please call me before leave 这句子对吗
please call me before leave 这句子对吗

please call me before leave 这句子对吗
错了 ,缺少谓语 please call me before {you } leave 你离开之前请打电话给我

before是介词,后面要加动词的ing 形式,所以是 leaving

应该是 Please call me before leaving 才对

please call me before leave 这句子不对
应该是 Please call me before leaving 才对
before是介词,后面要加动词的ing 形式,所以是 leaving

不对,before后面要么跟从句,要么跟动名词,跟动词原形算什么

可改为:
Please call me before you leave.
Please call me before your leaving.
Please call me before leaving.

不对hope sb to do sth 改为:I hope you to call me . 而before后跟动词时则跟动名词,此句后跟名词就不用考虑这一点了,也可改为: before

Please call me before leaving
