關系代詞和關系副詞的區別

關系代詞在從句中作主語或賓語，關系副詞在句中作狀語。在句子中作定語修飾名詞或代詞的從句，這種從句有關系代詞或關系副詞引導并作句子成分，定語從句從句還叫做嵌入句，因形容詞定語，所以又稱之為形容詞性從句。定語從句的位置通常是在先行詞后。

關系代詞（that, who, whom, whose, which）所代替的先行詞是人或物的名詞或代詞，并在句中充當主語、賓語、定語等成分。

1.Is he the man who/that wants to see you?（who / that在從句中作主語，指人）

2.He is the man whom/ that I saw yesterday.（whom / that在從句中作賓語，指人）

3.They rushed over to help the man whose car had broken down.（whose在句中作定語，指人）

4.Please pass me the book whose (of which) cover is green.（whose在句中作定語，指物。若指物，它還可以同of which互換）

5.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carry的賓語，指物）

關系副詞（when, where, why, that）可代替的先行詞是時間、地點或理由的名詞，在從句中作狀語。關系副詞when, where, why的含義相當于"介詞+ which"結構，因此常常和"介詞+ which"結構交替使用。

6.Beijing is the place where (in which) I was born.

7.Is this the reason why (for which) he refused our offer?

8.His father died the year (that / when / in which) he was born.

9.He can’t find the place (that / where / in which) he lived forty years ago.
