(1)直接表达法：钟点+分钟
It’s eleven o’clock.
It’s seven fifteen.
(2)间接表达法
●当分钟不超过30分钟，用介词past表示，结构：分钟+past +钟点
five past nine = nine five (9:05)
fifteen past ten = ten fifteen = aquarter past ten (10:15)
thirty past two = two thirty =half past two (2:30)
●若分钟超过30分钟，用to来表示。差几分到几点，结构：分钟(60-分钟)+ to + 钟点(钟点+1)
ten to ten = nine fifty (9:50)
fifteen to five = four forty-five= a quarter to five (4:45)
【注】① 表示整点时间，直接用基数词表达，后边可接o’clock (也可不加)。表达“几点几分”时，绝不能用o’clock。
② 表达“15分”或“45分”时，常用quarter(刻)。
