1、二、 定 语 从 句（一） 知识概要 定语从句并不属于中考范围，但由于作者在多年的教学中体会到，这一语法现象影响了许多学生自学英语。这些学生一般是成绩较好的学生，想进行大量阅读来提高自己的英语水平，但总是碰到一些问题，百思不得其解。苦于自己的水平只限于初中水平，无法提高，但各种补习班又都是为一些水平较差的学生开设的，所以又投师无门。为了解决这部分学生的学习困难，也为那些有志青年铺平学习上的道路，特用这一节讲述定语从句，不是从语法上讲述，而是从阅读理解方面去讲述。可供同学们在学习时参考。这会对你的英语学习起到事半功倍的作用。对于形容词我们已十分熟悉了，如： a good book， 形容词 go
2、od 用来修饰书 book。 我们也可以用一个句子来修饰名词，这种句子叫做形容词性从句，它起修饰名词的作用，又被叫做定语从句(The attributive clause)。但有一点不同的是这个从句不是像形容词那样放于名词前，而是放在名词之后。它所修饰的名词又被叫作先行词，如： Do you know the scientist who gave us the talk this afternoon? 这句中的主句是 Do you know the scientist? (你知道那位科学家吗?)而 who gave us the talk this afternoon (他今天下午给我们作的报
3、告。)是定语从句。所以这两句话合为一体即是：你认识今天下午给我们作报告的那位科学家吗?这里 scientist 叫作先行词，而 who 叫作定语从句的引导词。 who 在定语从句中起主语的作用， who 的数与它的先行词相同。又如： You must do everything that I do 这里先行词是 everything， 而 that I do 是定语从句，此句应译为：你必须作我所作的一切。 that 叫作定语从句的引导词，在句中作 do 的宾语。引导定语从句的引导词有关系代词： that， which， who， whom， whose 和关系副词 when， where， w
4、hy， how。不论关系代词还是关系副词，都应放于先行词和定语从句之间，起联系作用，但它们都要在定语从句中起语法作用，充当一个成份。如关系代词在定语从句中不是作主语便是作宾语，而关系副词则是作状语。我们先来看关系代词的用法。that 的先行词可以是人也可以是物。如： A plane is a machine that can fly 这里先行词是 machine 而 that 是关系代词，在定语从句中作主语。这句译为：飞机是一种会飞的机器。又如： I like the book (that) you lent me yesterday 这里先行词是 book， 关系代词用 that， 它在定语
5、从句中作 lend (借)的宾语。要注意的是关系代词在定语从句中作宾语时可以省略，即： I like the book you lent me yesterdaywhich 关系代词的先行词只能是物。它在定语从句中作主语或宾语，如： The book shop is a shop which sells books 这里 shop 是先行词， which 在从句中作主语。又如： The book (which) I read last night was wonderful 这里主句是 The book was wonderful 而定语从句是修饰主句的主语 book， 即我昨晚读的那本书，w
6、hich 在定语从句中作 read 的宾语，可以省略。who， whom， whose who 在定语从句中作主语， whom 是 who 的宾格，在定语从句中作宾语，而 whose 则是形容词性物主代词，在从句中作定语，如：The man who visited our school yesterday is an American friend 昨天参观我们学校的人是一位美国朋友。 Who 在定语从句中作主语。又如： Whos that woman (whom) you just talked to ? 你刚才与之谈话的那个女人是谁?而 whom 作定语从句中介词 to 的宾语，可以省略，
7、而在现代英语中，句首的 whom 也常常可用 who代替。This is our classmate， Mary， whose home is not far from our school 这是我们的同学玛丽，她的家离我们学校不远。为了便于理解，我们来看看是如何将两句话并为一句话的。 I saw the man. He closed the doorI saw the man who (that) closed the door2 The girl is happy She won the raceThe girl who won the race is happy3 The student
8、s are from China They sit in the front rowThe students who sit in the front row are from China(要注意的是先行词是 students 则 who 的数也应看作复数。)4 We are studying sentences They contain adjective dauseWe are studying sentences that (which) contain adjective dause 5 The taxi driver was friendly He took me to the ai
9、rportThe taxi driver who took me to the airport was friendly 6 The book was good I read itThe book that I read was goodThe book I read was good 7 The people were very nice We visited them yesterdayThe people we visited yesterday were very nice8 The man called the police His wallet was stolenThe man
10、whose wallet was stolen called the police9 I come from a country Its history goes back thousands of yearsI come from a country whose history goes back thousands of years10 I have to call the man I picked up his umbrella after the meetingI have to call the man whose umbrella I picked up after the mee
11、ting关系代词 whom， which 在定语从句中作介词宾语时，可以和介词一起放于先行词与定语从句之间，有时为了关系紧凑也可以将 whom 与 which 与先行词紧挨着书写，而将介词置于定语从句的后面，如：That was the room in which we had lived for ten years 或可以写作：That was the room which we had lived in for ten yearsHe was the man whom(who) you were looking for 要注意的是此句的关系代词 whom 可以用主格取代，而 look fo
12、r 是短语动词也不可将 for 放于定语从句之前。that 作关系代词作介词宾语时，不能紧跟介词，而只能将介词置于定语从句的后面。如： The man that we were talking about has come to our school 这时不可用 about that 请看下面例句：1 The meeting was interesting I went to itThe meeting that I went to was interesting 2 The man was very kind I talked to him yesterdayThe man who I ta
13、lked to yesterday was very kind3 I must thank the people I got a present from himI must thank the people who I got a present from4 The picture was beautiful She was looking at itThe picture that (which) she was looking at was beautiful5 The man is standing over there I told you about himThe man who
14、I told you about is standing over there除关系代词外，还有关系副词， when， where， why， 其中 when用来指时间，在定语从句中作时间状语。如： I never forget the day when I first came to the Great Wall 而 where 则指地点，如： This is the house where the old man lives 请看下面例句：1 The city was beautiful We spent our vacation thereThe city where we spent
15、our vacation was beautiful2 That is the restaurant I will meet you thereThat is the restaurant where I will meet you3 The town is small I grew up thereThe town where I grew up is small4 That is the drawer I keep my newpapers thereThat is the drawer where I keep my newspapers5 Monday is the day We will come thenMonday is the day When we will came6 is the time My plane arrives then is the time when my plane arrives7 is the year The revolution took place then is the year when t
