1.(2011·安徽高考)The factory used 65 percent of the raw materials, the rest of which________ saved for other purposes.
A.is
B.are
C.was
D.were
解析:考查主谓一致。句意:这家工厂用了65%的原材料,剩余的被作为它用。raw materials 是先行词,which 引导的定语从句中,the rest 作主语;the rest 作主语时,谓语的数由其后的名词而定,而which=raw materials,所以谓语要用复数形式;由主句中的时态可知,从句中要用一般过去时态。故选D项。
答案:D
2.(2011·湖南高考)Onethird of the country________ covered with trees and the majority of the citizens ________ black people.
A.is; are
B.is; is
C.are; are
D.are; is
解析:考查主谓一致。“国家三分之一的领土”在概念上是单数,故系动词用单数;而“国家公民的大多数”是复数,故系动词用复数。句意:这个国家三分之一的领土被树木覆盖且多数公民为黑人。故选A项。
答案:A
