C.apossiblecauseofaircraftcrashes

0.effectivesafetymeasuresforairflight

答案:C［解析］考查主題。主題一般在第一段段首。如果這個(gè)題出現(xiàn)在

中間的話，一般對(duì)應(yīng)某一段的內(nèi)容和主題，范圍小一點(diǎn)，比較容易。

如果是第一題或最后一題，則對(duì)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(jī)安全，故選

B.Theymayhavetakenplaceduringtake-offandlanding.

C.Theywereprovedtohavebeencausedbythepassengers'

portablecomputers.

D.Theyweresuspectedtohaveresultedfromelectromagnetic

interference.

答案:D［解析］題干有數(shù)字，很容易在文中第一段找到對(duì)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。

D.theyhaveothereffectivesafetymeasurestofallbackon

答案:C［解析］關(guān)鍵句在第二段最后一句，giventhatmany

passengerswanttoworkduringflights.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(jī)上工作的乘客就不會(huì)選擇乘坐飛機(jī)了。故選

答案:C［解析］第三段because后面給出了解釋：因?yàn)樗麄儾荒茉趯?shí)

驗(yàn)室重現(xiàn)這些影響，所以他們沒(méi)辦法知道干擾是不是有危險(xiǎn)。所以選

文中沒(méi)有說(shuō)過(guò)，和第二句相反，沒(méi)有提到。

答案:C［解析］作者沒(méi)有很明確的態(tài)度，只是做客觀的說(shuō)明，描寫了很

多情況，但沒(méi)有表明自己的立場(chǎng)和看法。A贊成禁令；B高估危險(xiǎn);

C沒(méi)有形成自己的觀點(diǎn)；D認(rèn)為禁令無(wú)理。
