只能用that，不能用which的情況：

①先行詞既有人,又有物時。

②先行詞被序數(shù)詞或形容詞最高級修飾時,只用that。

③先行詞有theonly,thevery,thejust,theright等修飾時,只用that。

④不定代詞,如something,anything,nothing,everything,all,much,few,any,little,none等作先行詞時,只用that,不用which。

⑤當(dāng)主句是以who或which開頭的特殊疑問句時,用that以避免重復(fù)。

區(qū)分that和which

只用which而不用that的情況

①非限制性定語從句只用which而不能用that。

歸納3：

as和which在引導(dǎo)非限制性定語從句時可代替整個主句。

as和which引導(dǎo)非限制性定語從句時的位置不同:

as引導(dǎo)的定語從句可置于___________________，而which引導(dǎo)的非限制性定語從句不可放在_______________________________。

(3)as引導(dǎo)的定語從句有“__________的意思，而which指“_________”

句首、句中

句首，只能放在句中

關(guān)系詞as和which的區(qū)別

正如…….

這…….

as,which引導(dǎo)非限制性定語從句的區(qū)別

aswhich

指代引導(dǎo)的從句只能指代整個主句的內(nèi)容引導(dǎo)的從句既可指代整個主句的內(nèi)容，又可指代主句的某一名詞或代詞

位置可位于主句之前、之中或之后可位于主句之中或之后，

不能位于主句之前

意義“正如，就像…”“這，那”

功能起連接上下文的作用，表達(dá)說話人的觀點、看法，并指出主句內(nèi)容的根據(jù)或出處等引導(dǎo)的從句，在意義上相當(dāng)于一個并列句
