个人意见，我觉得A当中they指代不清楚，一般我们可以认为是they解释为children，但是spend得主语也可以是物的相当于take ,所以这里的they会使人感觉指代chores。

本题为什么不选A？

这里的A B,都是过去分词作句末，有2个意思，1，是就近修饰名词，还有就是逻辑主语是主句的主语，构成被动状态，所以AB的意思都是不对的，应该根据A感觉应该是海中的分界限阻止逻辑了ACOUSTIC ENERGY。所以选C最好因为同位语结构，n+过去分词，表示伴随结果。

D中的being累赘

E中的prenenting逻辑主语是主句主语或者是表示主谓的伴随状态，但是也不对，这里的prevent的主语应该是by后面的分界线。。改变句意。

不是说逗号不能连接两个独立的句子么？

yankevi

没有句子啊。。如果是句子，那应该是its acoustic energy（is） prevented from dissipating by。

这里是同为语结构。。所以不能有独立的谓语

eg： i read the book,it on my knee.

rogerjie

zhangxq

Sound can travel through water for enormous distances, prevented from dissipating its acoustic energy by boundaries in the ocean created by water layers of differing temperatures and densities.

我在the new york times 上找到的原句。有一点出入，但是我觉得可以和A 中的as a result of 替换的。A应该没错的。

个人觉得GMAC的出题就是找最合适的，记得prep破解版中论语法等都没有错误，但是gmac就是喜欢以主动优先被动，以同位语从句优先一般的从句或者时态。至于这题到底选什么，个人意见，还是C
