as引导定语从句的例子
在复合句中,修饰名词或代词的从句叫定语从句。引导定语从句的词叫关系词。被修饰的名词或代词叫先行词。定语从句一般放在先行词的后面。下面为大家介绍关于as引导定语从句的例子,欢迎阅览!
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/so...as...或 the same...as...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。
