关系副词引导的定语从句： 1、由where引导的定语从句。 定语从句在修饰一个表示地点的名词时,常用where引导。 A book office is a place where tickets are sold. Where 在从句中做状语，相当于一个介词短语。在本句中相当于in which，所以此句可以改为： A book office is a place in which tickets are sold. 因此定语从句中关系副词where= 介词 +which . This is the house where he lives. = This is the house ___________he lives. = This is the house _____________he lives in. 2、定语从句在修饰一个表示时间的名词时，常用when 引导。 I still remember the year we studied together. When在从句中时间状语，其作用相当于一个“介词+关系代词” I still remember the year we studied together. I still remember the year we studied in together. 3、由why引导的定语从句。 ①关系副词why 的先行词只有reason , 在从句中表示原因状语。 Do you know the reason why I left early Why 在从句中作原因状语，其作用相当于for which . Do you know the reason _____________I left early ②但如果关系词在从句中不是作状语，而是作宾语时仍用that/which . The reason ___________ he gave us was unacceptable. 关系代词和关系副词的选用。 在定语从句中到底选用关系代词还是关系副词要看它们在从句中所充当的句子成分来决定，有时同一个先行词往往关系词却不同。 1.This is the factory ____________ produces TV sets. This is the factory _________ my father once worked. (in which) 2.I’ll never forget the day __________ we spent together in the countryside. I’ll never forget the day _________ his house was broken into. (on which) 四、as引导的定语从句: ⑴ as用作关系代词和关系副词引导限制性定语从句，并在从句中做主语、表语和状语，构成the same… as, such … as等结构。 I want to have such a dictionary as he has. I shall do it in the same way as you did. I like the same book as you do. ⑵ as引导非限制性定语。在从句中做主语、表语或宾语，这个定语从句说明整个句子，可以放在主句之前、之中和之后。 The experiment is very important, as indeed it is. As is known to all, he studies very hard. As we all know, China is a developing country. 常用于这种类似插入语的句式有as is said above, as is already mentioned above, as is known to all, as it is, as is often the case, as is reported in the newspaper. 注意：which 和 as 的区别是： ①which不能放在句首，而as则可以； ②在句中时，as有“正如”、“就像”之意，而which 没有。 下列每句均有一处错误，请找出并改正。 1．They talked for half an hour of the things and persons who they would deal with a few days later． 2．Who is the man who was praised at the meeting？ 3．Is this the farm where you visited the other day？ 4．Is this factory which you visited last week？ 5．I want to buy the same dictionary that you have． which引导的非限制性定语从句。 I have lost my pen, which I like very much. She was awarded a gold medal, which the whole family considered a great honor. She is always late for class, which makes the teacher angry. 限制性定语从句与非限制性定语从句: 限制性定语从句非限制性定语从句和先行词关系密切（删去影响整个意思表达）和先行词关系不密切（一种补充说明，删去不影响全句意思的表达）不用逗号隔开一般用逗号隔开可用关系代词that不可用关系代词that关系代词可省略（但在从句中作宾语)关系代词不可以省略 只可修饰先行词，不可以修饰主句或主句的一部分除修饰先行词还可以修饰整个主句或主句的一部分暗示被修饰的先行词不是唯一的表示被修饰的先行词是唯一的翻译时先翻译从句在翻译主句翻译时先译主句再译从句
练习： I have a sister who is a doctor. 我有一个医生的姐姐。(姐姐不止一个) I have a sister, who is a doctor. 我有一个姐姐，她是当医生的。(只有一个姐姐) Peter drove too fast, which was dangerous. (which指 ) He changed his mind, which made me very angry. (which指 ) Mr. Smith, who is our boss, will leave for Japan next week. 。 (先行词为专有名词，要用非限制性定语从句修饰) Her father, who has a lot of money, wishes her to study abroad. (先行词为表独一无二意义的普通名词，要用非限制性定语从句修饰) 关系词的选用： 关系词先行词所指先行词所指 关系 代词that人/物主、宾、表which物主、宾who人主、宾whom人宾whose人/物定as人/物/事情主、宾、表关系 副词when时间时间状语where地点地点状语why原因原因状语
注意： 1 关系代词和关系副词在定语从句中都要充当句子成分。 2 当关系代词充当动词的宾语时可省略，当关系代词充当介词的宾语且介词不在关系代词之前的，关系代词也可省略。 3 定语从句中的谓语动词要和先行词保持一致。 4 定语从句分为限制性和非限制性两种。 5 非限制性定语从句中的关系词不可以省略。
