HSK 1 动态助词：了

动态助词：了

The aspect particle 了 (le): completed action

⚠ English trap 母语陷阱

English “-ed” is about PAST TIME; 了 is about completion and “what this means now”. 昨天我没吃饭 has no 了 — past without it; 明天吃了饭再去 has it — future with it.

Fix: Ask “is the event completed / does its result matter now?”, not “is it past?”.

How it works 讲解

Verb + 了 marks the action as completed or realized: 我买了三本书. It answers 'did it happen', not 'when'. In negation 了 drops out: 我没买书.
