小结:
1.What's the exact time?
三十分钟之内的分钟数用past
2:05five past two
1:15 a quarter past one
10:30half past ten
超过三十分钟的分钟数用
“剩下的分钟+ to + 下一个钟点”
8:55five to nine
6:15 a quarter to seven
不是整五，整十的分钟数我们要在分钟数的后面加minute(s)。
4:12twelve minutes past four
8:57three minutes to nine
5:49eleven minutes to six
注意：它们前面的介词都要用at。
最简单的表达是直接读取钟点和分钟8:20eight twenty
6:30six thirty
9:55nine fifty-five
10:16ten sixteen
1:47one forty-seven
2:33two thirty-three
