OG12 verbal分册 sc108

108.Sound can travel through water for enormous distance, prevented from dissipating its acoustic energy as a result of boundaries in the ocean created by water layers of different temperatures and densities.这道题正确答案是：its acoustic energy prevented from dissipating by.
我对这道题的OG上有关这道题的D解释很不理解：
D选项：its acoustic energy prevented from being dissipated as a result of.
OG解释：the version of the sentence is wordy, awkward, and indirect; being dissipated as a result of makes it unclear whether the boundaries contribute to energy loss or prevent it.怎么就不清楚了？怎么看都还是boundaries 阻止了energy 的消散啊。。。。


能有NN解释一下啵？谢谢！

LZ，你确定你这个题是OG12，SC的108题？难道咱们两本书的题号不一样？

额，我发现我漏写了两个字。。。。。是verbal分册。。。。。。。童鞋。。。先帮忙解个题啊。。。。

OG里的解释有一段是说dissipate这个词是个VI，没有被动也不能接宾语，所以直接从语法上就排除了。。词典里的英译to cause to separate and go in different directions也很明确的说明这是个VI。。
不是NN。。希望能帮到你。。我也刚看到这道题。。

我也对as a result of的用法有疑问，求助啊！

我是这么理解的，prevented 和 dissipating都为分词，显然有着不同的逻辑主语，就是动作发出者，prevented是过去分词，那它的逻辑主语一定就是by boundaries的这个boundaries。dissipating为现在分词不表示被动，那它的逻辑主语就是 acoustic energy，修饰说明了energy的状态。所以这句话的逻辑顺序是 boundaries prevent  energy from dissipating.

再来看D选项，prevented和being dissipated 都是表示被动，那它们逻辑主语一定都不是 acoustic energy了，那么它们的逻辑主语就应该是 boundaries
所以，这就有了矛盾，boundaries prevent  energy 还是 boundaries dissipate  energy?

OG给的解释还是很有道理的。

谢谢LS，明白啦，与B的错误差不多(B) prevented from having its acoustic energy dissipated byog解释：B This version of the sentence is wordy,
awkward, and indirect; from having... by erroneously suggests that the boundaries in the ocean are attempting to dissipate sound energy.


因为B的having..dissipated by和D的being dissipated都有被动的含义，所以by boundaries和as a result of boundaries都可以修饰这个成分，也可修饰prevent，所以就不知道到底是prevent了还是dissipate了。


谢谢LS，没太看到这块，总是纠结在as a result的用法上了。另，ron关于as a result 和 by的区别供大家参考：


"as a result of" doesn't make sense, because (as you can discern from context) the energy is actually prevented from dissipating BY the boundaries.

"as a result of" suggests indirect causation. i.e., when you write “x happened as a result of y”, the implication is that y didn't cause x directly, although y was in some way ultimately responsible for x.

e.g.
if 500 people actually died IN an explosion, you could write
500 people were killed by the explosion.

on the other hand, if some or all of these people didn't actually die in the explosion itself, but died from other causes related to the explosion -- e.g., the explosion released carbon monoxide, which ultimately killed them later -- then that sentence would be inaccurate. in this case, you could write
500 people were killed as a result of the explosion.

我想论证一下OG对D的解释：“as a result of ...” 作为一个副词，可以修饰句子中的动词。但是句中有两个动词（虽然处于不同语态）prevented和being dissipated，那么问题来了，“as a result of ”到底修饰哪个动词呢？所以OG会说as a result makes it unclear whether the boundaries contribute to energy loss or prevent it.
