搜索了一下好像没有人讨论过这个题,也许比较简单吧,NN们不要见怪~ The recent surge in the number of airplane flights has clogged the nation's air-traffic control system, to lead to 55 percentmore delays at airports, and promopts fears among some officials that safety is being compromised. B. leading to 55 percent more delay at airports and prompting E. leading to a 55 percent increase in delays at airports and prompting 正确选项是E, 其中对B的解释是a 55 percent increase in delays 比 55 percent more delay清楚,请问清楚在哪里呢? |
