译林牛津版高三定语从句复习专题教案

1.which与as 一般可以用于非限制性定语从句中，代替整个主句，在从句中做成分。

which 一般位于句中，as 句中句首都可以，有“正如……一样”的含义，而which 却没有。

They have invited me to dinner, which is very kind of them.
2. 当先行词被so, such修饰时，关系词一般用as。

这里一定要注意与以下句型进行区分
so/such...as (定语从句，从句不完整，as在从句中做成分)
so/such...that （状语从句，从句完整，that 不做成分，只起到连接的作用）
He is such a lazy man as nobody wants to work with.
He is such a lazy man that nobody wants to work with him.
补充讲解：
(1)the same…that与the same…as引导的定语从句在意义上的区别：
①This is the same bag that I lost yesterday．这正是我昨天丢失的那个书包。

(同一个书包)
②This is the same bag as I lost yesterday．这个书包和我昨天丢失的那个一样。

(同类型的另一个)

关系代词which与as引导定语从句的区别
（1）which只能放在主句后面，而as引导的从句位置相对较灵活，可在前，可在后。

如：
（2）Which一般翻译成这一点，这件事，as一般翻译成“正如，就像”
As he realized，I was very useful to him.
（在前）正像他所意识到的那样，我对他非常有用。

Air，as we know, is a gas.（在中）空气，众所周知，是一种气体。

He was a foreigner, as I know from his accent.
(在后)他是个外国人，正像我从他的口音判断的那样。

He came late again, which made his boss angry.
（在后）他又来晚了，这一点使得老板很生气。

（3）在which引导的定语从句中，谓语动词若是am，is，are，则这些系动词不能省略，而as后面若是这种情况，则可以省略。

如：
He is a teacher，as (is)clear from his manner.(is可以省略)他是个老师，这从他的言谈举止可看清楚。

He said he had never seen her before，which was not true.
（was 不可省略）他说他从来没见过她，这一点不对。

例1：Whenever I met him, ____ was fairly often, I like his sweet and hopeful smile.
A. what
B.which
C.that
D.when
答案：B
解析：as和which都可以用来指代整个主句，在从句中充当主语、宾语和表语；两词通常可以互换。

但当位于句首时，只能用as。
