基本规则
在英语中,表示时间时常用的介词有 in、on 和 at。它们的使用取决于时间的“粒度”:
- in:用于较长的时间段,如年份、月份、季节等(例如:in 2025, in June, in summer)。
- on:用于具体的某一天或日期(例如:on Monday, on June 5th, on Christmas Day)。
- at:用于具体时刻(例如:at 3 p.m., at noon, at midnight)。
“in June” vs “on June”
✅ 正确用法:in June
We will start the project in June.
❌ 错误用法:on June(除非后面接具体日期)
✅ Correct: The meeting is on June 15th.
❌ Incorrect: The meeting is on June.
❌ Incorrect: The meeting is on June.
总结:单独说“六月”时,用 in June;如果说“六月某日”,则用 on June + 日期。
