题目内容
3.The number of the students in our grade ___________about six _________,______ of them are girls.( )| A. | are; hundreds; two-thirds | B. | is; hundred; two-third | ||
| C. | is; hundred; two-thirds. |
分析 我们年级的学生的数量大约是六百,三分之二是女生.
解答 答案:C.the number of…表示…的数量,谓语动词用单数is,六百用six hundred,(数词+单位词的单数),序数词的表达方式是分子是基数词,分母是序数词,分子大于1,分母用序数词的复数,故答案是C.
点评 the number of表示"…的数量",跟复数名词连用作主语时,中心词是number,谓语动词要用单数.例如:
The number of students in our class is50.我们班学生的数量是50人.
The number of pages in this book is 60.这本书有60页.
2.a number of表示"许多",相当于 many,修饰可数名词复数.作主语时,谓语动词用复数.number前可用large,small等修饰,以表示程度.例如:
A number of students are planting trees on the hill.许多学生在小山上植树.
