1、Americans are willing to tolerate time-consuming security procedures in return for increased safety. The crash of Egypt Air Flight 804, which terrorists may have downed over the Mediterranean Sea, provides another tragic reminder of why. But demanding too much of air travelers or providing too little security in return undermines public support for the process. And it should: Wasted time is a drag on Americans' economic and private lives, not to mention infuriating.（节选自2017年考研英语一Text1）
【题目】
1. The crash of Egypt Air Flight 804 is mentioned to.
[A] stress the urgency to strengthen security worldwide.
[B] explain Americans' tolerance of current security checks.
[C] highlight the necessity of upgrading major US airports.
[D] emphasis the importance of privacy protection.
【解析】
根据题干信息“The crash of Egypt Air Flight 804”定位在第二段，其中*一句Americans are willing to tolerate time-consuming security procedures in return for increased safety，即“美国人愿意忍受耗时的安检程序以确保安全”，紧接着下一句The crash of Egypt Air Flight 804，which terrorists may have downed over the Mediterranean Sea，provides another tragic reminders of why.即“埃及航空804的坠毁（由于恐怖分子，可能坠入地中海）给大家一个悲剧提醒，为什么这样做”。因此，埃及航空804坠毁是为了给人们提示为什么美国人愿意忍受耗时的安检程序。故[B]explain Americans'tolerance of current security checks为正确答案。
2、Last year, the Transportation Security Administration (TSA) found in a secret check that undercover investigators were able to sneak weapons-both fake and real-past airport security nearly every time they tried. Enhanced security measures since then, combined with a rise in airline travel due to the improving Chicago's O' Hare International. It is not yet clear how much more effective airline security has become—but the lines are obvious.（节选自2017年考研英语一Text1）
【题目】
2.Which of the following contributions to long waits at major airport?
[A] New restrictions on carry-on bags.
[B]The declining efficiency of the TSA.
[C] An increase in the number of travelers.
[D]Frequent unexpected secret checks.
【解析】根据题干关键信息“long waits at major airports”直接定位到第三段第二句。该句指出，…enhanced security measures，combined with a rise in airline travel，have resulted in long waits at major airports（加强的安全措施，以及航空旅行人数的增多，导致了主要机场的长时间排队等候）。可见，导致主要机场的长时间排队等候的因素有两个：enhanced security measures（加强的安全措施）和a rise in airline travel（航空旅行人数的增多）。[C]选项中an increase和文中a rise为同义替换，travelers和airline travel为同义替换。故[C]选项是对原文的同义替换，为正确答案。
