定语从句中在哪些情况下用关系副词?
问题描述：
定语从句中在哪些情况下用关系副词?
*I will never forget the day when I first met you on the seashore.
*I will never forget the days which/that we spent together in Xueyao Middle School.
为什么上句用when而下句用which?
**This is the hospital where my mother works.
**This is the hospital which/that we visited the day before yesterday.
***The reason why he did not go to school is that he was ill.
***This is the reason which/that he gave his boss in the office .
还有这四句,为什么不用相同的词引导?
关系副词都可换成“介词+关系代词”的形式吗？
答
其实很简单
关系词的选择跟从句中是否缺少相应成分有关
如果从句缺少主语或者宾语,则需选用关系代词充当相应成分
如果从句的结构完整,则选用关系副词作状语
比如前两句：
1.I first met you on the seashore是一个完整句子,用副词when
2.we spent 】together in Xueyao Middle School缺少宾语,用which
其他的道理一样
自己体会下!
