　　as引導(dǎo)的非限制性定語從句

　　在as引導(dǎo)的非限制性定語從句中，連接代詞as在句子中可以作主語、賓語或表語等，可以指人或物。其在定語從句中的位置比較靈活，即可以在句子前面，在句子中間或句子末尾。常用的結(jié)構(gòu)有：as we all know; as is well known to…; as is often the case; as is said/mentioned above; as has been said before; as I told you before; as is evident; as often happens; as can be seen; as is/was expected; as we expect; as I can remember等。

　　[注意1]as通常只指整個(gè)句子的內(nèi)容，不表示部分內(nèi)容。

　　[注意2]as引導(dǎo)的非限制性定語從句通常指“事先可以預(yù)料到的”“料想到的”，表達(dá)“好”的方面。

　　[注意3]as引導(dǎo)限制性定語從句時(shí)，常構(gòu)成the same…as…; such…as…; so/as …as…等結(jié)構(gòu)。在從句中既可以指人、物，也可以指整個(gè)句子。

　　[例句]

　　This is also part of your work， as I told you before. 我曾告訴過你，這也是你工作的一部分。

　　The man was a teacher， as was evident from his way of speaking. 從那人說話的樣子可明顯看出，他是個(gè)老師。

　　Such ideas as he hits on are worthless. 像他那樣偶然想起的主意是無用的。

　　It’s the same story as I heard from her yesterday. 這故事跟我從她那兒聽到的相同。

　　He will marry as pretty a girl as he can find. 他要盡可能找漂亮的女孩結(jié)婚。
