标题Re: [问题] ov-108

您的两个问题如下,我也用 OV 後面的解释回覆会更精确:
1. 为什麽C的from後面可以用主动,energy会主动做dissipating的动作吗
OV 解释: Dissipating is not a transitive verb (并非及物动词)
您说对了,energy 必须要主动作 dissipating 的动作
2. 为什麽as a result of 不行?
如果真的想表示藉由boundaries
不是应该用through +N或by+Ving吗
还是说by後面接什麽都可以?
我认为,当文法不容易看出错误的时候,必须要先看句意的部分:
OV 对整题的解释:
water layers (等同於 boundaries) in the ocean
prevent acoustic energy from dissipating.
(D) its acoustic energy
prevented from being
dissipated
as a result of (boundaries)
OV 对此选项解释:
being dissipated as a result of makes it unclear whether the
boundaries contribute to energy loss or prevent it.
如果如 (D) boundaries 放在 as a result of 後面,
则 boundaries 可能为 "prevented from" 的主词 (此题正确句意)
或 "disspipated" 的主词 (和本句相反的句意)
(C) 的 by 必定指向 "prevented from",而没有如此的问题发生。
不过我想,其实主要是说,可以当主动的动词 (如 (C) 表示),
硬要用被动表示 (如 (D) 表示),相对也比较不好就是了。

1F:推 qctm: 谢谢~可是那请问为什麽by必定指向prevented呢? 01/24 17:54
(C) 的动词是使用主动的用法,"dissipating",
很明确指出做这动作的必定是主词 "its acoustic energy"
所以 by 当然指向使用被动的动词 "prevented from" 了
2F:→ qctm: 哇恩恩好清楚谢谢~ 01/24 18:09
