of the land in that district(地区) covered with trees and grass.
A. Two fifth; is
B. Two fifth; are
C. Two fifths ; is
D. Two fifths; are

A. Two fifth; isB. Two fifth; are(答案→)C. Two fifths ; is D. Two fifths; are解析：考查分数百分数和主谓一致。在分数中，当分子大于一的时候，分母使用序数词的复数形式。故五分之二使用Two fifth。当分数做主语的时候，谓语动词的单复数根据后面的名称，如果名词是可数名词复数形式，谓语动词用复数，如果后面的名词是不可数名词，谓语动词用单数。本题后面是不可数名词land，故C正确。
