1.Is this museum ___ you visited a few days age?
A.where B.that C.on which D.the one
2.Is this the museum ____ the exhibition was held.
A.where B.that C.on which D.the one
答案：1 D,2 A
1变为肯定句：This museum is ___ you visited a few days ago.
2变为肯定句：This is the museum ___ the exhibition was held.
在句1中,所缺部分为宾语,而where,that,on which都不能起到宾语的作用,只有the one既做了主句的表语,又可做从句的宾语,可以省略关系代词,所以应选D.
而句2中,主、谓、宾俱全,从句部分为句子的状语表地点,既可用副词where,又因 in the museum词组,可用介词in + which 引导地点状语.而此题中,介词on 用的不对,所以选A.3.It rained hard yesterday,____ prevented me from going to the park..
A.that B.which C.as D.it
答案B.which可代替句子,用于非限定性定语从句.That 不能用于非限定性定语从句,it不为连词,使由逗号连接的两个句子并在一起在英语语法上行不通.4.I have many friends,________ some are businessmen.
A.of them B.from which C.who of D.of whom
答案D.考查介词＋关系代词引导的非限制性定语从句.介词后指人的关系代词只能用宾格whom,不能用who替代.
5.He reached London in 1996,_________,some time later,he became an actor.
