HELP ME GWD-7-15

Q15:

The city has proposed a number of water treatment and conservation projects the cost of which raises water bills high enough so that even environmentalists are beginning to raise alarms.

1. the cost of which raises water bills high enough so that
2. at a cost raising water bills so high that
3. at a cost which raises water bills high enough so
4. whose cost will raise water bills so high that
5. whose cost will raise water bills high enough so that

答案D   WHOSE引导的从句不是只可以跟在人的后面吗?

B选项中raising修饰cost哪出错啦?

NN指点

whose 人和物都可以跟的

另外at a cost....你不觉得很awkward吗？

常用的是　at the cost of (以．．．为代价)

D很有逻辑的交代了cost will .......非常的明了

不知解释清楚了没？

看来关键还是whose的用法

那WHO是不是和WHOSE一样可以代物呢?

人－he,she,who,whom

物－it , that, which

人＋物－whose
