China hopes to harvest 10 percent of its electricity from solar by 2030. They’ll need 400 gigawatts, or about 10 times what we have installed in the US today. It’s an optimistic forecast for solar electricity and hopefully, for China’s air quality, too.

1.What does the underlined word “severe” mean in Chinese?

A 稀薄的.

B 少量的.

C 严重的.

D 明亮的.

解析：选C。词义猜测题。根据上下文可知是说雾霾严重导致有的阳光穿透不下来，故选C。

2.What is the direct benefit of installing more solar panels?

A It can reduce the air pollution.

B It can reduce the frequency of smog.

C It can help produce more solar electricity.

D It can reduce the use of coal.

解析：选D。细节理解题。根据第四段第二句whereas if you use more solar electricity, you can reduce your use of coal.可知多安装太阳能发电板可以减少煤炭的使用量，这是直接的好处，故选D。

3.The current solar panels can produce _______.

A 40 gigawatts

B 400 gigawatts

C 360 gigawatts

D 4000 gigawatts

解析：选A。细节理解题。根据最后一段第二句They’ll need 400 gigawatts, or about 10 times what we have installed in the US today.可知期待2030年能够用太阳能发电400千兆瓦，是现在的10倍，即现在的装配量是40千兆瓦，故选A。

4.In which column of a newspaper can you find this passage?

A Science.

B Education.

C Environment.

D Economy.

解析：选C。推理判断题。根据本文主要内容“中国雾霾严重，如果多装太阳能或能解决这个问题，并形成一个良性循环”，属于环境板块，故选C。
