6、pilotsCengineers Dconductors答案B解析文章第一句已表明：当今航空公司面对的最大的安全威胁不是持枪的恐怖分子，而是手提电脑。对飞机上的这种事情最了解的应是飞行员。2A.actions BeventsCmatters Dincidents答案D解析此处指飞机上发生的这类事情，incident指较小的事件、插曲、小故事。3A.reason BeffectCsource Dstory答案C解析根据下句话得知“手提电脑，移动电话”等这些电子装置应是“干扰源”，而不是受干扰的结果，受干扰的应当是飞机。4A.and BforCbut Dso答案C解析“没有确认”(unconfir
7、med)与“在增加”(increasingly)中间应是转折关系。5A.advises BpersuadesCensures Dwarns答案A解析因为下文用了recommend(劝告)一词，所以这个组织应该是向航空工业提建议的一个组织，这样才前后一致。6A.some BseveralCall Dno答案C解析因为这种电磁的(electromagnetic)干扰对飞机航空的安全造成最大的威胁，所以应该是所有的飞机都要有这样的禁令。7A.for BwithCby Dduring答案D解析此处指飞机在飞行期间的一些对技术设备要求严格、要求高的时期，一定要严禁使用此类装置。8A.particular
8、ly BspeciallyCunfortunately Dpossibly答案A解析据上面解释，特别是起飞、降落时。9A.looking BcallingCwaiting Dasking答案B解析有些专家要求更高，要求飞行期间全面禁用。call for需要，要求。10A.put BleftCgiven Dsent答案B解析表示目前使用这些设置的规矩都留了下来。11A.carrying BtakingCfixing Dusing答案D解析这种装置可以携带，不能使用，一旦使用产生电磁效应干扰，所以选D项。12A.possibility BdifficultyCnecessity Didea答案B解
9、析推断出电磁效应是如何影响飞机的计算机，这在目前是件难事，如果不难，科学家能解决，就不必有禁令了，所以选difficulty。13A.must BshouldCneed Dmight答案D解析表示“可能”，因为拿不准，语气轻。14A.know BtellCguess Dthink答案A解析这些手提装置已广为人们所用，所以科学家“知道”。15 A.aircraft BtrainsCships Dcars答案A解析该文讲的都是航空，选A(飞机，飞行器)。16A.restudy BretellCreproduce Drenew答案C解析该句主语为they，指的是那些有电磁效应的装置，选C项，意为“再
10、现”；而renew意为“更新，重新开始”。17A.key BwayCstep Dtrick答案B解析因为这些装置的干扰情况在实验室里还未能再现，所以科学家们就没有办法得知这种干扰是否危险。18A.dangerous BstrongChelpful Duseful答案A解析由上题解析可知选A。19A.faces BraisesCruns Dtakes答案B解析飞机容易受干扰攻击的这一事实增加了恐怖分子冒险利用无线电系统破坏航空设备的可能性。20A.repair BguideClead Ddamage答案D解析恐怖分子只会冒险破坏，而不会去修理、引导等。.阅读理解June 26,2000the H

24、w to defeat fatal diseases作动词learn的宾语。如何利用语境选择正确答案？做语境化选择题，要立足语篇环境，树立全局观念，瞻前顾后，连贯思维，从语境角度来选择答案。选项通常具有暗示性和后线索性。平时训练要遵循以下答题技巧：1避免只注重语境，忽略基本的习惯搭配及习惯用法很多考生在此类试题中丢了分，究其原因是考生只注重语境，而忽视了词汇的习惯搭配、语法知识和习惯用法。所以考生在准确掌握语境的同时，更要注意所要填入的名词、形容词、动词与空格前面或后面某个词汇的习惯搭配，掌握常见词汇的习惯用法。2巧妙利用平行结构，准确判断逻辑关系平行结构形式整齐匀称，内容上联系紧密。命题者常从平行结构的句式相同或相似这一角度，利用其意义的关联或对比这一特点来设空。高考完形填空常常会出现这样一些平行结构，掌握与这些结构极为相似的句子可以大大提高解题效率。如本节完形填空中的第4空The_3(source) of this interference remains unconfirmed，_4_ increasingly，experts are pointing the blame at portable electronic devices such as.，“没有确认”(unconfirmed)与“在增加”(increasingly)中间应是转折关系，不是其他关系，故选C项。
