现在完成时:在句末使用 'yet'

Use yet at the end of present perfect negatives and questions for expected but unfulfilled actions.

Grammar Rule in 30 Seconds

Use 'yet' at the end of sentences to talk about things you expect to happen soon but haven't happened.

  • Use 'yet' at the end of negative sentences: 'I haven't eaten yet.'
  • Use 'yet' at the end of questions: 'Have you finished yet?'
  • Never use 'yet' in affirmative (positive) sentences; use 'already' instead.
Subject + haven't/hasn't + Verb (V3) + ... + ⌛ YET?

Overview

曾经在一分钟内刷了五次快递查询页面吗?你知道包裹在路上,只是它还没有到达 yet。这个小小的词 yet 简直是英语语法里的“终极等候室”。它总是待在句子的最后。它向别人发出信号:你正期待着某件事快点发生。没有它,句子感觉没写完;有了它,你听起来就像个地道的母语使用者。
yet 是一个配合 Present Perfect(现在完成时)使用的时间(shíjiān)副词。你用它来谈论那些直到现在还没发生的事情。它也能帮你询问预期的事是否已经发生了。它是连接过去和当下这一秒的桥梁。它暗示着动作很可能在未来发生。把它想象成 YouTube 视频上的“加载中...”语法版。它给你的话语增添了一层期待或不耐烦的感觉。在 B1 级别,掌握 yet 是一个巨大的里程碑。它让你告别简单的过去时句子,让你能够描述正在进行的生活状况和待办事项。

How This Grammar Works

在英语里,语序决定一切。对于这条特定的规则,yet 最喜欢在句尾抢占风头。你几乎总能发现它是句子的最后一个词。它专门混迹于两类句子中。第一,出现在否定陈述句里;第二,出现在疑问句里。它不喜欢肯定句。如果你说
I have eaten yet,
别人会听得一脸懵逼。它对听者来说就像个信号灯,在说:“我还在等这个情况发生改变。”这就像在看手机等短信一样。你还没收到它 yet,但你一直在盯着看。

Formation Pattern

1
造这些句子有一套非常严格的“菜谱”。按照这些步骤做,保证每次都正确:
2
从你的主语 subjectI, You, We, They, He, She, It)开始。
3
加上助动词 havehas。第三人称单数用 has
4
对于否定句,加上 not。通常我们使用缩写 haven'thasn't
5
使用主要动词的 Past Participle(过去分词,例如 seen, done, gone)。
6
yet 放在句子的最末尾。
7
Negative Formula: Subject + haven't/hasn't + past participle + yet.
8
Question Formula: Have/Has + subject + past participle + yet?

Conjugation Table

Form Example Translation
Negative (I/You/We/They) I haven't seen the finale yet. 我还没看大结局呢。
Negative (He/She/It) She hasn't replied to my DM yet. 她还没回我的私信。
Question (I/You/We/They) Have you finished the level yet? 你这关过完了吗?
Question (He/She/It) Has the bus arrived yet? 公交车到了吗?

When To Use It

当你追踪进度时就用 yet。它非常适合谈论家务或工作任务。当你等待某人或某事时也可以用它。在社交媒体场景下也很棒。你发那个 抖音(TikTok)yet?如果你还没发,你的粉丝可能会觉得无聊哦。当你感到一点压力或紧迫感时用它。在 Zoom 上的面试里也很常见:“你用过这款软件 yet?”它还是旅游博主界的王者:“我们还没到达顶峰 yet,快看这景色!”它把简单的“不”变成了“目前还没”。

Politeness Levels

Social Context | Sentence | Tone

Casual (给朋友发短信) | Haven't finished the show yet. | 非常非正式,省略了主语。

Neutral (标准对话) | I haven't finished my homework yet. | 友好且清晰。

Formal (工作面试/电子邮件) | We have not received the documents yet. | 严肃,不使用缩写。

Memory Trick

yet 想象成一个 Yelling End Tool(大喊大叫的句尾工具)。它待在句子的 End(末尾)。它 Yells(大喊)出你还在等某件事。它就像一只蹲在门口的狗,它还没去散步 yet,但它已经准备好了。

Common Mistakes

别把 yet 放在肯定句里。避开像
I have seen the movie yet
这样的说法。相反,对于肯定的好消息要用 already。另一个大错误是把 yet 放在中间。"I haven't yet seen it" 虽然可行但非常正式。对于 B1 英语,把它放在结尾最保险。另外,别把 yetstill 搞混了。still 通常放在动词前面。yet 则属于终点线。如果你把它放错了位置,听起来会像个机器人。一个出了点故障的机器人。别当那个机器人。

Contrast With Similar Patterns

容易混淆

Present Perfect: Using 'yet' at the end 对比 Yet vs. Already

Learners use 'yet' in positive sentences because their native language uses the same word for both.

Present Perfect: Using 'yet' at the end 对比 Yet vs. Still

Both imply an unfinished action, but 'still' emphasizes the duration and 'yet' emphasizes the expectation.

Present Perfect: Using 'yet' at the end 对比 Yet vs. Just

'Just' is for very recent completions, while 'yet' is for non-completions.

常见错误

I have finished yet.

I have already finished.

You cannot use 'yet' in a positive sentence.

I not finished yet.

I haven't finished yet.

You still need the auxiliary verb 'have/has'.

Have you finish yet?

Have you finished yet?

You must use the past participle (V3), not the base form.

I haven't yet eaten.

I haven't eaten yet.

While 'yet' can move in formal English, at A1/B1 it should stay at the end.

Did you finish yet?

Have you finished yet?

In standard English, 'yet' requires the Present Perfect, not Past Simple.

She hasn't yet arrived.

She hasn't arrived yet.

Keep 'yet' at the end for natural-sounding neutral English.

I haven't seen him already.

I haven't seen him yet.

Using 'already' in a negative sentence is rare and usually means something else.

I haven't still finished.

I haven't finished yet.

Still usually goes before the verb, yet goes at the end.

Has he yet to arrive?

Has he arrived yet?

'Has yet to' is a very formal structure and shouldn't be used in casual questions.

I haven't never seen it yet.

I haven't seen it yet.

Double negatives (haven't + never) are incorrect.

The results haven't been yet published.

The results haven't been published yet.

The 'Already' Swap

If you can't decide between 'yet' and 'already', try making the sentence positive. If it works with 'already', the negative version needs 'yet'.
⚠️

American vs British

If you are taking an exam like IELTS or Cambridge, always use 'Have you... yet?' rather than 'Did you... yet?'
🎯

Polite Refusal

Use 'not yet' as a polite way to say no to an offer or a question about a task. It sounds much better than just 'No'.
💬

Impatience

Be careful with your tone. Asking 'Are we there yet?' repeatedly is the classic sign of an impatient child!

Smart Tips

Always add 'yet' to the end to sound more helpful and positive.

Be careful! At the start of a sentence, 'Yet' usually means 'But' or 'However'.

Use 'have yet to' + base verb instead of 'haven't ... yet'.

发音

Look at your to-do list. Say out loud three things you haven't done yet using the Present Perfect.

文化笔记

British speakers are very strict about using the Present Perfect with 'yet'. Using the Past Simple ('Did you do it yet?') sounds very American to them.

In casual American speech, the Past Simple is frequently used with 'yet'. It is not considered 'wrong' in conversation, but the Present Perfect is preferred in writing.

Using 'yet' in a professional context shows that you are aware of a deadline or expectation. It sounds more proactive than a simple 'no'.

From Old English 'giet' or 'gyta', meaning 'at this time' or 'hitherto'.

常见问题 (8)

Generally, no. In standard English, we use `already` for positive sentences. However, in very formal English, you might see `I have yet to...`, but this actually has a negative meaning (I haven't done it).

`Not yet` is neutral and focuses on the expectation. `Still not` often sounds more frustrated or surprised that something is taking so long. Example: 'I haven't finished yet' (Neutral) vs 'I still haven't finished!' (Frustrated).

It is not wrong in American English conversation. However, in British English and on international exams like the TOEFL or IELTS, you should use the Present Perfect: `Have you finished yet?`.

In 99% of cases, `yet` goes at the very end of the sentence or clause.

No, we don't usually use `yet` with the Present Continuous. We use `still` for ongoing actions. Example: 'I am still working' (not 'I am working yet').

It's a very common and polite way to say 'No, but it will happen soon.' It's much more natural than just saying 'No' when someone asks if you've finished something.

It doesn't change the verb's meaning, but it changes the *aspect* of the sentence, adding the feeling of 'up to now' and 'future expectation'.

Yes, it is very common in formal reports to indicate that data is not available or a decision hasn't been made. Example: 'The results have not been verified yet.'
