不定代詞的用法

　　關(guān)系代詞who,whom,whose,that,which的用法

　　(1) 關(guān)系代詞who,whom,whose,that,which的用法

　　英語中的關(guān)系代詞有who,whom,whose,that,which,它們是用來引導(dǎo)定語從句的.關(guān)系代詞既代表定語從句所修飾的詞,又在其所引導(dǎo)的從句中承擔(dān)一個成分,如主語、賓語、表語或定語.如：

　　A child whose parents are dead is an orphan.

　　失去父母的孩子是孤兒.(whose在從句中作定語,它的先行詞是child)

　　He wants a room whose window looks out over the sea.

　　他想要個窗戶面臨大海的房間.(whose在從句中作定語,它的先行詞是room)

　　This is the man who saved your son.

　　這就是救了你兒子的那個人.(who在從句中作主語,先行詞是man)

　　The man whom I met yesterday is Jim.

　　我昨天見到的那個人是吉姆.(whom在從句中作賓語,它的先行詞是man)

　　[1] who,whom和whose

　　who和whom代表人,在從句中作主語時用who,作賓語時用whom,可省略.但若whom作介詞賓語且介詞放在其前時,不能省略;如介詞位于句末時,可以省略.whose代表某人的,在從句中作定語.如：

　　The man who insists upon seeing with perfect clearness before he decides,never decides.

　　堅持看清楚一切后才做決定的人永遠也做不了決定.(who作主語)

　　He is a man whom everybody respects.

　　他是一個人人都尊敬的人.(whom作賓語,可以省略)

　　He is a man fromwhom we all should learn.

　　他是我們大家都應(yīng)該學(xué)習(xí)的人.(whom作介詞賓語且介詞位于其前,不能省略)

　　(此句也可以是：He is a man (whom) we should all learn from.)

　　The people whose houses were damaged will be compensated.

　　房子被損壞了的人將給予補償.

　　Who,whom和whose可用于非限制性定語從句中,代表某人或某人的,此時不能用that.如：

　　我買的這張書桌是用橡木做的,它是二手貨.

　　[3] that

　　that可以代表事也可代表人,在從句中可以作主語或賓語,作賓語時可省略,但不能用于非限制性定語從句中.代表人時who比that用的多些,代表物時that比which用的多些.如：

　　(3) 沒有先行詞的關(guān)系代詞

　　如果關(guān)系代詞引導(dǎo)的從句不是作定語修飾先行詞而是充當(dāng)句子成分,這種關(guān)系代詞就沒有先行詞,它只起連接作用.這種關(guān)系代詞有：what,whatever,whoever,whichever,wherever等.如：

　　What woke me up was a splashing noise.

　　把我吵醒的是一陣濺水的聲音.(what從句作主語)

　　I don't know what good they could have done.

　　我不知道他們能起什么好作用.(what從句作賓語)
