高一英语必修一第四单元语法

必修一Unit4 语法定语从句定语可以由形容词、名词、代词、数词、分词(现在分词或过去分词)、副词、不定式(短语)以及介词短语等来充当,也可以由一个句子来充当。

充当定语功能的句子称为定语从句。

定语从句所修饰的名词或代词叫作先行词。

定语从句一般用关系代词或关系副词来引导,关系词放在先行词与定语从句之间起连接作用,同时在从句中充当某种成分。

1.关系词引导定语从句的关系代词和关系副词具体见下表:2.关系代词的用法关系代词指代先行词,在定语从句中作主语、宾语、表语、定语。

在从句中作宾语时,关系代词常可省略。

(1)that的用法that 指人或物,在从句中作主语、宾语或者表语,但that不用于引导非限制性定语从句。

( that/who在从句中作主语,不能省略)John is no longer the person ( that/who/whom) I knew five years ago.约翰不再是我五年前认识的那个约翰了。

译林版必修第一册Unit4单元语法--关系副词引导的限制性定语从句语法精析当先行词在定语从句中作状语时，通常要用关系副词引导定语从句。

常用的关系副词有where，when，why等。

1．关系副词wherewhere引导的定语从句的先行词往往是表示地点的名词(如place，room，house，spot等)，关系副词在从句中作地点状语。

常用in which，at which，on which等代替。

They are playing in the park where(＝in which) there are some flowers.他们正在有花的公园里玩耍。

The office where(＝at which) the girl works is not far from here.这个女孩工作的办公室离这儿不远。

[温馨提示]①有一些先行词，如point，stage，position，case，condition等，属于抽象的地点名词，如果定语从句中缺状语，需要接where引导的定语从句。

You reach a point in your project where you just want to get the thing f inished.从事任何项目你都会进入一种境界：一心想完成它。

We reached a stage where we had to answer violence with violence.我们陷入了必须用暴力来对抗暴力的境地。

②where引导定语从句和状语从句的区别：引导定语从句时，where是关系副词，在从句中作地点状语，其前有表示地点的名词作先行词，从句修饰先行词；引导状语从句时，where是从属连词，从句修饰主句的谓语动词，where前面没有表示地点的名词。

He’s got into a situation where he is likely to lose control over the plane.(定语从句)他陷入了一种很可能会失去对飞机的控制的境地。
