题目内容：

麻烦好心人总结下定语从句time后用when引导的情况
这几份资料把我弄糊涂了
①当先行词为 by the time ,any time ,the way,every time,the first time ,the last time 时,关系词不用when而用that.或省略,但如果time前无修饰语,关系词用that when 均可
②在定语从句中,time 有很多意思
比如:I miss the time when we were together.
It's the second time that I have seen the picture.
第一句中time表示"时间,时候",第二句time就表示"次"
③when引导定语从句表示时间[注]值得一提的是,表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导.
By the time when you arrived in London,we had stayed there for two weeks.
到你到达伦敦的时候,我们在那里已经待了两个星期.
I still remember the first time when I met her.
我仍然记得我第一次见到她.
Each time when he goes to business trip,he brings a lot of living necessities,such as towels,soap,toothbrush etc.
每一次他去出差,他带来了生活必需品,如毛巾,肥皂,牙刷等,很多.

首先要搞清楚 定语从句的定义：修饰一个名词或代词,相当于形容词；
引导词：关系代词：that; which; who; whom; whose; as
关系副词：when; where; why
做题技巧：定语从句引导词在从句中一定要充当成分；因此只要分析从句的句子成分,看需要,来确定关系代词或关系副词：即缺少主语或宾语则考虑关系代词,不缺主语或宾语则考虑关系副词.简言之：“做成分,看需要”.如：
I still remember the time _______ we spent together. (that/which)
此句定语从句中spent缺少宾语,故而考虑关系代词.
I still remember the time _______ we met. (when)
此句定语从句中不缺宾语,故而考虑关系副词.
I still remember the first time when I met her.
这句话中when i met her,定语从句用when 引导,与the first 无关,关键是看从句中的成分.
each time, last time, next time,是时间状语连接词,直接引导状语从句,如：
He said he had helped Jane each time he saw her.
他说他每次看见她的时候,都帮助了她.each time 不需 that, 又如：
Next time you come to my city, do drop in on me.
而 This is the first/second...time that sb. have/has done sth. 是固定句型,在讨论现在完成时的语法内应该有.如：
This is the second time that he has been late for class.
