问题描述：

._____ of the land in that district _____
Covered with trees and grass.
A.Two fifth; is B.Two fifth; are
C.Two fifths; is D.Two fifths; are
为什么是C?

答

首先分词的用法：当分子大于1时候分母后面要加S
其次~后面的谓语动词依据主语具体而定你可以这样想如果是the land的话是 the land is Covered with trees and grass.现在才2/5那当然也是单数了

答

选C Two fifths; is
这里涉及到分数的表达方式,two fifths 指五分之二,two 是分子,用数词表示,fifths 是分母,用序数词表示,当分子大于一时,分母要用复数；
另外,由于主语是五分之二的土地,而它 1)不可数 2)不大于一,所以系动词用 is.
