个人觉得这句话是宾语的比较,就是Know之后的部分来做比较,一般来说宾语比较是可以省略谓语动词的,但是可以不代表必须省略,原则就是不能造成歧义或者语义不清,本句没有省略,我想可能是因为前面的know (a great deal) more没有明确的名词可以让than之后完全省略主谓还能表达清晰的意思。例如,I have more books than pens. I have 就可以省略了。 本题不是状语比较,否则than now就没有问题了。 另外一道你问的题应该是状语的比较,状语比较的时候,主谓一致可以省略。 -- by 会员 ScentyGuy (2011/12/6 16:46:09)
OG这个题不能省,是不是因为would have to know和know不是一种时态什么的,所以不能省略?? |
