1.整点表示法：It's...o'clock.
It's 9 o'clock AM.早上9点.
It's 4 o'clock PM.下午4点.
2.前半小时：
It's 10 past 5.5点10分.
It's a quarter past 9.9点15分.一刻钟 a quarter
It's half past 7.7点半.半小时 half past +点钟
3.后半小时,差...分...点
It's 2 to 11.差2分11点.
It's a quarter to 12.差一刻12点.
还有就是直译时间法：6点10分,It's six ten.
3点50分,It's three fifty.
