急问GWD-20-15!!<没讨论过>

crossover45

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                                                                                              

   这题答案是D，我选B。答案怎么会是D呢? Whose指project应该要用which吧?看得我莫名奇妙。请NN指点吧!

B is incorrect.

1:raising water billing修饰 cost, raising这个现在分词，使raising有正在进行的意思，意思上说不通。

2:用whose，意思是工程的费用使水费增减。而用which，意思是工程使水费增加。

谢谢你，经你这么一说，我也觉得B的raising不太对。但是whose是指project是不是不太对呢?我记得whose只能指代人的所有格。

Sorry. Whose should refer to "water treatment and conservation projects"

补充一点，raising这个现在分词不是表正在进行，而是一般现在时省略主语后用现在分词形式引领分词从句

D? how come D

I think it should be B

is there any explaination by chance????

现在再回来看这一题，我还是支持B。at a cost raising water bills so high that中的raising应该是at a cost that raises water bill的分词形式，省略that, raising改成分词修饰cost。D的whose怎么看都觉得不爽。还请NN给我点意见

i choose between D and E, but why E is not correct?

我也不懂啊，求NN，10号就要考了

我的理解是这里的cost应该有定冠词the或物主代词限定表示特指，B,C表示泛指,而且一般用at XXX cost of...
