1、限制性定语从句不能被省略，否则句意就不完整。非限制性定语从句与先行词关系不十分密切，只是对其作一些附加说明，不起限定制约作用。如果将非限制性定语从句省去，主句的意义仍然完整。二、外在表现形式不同限制性定语从句因与先行词关系密切，所以不可以用逗号将其与主句隔开；而非限制性定语从句与先行词关系不十分密切，所以可用逗号将其与主句隔开。例1. This is the place where he used to live.例 2. Mr. Zhang，who came to see me yesterday，is an old friend of mine.在例 1中，定语从句与先行词关系密切，为限制

2、性定语从句，不可用逗号将其与主句隔开。在例2中，定语从句与先行词关系不密切，为非限制性定语从句，可用逗号将其与主句隔开。三、先行词内容有所不同大多数限制性和非限制性定语从句的先行词往往为某一个词或短语，而特殊情况下非限制性定语从句的先行词也可为整个主句，此时非限制性定语从句常由 which 引导。例：1. A middle-aged woman killed her husband，which frightened me very much.由语境可知，令“我”恐惧的内容应为“中年女子杀害了自己的丈夫”这整个一件事，因此先行词为整个主句，此时应由 which 引导定语从句。2. A five-

3、year-old boy can speak two foreign languages， which surprises all the people present.由语境可知，令所有在场的人感到惊讶的内容是“一个五岁男孩会讲两门外语”这整个一件事，因此先行词为整个主句，此时应由 which 引导非限制性定语从句。四、关系词的使用情况有所不同（一） that 不可用于引导非限制性定语从句所有关系代词和关系副词均可引导限制性定语从句，大多数关系代词和关系副词可引导非限制性定语从句，但 that 不可。例如：他没通过这次考试，令我很失望。误：He didnt pass the exam，tha

4、t disappointed me.正：t pass the exam，which disappointed me.值得注意的是，不少同学误认为只有 which 才能引导非限制性定语从句，这个观点是不正确的。使用非限制性定语从句时，如果先行词指人，则用 who ， whom或 whose 引导非限制性定语从句；先行词指物可用 which 引导非限制性定语从句；先行词表时间或地点且在从句中作时间状语或地点状语时，可用 when，where 引导非限制性定语从句。例1. Well graduate in July，when we will be free.例2. Last Sunday they

5、reached Nanjing，where a conference was to be held.（二）关系代词替代情况不同关系代词 whom 在限制性定语从句中作宾语时可用 who 代替 whom ，但 whom 在非限制性定语从句中作宾语时不可用 who 来代替。例: 1. This is the girl whom I met in the street.先行词 the girl 在限制性定语从句中作宾语，可用 who 代替 whom . 2. A young man had a new girl friend，whom he wanted to impress.先行词 a new g

6、irl friend 在非限制性定语从句中作宾语，不可用 who 代替 whom .在限制性定语从句中，先行词指人时可用 that 代替 who/ whom ，但在非限制性定语从句中先行词指人时，不可用 that 代替 who/whom .她有一个姐姐，她是教师。 She has a sister，that is a teacher.She has a sister，who is teacher.（三）关系代词省略情况不同关系代词在限制性定语从句中作宾语时可以省去，非限制性定语从句的所有关系词均不可省。例 1. This is the book（which/that）he lost yeste

7、rday.先行词 the book 在限制性定语从句中作宾语，关系代词 which 或 that 可以省略。例 2. The book， which he lost yesterday， has been found.先行词 the book 在非限制性定语从句中作宾语，关系代词 which 不可省。（四）as引导定语从句时的用法 as引导限制性定语从句通常用于the same as, such as结构中。e.g. I want the same shirt as my friends. Such machines as are used in our workshop are made i

8、n China. 我们车间使用的这种机器是中国制造的。 as引导非限制性定语从句既可放在主句之前，也可放在主句之后，用来修饰整个句子。通常用下列句型：as is known to all, as is said, as is reported, as is announced, as we all know, as I expect 等。e.g. As I expected, he got the first place again in this mid-term examination. 3）as 引导非限制性定语从句时与which的区别 当主句和从句语义一致时，用as；反之，用which

9、来引导非限制性定语从句。e.g. He made a long speech, as we expected.He made a long speech, which was unexpected. 当非限制定语从句为否定时，常用which引导。e.g. Tom drinks a lot every day, which his wife doesnt like at all.2. 定语从句有时不直接紧靠先行词，中间由一个定语、状语或谓语隔开。这种定语从句叫做分隔性定语从句e.g. There is an expression in his eyes that I cant understan

10、d.4. 引导定语从句的关系副词有时可以用“介词 + which”来代替。e.g. October 1, 1949 was the day on which （ = when ） the Peoples Republic of China was founded.5. 当定语从句中谓语动词是带介词或副词的固定短语动词时，短语动词的各个固定部分不要拆开。e.g. The sick man whom she is looking after is her father.6. 介词在关系代词前，只能用which和whom，且不能省略；介词在句尾，关系代词可以省略。课外作业一、把下列每对句子合并成含有
