When to use Time-Interval Complements
Read verb + time since completion as a sentence tool, not just as vocabulary. First locate the main action or claim, then ask what 以后 adds to it.
这个句子里的以后让意思更清楚。
The 以后 in this sentence makes the meaning clearer.
如果不用以后，句子的重点会不一样。
Without 以后, the sentence focus would be different.
他说得很自然，因为他知道以后的位置。
He spoke naturally because he knew where 以后 belongs.
Common traps
- Do not translate verb + time since completion mechanically from English; check the Chinese word order first.
- Keep 以后 close to the part of the sentence it controls.
- Do not overuse the pattern in every sentence; use it when it adds a clear role.
