考点三数词的常见表达法

时刻的表达

am 意为“上午”，pm 意为“下午”，它们不可以再与morning 和afternoon 连用。如：9:35 am=9:35 in the morning

4 pm = 4 o’clock in the afternoon

②o’clock 的用法

o’clock 之前必须是“整点”，钟点数用阿拉伯数字和英语单词表示都可以。在“时+分”的形式中，后面不可用o’clock。如：

at 9 o’clock at

ten o’clock

③时刻的读法

表达时刻通常用阿拉伯数字。读时，30 分钟以内，需借助past；超过30 分钟，需借助to；1

。如：

9:05 读作：five (minutes) past nine 或nine o five

9:25 读作：twenty-five (minutes) past nine 或nine twenty-five

11:15 读作：a quarter past eleven 或eleven fifteen
