She can't sleep well before she ______takes an exam .before是介词,take 为什么不加ing
因为before后面的she takes an exam是一个完整的从句,所以当然不加ing.如果只是动词短语,那么必须加ing ,如:
She can't sleep well before taking an exam .

要是答案还满意的话,记得采纳哦,O(∩_∩)O谢谢~!

before 在此是连词,在...之前,后面接的是一个句子,而不是直接接的动词,所以不用ing形式。

如果中间没有那个she就加ing

before在这里是连词
