A^anewregulationforallairlines

B、thedefectsofelectronicdevices

C、apossiblecauseofaircraftcrashes

D^effectivesafetymeasuresforairflight

标准答案：C

知识点角落斤：考查主题。主题一般在第一段段首。如果这个题出现在中间的话，一

般对应某一段的内容和主题，范围小一点，比较容易。如果是第一题或最后一题，

则对应整篇文章。本文的主题是关于电磁干扰可能影响飞机安全，故选C。

2、Whatissaidabouttheover100aircraftincidentsinthepast15years?

A、Theymayhavebeencausedbythedamagetotheradiosystems.

B、Theymayhavetakenplaceduringtake-offandlanding.

C^Theywereprovedtohavebeencausedbythepassengers'portablecomputers.

D、Theyweresuspectedtohaveresultedfromelectromagneticinterference.

标准答案：D

知识点解析：题干有数字，很容易在文中第一段找到对应的句子。注意could,表

示可能，所以选D：怀疑他们是电磁干扰的结果。

标准答案：C

知识点解析：关键句在第二段最后一句，giventhatmanypassengerswanttowork

duringflights.很多乘客要在飞行期间工作，可以推断一些航空公司拒绝禁令的原

因是：如果他们推行了禁令，也许许多需要在飞机上工作的乘客就不会选择乘坐飞

机了。故选Co

4、Whyisitdifficulttopredictthepossibleeffectsofelectromagneticfieldsonan

A、Becauseitisextremelydangeroustoconductsuchresearchonanairplane.

B、Becauseitremainsamysterywhatwavelengthsareliabletobeinterferedwith.

C、Becauseresearchscientistshavenotbeenabletoproducethesameeffectsinlabs.

D、Becauseexpertslackadequateequipmenttodosuchresearch.

标准答案：C

知识点露斤：第三段because后面给出了解释：因为他们不能在实验室重现这些影

响，所以他们没办法知道干扰是不是有危险。所以选C。A文中没有说过，B和第

二句相反，D没有提到c

5、Itcanbeinferredfromthepassagethattheauthor.

A^isinfavorofprohibitingpassengers'useofelectronicdevicescompletely

B、hasoverestimatedthedangerofelectromagneticinterference

C、hasn'tformedhisownopiniononthisproblem

D^regardsitasunreasonabletoexerciseatotalbanduringflight

标准答案：C

知识点解析：作者没有很明确的态度，只是做客观的说明，描写了很多情况，但没

有表明自己的立场和看法。A赞成禁令；B高估危险；C没有形成自己的观点；D

认为禁令无理。

出德国飞机的位置，而且那些数量占多数的皇家空军常常会对德军造成一定的困

惑，第三段提到那些皇家空军是由那些无线电波指控的。故A项和B项都正确，

所以选D。

10>IheBritishusedradiowavesbecausethey.

A、weremoreexactthansoundwaves

B、couldnotbedetected

C>couldpenetratefogandclouds

D、wereeasiertousethansoundwaves
