Question

从句中什么时候用when/ where which/that?
就像Do you still remember the days (when) we spent together last summer?这个句子 缺宾语 所以不能用which/that对么?做主语时呢?

Answer 1

你在此询问的是关于引导定语从句的关系词when/ where/ which/that的用法.
1.which/that指物,可作主语或宾语,作宾语时可省略.此外,that还可指人.
2.当先行词为时间,且在定从中作时间状语时,用when.
I still remember the day when I first came to this school .
3.当先行词为地点,且在定从中作地点状语时,用where.
We visited the factory where my father works last week .
Do you still remember the days ( ) we spent together last summer?
此句不能用when,而可以用which/that,也可省略which/that,什么都不用.
因为spent为及物动词,它必须带宾语,所以只能用which/that作宾语,并引导定从.
when在定从中作时间状语,而此句需要的是宾语,因此不能填when.
