英语有几种谈论将来的方式。本文介绍其中三种最常用的:will、be going to 和现在进行时。有时不止一种形式可行,但每种形式的含义或侧重点有所不同。在 B1 阶段,目标是感受每种形式的适用场景,并注意何时多种选择都自然。
快速导图: will = 预测或即兴决定 → be going to = 计划或可见迹象 → 现在进行时 = 有具体时间的固定安排。
三种形式并排比较
| 形式 | 结构 | 典型用途 |
|---|---|---|
| will | will + 动词原形 | 预测(意见)、即兴决定、提议、承诺 |
| be going to | am / is / are going to + 动词原形 | 事先决定的计划,基于可见迹象的预测 |
| 现在进行时 | am / is / are + -ing | 固定安排,通常有具体时间/地点/人物 |
Will——预测与即兴决定
Will 适用于两种主要情况。
1. 基于个人想法或信念的预测——常与 I think、I'm sure、I'm afraid 和 probably 等表达连用:
- I think it will be cold tomorrow.
- She*'ll** love this gift, I'm sure.*
- This project will probably take longer than we expect.
2. 说话当下做出的决定、提议或承诺——事先没有计划:
- "We've run out of coffee." — "Don't worry, I'll get some."
- That bag looks heavy — I'll carry it.
- I won't tell anyone, I promise.
否定形式是 ✅ won't(= will not),绝不是 ❌ willn't。
完整的形式、疑问句和否定句详见 Will(预测与即兴决定)。
Be going to——计划与基于迹象的预测
Be going to 也有两种主要用法。
1. 事先决定的计划和意图:
- I'm going to call the doctor tomorrow.
- They're going to move to a bigger flat.
- She*'s not going to** accept the offer.*
2. 基于可见迹象的预测——你现在看到、听到或知道的情况,已经预示了接下来会发生什么:
- Look at those dark clouds — it's going to rain.
- He's driving too fast — he's going to have an accident.
- The baby looks very pale — I think she's going to be sick.
在基于迹象的预测中,眼前的情况已经显示出接下来很可能会发生什么。这正是它与 will 预测的区别:用 will 时,你表达的是观点或信念;用 be going to 时,迹象就摆在眼前。
完整的形式表格、否定句和疑问句详见 Be going to(计划与预测)。
现在进行时——固定安排
现在进行时(am / is / are + -ing)指向将来,用于计划已经确定的情况——通常有具体时间、地点或相关人物:
- I'm seeing the dentist at three o'clock.
- We're flying to Barcelona on Friday.
- She*'s not coming** to the party.*
中文常用"打算""要""会"等词表达将来,动词本身不变形;英语则要根据"临时决定、计划、已确认安排"等选择不同形式。尤其是机票、预约、见面等已确定安排,英语常用现在进行时:We're flying to Barcelona on Friday 比 We'll fly to Barcelona on Friday 更自然。
与 be going to 的区别主要在于确认程度:现在进行时强调安排已经到位——往往已预约或确认——而 be going to 可以表达尚未与他人协调的强烈意图。实际上,两种形式对于许多计划来说往往同样自然:
- ✅ I'm going to meet Anna tonight.(强烈意图)
- ✅ I'm meeting Anna tonight.(安排,很可能已与 Anna 约好)
将来的主要标志是时间表达(tomorrow、on Monday、at six)或上下文。如果没有这些提示,现在进行时通常会被理解为此刻正在发生,而不是表示将来。

对比:同一情况,三种选择
| 情况 | 最佳形式 | 例子 |
|---|---|---|
| 对将来的观点或信念 | will | I think it*'ll** be fine.* |
| 说话当下做出的决定 | will | "I'll call her right now." |
| 事先决定的计划 | be going to | I'm going to revise tonight. |
| 预测——可见迹象 | be going to | He's going to drop that! |
| 有具体时间的日程安排 | 现在进行时 | I'm meeting her at noon. |
| 意图和安排均自然 | be going to / 现在进行时 | I'm seeing / I'm going to see the lawyer tomorrow. |
注意:对于说话当下的即兴提议或决定,will 通常是自然的选择。 ✅ "The phone's ringing." — "I'll get it." — 而非 ❌ I'm going to get it(你刚在那一刻才决定的)。
将来时间状语从句:时间连词后不用 will
三种形式共同遵守一条规则:在时间连词(when、as soon as、until、before、after、once)之后,时间状语从句中用现在形式,而不是 will 或 going to。通常是一般现在时,但现在完成时和现在进行时在某些情况下也可使用:
- ✅ I'll call you when I arrive. → 而非 ❌ when I will arrive
- ✅ She's going to leave as soon as the meeting ends.
- ✅ I'll cook while you're studying. (现在进行时——正在进行的动作)
- ✅ Call me after you've finished. (现在完成时——强调完成)
这条规则适用于时间状语从句,而非间接疑问句:✅ I don't know when he will arrive 是正确的,因为 when 在这里表示"在几点"。
详情见 将来时间状语从句。
Will 与 be going to:预测时的重叠
两者都可以表达预测,界限有时模糊。更清晰的区分:
- Will → 基于观点、信念或常识的预测:There will be more electric cars in ten years.
- Be going to → 基于眼前可见迹象的预测:Look — that shelf is going to fall!
在中间地带,两者往往都可接受:✅ It'll be cold tomorrow 和 ✅ It's going to be cold tomorrow 都是自然的天气预测表达。
常见错误
- ❌ I'm going to answer it — the phone's ringing. → ✅ I'll get it.(即兴决定 → will)
- △ We'll fly to Rome on Saturday 是可以的,但若机票已预订,✅ We're flying to Rome on Saturday 听起来更自然(已确认的安排 → 现在进行时)。
- ✅ I think it'll rain 和 ✅ I think it's going to rain 都是自然的天气预测表达。当迹象明显时用 be going to:Look at those clouds — it's going to rain.
- ❌ She'll meet the client when she will arrive. → ✅ She'll meet the client when she arrives.(时间状语从句中不用 will)
- △ I'll go to the gym tomorrow 是可以的,但若课程已预约,✅ I'm going to the gym tomorrow 或 ✅ I'm taking a class tomorrow 听起来更自然。
不是错误:✅ Look — he's going to drop it! ——这是正确的。有可见迹象 → be going to 正是合适的选择。
快速练习
will、be going to 还是现在进行时,哪种形式最合适?
- That glass is right on the edge of the table — careful, it ____ (fall)!
- "I'm thirsty." — "I ____ (get) you some water."
- They ____ (have) dinner with the Nguyens on Saturday — they've already made a reservation.
- I ____ (probably / not enjoy) the film, but I'll go anyway.
- When she ____ (finish) the report, she'll email it to you.
显示答案
- is going to fall ——可见迹象(杯子在桌边)→ be going to
- 'll get(will get)——即兴、未经计划的决定 → will
- are having(they're having)——已预订的安排,带具体时间 → 现在进行时
- probably won't enjoy ——基于观点的预测。在肯定句中,probably 通常放在 will 之后:I'll probably enjoy it. 在否定句中,通常放在 won't 之前:I probably won't enjoy it.
- finishes ——when 引导的时间状语从句中用一般现在时(时间状语从句不用 will)
要点总结
- Will(will + 动词原形):基于观点的预测(I think it'll rain);对于即兴提议或说话当下的决定,will 是自然的选择(I'll get it);也用于承诺。
- Be going to(am / is / are + going to + 动词原形):事先决定的计划(I'm going to study tonight),基于可见迹象的预测(It's going to fall!)。
- 现在进行时(am / is / are + -ing):固定安排,通常有具体时间或地点(I'm meeting her at noon)。
- Be going to 和现在进行时在表达计划时经常重叠;现在进行时强调安排已经确认。
- 在 when、as soon as、until 等引导的时间状语从句中,用现在形式——通常是一般现在时,但现在进行时和现在完成时也可使用。时间状语从句中不用 will。
