【题目】One-third 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
在线课程【答案】A
【解析】句意:这个国家三分之一的面积被树覆盖着,大多数居民是黑人。第一空填is,因为主语是分数修饰的时候,谓语由分数后面的名词决定,也就是country,所以用单数谓语,第二空填are,the majority of修饰主语,谓语也是由主语定,所以是和 the citizens一致,用are。答案是A。
