疑問代詞who的用法

　　1.who在句中作主語：

　　Who's there?

　　who作主語通常視為單數(shù)，謂語動(dòng)詞要用單數(shù)。

　　改錯(cuò)題： Who are not at school today?改為is

　　其他主語例句： Who came when I was out?

　　Who put the light out before I finished my work?

　　2. who在句中作賓語：

　　Who have you chosen to take part in the sports meet?

　　你選了誰參加運(yùn)動(dòng)會(huì)？

　　此句重點(diǎn)是：主語是you，謂語動(dòng)詞用have，不能把who當(dāng)主語，謂語用has就錯(cuò)了。

　　其他例句：

　　Who did she lend the bike to?

　　Who did you see then?

　　3.who在句中作表語：

　　Who is she?

　　Who are this girl and this boy?

　　this girl and this boy是兩個(gè)人并列作主語，謂語動(dòng)詞用復(fù)數(shù)。

　　who用作疑問代詞時(shí)，意思是“誰”，一般只用來指人,在句中用作賓語或主語。

　　I wonder who that letter was from.

　　我不知道是誰來的信。

　　who用作限制性或非限制性的關(guān)系代詞，意思是“…的人，那個(gè)…”“他，她，他們”,在句中作主語。如：

　　The people (who) we met in France have sent us a card.

　　我們在法國結(jié)識(shí)的人給我們寄來了一張賀卡。
