题目内容
13.Three fifths of the land in that district ______covered with trees and grass in the past.( )| A. | is | B. | are | C. | was | D. | were |
分析 在过去,那个地区有五分之三的陆地被树和草所覆盖.
解答 答案:C.
根据时间状语in the past结合语境推测句意是"在过去,那个地区有五分之三的陆地被树和草所覆盖."句子表述的是过去的事情,所以用一般过去时;再根据主语Three fifths of the land 是不可数名词(分数修饰名词时,由所修饰的名词决定单复数),所以 be动词用was.故选C
点评 关于主谓一致有很多种规则,比如就近原则等等,平时的学习中一定要掌握好规律,多多归纳总结,以防混淆.
