未来進行形 (will be -ing)
Grammar Rule in 30 Seconds
The Future Continuous describes actions that will be in progress at a specific moment in the future.
- Use 'will be' + verb-ing for all subjects. Example: 'I will be sleeping at midnight.'
- Use it for actions interrupted by another event. Example: 'I'll be waiting when you arrive.'
- Avoid using it with stative verbs like 'know' or 'want'. Example: 'I will be knowing' is wrong.
Overview
Will you use the office?(オフィスを使いますか?)と言うのと、Will you be using the office?(オフィスを使っている予定ですか?)と言うのでは、相手に与える印象が大きく異なります。後者の方が、相手の予定を尊重する「柔らかい」響きになります。このように、未来進行形をマスターすることは、英語のコミュニケーションにおける「洗練さ」を手に入れることに他なりません。- Simple Future (will): 未来の「点」としての行為。決意や予測を表す。
I will study tonight.(今夜、勉強します。=勉強するという意思・事実)- Future Continuous (will be -ing): 未来の「線(期間)」の中にある特定の瞬間。動作の継続を強調する。
I will be studying at 9 PM tonight.(今夜9時は、勉強している最中です。=9時の時点では勉強が進行中)
at 5 o'clock, this time tomorrow, when you arrive といった時間表現と一緒に使われることで、その瞬間の「背景」としての動作が浮き彫りになります。また、未来進行形は「自然な成り行き」を表現するのにも適しています。個人の強い意志というよりも、「スケジュール上、当然そうなっているだろう」という客観的なニュアンスが含まれるため、ビジネスでの予定確認などに非常に重宝されるのです。will + be + 現在分詞(verb-ing) です。Subject + will be + verb-ing の形をとります。短縮形の 'll be は会話で非常によく使われます。I / We | will be working | I'll / We'll be working | I'll be working late tomorrow. |You | will be sleeping | You'll be sleeping | You'll be sleeping by then. |He / She / It | will be raining | It'll be raining | It'll be raining all day. |They | will be waiting | They'll be waiting | They'll be waiting for us. |will の直後に not を入れます。短縮形の won't be が一般的です。I will not be using the car this weekend.We won't be having a meeting next Monday.
will を主語の前に出します。be + verb-ing の部分は切り離さず、主語の後に置きます。Will you be staying at the Hilton?(ヒルトンに滞在される予定ですか?)Will they be joining us for dinner?(彼らは夕食に来るでしょうか?)
What, Where, Why など)を文頭に置き、その後に疑問文の語順を続けます。What will you be doing this time next year?(来年の今頃、あなたは何をしていますか?)Where will she be working after graduation?(卒業後、彼女はどこで働いているでしょうか?)
This time tomorrow, I'll be lying on a beach in Okinawa.
Don't call me at 8 PM. I'll be watching the football match.
They will be waiting for you when your train arrives at the station.
I'll be cooking dinner when you get home.
While you are studying in the library, I'll be working at the cafe.
Will you...? は時に「〜してくれますか?」という依頼や、「〜するつもりですか?」という強い意志の確認に聞こえることがあります。未来進行形を使うことで、「あなたの予定の自然な流れとして、〜することになっていますか?」というニュアンスになり、相手にプレッシャーを与えずに尋ねることができます。Will you be using the photocopier for long?
Will you be staying for the after-party?
I'll be passing the post office on my way home, so I can mail this for you.
The CEO will be visiting our branch next month.
be の脱落will の後に直接 -ing を置いてしまうミスです。- Error:
I will working tomorrow. - Correction:
I will be working tomorrow. - 解説: 日本語では「明日、働いている」のように「いる」を省略しても通じることがありますが、英語の進行形には必ず
be動詞が必要です。willは助動詞なので、その後のbeは必ず原形になります。
- Error:
I will be knowing the result tomorrow. - Correction:
I will know the result tomorrow. - 解説:
know,believe,understand,want,belongなどの状態動詞は、動作ではなく「状態」を表すため、進行形にはできません。これは現在進行形と同様のルールですが、未来のことになるとつい忘れてしまいがちです。
- Error:
By 9 PM, I will be finishing my report. - Correction:
By 9 PM, I will have finished my report. - 解説: 「9時までには(完了)」と言いたい場合は未来完了形を使います。未来進行形を使うと「9時の時点では、まだ仕上げの作業をしている最中だ」という意味になります。日本語の「〜している」が、完了後の状態(例:結婚している)と進行中の動作(例:走っている)の両方を表せるために起こる混乱です。
I'll call you later. (あとで電話するね)I'll be calling you at 7. (7時頃に電話している最中だと思うよ)I'll have called everyone by 7. (7時までには全員に電話し終えているよ)I'm meeting him tomorrow. (明日彼に会うことになっている)I am meeting...)は、すでに手帳に書き込まれているような「確定した予定」を指します。一方、未来進行形(I will be meeting...)は、それよりも少し客観的で、「予定としてそうなっているだろう」という予測に近い響き、あるいは単にその時の状況を描写するニュアンスになります。be going to be -ing という形も使えますか?I'm going to be working all weekend. のように言えます。will be -ing よりも「事前の意図や計画」がより強く感じられますが、日常会話では will be -ing の方が簡潔で好まれます。Will you be...? を使うのは失礼ではありませんか?will have been -ing)を使うのが適切です。未来進行形はあくまで「その瞬間の進行状況」にフォーカスします。I'll be -ing... と口に出してみることから始めてみてください。この小さな積み重ねが、B2レベルからC1レベルへの大きな一歩となります。頑張りましょう!Conjugation of 'To Work' in Future Continuous

間違えやすい
Learners often use Future Simple for everything. They forget that Future Continuous adds a sense of 'being in the middle' of something.
Both can be used for plans. Present Continuous is for fixed arrangements; Future Continuous is for actions in progress at a time.
One is about duration; the other is about completion.

文化メモ
British speakers often use 'shall' instead of 'will' with 'I' and 'we' in formal writing, though 'will' is now standard everywhere.
Using the Future Continuous is a key way to 'soften' business communication. It sounds less aggressive than the Future Simple.
Asking 'Will you be staying for dinner?' is considered more polite than 'Are you staying for dinner?' because it implies the guest has no obligation.
The use of 'will' as a future marker comes from the Old English 'wyllan', meaning 'to wish' or 'to want'. The continuous aspect (-ing) developed later to provide more descriptive power to the language.

Yes, but only with 'I' and 'we'. It is very formal and mostly used in British English. Example: `I shall be waiting.`
They are very similar. `I'll be doing` is more common for predictions and routines, while `I'm going to be doing` emphasizes a strong intention or a plan already made.
Because `know` is a stative verb. Stative verbs describe a state of being, not a physical action. You can't be 'in the middle' of a state.
Use Future Continuous when you want to emphasize that an action takes time or will be happening at a specific moment. Use Future Simple for facts, promises, or quick decisions.
Yes! It's very common. `It will be snowing tomorrow` sounds more descriptive than `It will snow.`
Absolutely. It's perfect for parallel actions: `I'll be cooking while you'll be cleaning.` (Though often the second verb is Present Continuous: `while you are cleaning`).
Yes, it's the 'polite' tense. `We will be sending the files` sounds softer than `We will send the files.`
Common markers include `this time tomorrow`, `at [time]`, `all day`, `next week`, and `while`.
