一、所有的时间都可以用“小时 + 分钟”直接读：
6:10 six ten
8:30 eight thirty
2:40 two forty
二、如果所表述的时间在半小时之内，可以用“分钟 + past + 小时”：
6:10 ten past six
4:20 twenty past four
10:25 twenty-five past ten
三、如果所表述的时间在半小时之外，可以用“（相差的）分钟 + to + （下一）小时”：
10:35 twenty-five to eleven
5:50 ten to six
9:49 eleven to ten
四、如果所表述的时间恰好为半小时，可以用“half + past + 小时”：
11:30 half past eleven
2:30 half past two
五、如果所表述的分钟和15有关，就有三种表达法：
（15分钟又叫一刻钟：a quarter）
9:15 nine fifteen ; fifteen past nine ; a quarter past nine
3:45 three forty-five ; fifteen to four ; a quarter to four
六、整点的表达：
现在是两点整。It's two./It's two o'clock.
另外英语中的 noon 和midnight 可分别直接表示白天和夜晚的12点：
It's (twelve) noon. 现在是中午十二点。
It's (twelve) midnight. 现在是半夜零点。
七、大约时间：
It's almost two. 马上到两点了。
It's not quite two. 还不到两点。
It's just after two. 刚过两点。
八、若想表明是上午，可在时间后加上a.m.
如：thirteen past six a.m.（上午六点十三分）。
若想表明是下午，可在时间后加上p.m.
如：four o'clock p.m.（下午四点）。
