比较下面的考题:
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题选B,因为 live 是不及物动词,它无需接宾语;第2题选A,因为虽然 live 不及物,但live in 却是及物,它应有自己的宾语;第3、4题也应选A,因为 buy 和 visit均为及物动词,它们应有自己的宾语;第5应选B,因为 be born 无需有自己的宾语。
四、误认为逗号后一定是非限制性定语从句
有的同学一看见逗号,就以为一定要选which而不选that,但问题是有时根本就不是定语从句。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
以上两题均应选that,而不能选which,因为它们根本不是定语从句。之所以选that,是因为句中已有if和when引导的状语从句,逗号后为主句,that为主句主语。
