The day when we met last week为什么用when不用that

Answer 1

问：The day when we met last week为什么用when不用that

答：您好！很高兴为您解答！您意思是The day that we met last week？

答：如果引导词需要在定语从句中作时间状语,使用when,如果已经有时间状语,则用that 或which.

答：when we met last week.是由when引导的定语从句

答：the day在从句中为时间状语成分

答：再比如比如 the days ____ we studied together 此时the days在从句中应为时间状语的成分(we studied together in the days),故引导词用when](此时的when可相当于用the days in which we studied together或the days which we studied together in)

答：比如 the days ____ we spent 此时the day作从句中spent的宾语(we spent the days),引导词就用that(用which也可以)

问：倒数第二条信息中最后一段英语为什么关系词是which?

答：那里是说when相当于the days which we studied together in

答：并不是说the days ____ we studied together 这里用which
