2:30 two thirty
1:15 one fifteen
这时的15和30不能用a quater, half代替。
② 倒读法:与汉语顺序不同,先读“分”后说“点”。
当分钟数< 30,分钟数+past +时 7:05 five past seven
当分钟数= 30,half+past+时 9:30 half past nine
当分钟数>30,分钟数+to +时 1:55 five to two 5:35 twenty five to six
当分钟数=45或15 用a quarter表示 2:45 a quarter to three 2:15 a quarter past two
注意:只有指几点钟整时才用o’clock,如ten o’clock
