Questions & Answers about tā xiàbān yǐhòu zài gōngyuán pǎobù.
Why is 下班 used by itself here? Does it need an object like 下班回家?
下班 (xiàbān) literally means “to get off work / to finish one’s work shift.”
In everyday speech, 下班 is complete by itself and doesn’t need an object:
- 我六点下班。 – I get off work at six.
- 他下班以后在公园跑步。 – He runs in the park after (he) gets off work.
You can add more information after it, but that’s a separate phrase, not an “object” of 下班:
- 下班回家 – after getting off work, (he) goes home
- 下班以后去超市 – after work, (he) goes to the supermarket
So in the sentence you gave, 下班 is already complete and natural.
What is the function of 以后 here? Is it like “later” or “after”?
以后 (yǐhòu) means “after” / “afterwards / later (than that time).”
In 下班以后, it marks the time after he finishes work. The whole chunk:
- 下班以后 = after (he) gets off work
Common pattern: Event A + 以后 + Event B
- 吃饭以后学习。 – After eating, (I) study.
- 毕业以后工作。 – After graduating, (I) work.
So here:
- 他下班以后在公园跑步。
= After he gets off work, he runs in the park.
Why is there no 在 before 下班以后? Could I say 在下班以后?
