定语从句介词用法
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 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。
定语从句引导词的用法
定语从句引导词的用法
一、that的用法
1 、在定语从句中，that 引导的定语从句，在句中作宾语或状语。
① 作宾语：
We discussed something about the plan 〔that〕we thought was realistic.
我们讨论了一些我们认为现实可行的关于计划的事情。
他工作很努力，几乎未能把所有工作做完。
2、在含有介词的定语从句中，that 几乎不用，介词后面直接接定语从句。
这就是她从哪里获得资金的原因。
他找到了他要找的钥匙。
这就是她曾经工作的那栋建筑物。
三、whose的用法
1、whose 引导定语从句，其意思是“…的”，它只能指人，一般在句中作定语。
头发乱糟糟的女孩走进了房间。
2、whose 也可以替代 of which 来引导定语从句，但只能用于某些句型中。
He is the teacher 〔whose〕books I read.
他就是我读过书的老师。
定语从句介词加关系代词用法
定语从句介词加关系代词用法在定语从句中，介词加关系代词的用法如下：1.关系代词在介词前：当关系代词作为定语从句的主语时，介词通常放在关系代词的前面。
例如：- The man whom I spoke to is my boss.（我与之交谈的那个人是我的老板。
）- The book that I am looking for is on the table.（我要找的那本书在桌子上。
）2.关系代词在介词后：当关系代词作为定语从句的宾语时，介词通常放在关系代词的后面。
例如：- The house which he lives in is very old.（他住在的那栋房子很旧。
）- The car that she is interested in is not available.（她感兴趣的那辆车不可用。
）需要注意的是，当介词后的关系代词是which时，可以省略介词。
例如：- The city which I was born in is famous for its architecture.（我出生的那座城市以其建筑而闻名。
）- The city I was born in is famous for its architecture.（我出生的那座城市以其建筑而闻名。
）同时，也可以通过适当拓展定语从句来提供更多信息：- The man whom I spoke to yesterday, in the cafe near my office, is my boss.（昨天我在我办公室附近的咖啡馆里与之交谈的那个人是我的老板。
）- The book that I am looking for, which is a bestseller,is on the table.（我正在找的那本畅销书就在桌子上。
）。
定语从句介词提前用法
定语从句介词提前用法定语从句是英语中非常重要的一种语法结构，它可以用来修饰名词或代词，进一步描述或限定其所指的对象。
而介词提前则是定语从句中常用的一种表达方式，它可以使句子更加简洁明了，也更符合英语语言的表达习惯。
介词提前的用法可以通过以下例句来理解：1. The book on the table, which I borrowed from the library, is very interesting.这句话中，介词on被提前到定语从句的开头，修饰名词table。
定语从句的主语是I，谓语是borrowed，关系代词which指代的是book。
2. The girl in the red dress, whom I met yesterday, is my new neighbor.这句话中，介词in被提前到定语从句的开头，修饰名词dress。
定语从句的主语是I，谓语是met，关系代词whom指代的是girl。
3. The man with the beard, whose car was stolen, reported thetheft to the police.这句话中，介词with被提前到定语从句的开头，修饰名词beard。
定语从句的主语是car，谓语是was stolen，关系代词whose指代的是man。
通过以上例句可以看出，介词提前的用法可以使定语从句更加简洁明了，同时也可以使句子的语气更加自然流畅。
在实际应用中，我们可以根据需要灵活运用介词提前的用法，使句子更加优美。
除了介词提前，定语从句还有其他的表达方式，比如关系代词的省略、关系代词的替换等。
在使用定语从句时，我们需要注意以下几点：1. 关系代词的选择：在定语从句中，关系代词的选择要根据其在从句中所扮演的角色来确定。
比如，主语要用who或that，宾语要用whom或that，所有格要用whose等。
2. 关系代词的位置：在定语从句中，关系代词的位置要放在从句中所修饰的名词或代词之后，这样才能清晰地表达出其所指代的对象。

定语从句中介词加关系代词的用法
定语从句中介词加关系代词的用法定语从句是指用来修饰名词或代词的从句，在英语语法中有丰富多样的用法。
其中，当介词与关系代词相结合时，就构成了定语从句中介词加关系代词的用法。
在这种结构中，介词在定语从句中起到特定的作用，而关系代词则在从句中充当连接词。
常用的关系代词有：who, whom, whose, which, that。
介词在定语从句中主要有以下几种情况的用法。
1. 介词+关系代词在从句中作宾语时，介词可以放在关系代词之前或之后。
例如：- The book which I am looking for is on the table.- The book for which I am looking is on the table.2. 介词+关系代词在从句中作宾语时，如果介词是短语动词的一部分，介词只能放在关系代词之后。
例如：- That is the man whom I am talking about.- That is the man about whom I am talking.3. 介词+关系代词在从句中作定语时，关系代词的选择要根据介词的要求而定。
例如：- The book on which I am working is very challenging.- The house in which she lives is beautiful.4. 当关系代词是物格形式（whom），介词可以前置到关系代词之前。
例如：- The person to whom I gave the book is my friend.- The person whom I gave the book to is my friend.需要注意的是，在口语中，人们往往更倾向于使用介词后置的形式，即将介词放在关系代词后面。
同时，有时候可以使用介词+which来替代介词+关系代词的结构，这种形式更加简洁。

(三)数词(不定量数词)/ 含所属关系名词+of whom/which引导定语从句。
例:She has many books, only one of which is interesting. 她有许多书,只有一本是有趣的本单元的语法重点是区别和运用几个表示原因的连词和词组：because, since, as, due to, due to the fact that等。
一、连词的主要用法。
连词是一种在句子之间，短语之间以及名词等其他词语之间起连接作用的虚词，它不能单独作句子的成分。
连词按其意义可分为并列连词和从属连词两大类，对连词的考查主要也是对并列连词和从属连词基本用法的考查。
本单元主要练习使用用来表示双方互为因果，前因后果或前果后因的连词，亦可用这种连词引导原因状语从句，常用的连接词有：because, since, as等。
二、 because, because of, since, as, for, due to, due to the fact that的联系与区别。
1. 联系：以上的词和词组都表示原因，意为“因为；由于”。
2. 区别(1) because通常表示说话人认为这种理由或者原因是听话人所不知道的，后接从句，既可以位于句首也可以放在句中使用，但不与so连用。
如： He didn't attend the meeting because he had too much work to do.(2) because of 与because所表达的意思一样，但其后接单词或短语。
如：He didn't go to school because of illness.(3) since表示的原因是人们已知的事实，常译作“既然”。
如：Since he can't answer this question, you'd better ask someone else.(4) as表示原因与since差别不大，只是语气更弱,多译作“由于”。
如：As I haven't seen the film, I can't tell you what I think of it.(5) for表示因果关系时，只能放在主句之后，不能放在句首。
而且经常是对主句补充说明理由或推断原因。
如：It rained last night, for the ground is wet.⑹ due to是说明原因的短语，to 为介词，因此due to 后接名词或名词性短语。
如：Due to the benefits of garlic, he decided to eat it more often.(7) due to the fact that 与due to意思相同样，但due to the fact that后接从句。
如： We stayed inside the house due to the fact that the weather was cold.单项选择。
