比較下面的考題：

1. This is the room _________I lived ten years ago.

A. that B. where C. who D. what

2. This is the room _________I lived in ten years ago.

A. that B. where C. who D. what

3. This is the room _________I bought ten years ago.

A. that B. where C. who D. what

4. This is the room _________I visited ten years ago.

A. that B. where C. who D. what

5. This is the room _________I was born ten years ago.

A. that B. where C. who D. what

第1題選B，因?yàn)?live 是不及物動(dòng)詞，它無(wú)需接賓語(yǔ);第2題選A，因?yàn)殡m然 live 不及物，但live in 卻是及物，它應(yīng)有自己的賓語(yǔ);第3、4題也應(yīng)選A，因?yàn)?buy 和 visit均為及物動(dòng)詞，它們應(yīng)有自己的賓語(yǔ);第5應(yīng)選B，因?yàn)?be born 無(wú)需有自己的賓語(yǔ)。

四、誤認(rèn)為逗號(hào)后一定是非限制性定語(yǔ)從句

有的同學(xué)一看見逗號(hào)，就以為一定要選which而不選that，但問(wèn)題是有時(shí)根本就不是定語(yǔ)從句。如：

1. If a book is in English, _________ means slow progress for you.

A. as B. which C. what D. that

2. When I say two hours, _________ includes time for eating.

A. as B. which C. what D. that

以上兩題均應(yīng)選that，而不能選which，因?yàn)樗鼈兏静皇嵌ㄕZ(yǔ)從句。之所以選that，是因?yàn)榫渲幸延衖f和when引導(dǎo)的狀語(yǔ)從句，逗號(hào)后為主句，that為主句主語(yǔ)。
