11、rts with increasingly massive security lines.Americans are willing to tolerate time-consuming security protocols 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
12、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 mentioninfuriating.Last year, the Transportation Security Administration(TSA) found in a secret check that
13、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 economy and low oil prices, have resulted in long waits at major airports such
14、 as Chicagos O Hare International. It is not yet clear how much more effective airline security has become but the lines are obvious.Part of the issue is that the government did not anticipate the steep increase in airline travel, so the TSA is now rushing to get new screeners on the line. Part of t
15、he issue is that airports have only so much room for screening lanes. Another factor may be that more people are trying to overpack their carry-on bags to avoid checked-baggage fees, though the airlines strongly disputethis.|There is one step the TSA could take that would not require remodeling airp
16、orts or rushing to hire: Enroll more people in the PreCheck program. PreCheck is supposed to be a win-win for travelers and the TSA. Passengers who pass a background check are eligible to use expedited screening lanes. This allows the TSA to focus on travelers who are higher risk, saving time for ev
17、eryone involved.

Since the beginning, this price tag has been PreChecks fatal flaw. Upcoming r

But Congress should look into doing so directly, by helping to finance PreCheck enrollment or to cut costs in other ways.The TSA cannot continue diverting resources into underused PreCheck lanes while most of the traveling public suffers in un

20、e importance of privacy protection.答案 A答案解释 根据题干关键词 The Crash of EgyptAir Flight 804 定位到第一段第 3 句。该句提到埃及航空公司的 804 航班被击落又一次提醒了为什么要进行安检。该句的前两句提到了美国的大型机场对旅客提出了更多的安检要求,但旅客为了安全愿意忍受耗时的安检程序。所以 A 符合文意。22. Which of the following contributes to long waits at major airports?|A New restrictions on carry-on bags.
21、B The declining efficiency of the TSA.C An increase in the number of travellers.D Frequent unexpected secret checks.答案 C答案解释 根据题干关键词 long wait 定位到第二段第 2 句。这句话中提到加强的安全措施和航空旅游的数量的增加导致了大型机场的 long wait。题干中用 contribute to,原文中用同义短语 result in。选项 C 中的 an increase in the number of travellers 和原文中的 rise inair
