of the land in my hometown 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 ; isD. Two fifths ; are解析：考查分数表达法与主谓一致：句意：我家乡三分之一的土地都是被树草覆盖着。英语分数表达法是分子用基数词，分母用序数词；分子大于 1 时分母用序数词的复数。分数做主语，谓语动词与分数后面of 所接的名词保持一致，the land 是单数，故答案为C。
