Explore and apply the rules wisely. 重 点 难 点 How to understand some difficult sentences. 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,
