1.年、月、日的表示法
与汉语不同,英语中表示日期的顺序通常为“月—日—年”,也可以按“日—月—年”的顺序表示。“年”用基数词来表示;“月”用英语中表示月份的名词;“日”用基数词或序数词表示都可以。如:
1985年9月2日 September 2(nd), 1985

用“基数词+ o’ clock”表示,其中“o’ clock”可以省略。如:
7:00 seven (o’ clock)
(2)半点的表示法
用“钟点数+ thirty”或“half past +钟点数”表示。如:
3:30 three thirty/ half past three
(3)几点几分的表示法
①用“钟点数+分钟数”表示。如:
8:15 eight fifteen
②分钟数在30分钟以内,用“分钟数+ past +钟点数”表示,意为“几点过几分”。 如:
9:10 ten past nine
③分钟数超过30分钟,用“(60-分钟数)+to+下一个钟点数”表示,意为“差几分几点”。如:
2:50 ten to three
另外,数词还可用来表示年龄、长度、分数等。
