[求助]OG11（紫）SC 39 [than后面的省略问题]

39. A study commissioned by the Department of Agriculture showed that if calves exercise and associated with other calves, they will require less medication and gain weight quicker than do those raised in confinement.

A. associated with other calves, they will require less medication and gain weight quicker than do

B. associated with other calves, they require less medication and gain weight quicker than

C. associate with other claves, they required less medication and will gain weight quicker than do

D. associate with other calves, they have required less medication and will gain weight more quickly than do

E. associate with other calves, they require less medication and gain weight more quickly than

我选E，根据associate排除A和B， 然后根据require,gain选择E。

我的疑问是，为什么这里的than后面的do要去掉，一直对than后面要不要去掉do, will, is等很疑惑。

还有两周不到就考试了，请教！！ 谢谢！！

不是NN,

我觉得这里do指代歧义，因为前面有两个谓语动词(require & gain),所以此处不用更好一些

OG解释的the verb do ungrammatically interrupts the comparison and should be eliminated很晦涩.

根据新东方老师说的,后面的助动词要是补的话一定要补对,否则即使是补上了也是错的,在其他选项的助动词都补错的情况下,没有补上的也可以算对:

比如该题 A study commissioned by the Department of Agriculture showed that if calves exercise and associate with other calves, they require less medication and gain weight more quickly than those raised in confinement (do)

这里的do补上更好,不补也不算错,有补对的就选那个,但是如果补成 have, be, will等那么都算错

这应该算是个effectiveness error

the verb do ungrammatically interrupts the comparison and should be eliminated.

disagree,这里do不应当补,以OG为准.

1 这句话即使补也是补will，不是do吧？

2 than前面有两个或两个以上动词，不补（没记错的话应该是白勇语法说的）

假设我们把gain去掉，那么显然这个句子必须补出will

这道题答案是E， 没有will在其中阿。

OG后面的解释我也看了，说do导致歧义， 不理解。。。

不好意思啊 我之前把A选项里的will当作未划线部分了

这道题不补出助动词就是因为前面有2个动词而已
