引導(dǎo)定語從句的關(guān)系詞分：關(guān)系代詞和關(guān)系副詞,用法如下：
關(guān)系代詞所代替的先行詞是人或物的名詞或代詞,并在句中充當(dāng)主語、賓語、定語等成分.關(guān)系代詞在定語從句中作主語時(shí),從句謂語動(dòng)詞的人稱和數(shù)要和先行詞保持一致.
1）who,whom,that
這些詞代替的先行詞是人的名詞或代詞,在從句中所起作用如下：
Is he the man who/that wants to see you?
他就是你想見的人嗎?（who/that在從句中作主語）
He is the man whom/ that I saw yesterday.
他就是我昨天見的那個(gè)人.（whom/that在從句中作賓語）
2) Whose 用來指人或物,(只用作定語,若指物,它還可以同of which互換),例如：
They rushed over to help the man whose car had broken down.那人車壞了,大家都跑過去幫忙.
Please pass me the book whose (of which) cover is green.請(qǐng)遞給我那本綠皮的書.
3)which,that
它們所代替的先行詞是事物的名詞或代詞,在從句中可作主語、賓語等,例如：
A prosperity which / that had never been seen before appears in the countryside.農(nóng)村出現(xiàn)了前所未有的繁榮.（which / that在句中作賓語）
The package (which / that) you are carrying is about to come unwrapped.你拿的包快散了.(which / that在句中作賓語)
關(guān)系副詞可代替的先行詞是時(shí)間、地點(diǎn)或理由的名詞,在從句中作狀語.
1）when,where,why
關(guān)系副詞when,where,why的含義相當(dāng)于"介詞+ which"結(jié)構(gòu),因此常常和"介詞+ which"
結(jié)構(gòu)交替使用,例如：
There are occasions when (on which) one must yield.任何人都有不得不屈服的時(shí)候.
Beijing is the place where (in which) I was born.北京是我的出生地.
Is this the reason why (for which) he refused our offer?這就是他拒絕我們幫助他的理由嗎?
2）that代替關(guān)系副詞
that可以用于表示時(shí)間、地點(diǎn)、方式、理由的名詞后取代when,where,why和"介詞+ which"引導(dǎo)的定語從句,在口語中that常被省略,例如：
His father died the year (that / when / in which) he was born.他父親在他出生那年逝世了.
He is unlikely to find the place (that / where / in which) he lived forty years ago.他不大可能找到他四十年前居住過的地方.
What只能引導(dǎo)名詞性從 句,用作連接代詞,作從句的具體成分,且不能省略.
I think (that) you will like the stamps.
What we need is more practice.
