题目内容
7.______ of the sand in that district _______ covered with trees and grass.( )| A. | Two fifths,are | B. | Two fifth,are | C. | Two fifth,is | D. | Two fifths,is |
分析 那个地区五分之二的沙田被树木和草所覆盖.
解答 答案:D.
根据语境推测句意是"那个地区五分之二的沙田被树木和草所覆盖.",由此判断句中要使用分数五分之二,分数表达法是:分子用基数词,分母用序数词,如果分子大于1,分母要加-s,所以五分之二的正确表达为:two fifths.此题中分数修饰的名词sand是不可数名词,所以be动词用is,故选D
点评 本题考查分数表示法.首先知道:分子用基数词,分母用序数词;如果分子大于一,分母用序数词的复数形式.然后再根据题干选出正确的选项.
