基数词和序数词的用法

作者: admin来源: 网络文章 时间: 2018-06-24

1. hundred, thousand, million 与数字连用,表示一定量的具体数字,不用复数,但表示不定概念可用复数

例:three hundred people, millions of people

2. 基数词表示时刻。

例:7点 seven o'clock, 7:20 seven twenty

3. 给某些事物编号

例:Lesson One=the first lesson

Bus No. 2 7月1日=July I (July Ist)

1996年6月3日=June 3, 1996=June the third, nineteen ninety-six

4. 有关分数表示法。分子是基数词,分母是序数词。当分子大于1时,分母就用复数。

例:I've read one-fifth of the books.

I've finished three-fifths of the words.

5. 有关倍数表示法

两倍用twice, 三倍以上用数词+times, 要注意倍数在句子的位置。

例:The door is three times the size of this.

6. 十位数字(个位为零)的基数词以复数形式出现时,表示年代、年龄

例:She is a good-looking woman in her forties. (forties 指40-49岁之间)
