Future continuous and perfect
導入済み保存した位置はこのブラウザに留まります。再開してもImplementedの完了や回答にはなりません。
Two future viewpoints
- Will be doing and will have done let you present an activity from different future viewpoints. They are often called future continuous and future perfect.
- Outcome: distinguish what is in progress from what is completed by a reference point, without choosing a form from a time word alone.
- Start with future reference. Starting check: does I’ll send it by Friday need have sent to be grammatical? It is already a grammatical deadline promise.
By tomorrow, I will have finished the project; my printer may still be considering it.
Future continuous — will be + -ing
- This time tomorrow, I’ll be flying to Paris presents the flight as in progress at that future moment.
- The form can also describe expected or temporary future activity: I’ll be working at the north office next week.
- Will you be using the car tonight? can ask about an expected plan. Its suitability and politeness depend on the situation, not the verb form alone.
Choose the form that explicitly presents the flight as in progress at that moment: This time tomorrow, I ___ to Paris.

Will be flying gives the requested ongoing viewpoint. Will fly can also be a grammatical announcement or prediction; the time phrase alone does not make it wrong.
Future perfect — will have + past participle
- They will have left by the time you arrive looks back from arrival and presents their departure as complete by then.
- The pattern also works with states or accumulated duration: By June, I’ll have known Jo for ten years. Knowing Jo need not end in June.
- Check the participle: will have finished, not will have finish. A future-perfect prediction is still a prediction, not proof of the event.
In progress, or already finished?
Interpret the ongoing or completed-by-then viewpoint explicitly used in each example. Time words alone do not force either form.
Complete: By next year, I will have ___ (finish) my studies.

Future perfect = will have + past participle: “will have finished”.
Can the future perfect present an action as completed by a future reference time?
難易度 1/5 · 100 コイン + 今日初回完了時に小ボーナス付与
Yes: “I will have sent it by noon” presents sending as complete by noon. The form also works with accumulated states/duration; it does not mean every state has ended by that point.
Translate into English, practising will have + past participle for the completed-by-then viewpoint: 到明年,我就会完成学业了。

Will have finished gives the viewpoint requested here. “I will finish my studies by next year” is also grammatical English but uses a different form from this exercise’s explicit instruction.
Time phrases do not choose the verb for you
- By sets a deadline or reference boundary: I’ll send the form by noon and I’ll have sent the form by noon are both grammatical.
- The first promises an action by the deadline. The second explicitly looks back from noon at its completed status. Their practical meanings can overlap.
- A future time clause commonly uses a present form: by the time you arrive. It need not always be present simple: when you’ve finished, call me is also grammatical.
Make the intended viewpoint clear
- By 2030, I will finish my degree is grammatical; do not label it wrong just because it contains by. Use will have finished when you want the completed-by-then viewpoint.
- This time tomorrow I will fly to Paris can announce a future flight. I’ll be flying more explicitly presents the activity as in progress then.
- Near miss: At six, we’ll have eaten, so we’ll still be in the middle of that same meal conflicts with its completed-meal meaning. For an ongoing meal use we’ll be eating; for a finished meal revise the second claim instead.
Match these cues to the example patterns used here: “By next year, I ___ finished”; “This time tomorrow, I ___ flying”; “by the time you arrive”. These are example matches, not compulsory tense choices triggered by by or this time.

The completed-by-then example uses will have + participle; the ongoing-flight example uses will be + -ing; you arrive is present simple. Time phrases permit other grammatical viewpoints, and future time clauses can also contain present perfect.
Choose the form that explicitly shows us in the middle of dinner at 8:00: “Don’t call at 8:00 — we ___ dinner.”

Will be having presents dinner in progress. Will have had instead presents it as completed by a reference time. Will have can make a future meal prediction, but it does not explicitly supply the ongoing viewpoint requested here.
- Locate the future reference point and the intended viewpoint. Keep valid alternatives when they fit the message.
- Use will be + -ing for an ongoing activity, and will have + participle to look back at completion or accumulated duration by then.
- Later recall: make a new two-line schedule showing one task in progress and another complete at the same time. Revisit the fresh tasks from memory, then try narrative viewpoints and explain how their reference point differs.

Example: “By 2030, cars will have become much cleaner.”
For tomorrow’s open day, the technician says, “At ten, I’ll be testing the lights. I’ll have checked the fire doors by then.” Which interpretation follows from those chosen verb forms?
難易度 1/5 · 100 コイン + 今日初回完了時に小ボーナス付与
Will be testing gives the ongoing viewpoint at ten. Will have checked looks back from that point at a completed check. Neither sentence gives an exact start time or proves the plan will happen. If you reversed the tasks, attach each verb phrase to its own activity, then sketch ongoing versus completed status.
You are helping at an event tomorrow. Write a two-sentence English update for a colleague: present one activity as in progress at 11:00 and a different activity as completed by then. Use will be + -ing and will have + past participle. Invent practical details; after comparing, revise one unclear reference or form.
