英语时间通常用以下两种方法表达

英语时间通常用以下两种方法表达：钟点1. 直接表达法A. 用基数词+ o'clock来表示整点，注意o'clock须用单数，可以省略。

如：eight o'clock 八点钟，ten (o'clock) 十点钟 B. 用基数词按钟点+ 分钟的顺序直接写出时间,表示非整点，后不可加o'clock。

如：eleven-o-five 十一点过五分，six forty六点四十2. 间接表达法A. 如果分钟数少于30分钟，可用分钟+ past + 钟点表示，其中past是介词，意思是“过”。

如：twenty past four 四点二十eight past one 一点八分B. 如果分钟数多于30分钟，可用（60分钟-原分钟数）+ to +（原钟点数+ 1）表示，其中to是介词，意思是“差”。

如：8:35 可表示为twenty-five to nine 差二十五分钟九点，即八点三十五（其中的分钟数twenty-five 是由60分钟减去35分钟得到的；钟点数nine是由8加上1得到的）。

注：A. 当分钟数是15分钟时，可用名词quarter （一刻钟）表示。

如：7:15可表示为a quarter past seven，12:15可表示为a quarter past twelve B. 当分钟数是30分钟时，可用名词half （一半）表示。

如：9:30 可表示为half past nine，3:30可表示为half past three。

C. 若想表明是上午，可在时间后加上am或a.m.。

如：thirteen past six a.m. （上午六点十三分）等。

若想表明是下午，可在时间后加上pm或p.m.。

如：four o'clock p.m. （下午四点）等。

D. 若表示的时间不够准确，可在时间前加上介词about。

如：about eight （大约八点）等。

E. 在时间前面应用介词at 来表示在的意思。

如：at nine 在九点钟，at about five thirty-five p.m. 大约在下午五点三十五分等。
