before (C) 译为“在。。。之后”before 的一个用法。
全句的意思是。给他说了我新家的地址之后,我又告诉他我把钥匙放在了门前的)擦鞋垫下面。我知道如果我回去的话,那就太晚了。注意以下第四种用法。
before作连词用
1. 表示"在......之前",引导时间状语从句,可放在主句之前或之后,但通常不用于一般将来时。例如:
Do it now before you forget. 现在就做,免得你忘了。
I had read the operation instruction before I began to test the machine. 开始试验该机器之前,我已看过操作说明书了。
2. 表示"过了多久才......"、"......之后才......",常用于"It is (will be, was...) + 时间段 +before +S. + V. +..."句型。例如:
It will be three years before we meet again. 三年之后我们才能再见面。
3. 表示"不多久......就......",常用于"It is(was) not +时间段 +before +S. + V. +..."句型。例如:
It wasn't long before she told me about the affair. 过了不多久她就把这件事告诉我了。
4. 表示"不等......就......"。例如:
Before I could get in a word he had measured me. 不等我插话,他已经给我量好了尺寸。
5. 表示"先......再......"。例如:
Be a pupil before you become a teacher. 先做学生,再做先生。
6. 表示"宁可......也不......"。例如:
