Grammar Rule in 30 Seconds
Use the Future Simple Passive to focus on what will happen to an object, rather than who is doing the action.
- Use 'will be' + the past participle (V3) of the main verb for all subjects.
- To make it negative, use 'will not be' or the contraction 'won't be'.
- For questions, swap the subject and 'will': 'Will the work be finished?'
Overview
Future Simple Passive（未来の受動態：will be done）は、B1レベルの学習者が表現の幅を広げるために不可欠な文法です。日本語には「受動態」という概念はありますが、英語の受動態は、単なる「受け身」以上の役割を果たします。特にビジネスシーンやニュース、公式な報告など、客観性やフォーマルさが求められる場面で多用されます。日本語では「～される」という表現を日常会話で使うと、少し堅苦しく聞こえたり、被害者的なニュアンスが含まれたりすることがありますが、英語の受動態は「主語（動作の受け手）に焦点を当てる」という非常にポジティブで戦略的なコミュニケーションツールです。will be doneが力を発揮します。例えば、The new policy will be announced tomorrow（新しい方針が明日発表されます）と言うとき、誰が発表するかよりも「方針が発表されること」そのものが重要ですよね。この「情報の焦点」をコントロールする能力は、上級者へのステップアップに欠かせません。be動詞と過去分詞（V3）を組み合わせることで成立します。未来を表すwillと組み合わせると、will + be + V3という形になります。ここで重要なのは、be動詞が原形のまま固定されることです。日本語の「食べられるだろう」は「食べる」の受身＋推量ですが、英語ではwillが未来の役割を担い、beが受身の役割を担うという、役割分担が明確です。SVO（主語・動詞・目的語）の順ですが、受動態にすると目的語が主語の座に移動します。これにより、日本語でいう「主題（Topic）」を強調する効果が生まれます。The meeting will be held tomorrowと表現します。このとき、by someoneをあえて言わないことで、文が非常に洗練された響きになります。特に日本の職場や就活の面接などで、「誰がやったか」を問わずに「何が完了するか」を報告する際、この文法は非常に重宝します。Future Simple Passiveの基本構造は以下の通りです。willの後ろは必ずbe動詞の原形が来ることに注意してください。- 肯定：
The report will be finished by Friday.（レポートは金曜までに終わります。） - 否定：
The documents won't be sent until Monday.（書類は月曜まで送られません。） - 疑問：
Will the meeting be moved to another room?（会議は別の部屋に移されますか？）
be going toを使った形も非常に一般的です。「すでに決まっている未来」を強調する場合は、Subject + am/is/are + going to + be + V3を使います。willが「その場で決めたこと」や「予測」に強いのに対し、be going toは「予定」に強いという違いは、能動態と全く同じです。- 1動作の主体が重要でない場合：例えば、コンビニで「この商品は明日入荷されます」と言いたいとき、
This product will be restocked tomorrowと言うのが自然です。誰が補充するか（店員さん）は自明なので、あえて言う必要がありません。 - 2客観性を保ちたい場合：報告書や公式なアナウンスでは、個人の名前を出すよりも「物事」を主語にする方がプロフェッショナルです。
The decision will be made by the board（決定は役員会によってなされます）のように、権威やプロセスを強調できます。 - 3結果を強調したい場合：
The prize will be awarded to the winner（賞は勝者に授与されます）のように、何が起こるかという「結果」に焦点を当てたいときに最適です。
- 1
be動詞の欠落：The work will finished tomorrow.と言ってしまうミスです。これは日本語にbe動詞がないため、頭の中で「～される＝過去分詞」と直結してしまい、be動詞という「つなぎ」を忘れてしまうことが原因です。willとV3の間に必ずbeを入れる習慣をつけましょう。 - 2
willの後ろを変化させる：The report will is finished.というミスです。willの後ろは必ず「原形」です。日本語の「～するだろう」という推量の意識が強すぎると、現在形や過去形と混同しがちです。 - 3能動態と受動態の混同：
The meeting will hold tomorrow.と言ってしまうケースです。日本語では「会議を開く」と「会議が開かれる」を助詞や動詞の活用で使い分けますが、英語ではhold（開く）とbe held（開かれる）を厳密に区別する必要があります。「主語」が「動作を自分でできるか」を常に自問自答してください。会議は自分では開けないので、受動態が必要です。
Future Simple Passiveと、似たような表現を比較してみましょう。will do) | 誰がするかを強調（能動的） |will be done) | 何がされるかを強調（客観的） |is done) | 現在の習慣や事実（日常的） |will doとwill be doneの最大の違いは「焦点」です。I will finish the reportと言えば「私がやる」という責任感や意志が伝わりますが、The report will be finishedと言えば「レポートが完成するという事実」が伝わります。場面に合わせて使い分けることが、B1レベルからB2へ上がるための近道です。by + agentは必ず必要ですか？will be doneとis going to be doneはどちらを使うべき？willは予測やその場の判断、is going toはすでに決まっている予定に使います。日本語の「～するつもりです」に近い感覚でbe going toを選んでください。done, seen, writtenなど、頻出のものをリスト化して、声に出して覚えましょう。受動態の練習は、不規則動詞の習得とセットで行うのが最も効率的です。頑張ってください！Future Simple Passive Conjugation

よくある質問 (8)
Yes! You can say 'The house is going to be painted.' It follows the same logic: `be going to` + `be` + `V3`.
Not always, but it is *more* common in formal writing. In conversation, we use it for things like deliveries or services: 'My car will be fixed tomorrow.'
No. In fact, we usually omit 'by' if we don't know who did the action or if it's not important. 'The mail will be delivered' is better than 'The mail will be delivered by the mailman.'
'Will be done' is Future Simple Passive. 'Will have been done' is Future Perfect Passive, used for actions finished *before* a certain time.
No. Only 'transitive' verbs (verbs that take an object) can be passive. You cannot say 'The accident will be happened' because 'happen' has no object.
You can say 'Who will be invited?' or 'By whom will the decision be made?' (though the latter is very formal).
Yes, 'won't' is just the contraction of 'will not'. It is very common in both speaking and writing.
Because 'will' is a modal verb, and modal verbs are always followed by the base form of the next verb. The base form of 'is/am/are' is 'be'.
