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.
- the cost of which raises water bills high enough so that
- at a cost raising water bills so high that
- at a cost which raises water bills high enough so
- whose cost will raise water bills so high that
- whose cost will raise water bills high enough so that
答案是D,我选的是B,看了前人的讨论。还是不明白B有什么错误,是不是B得悉惯用法都是:At a cost of +...$阿?没有单独用来链接后面raising的情况?
whose 可以修饰物。怎么这么怪阿
请帮忙分析一下谢谢! |
