11 OG 88~~请教大家！~~：）

88. The recent surge in the number of airplane flights has clogged the nation's air-traffic control system, to lead to 55 percent more delays at airports, and
            prompts fears among some officials that safety is being compromised.

(A)            to lead to 55 percent more delays at airports, and prompts

(B)           leading to 55 percent more delay at airports and prompting .

(C)           to lead to a 55 percent increase in delay at airports and prompt

(D)           to lead to an increase of 55 percent in delays at airports, and prompted

(E)           leading to a 55 percent increase in delays at airports and prompting

Parallelism + Diction

The intent of the sentence is to show two effects of the surge in flights. These effects should be stated in parallel ways, instead of the construction to lead ... and prompts ... used in the original sentence. Using participial phrases introduced by leading and prompting solves this problem. The phrase 55 percent more delays is not as clear as the phrase a 55 percent increase in delays.

A         To lead and prompts are not parallel; 55 percent more delays is not clear

B          55 percent more delay is unclear

C         To lead and prompt are not parallel; the

meaning of increase in delay is not clear

D          A participial phrase introduced by leading

is preferable to the unclear infinitive phrase

to lead to; an increase of 55 percent in delays is

awkward and wordy

EE   Correct. Leading and prompting are parallel in this sentence; the phrase a 55 percent increase in delays is clear      .. _

The correct answer is E.

请问C选项怎么错了？？prompt前省略to很正常啊~~答案说increase in delay不清楚，可是他的结构跟位置和E选项完全一样，C与E不同的地方就是平行结构的用法不一样~~请大家指教！欢迎讨论！：）

希望会解答的NN能看得见！！！~~~

分词作状语一般表示伴随，而不定式做状语常常表示目的。

根据句子意思，用分词符合逻辑，ＥＴＳ的解释我也不明白

1.这是以前NN关于delays的解释Choice C uses the singular delay where the plural is needed to indicate an increase in the number of delays; the phrase increase in delay has no exact meaning.

2.另外如果prompt前不加to,会不会导致将prompt翻译为形容词呢？

3.ETS似乎没有否定使用不定式。

强人，分析得比较透彻！~~这个题看来只有按伴随状语解释~~ing分词引导~~

感谢xfwxiao引用的第一条NN的解释，刚好解决了我的问题。

PS:在这里是做状语的，所以to lead。。。是错的，应该用leading。。。
