定语从句知识应该掌握到什么程度
Learning aims: 1. 关系副词where/when/why引导的定语从句 2. 介词+which/whom 引导的定语从句
1. 关系副词引导定语从句
在定语从句中，关系副词主要有3个：when, where和why.
1）when 在定语从句中表时间，作状语，其先行词往往是表示时间的名词，如：time, day, season, age, occasion 等。
I can’t forget the night when I came to the farm. 翻译：__________________________________________________
2)where在定语从句中表示地点，作状语，其先行词通常是place, city, town, factory, table, village, house等表示地点的名词 situation, case, condition, point等表示抽象意义的名词。
The factory where his father works is in the west of the city. 翻译：____________________________________________________
The country is in the situation where a war will break out at any time. 翻译：____________________________________________________ 3) why在定语从句中表示原因，作状语，先行词一般是reason.
That is the reason why I did so. 翻译：___________________________ I don’t know the reason why he didn’t come to school yesterday. 翻译：_____________________________________________________ 【注意】
1)并非先行词表示时间、地点或原因时,引导词就用when, where 或why;若定语从句中不缺状语而缺主语或宾语则须用which或 that引导定语从句。 I’ll never forget the days______ we worked together. I’ll never forget the days ______we spent together. Do you know the reason ______he failed in the exam this time The reason _____he gave me was reasonable.
2) when, where, why,引导的定语从句可用“介词+which”来替换。其介词可根据先行词和定语从句中的谓语动词来判断。
A. when相当于at/in/on/during等+which.
The date on which he joined the Party was July 1，1984. 翻译：
B. where相当于at/in/on/等+which
The house in which he lived is a library now. 翻译： C. why相当于for+which.
Is that the reason for which he was absent from class 翻译： 2. 介词+关系代词（which, whom）引导的定语从句
1) 介词+which 在定语从句中充当时间，地点，原因状语，相当于when, where, why.(上边已经讲述)
2) 介词+which/whom, 关系代词作介词的宾语，这是我们学习定语从句的重点，也是高考的常考点。which指物，whom指人。在这种结构中，介词的选择非常关键, 可根据定语从句所修饰的名词或代词来选择介词。也可根据从句的相关动词来选用。 This is the professor from whom I have learnt a lot. 翻译： Have you see the pen with which I write my homework. 翻译：
In the dark street, there wasn’t a single person to whom she could turn for help. 翻译：
【注意】在日常英语中通常把介词放在从句的句末，省略关系词which/whom This is the professor (whom/that) I have learned a lot from. This is the camera (which/that) he often takes photos with. 【学法点拨】
1）“介词+关系代词”引导定语从句时，介词的选取必须遵循“一先；二动；三意义”的原则。即：
a.根据先行词的搭配而定；
b.根据定语从句中谓语动词的搭配而定； c.根据整句话的意义而定。
2)介词+关系代词引导定语从句时，介词的选择应注意几个问题：
a.有的介词时定语从句中词组的固定搭配拆开的结果，用什么介词由从句的动词决定。
He is the boy who / whom I was talking to. =He is the boy to whom I was talking.
翻译：
b.有的介词是根据句意添加上去的，即用什么介词由先行词决定。
He employed 30 men, of whom 12 were from his hometown.
翻译： c.定语从句中的词组若是十分密切的固定搭配，一般不拆开。
The baby who/whom my sister takes care of is very lovely.
翻译：
【误区警示】：当定语从句的动词和介词是不可分割的固定搭配时，介词不能放到关系介词之前。 当堂检测
