　　I 定語從句

　　1. 先行詞為all, anything, something, nothing, everything, much, little, none等不定代詞時(shí)，關(guān)系代詞一般只用that，不用which。在大多數(shù)情況下that可以省略.

　　Please tell me everything you know about the matter.

　　Thats all we can do at the moment.

　　2. as引出的限制性定語從句

　　在such as的結(jié)構(gòu)中as可作關(guān)系代詞，引出限制性定語從句。有時(shí)和same連用，在從句中可作主語、賓語或表語等。

　　Such people as were recommended by him were reliable.

　　Ive never seen such a talented young man as he is.

　　I have the same trouble as you .

　　3. as引出的非限制性定語從句

　　as可作關(guān)系代詞引出非限制性定語從句，代替整個(gè)主句，通常譯為如一樣，象一樣等。as引導(dǎo)的從句一般用逗號(hào)與主句隔開，可以位于主句的前面、中間或后面.

　　I live a long way from work, as you know.

　　She did not, as her friend had feared, break down.

　　As is generally accepted, economic growth is determined by the smooth development of production.

　　5.介詞+關(guān)系代詞引出的定語從句

　　如果關(guān)系代詞在定語從句中作介詞的賓語，那么這個(gè)介詞可以提到從句前，構(gòu)成介詞+關(guān)系代詞+定語從句。在這種結(jié)構(gòu)中關(guān)系代詞不可以用that。
