10、0 points ）Text 1First two hours,now three hoursthis 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
11、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
12、 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 weaponsboth fake and realpast airport security nearly every time they tried.Enhanced se
13、curity 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 Chicagos OHare International.It is not yet clear how much more effective airline security has becomebut the lines are obvious.Part o
14、f 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 carr
15、y-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 wh
16、o 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:Passe
17、ngers must pay$85 every five years to process their background checks.Since the beginning,this price tag has been PreChecks 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
18、 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.21.The crash of Egypt Air Flight 804 is mentioned toAexplain Americans tolerance of current sec

22、wrote Queen Liliuokalani,Hawaiis last reigning monarch,in 1897.Star watchers were among the most esteemed members of Hawaiian society.Sadly,all is not well with astronomy in Hawaii today.Protests have erupted over construction of the Thirty Meter Telescope(TMT),a giant observatory that promises to r
23、evolutionize humanitys view of the cosmos.At issue is the TMTs planned location on Mauna Kea,a dormant volcano worshiped by some Hawaiians as the piko,that connects the Hawaiian Islands to the heavens.But Mauna Kea is also home to some of the worlds most powerful telescopes.Rested in the Pacific Oce
24、an,Mauna Keas peak rises above the bulk of our planets dense atmosphere,where conditions allow telescopes to obtain images of unsurpassed clarity.Opposition to telescopes on Mauna Kea is nothing new.A small but vocal group of Hawaiians and environmentalists have long viewed their presence as disresp
25、ect far sacred land and a painful reminder of the occupation of what was once a sovereign nation.Some blame for the current controversy belongs to astronomers.In their eagerness to build bigger telescopes,they forgot that science is not the only way of understanding the world.They did not always pri
26、oritize the protection of Mauna Keas fragile ecosystems or its holiness to the islandsinhabitants.Hawaiian culture is not a relic of the past；it is a living culture undergoing a renaissance today.Yet science has a cultural history,too,with roots going back to the dawn of civilization.The same curios
27、ity to find what lies beyond the horizon that first brought early Polynesians to Hawaiis shores inspires astronomers today to explore the heavens.Calls to disassemble all telescopes on Mauna Kea or to ban future development there ignore the reality that astronomy and Hawaiian culture both seek to an
28、swer big questions about who we are,where we come from and where we are going.Perhaps that is why we explore the starry skies,as if answering a primal calling to know ourselves and our true ancestral homes.The astronomy community is making compromises to change its use of Mauna Kea.The TMT site was
29、chosen to minimize the telescopes visibility around the island and to avoid archaeological and environmental impact.To limit the number of telescopes on Mauna Kea,old ones will be removed at the end of their lifetimes and their sites returned to a natural state.There is no reason why everyone cannot
30、 be welcomed on Mauna Kea to embrace their cultural heritage and to study the stars.26.Queen Liliuokalanis remark in Paragraph 1 indicatesAher conservative view on the historical role of astronomy.Bthe importance of astronomy in ancient Hawaiian society.Cthe regrettable decline of astronomy in ancie
31、nt times.Dher appreciation of star watchers feats in her time.27.Mauna Kea is deemed as an ideal astronomical site due toAits geographical features.Bits protective surroundings.Cits religious implications.Dits existing infrastructure.28.The construction of the TMT is opposed by some locals partly be
32、causeAit may risk ruining their intellectual life.Bit reminds them of a humiliating history.Ctheir culture will lose a chance of revival.Dthey fear losing control of Mauna Kea.29.It can be inferred from Paragraph 5 that progress in todays astronomyAis fulfilling the dreams of ancient Hawaiians.Bhelp

34、nce said that a countrys GDP measures“everything except that which makes life worthwhile.”With Britain voting to leave the European Union,and GDP already predicted to slow as a result,it is now a timely moment to assess what he was referring to.The question of GDP and its usefulness has annoyed poli
35、cymakers for over half a century.Many argue that it is a flawed concept.It measures things that do not matter and misses things that do.By most recent measures,the UKs GDP has been the envy of the Western world,with record low unemployment and high growth figures.If everything was going so well,then
36、 why did over 17 million people vote for Brexit,despite the warnings about what it could do to their countrys economic prospects?A recent annual study of countries and their ability to convert growth into well-being sheds some light on that question.Across the 163 countries measured,the UK is one of
37、 the poorest performers in ensuring that economic growth is translated into meaningful improvements for its citizens.Rather than just focusing on GDP,over 40 different sets of criteria from health,education and civil society engagement have been measured to get a more rounded assessment of how count
38、ries are performing.While all of these countries face their own challenges,there are a number of consistent themes.Yes,there has been a budding economic recovery since the 2008 global crash,but in key indicators in areas such as health and education,major economies have continued to decline.Yet this
39、 isnt the case with all countries.Some relatively poor European countries have seen huge improvements across measures including civil society,income equality and environment.This is a lesson that rich countries can learn:When GDP is no longer regarded as the sole measure of a countrys success,the wo
40、rld looks very different.So what Kennedy was referring to was that while GDP has been the most common method for measuring the economic activity of nations,as a measure,it is no longer enough.It does not include important factors such as environmental quality or education outcomesall things that con
41、tribute to a persons sense of well-being.The sharp hit to growth predicted around the world and in the UK could lead to a decline in the everyday services we depend on for our well-being and for growth.But policymakers who refocus efforts on improving well-being rather than simply worrying about GDP
42、 figures could avoid the forecasted doom and may even see progress.31.Robert F.Kennedy is cited because heApraised the UK for its GDP.Bidentified GDP with happiness.Cmisinterpreted the role of GDP.Dhad a low opinion of GDP.32.It can be inferred from Paragraph 2 thatAthe UK is reluctant to remold its
43、 economic pattern.Bthe UK will contribute less to the world economy.CGDP as the measure of success is widely defied in the UK.Dpolicymakers in the UK are paying less attention to GDP.33.Which of the following is true about the recent annual study?AIt excludes GDP as an indicator.BIt is sponsored by
44、163 countries.CIts criteria are questionable.DIts results are enlightening.34.In the last two paragraphs,the author suggests thatAthe UK is preparing for an economic boom.Bhigh GDP foreshadows an economic decline.Cit is essential to consider factors beyond GDP.Dit requires caution to handle economic issues.35.Which of the following is the best for the text?AHigh GDP But Inadequate Well-being,a UK lesson
