在as引導(dǎo)的非限制性定語(yǔ)從句中，連接代詞as在句子中可以作主語(yǔ)、賓語(yǔ)或表語(yǔ)等，可以指人或物。其在定語(yǔ)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(yǔ)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(yǔ)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。
