高中定语从句讲义

　　定语从句内容大家掌握了吗？以下是小编精心准备的高中定语从句讲义，大家可以参考以下是内容哦！

　　一定语：修饰名词或代词的词、短语或从句称为定语。汉语中常用‘……的’表示。定语主要由形容词担任。此外名词、代词、数词、副词、介词短语以及动词不定式（短语）、分词也可以做定语。

　　a beautiful city; a bag full of money.注意：汉语的定语无论多长都放在被修饰词的前面，而英语中的定语则不然，是一个词时，放在被修饰词的前面，若是两个以上的词组、短语或从句则放在被修饰词的后面，

　　thirty women teachers ; his father; the girl in red. the boy from America

　　Our monitor is always the first student to enter the classroom.

　　falling leaves; fallen leaves; the boy playing basketball; the book bought by my mother; a reading room; a swimming pool

　　He is the man who you are looking for.

　　2．先行词：被定语从句修饰的名词或代词叫先行词。

　　3．关系词：引导定语从句的词叫关系词。关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等；关系副词有when, where, why.

　　（二）关系代词引导的定语从句

　　1．who 指人，在定语从句中作主语。

　　The boys who are playing football are from Class One. Those who want to go to the museum must be at the school gate at 7 tomorrow morning. Yesterday I helped an old man who had lost his way. That is the teacher who teaches us physics. 2．whom 指人，在定语从句中做宾语，常可省略。

　　注意：关系代词whom 在口语或非正式文体中常可用who 来代替，也可省略。

　　The man ( whom / who )you met just now is my old friend.

　　3．Which 指物，在定语从句中做主语或宾语，做宾语时常可省略。

　　Football is a game which is liked by most boys. He likes to read books which are written by foreign writers. The house which is by the lake looks nice. This is the pen ( which ) he bought yesterday. The film ( which ) they went to see last night was not interesting at all. 。

　　The classroom whose door is broken will soon be repaired.

　　The classroom the door of which is broken will soon be repaired.

　　Do you like the book whose cover is yellow?

　　Do you like the book the cover of which is yellow?

　　（一）限制性定语从句中只能用that 引导定语从句的情况

　　1．当先行词是everything, anything, nothing (something 除外), all, none, few, little, some等不定代词时，或当先行词受every, any, all, some, no, little, few, much等不定代词修饰时。如：

　　Have you taken down everything that Mr. Li said?

　　There seems to be nothing that is impossible to him in the world.

　　All that can be done has been done. 。

　　There is little that I can do for you.

　　He stayed in the library and looked up any information that they needed.

　　2．当先行词被序数词修饰时。如：

　　6．当先行词为人与物时。如：

　　（三）关系副词引导的定语从句

　　1． when 指时间，在定语从句中作时间状语。当先行词是表时间的名词，比如time, day, week, month, year等；且定语从句中缺时间状语时用when. 若先行词是表时间的名词，定语从句中缺主语或宾语时，用that/which引导。

　　I still remember the day when I first came to this school.

　　The time when we got together finally arrived.

　　Do you remember the years when he lived in the countryside with his grandpare？Do you remember the days（that/which） we spent together last year? I will never forget the days when we spent our holidays together. I will never forget the days that / which we spent together.

　　2． where 指地点，在定语从句中作地点状语。若先行词是表地点的名词，比如park, city, farm, place等；且定语从句中缺地点状语时用where. 若先行词是表地点的`名词，定语从句中缺主语或宾语时，用that/which引导。

　　3． why 指原因，在定语从句中作原因状语。若先行词是reason; 且定语从句中缺原因状语时，用why引导。若先行词是reason，定语从句中缺主语或宾语，用which/that引导。

　　Please tell me the reason why you missed the plane.

　　I don’t know the reason why he looks unhappy today.

　　I didn’t believe the reason (that/which) he explained to me

　　注意：关系副词引导的定语从句经常可以用“介词+关系代词”引导的定语从句来表示。如：

　　From the years when / in which he was going to primary school in the country he had known what he wanted to be when he grew up. Great changes are taking place in the city where / in which they live. The reason why / for which he refused the invitation is quite clear.

　　（四）“介词+关系代词which/whom”引导的定语从句

　　关系代词在定语从句中作介词宾语时，从句常常由“介词+关系代词”引出。

　　The school (which / that) he once studied in is very famous.

　　The school in which he once studied is very famous.

　　Tomorrow I’ll bring here the magazine (which / that) you asked for.

　　Tomorrow I’ll bring here the magazine for which you asked. This is the boy (whom / who / that) I played tennis with yesterday.

　　We’ll go to hear the famous singer about whom we have often talked. The manager whose company I work in pays much attention to improving our working conditions.

　　The manager in whose company I work pays much attention to improving our working conditions.

　　注意：１．含有介词的固定短语动词一般不拆开，介词仍放在短语动词的后面。如：look for, look after, take care of 等。

　　This is the watch (which / that) I am looking for. (正)

　　This is the watch for which I am looking . (误)

　　The babies (whom / who / that) the nurse is looking after are very healthy. (正)

　　The babies after whom the nurse is looking are very healthy. （误）

　　２．若介词放在关系代词前，关系代词指人时只可用whom，不可用who, that；关系代词指物时只可用which，不可用that。The man with whom you talked just now is my neighbour. (正) The man with that / who you talked just now is my neighbour. (误)

　　The plane in which we flew to Canada was really comfortable. (正) The plane in that we flew to Canada was really comfortable. (误)

　　３．“介词+关系代词”前还可有some, any, none, all, both, neither, many, most, each, few等代词或者数词。如：

　　He loves his parents deeply, both of whom are very kind to him.

　　In the basket there are quite many apples, some of which have gone bad.

　　There are forty students in our class in all, most of whom are from big cities.

　　Up to now, he has written ten stories, three of which are about country life. 注意事项:如何判断关系代词和关系副词

　　方法一：用关系代词，还是关系副词完全取决于从句中的谓语动词。不及物动词后面无宾语，就必须要求用关系副词或者是介词加关系代词；而及物动词后接宾语，则要求用关系代词。

　　例如：This is the mountain village where I stayed last year.

　　I'll never forget the days when I worked together with you.

　　判断改错（注：先显示题，再显示答案，横线；用不同的颜色表示出。）

　　（错） This is the mountain village where I visited last year.

　　（错） I will never forget the days when I spent in the countryside.

　　（对） This is the mountain village (which) I visited last year.

　　（对） I'll never forget the days (which) I spent in the countryside.

　　方法二：准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出关系代词/关系副词。例1. Is this museum ___ you visited a few days ago?

　　A. where B. that C. on which D. the one

　　例2. Is this the museum ____ the exhibition was held?

　　A. where B. that C. on which D. the one答案：

　　关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词 (who, whom, that, which, whose)；

　　先行词在从句中做状语时，应选择关系副词 ( where 地点状语，when 时间状语，why 原因状语) 。

　　（五）限制性定语从句和非限制性定语从句

　　限制性定语从句

　　形式上：不用逗号“，”与主句隔开。

　　意义上：是先行词不可缺少的定语，如删除，主句则失去意义或意思表达不完整。

　　译法上：译成先行词的定语：“．．．的”

　　关系词的使用上：A．作宾语时可省略 B．可用that C．可用who 代替whom

　　非限制性定语从句

　　形式上：用逗号“，”与主句隔开。

　　意义上：只是对先行词的补充说明，如删除，主句仍能表达完整的意思。

　　译法上：通常译成主句的并列句。

　　关系词的使用上：A．不可省略 B．不用that C．不可用who 代替whom

　　限制性定语从句举例：

　　The teacher told me that Tom was the only person that I could depend on. China is a country which has a long history.

　　In the street I saw a man who was from Africa.

　　His mother, who loves him very much, is strict with him.

　　China, which was founded in 1949, is becoming more and more powerful.

　　Last summer I visited the People’s Great Hall, in which many important meetings are held every year.

　　（二）关系代词as和which 引导的定语从句

　　as 和which 引导非限制性定语从句时，其用法有相同之处，也有不同之处。具体情况是：

　　1. as 和which都可以在定语从句中做主语或宾语，代表前面整个句子。如：

　　He married her, as / which was natural. 他跟她结婚了，这是很自然的事。

　　He is honest, as / which we can see. 他很诚实，这一点我们看得出来。

　　2. as 引导的非限制性定语从句可以放在主句之前、主句之后，甚至还可以分割主句。 which 引导的非限制性定语从句只可放在主句之后。另外，as 常常有“正如、正像”的含义。如：

　　As is known to all, China is a developing country.

　　He is from the south, as we can know from his accent.

　　John, as you know, is a famous writer.

　　Zhang Hua has been to Paris more than ten times, which I don’t believe.

　　注意：当主句和从句之间存在着逻辑上的因果关系时，关系词往往只用which。如：

　　Tom was late for school again and again, which made his teacher very angry.

　　These tables are made of metal, which made them very heavy.

　　1. 当先行词受such, so, the same 修饰时，关系词常用as。如：

　　I’ve never heard such stories as he tells.

　　He is not such a fool as he looks.

　　This is the same dictionary as I lost last week.

　　注意：当先行词受the same 修饰时，偶尔也用 that引导定语从句，但与as引导的定语从句意思有区别。如：

　　She wore the same dress that she wore at Mary’s wedding. She wore the same dress as her younger sister wore.

　　(三) 以the way为先行词时，若定语从句中缺方式状语，定语从句通常由in which或that引导，而且还可以省略。若定语从句中缺主语或宾语，用（that/which）引导定语从句。

　　The way (that / in which ) he answered the questions was surprising.

　　I don’t like the way (that / in which) you laugh at her. I don’t like the way (that/which) he told me.

　　做定语从句题一般分三步：第一找出先行词；第二看先行词在定语从句中的语能（做主语、宾语或状语）；第三选择合适的关联词。

　　A the smallest of which B the smaller of which

　　C the smallest of them D the smallest one
