顺读法（直读法）：最基础、通用的表达，直接

“小时+分钟”

的顺序朗读，适用于所有时间点规则：整点：小时+o'clock（o'clock可省略，口语中常用）非整点：直接读小时数字+分钟数字时间英文表达中文释义7:00七点9:15九点十五12:30十二点半4:58四点五十八seven(o'clock)ninefifteentwelvethirtyfourfifty-eight英语时间表达：顺读法&逆读法

逆读法（间接法）借助past（过）和

to（差）来表达，仅适用于分钟数≤30

或

＞30的情况规则：整点：小时+o'clock（o'clock可省略，口语中常用）

非整点：直接读小时数字+分钟数字时间范围结构公式关键说明分钟数≤30分钟数+past+小时数表示“几点过几分”分钟数＞30(60-分钟数)+to+(小时数+1)表示“差几分到下一点”15分钟用
