未来完了進行形（Future Perfect Progressive）
未来完了進行形（Future Perfect Continuous）は、未来の特定のポイント前に、ある期間の間進行していた行動を表します。その将来の瞬間までの活動の継続期間を強調します。
未来完了進行形はwill have been +動詞の-ing形で構成されます。すべての主語（I、you、he、she、it、we、they）に同じ形が使われます。
作り方
肯定文
未来完了進行形はwill have been + 動詞-ingで作ります。短縮形（'ll）は話し言葉では一般的です。
| 完全形 | 短縮形 |
|---|---|
| I will have been walking for two hours by noon | I'll have been walking for two hours by noon |
| You will have been running all morning | You'll have been running all morning |
| He will have been cooking dinner for an hour | He'll have been cooking dinner for an hour |
| She will have been studying for three hours | She'll have been studying for three hours |
| It will have been raining all day | It'll have been raining all day |
| We will have been waiting for ages | We'll have been waiting for ages |
| They will have been working here for five years | They'll have been working here for five years |
否定文
'will'の後に'not'を加えて否定文を作ります。短縮形'won't'がよく使われます。
| 完全形 | 短縮形 |
|---|---|
| I will not have been walking for two hours by noon | I won't have been walking for two hours by noon |
| You will not have been running all morning | You won't have been running all morning |
| He will not have been cooking dinner for an hour | He won't have been cooking dinner for an hour |
| She will not have been studying for three hours | She won't have been studying for three hours |
| It will not have been raining all day | It won't have been raining all day |
| We will not have been waiting for ages | We won't have been waiting for ages |
| They will not have been working here for five years | They won't have been working here for five years |
はい/いいえの質問
主語の前に'will'を置いてはい/いいえの質問を形成します。

- Will he have been cooking dinner for an hour?

- Will it have been raining all day?

疑問詞の質問
疑問詞で始めて、その後will +主語+ have been +動詞-ingを使います。
例文：
- What will I have been doing by noon?
- Where will you have been running?
- How long will he have been cooking?
- Why will she have been studying for so long?
- When will it have been raining?
- How long will we have been waiting?
- How many years will they have been working here?
