OG 53，两个并列的介词短语省略

OG 53，请高人指点

OG 53.        There is no consensus on what role, if any, is played by acid rain in slowing the growth or damaging forests in the eastern United States.

(A) slowing the growth or damaging

(B) the damage or the slowing of the growth of

(C) the damage to or the slowness of the growth of

(D) damaged or slowed growth of（E）

(E) damaging or slowing the growth of

The corrected sentence must make clear that both damaging and slowing the growth of refer to forests. E is the only choice that does so without introducing errors. In choice A, of is required after growth. In choices B and C, the use of the damage instead of damaging produces awkward and wordy constructions, and without to after damage, B is grammatically incomplete. In C, the slowness of does not convey the original sense that the rate of growth has been slowed by acid rain. Choice D also changes the meaning of the sentence by making both damaged and slowed refer to growth.

两个并列的介词短语可以省略相同的介词吗？比如：the A of and B of = the A and B of，对吗？如可以E是否会有歧义?

damaging the growth of forest or slowing the growth of

or: damaging        forest or slowing the growth of forest

谢谢!

对不起,无法对上贴编辑.我想问的是:

两个并列的介词短语可以省略相同的介词吗？比如：the A of and B of = the A and B of，对吗？

如语法上对,对E的理解只有根据其逻辑意思了,对不?

首先，这里不是介词结构. 应该是个动宾结构.

其次, V1+N, V2+N, 可以将V1, V2用and, or等连词连接, 然后加上名词. 所以E里面damage后面省略的只是forests, 不是介词of.

对答案没有疑问,但是谁能解释一下这句话  In C, the slowness of does not convey the original sense that the rate of growth has been slowed by acid rain.  查了一下以前的讨论,都没有找到

slowness: 名词

slow: 动词

当把原文中的动词改成名词的时候要很小心, 因为somehow它改变了原文的意思.

role...in slowing...: 在slow这个动作(而且是进行中的)中所扮演的角色. 言下之意: 已经slow了.

role...in slowness...在"缓慢"(名词)中所扮演的角色. 是不是已经slow不知道, 只是说有这个能力让它slow.

恩,这下明白了

不好意思，给大牛提意见了。

看了薰衣紫草的解释，老觉得不是很顺：

slowness 呆滞；迟钝 noun

role in the slowness of the growth of forests 也许可以这么来理解：在具有缓慢生长率的森林中所扮演的角色。

如果这么理解是对的，那么就与原文企图表达的意思相右了：原文是想说明的是酸雨起到了减缓生长率的作用，而这里的缓慢生长率是否与酸雨有直接关系还挺模糊的。
