which引导定语从句时能否用复数？

Question

如题所述

Answer 1

这个问题好像存在好久了，说下自己的看法吧。 仅供参考。

which在非限制性定语从句中，用来指主句内容。

He made noise in class, which made his teacher angry.
这个句子其实= He made noise in class and it/ that made his teacher angry.
显然it或that, 应该指上文发生的事情，或上文的情况。这里表现的比较含糊，没有数量之分，所以我觉得which后面不能用复数谓语动词。

上面一个句子改成：He often makes noise and sleeps in class, which makes his teacher angry.
这里我觉得还是用单数谓语动词。
改成He often makes noise and sleeps in class and it/that makes his teacher angry.
不能说He often makes noise and sleeps in class and they/those make his teacher angry.
显得不伦不类。
