定语从句中介词+关系词
定语从句 知识讲解 “介词+关系代词”的用法
介词+关系词怎么用？介词加关系词分别等于什么？答：一、“介词＋关系代词”的用法当关系代词在定语从句中作介词宾语时，我们通常用“介词＋关系代词”引导定语从句。
如果指“人”，用“介词＋whom”；如果指“物”，用“介词＋which”。
例如：Do you know the lady with whom our manager is talking in the office?Where is the supermarket in which you bought the laptop last week?●使用“介词＋关系代词”要注意以下几点：(一)选用介词的依据：(1) 根据定语从句中谓语动词的搭配习惯(即固定短语)。
例如：Yesterday we visited the West Lake for which Hangzhou is famous.(2) 根据先行词的搭配习惯(约定俗成，不一定是短语)。
例如：The old woman with whom you talked just now is a famous artist.(3) 根据句子的意思来选择。
例如：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。
定语从句中介词+关系词
“介词+关系词”的用法1、关系代词在从句中作介词的宾语时，介词常可以提前,但介词提前时,关系代词只能用which 或whom.如:The school （that/which) he once studied in is very famous.→The school in which he once studied is very famous。
Tomorrow I will bring here a magazine （that/which）you asked for.→Tomorrow I will bring here a magazine for which you asked。
We’ll go to hear the famous singer (whom/that/who）we have often talked about。
→We’ll go to hear the famous singer about whom we have often talked.2、关系副词when, where, why 和介词+which之间的关系。
关系副词when, where，why可以用适当的介词+which来替代。
介词的位置非常灵活，有时放在关系代词之前，有时放在动词之后。
如：when=in/on/at…+which, where=in/on/at…+which， why=for+which 如:I won’t forget the date when( on which）I was born.This is the room where （in which) I lived. = This is the room which I lived in.I don’t know the reason why （for which) he hasn’t come today.Tom still remembers the days when （in which）they lived in Tianjin。

英语四六级语法：被分隔的定语从句
定语从句一般紧接被它所修饰的先行词；但有时候它和先行词之间有可能插入其他成分，使它与先行词分隔开来，这种定语从句叫作被分隔的定语从句，在阅读文章时会经常遇到这种情况，在阅读是要注意识别先行词的修饰对象。
一般说来，定语从句被分割开来大致有以下三种：
①在先行词与定语从句之间插入一个状语。
There are many thousands of stars in the sky that are like the sun.
在太空中有成千上万的象太阳般的星星。
乍一看，that引导的定语从句在名词sky的后面，似乎应该是修饰sky 的。
但仔细一想，不对啊，天空怎么能象太阳呢？原来that引导的定语从句被in the sky这个地点状语分隔开来，修饰中心词stars。
②在先行词与定语从句之间插入一个定语。
如：Do you remember one afternoon ten years ago when I came
to your house and borrowed a diamond necklace?
你还记得吗，十年前的一天下午，我来到你家，找你借了一条钻石项链？
when I came to your house and borrowed a diamond necklace 实际上是修饰afternoon而不是修饰years。
ten years ago 实际上是定语后置修饰afternoon。
③先行词与定语从句被谓语分隔开来。
此时，先行词通常是句子的主语，因定语从句较长，主句谓语较短，为使句子平衡，常将定语从句移至谓语之后
如：A new master will come tomorrow who will teach you
German.
明天，新（男）老师将来教你德语。
