表格

6:15 | six fifteen | a quarter past six |
6:30 | six thirty | half past six |
6:45 | six forty-five | a quarter to seven |
6:50 | six fifty | ten to seven |
√规则
·≤30 分钟:分钟 + past + 小时
·>30 分钟:(60 - 分钟) + to + (下一小时)
·15 分钟 = a quarter
·30 分钟 = half
时间口诀半点以前用 past,半点以后用 to;15 分钟 quarter,30 分钟 half。
