搭配 “on time” 和 “in time” 都可以用来描述事情发生的时间与日程、安排之间的联系。它们当中一个表示 “按时”，另一个则表示 “及时” —— 你能分清吗？比如，“火车没有准时到站” 中的 “准时” 用哪个更恰当？
用法总结
1. “On time” 用来谈论 “按照某个设定好的计划、时刻表或者最终期限做某事”，意思是 “按时，准时”。
- If I don't finish my work on time, my boss will be angry.
- My train is never on time.
2. “In time” 用来谈论 “没有因为太迟而导致事情无法顺利进行”，意思是 “及时”。
- I missed my deadline, but I still got the presentation finished in time for the meeting.
- My train was late, but it still arrived in time for me to get to work early.
3. 如果条件和日程安排相对宽松，那么有时，虽然没有做到 “on time（准时）”，但由于做到了 “in time（及时）”，事情还是可以顺利进行。
- Neither my presentation nor my train were on time – but they were in time for me to do what I needed to do.
4. 但有时，比如在时间安排很紧的情况下，如果无法做到 “on time（准时）”，那么也就没办法做到 “in time（及时）”。
- Sometimes, if you're not on time, you won't be in time either!
