OG Vebral分册的一道题
As a result of record low temperatures, the water pipes on the third floor froze, which caused the heads of the sprinkler system to burst, which released torrents of water into offices on the second floor.
A) which caused the heads of the sprinkler system to burst, which released torrents of water
B) which caused the heads of the sprinkler system to burst and which released torrents of water
C) which caused the heads of the sprinkler system to burst, torrents of water were then released
D) causing heads of sprinkler system to burst, then releasing torrents of water
E) causing heads of the sprinkler system to burst and release torrents of water
答案选E
对于D选项OG给的解释是the structure of this version makes the freezing of the pipes the subject of both causing.... and releasing....The introduction of the sequential maker then devides the brusting of heads and releasing of torrents of water into two seperate events in the sequence.It indicates,implausibly,that the pipes' freezing directly released torrents of water after it had also caused the sprinkler heads to burst.
我对解析的理解是,causing heads of sprinkler system to burst 和releasing torrents of water平行修饰the water pipes on the third floor froze,可是没有and,用then也可以吗?
可是又想起来 comma+v-ing是对前一句的修饰,那不就是修饰causing heads of sprinkler system to burst嘛……
凌乱了 求指教
感谢!
