题目内容
18.________ of the city was covered with the heavy smog.( )| A. | Two-third | B. | Two-thirds | C. | Two-three | D. | Two-threes |
分析 翻译:这个城市的三分之二被笼罩在浓雾之中.
解答 答案:B.根据"of the city"可知此空需要分数来表达覆盖着浓雾的区域.根据分数的构成:先分子,后分母,基数词表示分子,序数词表示分母.(three的序数词为third).如果分子大于1,分母要用复数形式.two-thirds为三分之二.故选B.
点评 本题考查英语分数表达法,分子读作基数词,分母读作序数词.如果分子是1,则分母直接读作序数词;如果分子大于1,则序数词要加s.
