please call me before leave 这句子对吗
问题描述：
please call me before leave 这句子对吗
答
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
答
Please call me before leaving
答
不对，before后面要么跟从句，要么跟动名词，跟动词原形算什么
答
before是介词，后面要加动词的ing 形式，所以是 leaving
答
可改为：
Please call me before you leave.
Please call me before your leaving.
Please call me before leaving.
答
应该是 Please call me before leaving 才对
答
错了 ,缺少谓语 please call me before {you } leave 你离开之前请打电话给我
答
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
