as引导定语从句的例子

  as引导定语从句的例子:

  ① 引导限定性定语从句时,指与先行词相似的人或物,必须用于 such/...或 the ...结构中,例如:

Such people as were mentioned by him were honest.

被他提到的这样的人是诚实的。

Last term our maths teacher set so difficult an examination problem as none of us worked out.

上学期我们数学老师出了一道我们没有一个人会的数学题。

This is the same bag as I lost yesterday.

这是和我昨天买的包一样的`包。

  ② 引导非限定性定语从句时,只能修饰句子,可置于被修饰句子后面、前面或主谓之间,翻译成“正如...那样”例如:

The earth moves around the sun, as we all know.

As we all know,The earth moves around the sun.

The earth, as we all know, moves around the sun

  ③ 在非限制性定语从句中,which和as引导定语从句时的区别:

a. which引导的从句不能放在主句前,而as引导的从句则既可以放在主句前,也可以放在主句后,还可以放在主谓之间。

b. as和which都可以指代一个句子,但as有“正如”、“就像”之意,which则没有此含义。

c. as 引导的非限定定语从句只能修饰句子,which 引导的非限定性定语从句可以修饰句子,也可以修饰名词。
