语言视角
用母语深入讲解
Aspect is central in Mandarin: 了 le, 过 guo, 着 zhe, 在 zài, result complements, and context describe completion, experience, duration, ongoingness, or change of state.
我吃过北京烤鸭。
wǒ chī guo Běijīng kǎoyā = I have eaten Peking duck before
在所学语言中
英语很重视事件的“进行、完成、持续”等状态；进行时、完成时、完成进行时会改变说话人看待事件的方式。
She has been studying.
has been studying = 表示一直在进行、并且与现在有关的事件状态
学习者常混淆一般式、进行式和完成式，尤其是现在完成时和一般过去时。
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
