　　Text 1

　　First two hours, now three hours — this is how far in advance authorities are recommending people show up to catch a domestic flight, at least at some major U.S. airports 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 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.

　　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 economy and low oil prices, have resulted in long waits at major airports such as Chicago's 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 the 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 dispute this.

　　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 the TSA to focus on travelers who are higher risk, saving time for everyone involved. TSA wants to enroll 25 million people in PreCheck.

　　It has not gotten anywhere close to that, and one big reason is sticker shock: Passengers must pay $85 every five years to process their background checks. Since the beginning, this price tag has been PreCheck's fatal flaw. Upcoming reforms might bring the 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.

　　The TSA cannot continue diverting resources into underused PreCheck lanes while most of the traveling public suffers in unnecessary lines. It is long past time to make the program work.

　　答案：21-25 ACDDC

　　21. 答案【A】explain American’s tolerance of current security checks.

　　解析：本題目為例證題，考察論點(diǎn)與論據(jù)。根據(jù)題干關(guān)鍵詞the crash of Egypt Air Flight 804定位到第二段第二句。例證題中的例子為論據(jù)，所要找的答案為論點(diǎn)，而論點(diǎn)在論據(jù)之前，因此該題目的答案是第二段的第一句話。二段首句說的是美國(guó)人愿意忍受長(zhǎng)時(shí)間的安全檢查。正確答案A的American’s tolerance是原文Americans are willing to tolerate的原詞復(fù)現(xiàn)，current security checks是原文的time-consuming security 的同義轉(zhuǎn)化。干擾項(xiàng)B的urgency to strengthen security worldwide，原文未提及worldwide，屬于擴(kuò)大范圍;選項(xiàng)C的major U.S. major airports屬于具體信息的干擾;選項(xiàng)D的privacy 隱私并未提及，是常識(shí)性干擾。

　　22. 答案【C】An increase in the number of travelers.

　　解析：本題目為原因細(xì)節(jié)題。根據(jù)題干中的long waits at major airports定位到原文第三段的第二句，原文的resulted in 與題干中的contributed to是同義轉(zhuǎn)化，所以定位內(nèi)容就是提升的安全措施以及航空旅游的增加。正確答案C的an increase in the number of travelers 是原文a rise in airline travel的同義替換。干擾項(xiàng)A的carry-on bags是在第四段的最后一句出現(xiàn)的，非定位句內(nèi)容;選項(xiàng)B的TSA efficiency也出現(xiàn)在第四段;選項(xiàng)D的unexpected secret checks未提及。

　　23. 答案【D】faster.

　　解析：本題目為詞義句意題，考察上下文邏輯關(guān)系。根據(jù)題干，定位到第5段第3句，“Passengers who pass a background check are eligible to use expedited screening lanes”，結(jié)合下一句中的這樣會(huì)saving time for everyone involved，即可以節(jié)省時(shí)間的安檢，與選項(xiàng)對(duì)應(yīng)就是答案D faster更快。干擾項(xiàng)A更安靜，選項(xiàng)B更便宜，選項(xiàng)C更廣泛，都無關(guān)，屬于常識(shí)性干擾。

　　24. 答案【D】an unreasonable price for enrollment.

　　解析：本題目為具體細(xì)節(jié)題。根據(jù)題干關(guān)鍵詞problem with the PreCheck program定位到倒數(shù)第二段的第二句話 this price tag has been the PreCheck’s fatal flaw.本句中的代詞this代詞指代本段第一句話，說的是Passengers必須每五年pay 85美元來做background checks。正確答案D中的unreasonable price 是原文的85美元，enrollment就是原文的process background checks。干擾項(xiàng)A其規(guī)模的極具下滑未提及，選項(xiàng)C其錯(cuò)誤的執(zhí)行屬于過度推理，選項(xiàng)C政府不愿意支持是對(duì)原文的曲解。

　　25. 答案【C】Getting Stuck in Security Lines

　　解析：本題目為全文主旨題。全文的中心主題出現(xiàn)在第一段和二段首句的范圍。第一段介紹事實(shí)背景，第二段首句提及了美國(guó)人對(duì)于安全檢查方面的狀況，并在下文提及了所出現(xiàn)的問題。正確答案C安檢流程線陷入困境是對(duì)原文的總結(jié)概括。干擾項(xiàng)A的Screening 是原文的具體細(xì)節(jié)，選項(xiàng)B和選項(xiàng)D的PreCheck是原文最后三段的內(nèi)容。
