D.what答案：A（四）定語從句解題思路1.先看從句所缺句子成分：缺主、賓、表、定語，用關(guān)系代詞（that,which,who,whom,whose,as)；缺狀語，用關(guān)系副詞（when,where,why)；2.再看先行詞的指代：缺關(guān)系代詞時，看先行詞指人還是指物；缺關(guān)系副詞時，看先行詞指時間、地點還是原因。3.注意特殊情況：只用that或which，as引導(dǎo)的定語從句等。1判類型2看成分3看先行詞知識拓展1：先行詞為人，whose+n=the+n+of+whom/ofwhom+the+nThisisthescientist

Heboughtthesamebikeasyoudid.

Thereisnosuchbookasyoureferto.（2）單獨用作關(guān)系代詞，在引導(dǎo)非限制性定語從句時意為“正如”，可放在主句之前、之后或中間，且主從句之間一般要用逗號隔開。

eg:Allthebooksthatyouofferedhavebeengivenout.

eg:Theparkisthecleanestparksthatyoucanimagine.c.先行詞既指人又指物時。

eg:Tomstudieshardandisreadytohelpothers,whichhisparentsexpect.b.在由“介詞＋關(guān)系代詞”引導(dǎo)的定語從句中，指物只能用which。

從句的位置as引導(dǎo)的定語從句既可放在主句前，也可在主句后，which引導(dǎo)的定語從句只能放在主句后。表達(dá)意義as表示“正如”的意思（非限），常用搭配有：such＋n.＋as...和thesame＋n.＋as...（限）；which表示“這”的意思。2.as與which的區(qū)別知識點撥
