2-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 American's economic and private lives, not to mention infuriating.

[D] emphasize the importance of privacy protection.
3-Last year, the Transportation Security Administration 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 on airline travel due to the improving economy and low oil prices, have resulted in long waits at some major airports such as Chicago O'Hare International. It is not yet clear how much more effective airline security has become, but the lines are obvious.

[B] The declining efficiency of the TSA.
[C] An increase in the number of travellers.
[D] Frequent unexpected secret checks.
carry-on 手提的
4-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 the issue is that airports have only so much room for screening lanes. Another factor may be that most people are trying to overpack their carry-on bags to avoid checked-baggage fees, though the airlines strongly dispute this.
only so much 有限的
screener 筛选器
checked-baggage 托运行李
5-There is one step the TSA could take that would not require remodeling airports 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 TSA to focus on travelers who are higher risk, saving time for everyone involved. The TSA wants to enroll 25 million people in PreCheck.
are eligible to 有权 ...
23. The word “expedited” (Liner 4, Para. 5) is closest in meaning to____
[A] quieter.
It has not gotten anywhere close to that, and one big reason is sticker shock. Passengers must pay 85 dollars every five years to process their background checks. Since the beginning, this price tag has been PreCheck's fatal flaw. Upcoming reforms might bring this price to a more reasonable level. But Congress should look into doing so directly, by helping to finance PreCheck enrollment or to cut costs in other ways.

[C] the government’s reluctance to back支持 it.
[D] an unreasonable price for enrollment.
implementation 实施；生效；完成;工具
implement 执行;实施
complement 补充
supplement 增补

The TSA cannot continue diverting resources into underused PreCheck lanes while most of traveling public suffers in unnecessary lines. It is long past time to make this the program work.
25. Which of the following would be the best title for the text?
[B] PreCheck – a Belated Solution
[C] Getting Stuck in Security Lines
