二．关系副词的基本用法指代关系副词在从句中的作用例句时间名词when（=at/ in/ on +which）时间状语I shall never forget the day when we moved into our new house. （先行词the day还原到从句中为: we moved into our new house on the day , 作时间状语，用when 或 on which）我永远不会忘记我们搬入新房子的那一天地点名词where（=at/ in/ on+ which）地点状语This is the village where my father was born. （先行词the village还原到从句中为: my father was born in the village, 作地点状语，用where 或in which）这就是我父亲出生的村庄原因名词why（=for which）原因状语This is the reason why he missed the early bus.（先行词the reason还原到从句中为: he missed the early bus for the reason, 作原因状语，用why 或for which）这是他错过早班车的原因。

三．关系副词和关系代词的正确使用关系副词和关系代词的选择要看先行词在定语从句中充当什么成分：如果作状语，则用关系副词；如果作主语、宾语、表语，则用关系代词，而不能只看先行词是什么I’ll never forget the day（that/ which）I spent with you on the farm. (先行词the day还原到从句中为: I spent the day with you on the farm, 作spent的宾语，用that/ which) 我永远不会忘记我们在农场一起度过的那一天I’ll never forget the day when I worked with you on the farm. (先行词the day还原到从句中为: I worked with you on the farm on the day, 作时间状语，用when或on which) 我永远不会忘记我们在农场一起工作的那一天He works in the factory（that/ which ）I visited last year. (先行词the factory还原到从句中为: I visited the factory last year, 作visited 的宾语，用that/ which) 他在我去年参观的那个工厂工作。

He works in the factory where these bikes are made. (先行词the factory还原到从句中为: these bikes are made in the factory, 作地点状语, 用where或in which) 他在制造这些自行车的那个工厂工作This is the reason (that/ which )he explained to us. (先行词the reason还原到从句中为: he explained the reason to us, 作explained的宾语，用that/ which) 这就是他对我们解释的理由I don’t know the reason why he was so angry.( 先行词the reason还原到从句中为: he was so angry for the reason, 作原因状语， 用why或for which)我不知道他如此生气的原因四．关系副词易错点：1.where指代抽象地点，意为“在…… 中（下）”where既可以指代具体的地点名词，也可指代抽象地点名词，常见的抽象地点名词：case, point, situation, condition, scene, stage, position，activity, platform, race, environment,atmosphere, family, job等。

I have reached a point in my life where I should make decisions of my own. 我已经到了一个在我人生中自己做决定的地步了Nowadays people are more concerned about the environment where they live. 目前人们更加关心他们所居住的环境Life is like a long race where we compete with others to go beyond ourselves. 人生像一场长跑比赛, 我们在比赛中和他人竞争以超越自己2.when指代抽象时间，意思为“在 ……的时间里”when既可以指代具体的时间名词，也可指代抽象时间名词，常见的有occasion（时机）, time, age, period等Occasions are quite rare when I have the time to spend a day with my kids.我有时间和孩子们呆一天的机会很少We are living in an age when many things are done on computers. 我们生活在一个许多事情靠计算机来做的时代。

3.why不能引导非限制性定语从句非限制性定语从句不能用why引导, 要用for whichI have told him the reason, for which I missed the early bus. 我没赶上早班车, 我已经告诉了他原因The main reason, for which he lost his job, was that he drank too much. 他失去工作的主要原因是酗酒4.way作先行词①先行词way在定语从句中充当方式状语，引导词用 that 或in which ，也可省略注意不用how, how不能引导定语从句②充当主语、宾语，引导词用 that 或which，做主语时不可省略，做宾语时可省略This is the way (that/in which) he solved the problem.(先行词the way还原到定语从句中为：he solved the problem in the way，作方式状语，引导词用 that 或in which，也可省略)这就是他解决问题的方法This is the way (that/which) he used to solve the problem.(the way作used的宾语，that/which可省略)这就是他所使用的解决问题的方法。

This is the way that/which was used to solve the problem.(the way作was used的主语，that/which不可省略)这就是被使用的解决问题的方法五．使用定语从句时注意的几个方面：（一）分割式定语从句定语从句和它所修饰的先行词中间插入谓语、状语或另外的定语等成分，使定语从句与所修饰的名词分割开来，或者插入语把引导词与定语从句分割理解句子时，注意找准先行词A newteacherwill come tomorrow whowill teach us English.教我们英语的一位新老师明天就要到了The days are gone when physical strength was what you needed to make a living.完全靠体力挣钱谋生的时代已经过去了I walked up to the top of the hill with my friend, where we enjoyed a splendid view of the lake. 我和朋友爬到了山顶，在那里我们欣赏了美丽的湖光景色。
