Grammar Rule in 30 Seconds
Use these three words to show how recent an action is or if it happened sooner than expected.
- Use 'just' for things that happened a moment ago: 'I've just arrived.'
- Use 'already' for things that happened sooner than expected: 'I've already finished.'
- Use 'yet' for things you expect to happen soon: 'Have you finished yet?'
Overview
Present Perfect（现在完成时）是一个非常重要的时态，它连接了过去与现在。对于我们中文母语者来说，理解这个时态的核心在于：我们不再仅仅关注动作发生的具体时间，而是关注动作对“现在”产生的影响。为了更好地表达这些微妙的心理状态，我们经常会用到 just、already 和 yet 这三个副词。它们就像是英语里的“调味品”，能瞬间让你的句子变得地道，传达出动作完成的程度、急迫感或是预期的落空。Present Perfect 结构是 have/has + past participle（过去分词），而 just、already 和 yet 的加入，则进一步细化了动作与现在的关系。很多同学在学习时会感到困惑，因为中文里我们习惯用时间状语（如“刚才”、“已经”、“还没”）来解决问题，而英语则通过副词在句子中的特定位置来体现。掌握这三个词，能帮你摆脱“中式英语”的束缚，让你在微信聊天、面试或日常交流时，表达出更精准的时间感。Present Perfect 中扮演着不同的角色，它们分别对应中文里不同的心理预期：- 1
Just：表示“刚刚”。它强调动作完成的时间非常短，几乎就在说话的一瞬间。这在中文里对应“刚才”。比如I have just finished my homework，意思是“我刚才写完作业”，那种“墨迹未干”的感觉跃然纸上。
- 1
Already：表示“已经”。它强调动作完成的时间比预期的要早，或者动作已经发生，不需要再做一遍。中文对应“已经”。比如I have already ordered bubble tea，意思是“我已经点好奶茶了”，暗示对方不用再操心或者动作提前完成了。
- 1
Yet：表示“还（没）”。它常用于疑问句和否定句，表示对某件事的预期。在否定句中，它意味着“到目前为止还没有”，在疑问句中，它意味着“你做完了吗？（我还在等结果）”。中文里对应“还没”或“吗”。
just 和 already 通常必须放在助动词 have/has 和过去分词之间。这种位置的固定性是英语语法的特点，也是我们需要刻意练习的重点。just 和 already 喜欢待在中间，而 yet 喜欢待在句尾。just | Subj + have/has + just + V-ed | I have just arrived. |already | Subj + have/has + already + V-ed | She has already left. |yet | Subj + have/has + not + V-ed + yet | I haven't seen it yet. |yet | Have/Has + Subj + V-ed + yet? | Have you eaten yet? |- 使用
just的场景：当你刚做完某事，想告诉别人最新的状态。比如在办公室，同事问你要不要一起去买咖啡，你可以说I have just had one（我刚喝过一杯）。 - 使用
already的场景：当你发现某事进展比预期快，或者想强调动作已完成。比如在淘宝购物，你想查物流，发现快递到了，你可以说It has already arrived（它已经到了）。 - 使用
yet的场景：当你关心事情的进度，或者为还没完成的事找借口。比如在大学里，教授问你的作业写好了吗，你可以说I haven't finished it yet（我还没写完）。注意，yet必须放在句尾，这是很多初学者容易忽略的规则。
- 1错误：
I have already finished my homework yesterday.
already 属于 Present Perfect，而 yesterday 是明确的过去时间，必须用 Simple Past。记住：用了 already 就不要用具体的时间状语！- 1错误：
I have not yet finished.
not yet 可以连用，但很多学生倾向于像中文语序那样把 yet 放在动词前。在英语中，yet 在否定句中通常放在句尾，放在中间听起来非常生硬。- 1错误：
Have you already finished?混淆了already和yet在疑问句中的用法。虽然already可以用于疑问句表示惊讶，但如果你只是客观询问进度，应该用Have you finished yet?而不是already。
already 和 yet，请参考下表：Already | Yet |- 1问：我可以把
already放在句尾吗？
You've finished already?，但这属于非正式用法，建议初学者先掌握放在中间的标准用法。- 1问：
just能不能用在否定句里？
I didn't just do it 或者其他表达方式，在 Present Perfect 中，否定句通常配合 yet 使用。- 1问：为什么
yet不能用在肯定句里？
yet 的核心逻辑是“预期尚未实现”。如果你在肯定句里用 yet，逻辑上是矛盾的。如果你想表达“已经完成了”，请使用 already。Placement of Just, Already, and Yet

文化笔记
British speakers are very strict about using Present Perfect with 'just', 'already', and 'yet'. Using Simple Past ('I already ate') sounds very American to them.
In the US, it is extremely common to use the Simple Past with these adverbs, especially in casual speech.
Using 'already' in a workplace can signal efficiency, but using 'yet' in a question can sometimes sound impatient if not phrased politely.
The Present Perfect construction (have + participle) developed in Old English but became standard in Middle English. 'Already' comes from 'all' + 'ready' (fully prepared).

常见问题 (8)
Yes! Use it when you are surprised. `Have you finished already?` means 'Wow, that was fast!'
`Just` is much more immediate (seconds or minutes ago). `Recently` can mean days or weeks ago.
Only as a conjunction meaning 'but' (e.g., `Yet, he didn't give up`). As a time marker, it stays at the end.
In British English, yes. In American English, it's perfectly fine. For exams, use `I've just done it`.
Because `yet` implies that the action will happen in the future, while `already` implies it happened in the past.
No, `just` as a time marker for 'a moment ago' is only for past or perfect tenses.
In the Simple Past, it goes before the verb: `I already ate`.
99% of the time, yes. In very formal English, you might see `I have not yet seen it`, but it's rare.
