Do you remember last summer , when angry travelers were urging the government to do something about airline customer service ? Airlines     36     to improve , and they adopted (采用)new standards just before Christmas .    37     as another summer nears , plenty of     38 travelers don’t see much improvement in customer     39     overall . This month , the Department of Transportation’s (DOT) office will publish its first critical   40 on whether airlines are     41     their promises . One survey（调查）suggests problems : the number of     42     to the DOT about the top 10 airlines in the first     43     rose 89% from a year ago .

The “12 promises” to passengers were introduced     46     a mjor effort to improve service . Since then , airlines have been redesigning websites , retraining employees and upgrading technology . Recently , DOT inspector general Kenneth Mead , at McCain’s request , sent 20 examiners to airports to     47     whether each airline is doing what it promised . Mead warns travelers shouldn’t    48      too much . Most of the promises are    49      better communication with customers , not problems with flights . “Passengers should show more understanding to airlines about their     50     to better air service .” Spokeswoman Shelly Sasson says . “And when     51     are made , it takes a long time for them to be noticed,” she says . Now , the efforts may be working . During the first quarter , Delta had the second-lowest rate of complaints among the     52     10 carriers .    53     , its rate , along with other carriers’ , is up from last year . McCain and other lawmakers say there may be  a     54     to pass new consumer-protection      55    . 36．A．promised                      B．managed                C．hoped                    D．refused 37．A．So                         B．But                        C．Merely                   D．Even 38．A．skilled                   B．experienced            C．tired                             D．puzzled 39．A．flight                     B．opinion                  C．service                   D．travel 40．A．news                     B．information            C．doubt                     D．article 41．A．honoring                B．making                  C．giving                    D．improving 42．A．problems                      B．travelers                 C．passengers              D．complaints 43．A．quarter                  B．year                       C．month                    D．summer 44．A．customer                B．company                C．government            D．public 45．A．wished                   B．agreed                    C．remembered           D．failed 46．A．to                          B．for                        C．as                          D．by 47．A．explain                   B．discuss                    C．discover                 D．check 48．A．travel                    B．expect                    C．complain                D．suggest 49．A．aimed at                B．considered as          C．joined to                D．made from 50．A．difficulty                      B．situation                 C．reality                    D．efforts 51．A．suggestions            B．rules                      C．decisions                D．improvements 52．A．large                     B．first                       C．top                        D．bad 53．A．Still                       B．Therefore                C．Instead                   D．Meanwhile 54．A．possibility              B．need                      C．chance                   D．use 55．A．examinations          B．service                   C．laws                      D．reports
