标志词：already · yet · just · ever · never
位置 + 语气 + 常见错误（本页专讲五个「小信号灯」，不展开 for/since 与口语长对话。）
上一节我们区分了两大「意义」；这一节学习五个副词，让听者知道你是刚完成、已经完成、还没完成、曾经做过还是从未做过。
五个副词：位置口诀 + 例句
本课 already 只教常见位置：have/has 之后、过去分词之前，以降低混乱。
already
Often shows something happened sooner than expected — “already done”.
- I've already read two books this summer.
- She has already finished her summer homework.
口诀：已经 → 常放在 have/has 后面，再跟过去分词。
yet
In questions/negatives: “so far / still not” — usually at the end.
- Have you chosen your club yet?
- I haven't decided on my reading list yet.
口诀：疑问、否定里的「还/尚」→ 句末；肯定陈述表「已经」请用 already。
just
“A very short time ago” — between have/has and the past participle.
- I've just finished my plan for the new term.
- We've just come back from morning running.
口诀：刚刚 → 夹在 have 与 done 中间。
ever
In questions: “at any time before now?” — before the past participle phrase.
- Have you ever tried an English corner?
- Has he ever missed a team practice?
口诀：Have you ever …? → ever 紧跟在 you 后、过去分词前，朗读时可在 ever 后轻停顿。
never
“Not at any time” — between have/has and the past participle (like “not ever”).
- I've never joined a school club before.
- She has never skipped a volunteer day.
口诀：不要写成 don't never；用 have/has + never + done。
错句诊所（错 → 正）
色盲友好：红框旁标「误」，绿框旁标「正」，并附文字图标。
Have you finished yet your homework?
错因：yet 作「还/尚」讲时，应放在句末，不要插在宾语前。
Have you finished your homework yet?
I have finished already my homework.
错因：already 通常放在 have 后，不放在宾语后面。
I have already finished my homework.
I haven't finished my homework already.
错因：否定「还没」用 yet（句末），不用 already。
I haven't finished my homework yet.
Never I have seen such a thick grammar book.
错因：never 不能单独顶在句首接现完；应放在 have 与过去分词之间。
I have never seen such a thick grammar book.

迷你对照：already 与 yet
| 语气 | 常见结构 | 例句（教材风） |
|---|---|---|
| 肯定：已经做了 | have/has + already + p.p. | We've already practised dialogue twice today. |
| 否定：还没做 | haven't/hasn't + … + yet（句末） | I haven't handed in the report yet. |
| 疑问：做了吗 / 有了吗 | Have/Has + 主语 + … + yet? | Has your group chosen a topic for the poster yet? |
提醒：肯定陈述一般不用 yet 表示「已经」，避免说 ×I have finished yet.（除非极特殊语气，本课不作要求。）
小结
- 五个副词像「信号灯」：告诉对方时间关系 + 预期（刚 / 已 / 尚 / 曾 / 从未）。
- 位置题中考常考：yet 句末、already / just / never 常在 have 后、过去分词前、ever 在疑问里 have 后。
- 初二阶段 already 与 just 分开练，避免同句堆砌造成超纲。
