知识点-介词+which引导定语从句.pptx

在句子中作定语，修饰名词或代词的从句。这种从句由关系代词 或关系副词引导，并作句子成分。 定语从句还叫做嵌入句， 因形容词定语，所以又称之为形容词性从句。
定语从句的位置：通常在先行词（在主句中）后。

【二、as与which引导定语从句的用法辨析】
2). as表示“因为”、“由于”，引导原因状语从句，其语气 不如because强，通常为附加说明的理由，且是已知晓的原因， 主句与从句没有逻辑上的因果关系。
As she was not well, I went there alone. 因为她身体不好，所以我独自到那里去了。 As he is a tailor, he knows what to do with this material. 由于他是个裁缝，他知道怎样利用这块布料。

▲ as通常以the same … as或such … as的形式引导定语从句，as在定 语从句中作主语、宾语或表语等。 as和which引导非限制性定语从句中都能指代整句内容，which译为“这”， as 译为“正如”。但定语从句位于句首时只能用as。As we all know,…/As is known to all,…(正如大家所知道….)

三、非限制性定语从句
试卷讲评课件
非限定性定语从句，从句式上看，有逗号隔开。它既可以修饰先行词， 也可修饰整个句子。它对其先行词没有限定、修饰的作用，只起补充、 说明的作用。 1.非限制性定语从句通常不能用that 2. 非限制性定语从句不能用why引导，要用for which代替why。例如： I had told them the reason，for which I didn't attend the meeting. 3. 非限制性定语从句置于句首时，不能用which引导。关系代词as引导 非限制性定语从句位置比较灵活，可以放主句前，也可以放主句后。
