15．An American airline won the right to weigh its passengers over a six-month period earlier this year to learn how it could save fuel，after discovering the average passenger and carry-on luggage was heavier than expected．
Hawaiian Airlines has now cancelled pre-booked seating for people flying the 2，600-mile route between Honolulu and the American Samoa．Instead，passengers will be assigned seats when they check-in to make sure weight is evenly distributed around the main cabin（主客艙）of the plane．The airline will keep at least one seat open per row or place children under the age of 13 in those seats．
Some passengers said the policy was discriminatory as it only affects people flying on one route，from Honolulu to Pago Pago，with most passengers being of Samoan descent．Samoans have among the highest rates of obesity in the world．
Six complaints have been filed with the US Department of Transportation since 29September，as reported by the Economist．The department ruled in favour of the new policy，with airline officials claiming an even distribution of weight could prevent a crash landing．
Hawaiian Airlines said it had conducted a voluntary，six-month passenger weight survey on the Pago Pago route，starting in February asking all passengers to be weighed along with their carry-on luggage．As a result，the airline cancelled seat pre-selection only on the American Sanoa route because the other flight routes surveyed，for example in Korea and Japan，showed no evidence of extra weight．
Hawaiian Airlines is not the first passenger carrier to make the move．It follows Samoa Air starting to weigh passengers in 2013．Uzbekistan Airways also began weighing passengers in 2015．

B．A child weighing 70kg can sit in the open seat per row on the flight between Honolulu and the American Samoa．
C．The policy that Hawaiian Airlines carried out had an effect on several flights．
D．Some passengers were against the policy that Hawaiian Airlines carried out．
26．What is the US Department of Transportation's attitude to some complaints about Hawaiian Airlines'action？A

分析 本文向我們介紹了為了了解如何節(jié)省燃油以及發(fā)現(xiàn)乘客和隨身攜帶行李的重量比預期要重，美國一家航空公司在今年早些時候的6個月內(nèi)有權對其乘客進行重量評估，這一政策引起了乘客和美國運輸部的不同看法．
解答 24．B；細節(jié)理解題．根據(jù)文中"after discovering the average passenger and carry-on luggage was heavier than expected．"（因為發(fā)現(xiàn)乘客和隨身攜帶行李的重量比預期要重）可知夏威夷航空公司決定取消檀香山和美屬薩摩亞之間航班的預定座位是因為他們想對乘客的體重進行權衡，故選B．
25．D；推理判斷題．根據(jù)文中"Six complaints have been filed with the US Department of Transportation since 29 September，as reported by the Economist．"（據(jù)《經(jīng)濟學家》報道，自9月29日以來，美國交通部共提出了六起投訴）可推斷出肯定是有一些乘客違反了夏威夷航空公司的政策，故選D．
26．A；細節(jié)理解題．根據(jù)文中"Six complaints have been filed with the US Department of Transportation since 29 September，as reported by the Economist．"（據(jù)《經(jīng)濟學家》報道，自9月29日以來，美國交通部共提出了六起投訴）可知美國運輸部對夏威夷航空公司行動的一些抱怨的態(tài)度是消極的．故選A．
27．C；詞義猜測題．根據(jù)劃線詞的后句話"It follows Samoa Air starting to weigh passengers in 2013．"（在2013的時候，薩摩亞航空開始對乘客進行重測量）可知劃線詞是指在登機前對其乘客進行重秤，故選C．
點評 本文考察學生的理解推斷能力以及細心程度，只要抓住文章的關鍵詞，采用尋讀的方法查找細節(jié)，就能找到正確答案．
