语言视角
用母语深入讲解
Mandarin events are centered on verbs or stative predicates, with no person or tense conjugation; aspect and context carry much of the event framing.
孩子们在玩。
háizimen zài wán = the children are playing
在所学语言中
英语句子的事件核心通常是动词；表达时态、进行、被动或疑问时，常需要助动词，如 be、have、do。
The children are playing.
are playing = 事件/动作（正在玩）
学习者可能漏掉助动词，或在需要变化的句子里直接使用词典里的动词原形。
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
