Subway ridership is projected to increase by 20 percent over the next 10 years. The Metroville Transit Authority plans to increase the number of daily train trips by only 5 percent over the same period. Officials predict that this increase is sufficient to ensure that the incidence of delays due to crowding does not increase. Which of the following, if true, provides the strongest grounds for the officials’ prediction?
A. By changing maintenance schedules, the Transit Authority can achieve the 5 percent increase in train trips without purchasing any new subway cars. B. The Transit Authority also plans a 5 percent increase in the number of bus trips on routes that connect to subways. C. For most commuters who use the subway system, there is no practical alternative public transportation available. D. Most of the projected increase in ridership is expected to occur in off-peak hours when trains are now sparsely used. E. The 5 percent increase in the number of train trips can be achieved without an equal increase in Transit Authority operational costs.
求这道题完整的大意和,D的解释,我看到这道题有两个量,subway, trains ,他们之间的关系怎么回事啊? 最后一句话的does not increase 是什么成分,是修饰crowding 的么,due to 是最后一句话的谓语吗?谢谢好心人的帮助!作者: hughlv 时间: 2011-2-13 11:36
does not increase是修饰incidence of delays,due to crowding是修饰delays表原因。作者: sdcar2010 时间: 2011-2-13 11:37

D. Most of the projected increase in ridership is expected to occur in off-peak hours when trains are now sparsely used. 预计的乘客人数增长是发生在非高峰时段,由于现在火车已经很少作为交通工具。
文章的大意是:火车老是晚点,原因是乘客来不及下车。预计将来10年中还有20%的乘客人数增长。而有关部门认为在现有基础上增加个5%的班次应该能保证接下去至少晚点不会变得更严重。找支撑论据。作者: sdcar2010 时间: 2011-2-13 11:46
when trains are now sparsely used = when trains are now sparsely used by the riders.作者: jyw0411lsq 时间: 2011-2-13 11:51
这道题目说的train 和subway是一回事么,火车和地铁是两个东西啊~~~弱弱的问一下~作者: jyw0411lsq 时间: 2011-2-13 12:09
谢谢哈,明白了!作者: jyw0411lsq 时间: 2011-2-13 12:09
谢谢各位牛牛的解答,~~~作者: jyw0411lsq 时间: 2011-2-13 12:27 GWD6-Q33 对于这道题的讨论还挺多的,但是只有mindfree大牛的以下说法让我有点明白:Here all we know is that crowding is to blame for delay. So 20%ridership, is occurs only during off-peak time, will not cause crowdingproportionately (20% to 20%). Therefore 5% increase in trips might wellmitigate the problem.
但是我认为还需要再理清一下这道题的思路。 Premise 1Crowding 导致delay,于是Subway ridership is projected to increase by 20 percent. Premise 2 MT authority 打算增加20%班次,但车辆只增加5%。 conclusionOfficials predicts 这样做就可以解决由crowding导致的delay问题。
上面是引用一年前的解答,这里面怎么感觉出现问题了“,train trip, ridership, 到底对应什么啊,?班次,车辆,乘客的人数? 上面的竟然说:增加20%班次,增加5%的 车辆数, 这个矛盾了吗?( 见上面红笔)作者: sdcar2010 时间: 2011-2-13 13:04
ridership is not 班次, but the number of riders.
