科普知识（阅读理解）由 (xx安徽“江南十校”高三联考) 改编

US scientists have fixed experimental sensors (传感器) in some cities to map wind patterns and provide possible lifesaving information in a chemical or biological attack.

Two test models,in the form of nine-meter high aluminum (铝) towers,are now undergoing testing in New York City,one in Greenwich Village and the other near Times Square.

Half a dozen similar sensors have been fixed in and around Washington. Simulations (模仿) of terrorist attacks carried out since the Sep.11,2001 attacks have stressed the importance of finding out as soon as possible those areas that would be most affected by giving out poisonous gas or radioactive material into the air.

Now,the only reliable sources of information on wind speeds and direction are major airports,which are generally located too far away from city centers to be of much use.

The experimental sensors measure wind strength and direction 10 times per second.The information is downloaded through the Internet to puters that can turn out a detailed wind map,updated every 15 minutes.

Addressing a recent House of Representatives mittee meeting,the director of the National Oceanic and Atmospheric Administration (NOAA’s) “Air Resources” laboratory,Bruce Hicks,stressed the importance of developing the wind mapping program.

“The wind sensors now being tested were produced by scientists recognizing there’s a real problem and we’d better start handling it fast or else we’ll get into trouble.”Hicks said.

Funds(资金) during the testing period had been provided by the new Department for Homeland Security which will decide whether to fix sensor networks in major US cities,if the experiment should have positive results.

1.The purpose of developing the wind mapping program is to .

A.get lifesaving information during terrorist attacks B.get useful information about weather changes C.map the speed and direction of the wind D.prevent possible terrorist attacks

2.According to the text,the information from major airports is . A.slowly downloaded B.not quite reliable C.quickly updated D.not very useful

3.From the text,we can learn that the wind mapping program . A.has been put into practical use B.is being experimented

C.is just an idea under discussion D.has finally failed for lack of money 4.What is the text mainly about?( )

A.Scientists’ mapping wind to sense terrorist attacks. B.Whether wind mapping program is useful or not. C.How the wind mapping program works. D.The importance of wind mapping program.

语篇解读:美国科学家在很多主要城市安装了测量风向的传感器,目的是更加精确地为防范生化武器的袭击提供信息。

答案及剖析:1.A 推理判断题。由文章第一段的...to map wind patterns and provide possible lifesaving information in...attack可知选A项。

2.D 细节理解题。由第四段的描述可知,来自主要机场的信息离市中心太远,以至于它们提供的信息用处不大,故选D项。

3.B 细节理解题。由第二段和最后两段可知,the wind mapping program 正在测试当中,故选B项。

4.A 主旨大意题。文章的第一段为本文的主题段,由此可知A项正确。 【疑难词汇解读】 1.undergo v.经历,经受 She is undergoing surgery. 她正在接受手术。

2.poisonous adj.有毒的

New furniture often gives out something poisonous. 新家具常释放有毒的东西。 【长难句子分析】

自2001年9月11日的恐怖袭击以来,针对恐怖袭击进行的模仿已经强调了通过释放有毒气体或放射性物质的方法尽快弄清那些可能受到影响的地方的重要性。

阅读下列短文，从每题所给的四个选项（A、B、C和D)中，选出最佳选项。 【xx高考英语福建省莆田市教学质量检查试卷】
