现在完成时不是「刚刚发生」

「最近的用完成时、久远的用过去时」——这条规则是假的。

Copy the prompt, then pick a model. It plays the interviewer and asks you through it scene by scene instead of handing you the answer.

On a phone with the app installed, the system opens the app directly. Links cannot open external apps inside WeChat — open it in a browser first.

The copied text ends with the answer key the model grades you against. Don't read it yourself first — working it out on your own is the point.

这是说中文的人最持久的一个坑,因为中文没有时态标记:我们习惯用「昨天」「已经」这类词表示时间,于是感觉动词本身不用变。

这一份不给你用法列表(表示经历、表示结果、表示持续那三条是推论,直接给等于毁掉这一场),只逼一件事:你说这句话的时候,想让对方注意的是「那件事发生过」,还是「现在的结果」?

想通这一条,「为什么不能配 yesterday」就不用背了。

How to use this

This set teaches rather than interrogates: it guides you instead of pressing until you have nothing left to say. When you're stuck it first asks which layer you're stuck at (never heard of it / know it but not why / know why but can't use it), then decides what to give. Only after guiding you twice will it spell it out — and then it asks you to say it back in your own words.

**Not sliced by the textbook's table of contents.** "The 26 letters" is not about reciting the alphabet; it's about the handful of things you actually have to master before that piece is done — and that list is the answer key. Topic choice targets first-language interference: Chinese marks no tense, has no articles, and its pinyin is a one-to-one sound system. Those three facts dig the deepest holes.

How to start

  1. Pick one, open it, copy the prompt.
  2. Paste it into a brand-new conversation, say nothing, and wait for its first question.
  3. Say things out loud rather than only in your head. The speaking one runs entirely in English — you may ask for help in Chinese, but it keeps count.

Four commands you can call out at any time

  • 跳过 move to the next scene now
  • 换个说法 explain this bit again from another angle
  • 直说吧 spell the answer out, then make me say it back
  • 复盘 jump to the wrap-up and print the review card

Three traps

  • Don't read the answer key at the end first. **The speaking one is the exception** — it has no answer key, only a scoring rubric, and that rubric is meant to be read first: if you don't know what's being looked at, you don't know what to practise.
  • Don't let it write your sentences. Cut it off when it offers you a whole line — a ghostwritten sentence is one you still won't be able to produce next time.
  • When it starts praising you, point it back to the "don't praise me" rule. Guiding is not coddling.

Starting from zero: the letters, then phonics. Can read and write but freeze when speaking: go straight to the speaking one and find out which dimension is weakest. Keep being told your writing sounds off: the perfect tense and the articles. The speaking one is worth repeating, with a different topic each time.
