Question

In three days、three days later、after three days

In three days、three days later、after three days还有within three days,这些有什么区别，能说的具体一些吗？英语小白求助

Answer 1

假设今天是一月一日，那么这些词语所表示的日期
1. My love will come back in three days.
【一月四日；通常用于计算从现在开始的将来时；比较精确】
2. My love will come back three days later.
【一月四日；比较口语化；通常是later than me之类的省略式】
3. My love will come back after three days.
【一月四日或更晚；通常用于过去时（My love came back after three days.）；不精确】
4. My love will come back within three days.

【一月四日或更早】
辛苦整理，敬请采纳！
