21.The crash of EgyptAir Flight 804 is mentioned to
[A] explain American’s tolerance of current security checks.
[B] stress the urgency to strengthen security worldwide.
[C] highlight the necessity of upgrading major U.S. airports.
[D] emphasize the importance of privacy protection.
21【A】这是一道例证，按照常规套路文中的例子，所要证明的主题应该在例子之前，所以定位例子的前一句，Americans are willing to tolerate time-consuming security protocols in return for increased safety. 关键信息是tolerate time-consuming security美国人愿意忍耐耗时的安检，对应A选项的内容，同义替换。
22. Which of the following contributes to long waits at major airports?
[A] New restrictions on carry-on bags.
[B] The declining efficiency of the TSA.
[C] An increase in the number of travellers.
[D] Frequent unexpected secret checks.
【C】题干问哪个能够解释为什么美国机场排队很长。定位到第三段第二句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. 原因出现在result in之前。一是因为安检措施，二是因为我们现在经济比较好，机票比较便宜，所以大家都愿意坐飞机。选项中与原文原因相关的只有C，游客数量的增多。
23. The word “expedited” (Liner 4, Para. 5) is closet in meaning to
[A] quieter.
[B] cheaper.
[C] wider.
[D] faster.
23.【D】这是猜词题，定位到改词出现的句子，第五段第三句话：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 everyone involved. 根据指代句的内容，使用use expedited screening lanes这种方法，可以达到这样一种后果saving time for everyone involved.节省大家的时间，所以这道题答案应该选择更快。
24. One problem with the PreCheck program is
[A] a dramatic reduction of its scale.
[B] its wrongly-directed implementation.
[C] the government’s reluctance to back it.
[D] an unreasonable price for enrollment.
【D】该题也是细节定位，通过大写名词找到Since the beginning, this price tag has been PreCheck's fatal flaw.其中提到的问题就是this price tag ，所以答案核心词应该是价格问题，所以答案是D价格不合理。
25. Which of the following would be the best for the text?
[A] Less Screening for More Safety
[B] PreCheck–a Belated Solution
[C] Getting Stuck in Security Lines
[D] Underused PreCheck Lanes
25【C】最后一道是标题。这篇文章都在说安检太长，所以我们应该要提前去安检。这道题一定要选择提前安检的选项，所以应该选B。
