如何確定定語從句的引導(dǎo)詞
引導(dǎo)定語從句的關(guān)系代詞有who, whom, whose, which, that;關(guān)系副詞有where, when, why。
它們都在定語從句中擔(dān)任句子成分。現(xiàn)分述如下:
1. 定語從句如果修飾人,常常用關(guān)系代詞who,有時(shí)也用that (作主語時(shí)多用who)。例如:
he is a man who / that often helps others. 他是一位經(jīng)常幫助別人的人。
如果這個(gè)關(guān)系代詞在從句中作賓語, 就應(yīng)當(dāng)用whom或that, 但這種情況往往都可以把引導(dǎo)詞省略,且在口語中可用who代替whom。例如:
here is the man (whom / that / who) you would like to see. 這就是你想見的那個(gè)人。
值得注意的是,如果是在介詞的后面就只能用whom。例如:
the boy to whom i spoke is my brother. 剛才和我說話的那個(gè)男孩是我弟弟。
如果表示“……的”時(shí),就用who的所有格whose。例如:
is there anyone in our class whose father is a doctor? 我們班有誰的父親是當(dāng)醫(yī)生的嗎?
whose的先行詞也可是物。例如:
the house whose windows face the street is my uncle's. 窗戶面朝街的那座房子是我叔叔的。
2. 定語從句如果修飾“物”,用關(guān)系代詞that的時(shí)候較多,有時(shí)也用which。例如:
it's a computer which / that costs six thousand yuan. 這是一臺價(jià)值六千元的電腦。
