He never hesitates to make ______criticisms________are are considered helpful to others.

问题描述:

He never hesitates to make ______criticisms________are are considered helpful to others.
A.such ,which B.such ,as
为什么选A不选B
as 后可以加谓语

选B的话as后面需要接一个有主语的句子,而显然这个句子没有,而which作为先行词引导的定语从句可以直接接谓语,故选B
哎 我没说as后不能接谓语啊 as可以接 但是你要看到这里是一个such...as短语引导的主从复合句!在这里,as不能直接用,你看后面的从句缺少一个主语啊
