【知识梳理3】数词的用法

一、基数词的用法

1. 时间的表达

12小时制时刻的读法分为顺读法和倒读法。顺读法是依次读“点钟数、分钟数”。倒读法中，在前半小时：“分钟数＋past＋已过点钟数”；在后半小时：“分钟数＋to＋下个钟点数”。半小时用“half”，一刻钟用quarter

6: 00读作：six(o'clock)

7: 30顺读：seven thirty       倒读：half past seven

9: 15顺读：nine fifteen       倒读：a quarter past nine

2: 45顺读：two forty-­five     倒读：a quarter to three

21: 50顺读：twenty-­one fifty  倒读：ten to ten in the evening＝9: 50p.m.

24: 00读作：twenty-­four hundred hours＝midnight

The bus usually leaves at 19:15.  公共汽车通常在19:15离开。

(读作a quarter past seven in the evening 或nineteen fifteen)

2. 表示计量：表示事物的计量，即事物的长度、宽度、深度和高度

3. 表示编号：编号的数字如果过小，可用序数词或基数词表示；如果数字较大，通常用基数词表示

4. 表示不确切的数字：基数词后面直接加上复数名词表示精确的数字，而基数词复数形式加上“of” 表示不
