OG11-88

antiquarks

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

Ans:E

1.C 除了-ing錯了以外 , delay少一個S 句意上有何差別？？
2.an increase of 55 percent in delays 和 a 55-percent increase in delays差別在哪？
為何OG說an increase of 55 percent in delays is awkward and wordy
3.OG解釋A To lead and prompts are not parallel , 可是平衡 to + V , and V 不是有這樣的用法嗎？為何OG會說不平衡

麻煩各位了

从牛津在线字典上查到的：

increase『verb [I or T]』： to (make something) become larger in amount or size

这里如果delay用单数，那么句意变成: The recent surge in the number of airplain

flight...,making delay become larger in size. 前面说的是数量，但是后面增加的变成size，不合逻

辑。所以要用delays。

to lead...不是不定式，是介词短语，但是这个介词短语的修饰对象不明确，逻辑上应该当状语修饰has

clogged，但是可能存在做定语修饰前面的system，改成分词短语明确修饰has clogged。

我觉得 to + v, and v  是可以的，但是这里是 to lead, and prompts , 不是动词原形
第二题很不懂，请指教

antiquarks

想了一下
这边 to 因该介词 后面接N
致于delay ,  和 delays
因该是因为 前面 a 55 percent increase 的关系 ,增加的delay,因该会是多数

本题的to不是不定式!

表达方式的问题。强行记忆或者多点英语培养语感！

carollai

leading和prompting都是表结果

to lead和to prompt表目的，句意错了
