题目内容
20.There are many students in our school. of them girls.( )| A. | One third; is | B. | One third; are | C. | Two thirds; is |
分析 我们学校有许多学生,其中1/3是女生.
解答 正确答案:B.
分数的表达是:分子是基数词,分母是序数词,当分子大于1,分母要用复数形式,故1/3是one third,2/3是two thirds.其次分数+of作主语,其谓语根据of后面名词的单复数决定,句中them指代students,是复数形式,所以此处填写are,故选择B.
点评 本题考查分数,掌握分数常用的表达,及分数+of作主语时谓语的单复数.
