定语从句中“介词+关系代词/副词”中介词是如何确定的
定语从句中“介词+关系代词/副词”中介词是如何确定的
定语从句中“介词+关系代词/副词”中介词是如何确定的
系副词即表时间when,地点where ,原因why,等词,在句中的具体用法要看句子的意思了.介词加关系代词一般情况下就是介词加which的情况,即in which = where/when (大的时间年月季等或大的地点国家、城市等) at which=where/when(小的时间点 某一时刻 或小的地点 在学校、家等) for which=why 因此,在定语从句中,有介词时,必选which,其意与所对应的关系副词是一样的.
还要根据句子的结构搭配哦
选用介词的依据：
(1) for which=Why
Yesterday we visited the West Lake for which Hangzhou is famous.
(2) with whom和某人
The old woman with whom you talked just now is a famous artist.
(3) through which穿过某处
The naughty boy made a hole in the wall through which he could see what is happening outside.
(4) 表示“所有”关系或“整体中的一部分”时,通常用介词of.例如：
I have about 20 books,half of which were written by Bing Xin,the famous writer.
(二)在定语从句中,含介词的短语动词不可拆开使用(短语拆开后含义发生变化),如look after,look for等.例如：
The babies whom the nurses are looking after are very healthy.(正)
The babies after whom the nurses are looking are very healthy.(误)
【三】“of which / whom”有时可以用“whose＋名词”结构来改写.例如：
The building whose roof was damaged in the earthquake has been repaired.
＝The building of which the roof was damaged in the earthquake has been repaired.
好了,报告完毕.
这个有前搭配和后搭配。
前搭配就是根据前面的先行词来确定，。eg:the direction in which they come (come in the direction)
后配就是定语从句中固定短语的介词 eg:this is a house in which we live( live in the house)
在定语从句中，“关系副词=介词+关系代词”，介词的选择取决于该介词与定语从句的先行词或从句中的谓语动词的搭配。
根据前面的先行词确定，一般介词都会和先行词形成一个完整的对应短语。
比如 We live in the world
用定从时就成了 the world in which we live
关键是介词和先行词对应好！！！
大概就是这样，有时候也要根据具体情况讨论！~~
不明白的还可以问我哦~~...
