非限制性定語(yǔ)從句在句中主要起補(bǔ)充說(shuō)明作用，在非限定性定語(yǔ)從句與主句之間往往有逗號(hào)隔開(kāi)，獨(dú)立存在，確實(shí)也不會(huì)影響整個(gè)句子的意思。小編這次就為大家?guī)?lái)非限制性定語(yǔ)從句的講解，一起來(lái)看看吧。

1. as引導(dǎo)的非限制性定語(yǔ)從句

as有時(shí)作關(guān)系代詞，代替整個(gè)主句，對(duì)其進(jìn)行說(shuō)明

但as也回用于固定搭配，像as we all know, as it is known, as is known to all, as it is, as is said above, as always mentioned above, as is usual, as is often the case, as is reported in the newspaper等。

as在非限定性定語(yǔ)從句中作主語(yǔ)、表語(yǔ)或賓語(yǔ)，且引出的從句位置比較靈活，可位于句首或句末，也可置于主句中間。

eg. As we all know, Jack London is a famous American writer.

① which指代主句中的名詞。

eg.These apple，which were bought by my father，are very sweet.

② which指代主句中的形容詞。

eg.She was very patient towards the children，which her husband seldom was.

③ which指代主句中的某個(gè)從句。

eg.He said that he will love her forever，which was not true.
