答案是E,我选的B。 看了解释,可是还是不理解,为什么 The phrase 55 percent more delays is not as clear as the phrase a 55 percent increase in delays。
题意应该是航班延误率,或延误的航班数量增加,所以才用an increase of 55 percent in delays ,表示一个量的增长 但C中的...a 55 percent increase in delay at airports and prompt. 不清楚,不知道是使航班的延误时间增加了55%, 还是延误的航班数量。且它用的单数,如果可能则只可能指延误时间。而这只对一个航班才比较说得过去的。但可想而知,不太合理。因为既然影响到整个air-traffic系统,那就不止一个航班了,所以.....呵呵~
