比较的问题.... 快考了..真心求教... - ChaseDream

我知道在做比较的时候要尽量补充..但是我发现一个很基本的问题就是什么时候补充谓语.

Researchers agreed that the study of new treatments for heart attack patients was extremely important but more research was needed to determine that balloon angioplasty preceded with ultrasound was or was not any better for heart attack patients than the balloon procedure by itself.

A. more research was needed to determine that balloon angioplasty preceded with ultrasound was or was not any better for heart attack patients than

B. more research was needed for determining whether or not balloon angioplasty preceded by ultrasound is any better for heart attack patients than is

C. that more research was needed to determine whether balloon angioplasty preceded by ultrasound is any better for heart attack patients than

D. that more research was needed to determine that balloon angioplasty preceded with ultrasound was any better for heart attack patients than

E. that more research was needed for determining that balloon angioplasty preceded by ultrasound is or is not any better for heart attack patients than is

答案是C. 对于答案没有问题..但是我决的在最后要不要补充BE动词能? 我们经常可以看到有的该错题就是 A does ....than B does..其中后边这个动词的补充经常是考点..所以我想知道什么时候要补充呀... 我们经常说A is taller than B........就不补充能...是因为是BE动词的原因吗....

1、一般来说，主语间的比较时要补动词，尤其时前面主语带的句子里有宾语时，如果不加动词会造成宾语和后面主语比较的歧义。

比如，A do sth better B do。这个时候如果B后面不补do的话，可能会引起sth和B进行比较的歧义。

而你所说的，A is taller than B，这个句子里是没有名词宾语的，因此不会有歧义，所以不用补。

2、还有两个动作或者两件事情发生的时间不一致时，要补动词。

我不是nn，不知道说得是否清楚。JJ讨论区有个770的NN总结了比较的用法，你可以去看看。
