關(guān)系副詞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。
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可以用于表示時間、地點、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。
