介词定语从句
定语从句介词知识点总结
定语从句介词知识点总结介词在定语从句中的使用分为两种情况：一种是介词前置，即介词位于定语从句中引导词的前面；另一种是介词后置，即介词位于定语从句中引导词的后面。
在具体的语境中，要根据不同的情况选择恰当的介词，并确保介词的使用符合语法规则。
一、介词前置情况1. 时间介词的前置在定语从句中，表示时间的介词如at, on, in等通常放在从句的先导词之前。
例如：The day when we met for the first time is still vivid in my memory.（我们第一次见面的那一天在我的记忆中依然清晰）I will never forget the moment when I held my baby for the first time.（我永远不会忘记我第一次抱着我的宝宝的那一刻）2. 原因介词的前置表示原因的介词如because of, due to等也通常放在定语从句中引导词的前面。
例如：The reason why she didn't come to the party is because of her illness.（她没来参加派对的原因是因为生病了）The failure of the project was due to the lack of funding.（这个项目的失败是因为资金不足）3. 地点介词的前置在表示地点的定语从句中，介词如in, at, on等也通常放在引导词的前面。
例如：The place where we met for the first time is now a bustling shopping mall.（我们第一次见面的地方现在成了一个繁华的购物中心）I will never forget the city where I spent my childhood.（我永远不会忘记我度过童年的那座城市）4. 其他介词的前置除了表示时间、原因、地点的介词外，其他表示方式、比较、程度等概念的介词也通常放在定语从句中引导词的前面。
定语从句中的介词可提前的全部情况
定语从句中的介词可提前的全部情况关系代词whom或which在定语从句中作介词宾语时,介词可放在后面,也可提前构成介词+关系代词whom (先行词指人)/which(先行词指物)引导定语从句(这种方法更为正式)。
例: Mary is the girl whom I borrowed a book from. = Mary is the girl from whom I borrowed a book. 玛丽就是我向她借书的那个女孩。
Is this the room that/which he once lived in? = Is this the room in which he once lived? 这是他曾经住过的房子吗?常见的有以下几种情况:1. where=in/on which 例:This is the room where / in which he lives.这是他住的房间。
I can see the playground where / on which they do sports.我能看见他们进行运动的操场。
2. when= on/in/at which 例:I still remember the year when/ in which I joined the Party.我仍然记得入党的那一年。
I still remember the day when/on which I joined the Party. 我仍然记得入党的那一天。
I still remember the hour when/at which the rocket was launched.我仍然记得那个火箭发射的时刻。
3. why=for which 例:This is the reason why / for which he was killed.这是他被杀害的原因。
但下列情况下介词不能提前:⑴用who代替whom,用that代替which时,介词不能提前。
介词提前的定语从句
介词提前的定语从句在英语语法中，定语从句是一种常用的句子结构，用于修饰名词或代词。
它通过引导词（关系代词或关系副词）与先行词之间的关系来提供进一步的信息。
在定语从句中，我们通常将引导词放在句子的末尾。
然而，在某些情况下，我们可以将介词提前到定语从句的引导词之前，以达到一种更加自然和流畅的表达方式。
介词提前的定语从句的常见情况是在关系代词之前加上介词。
这样做的好处是使句子更加简洁明了，并且可以避免使用复杂的介词短语结构。
例如：1.The book on which I'm reading is very interesting.→The book I'm reading is very interesting.（我正在读的那本书非常有趣。
）2.The girl with whom I went to the party is my best friend.→The girl I went to the party with is my best friend.（我和她一起去参加派对的那个女孩是我最好的朋友。
）3.The restaurant in which we had dinner last night was expensive.→The restaurant we had dinner in last night was expensive.（我们昨晚吃饭的那家餐厅很贵。
）通过将介词提前，我们可以使句子更加简洁，并且更符合日常口语的表达习惯。
这种结构在口语和书面语中都非常常见，而且能够帮助我们更好地理解句子的含义。
需要注意的是，不是所有的介词都可以提前到定语从句的引导词之前。
只有一些常见的介词，如with、in、on、for等可以进行提前。
而其他一些介词，如to、at、from等则不能进行提前。
因此，在使用介词提前的定语从句时，我们需要根据具体的语境和常用表达习惯来判断是否适用。

先行词是物，用which；若为人，就用whom。
如：(1) Nearby were two ships in which they had come to the island.(2) I can’t remember the name of the person to whom I gave the money.2、这一结构用介词取决于先行词的意义和定语从句中谓语动词结构及“介词+which/whom” 在句中的'作用。
(1) This is the room in which we lived last year.(2) There were three people from whom we attempted to find out information.3、因为含有介词的短语动词一般不拆开，介词仍放在动词的后面。

介词定语从句
介词定语从句
定语从句由关系词(关系代词、关系副词)引导，关系代词、关系副词位于定语从句句首。
下面是店铺为大家带来的介词定语从句!
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。
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.
(四)当先行词为way并且定语从句中缺少状语时，通常用in which或that引导定语从句(in which或that可省略);如果定语从句中不缺少状语，则用关系代词引导(that 或which 可省略)。
例如：All of us disliked the way(in which / that)Tom settled the maths problem.
I don’t understand the way(that/which)the teacher explained to me.
(五)in that不可以引导定语从句，但可以引导原因状语从句。
例如：
She didn’t atten d the meeting in that / because she was seriously ill.
二、“介词+关系代词”与关系副词的转化
(1)当先行词表示地点，定语从句中缺少地点状语时，通常用关系副词where引导，此时也可选用表示地点的介词+which来代替关系副词where。
例如：
I visited the village where many children couldn’t go to school because of poverty.
=I visited the villag e in which many children couldn’t go to school because of poverty.
(2) 当先行词表示时间，定语从句中缺少时间状语时，通常用关系
副词when引导，此时也可选用表示时间的介词+which来代替关系副词when。
例如：
We’d better fix a date when we will practice speaking English next week.
=We’d better fix a date on which we will practice speaking English next week.
(3) 当先行词为reason，定语从句中缺少表示原因状语时，通常用关系副词why引导，此时也可以用for which来代替关系副词why。
例如：
Can you tell me the reason why you were late for school?
=Can you tell me the reason for which you were late for school?
