1、Unit 5 In to the wild由关系副词引导的定语从句Part I 定语从句(2)由关系副词引导的1、定语从句的概念概念:在复合句中修饰名词或代词的句子叫作定语从句。定语：修饰，限定名词或代词的成分，翻译为“的”常见作定语的词：名词，代词，形容词，数词，介词短语等。eg.Mary is a beautiful gir.（形容词作定语）Mary is a girl with long hair.（介词短语做后置定语）Mary is a girl who has long hair.（句子作定语,修饰girl,叫做定语从句）2、定语从句的结构Mary is a girl who has

2、 long hair.先行词关系词定语从句关系代词关系副词hat,who,whom,whose,which where,when,why从句的谓语和先行词保持一致被从句修饰的名词或代词-关系词作用：引导定语从句，代替先行词在定语从句中充当主语，宾语，定语等成分，作宾语时常被省略。3、关系副词的用法引导定语从句的词，除关系代词外，还有关系副词when，where，why。(1)when表示时间，在定语从句中作时间状语，其先行词一般为表示时间的名词，time，day，week，year等eg.October 1st,1949 was the day when the Peoples Republi

3、c of China was founded.1949年10月1日是中华人民共和国成立的日子。3、关系副词的用法注意：有时尽管先行词是表示时间的名词，但如果定语从句中缺少的是主语或宾语，此时应使用关系代词。eg.I will never forget the days that/which I spent in the countryside.I will never forget the days when I worked in the countryside.3、关系副词的用法(2)where表示地点，在定语从句中作地点状语，其先行词一般为表示地点的名词，place，street，hou

4、se，city，country以及一些抽象名词，如point，case，position，condition，situation等eg.Everyone wants to visit the place where Zhou Enlai once worked.大家都想参观周恩来曾经工作过的地方。Is there a shop around where we can get fruit?附近有没有我们能买到水果的地方？3、关系副词的用法注意：where和when一样，在定语从句中只能充当状语；否则，必须换用关系代词。eg.This is the factory where my father

5、worked last year.This is the factory that/which my father visited last year.3、关系副词的用法(3)why表示原因，在定语从句中作原因状语，其先行词一般为reason。eg.The reason why she told a lie is unknown.她为什么撒谎还不清楚。We dont know the reason why they didnt attend the meeting.我们不知道他们为什么没有参加会议。比较：The reason that/which he gave us was hard to

6、accept.The reason why he was late for school is that he missed the first bus.4、归纳1）这三个关系副词在意义上都相当于“介词，which”的结构。when=（on/in/at/during）whichwhere=（in/at/on）whichwhy=for which2）当先行词是表示时间、地点、原因的名词，定语从句缺少主语or宾语，用which或that；定语从句缺少状语时，用when，where或why。Practice1.The days are gone _physical strength was all
