A^anewregulationforallairlines

B、thedefectsofelectronicdevices

C、apossiblecauseofaircraftcrashes

D^effectivesafetymeasuresforairflight

標(biāo)準(zhǔn)答案：C

知識點角落斤：考查主題。主題一般在第一段段首。如果這個題出現(xiàn)在中間的話，一

般對應(yīng)某一段的內(nèi)容和主題，范圍小一點，比較容易。如果是第一題或最后一題，

則對應(yīng)整篇文章。本文的主題是關(guān)于電磁干擾可能影響飛機安全，故選C。

2、Whatissaidabouttheover100aircraftincidentsinthepast15years?

A、Theymayhavebeencausedbythedamagetotheradiosystems.

B、Theymayhavetakenplaceduringtake-offandlanding.

C^Theywereprovedtohavebeencausedbythepassengers'portablecomputers.

D、Theyweresuspectedtohaveresultedfromelectromagneticinterference.

標(biāo)準(zhǔn)答案：D

知識點解析：題干有數(shù)字，很容易在文中第一段找到對應(yīng)的句子。注意could,表

示可能，所以選D：懷疑他們是電磁干擾的結(jié)果。

3、Fewairlineswanttoimposeatotalbanontheirpassengersusingelectronicdevices

D^theyhaveothereffecrivesafetymeasurestofallbackon

標(biāo)準(zhǔn)答案：C

知識點解析：關(guān)鍵句在第二段最后一句，giventhatmanypassengerswanttowork

duringflights.很多乘客要在飛行期間工作，可以推斷一些航空公司拒絕禁令的原

因是：如果他們推行了禁令，也許許多需要在飛機上工作的乘客就不會選擇乘坐飛

機了。故選Co

4、Whyisitdifficulttopredictthepossibleeffectsofelectromagneticfieldsonan

A、Becauseitisextremelydangeroustoconductsuchresearchonanairplane.

B、Becauseitremainsamysterywhatwavelengthsareliabletobeinterferedwith.

C、Becauseresearchscientistshavenotbeenabletoproducethesameeffectsinlabs.

D、Becauseexpertslackadequateequipmenttodosuchresearch.

標(biāo)準(zhǔn)答案：C

知識點露斤：第三段because后面給出了解釋：因為他們不能在實驗室重現(xiàn)這些影

響，所以他們沒辦法知道干擾是不是有危險。所以選C。A文中沒有說過，B和第

二句相反，D沒有提到c

5、Itcanbeinferredfromthepassagethattheauthor.

A^isinfavorofprohibitingpassengers'useofelectronicdevicescompletely

B、hasoverestimatedthedangerofelectromagneticinterference

C、hasn'tformedhisownopiniononthisproblem

D^regardsitasunreasonabletoexerciseatotalbanduringflight

標(biāo)準(zhǔn)答案：C

知識點解析：作者沒有很明確的態(tài)度，只是做客觀的說明，描寫了很多情況，但沒

有表明自己的立場和看法。A贊成禁令；B高估危險；C沒有形成自己的觀點；D

認為禁令無理。

B>directtheoutnumberedRAFplaneseffectively

C>confuseGermanbomberpilots

D、bothAandB

標(biāo)準(zhǔn)答案：D

知識點解析：文章第二段提到在第二次世界大戰(zhàn)中，英國人利用無線電波可以偵查

出德國飛機的位置，而且那些數(shù)量占多數(shù)的皇家空軍常常會對德軍造成一定的困

惑，第三段提到那些皇家空軍是由那些無線電波指控的。故A項和B項都正確，

所以選D。

10>IheBritishusedradiowavesbecausethey.

A、weremoreexactthansoundwaves

B、couldnotbedetected

C>couldpenetratefogandclouds

D、wereeasiertousethansoundwaves

標(biāo)準(zhǔn)答案：C
