詞義辨析
that和which都可引導(dǎo)定語(yǔ)從句,但以下情況引導(dǎo)定語(yǔ)從句的關(guān)系代詞只能用that不能用which。
1、當(dāng)先行詞是all, everything, nothing, anything, little等不定代詞,或被first, last, only, few, much, some, any, no等詞修飾時(shí),應(yīng)該用關(guān)系代詞that,不用which。
2、當(dāng)先行詞為形容詞最高級(jí)所修飾時(shí),關(guān)系代詞用that不用which。
3、當(dāng)并列的兩個(gè)先行詞分別表示人和物時(shí),要用關(guān)系代詞that而不用which。
4、在強(qiáng)調(diào)句型“It is〔was〕...that〔who〕...”中,只能用that,不能用which。
