Future continuous and perfect
IntroducedYour saved position stays in this browser. Resuming does not complete the lesson or answer its questions.
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.”
Difficulty 1/5 · 100 coins + a small bonus on first completion today
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.
Which interpretation fits “At three tomorrow, I’ll be interviewing applicants”?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
The continuous viewpoint places the activity around three. It neither supplies the exact starting time nor presents all interviews as completed.
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 the requested future-perfect frame with the past participle of finish: “By next year, I will have ___ my studies.”
Difficulty 1/5 · 100 coins + a small bonus on first completion today
Future perfect = will have + past participle: “will have finished”.
Can the future perfect present an action as completed by a future reference time?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
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。
Difficulty 3/5 · 200 coins + a small bonus on first completion today
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.
“By July, I’ll have known Mei for six years” necessarily says that knowing Mei ends in July.
Difficulty 1/5 · 100 coins + a small bonus on first completion today
The perfect looks back over accumulated duration from July. The state can continue; perfect does not mean that every state ends at the reference point.
What does “By Friday, we’ll have repaired the bridge” establish?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
The sentence gives a future completed-status prediction. Evidence of actual delivery would require more than the chosen verb form.
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.
Which instruction uses a complete present-perfect future time clause?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
Have read is present perfect in the future time clause. The main instruction follows that reading; future reference does not require will in this when-clause.
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 the cues to these explicitly supplied example frames: “By next year, I ___ finished”; “This time tomorrow, I ___ flying”; “when you arrive”. These are example matches, not compulsory tense choices triggered by time words.
Difficulty 2/5 · 140 coins + a small bonus on first completion today
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.”
Difficulty 1/5 · 100 coins + a small bonus on first completion today
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.
Write one English prediction using will be + -ing or will have + past participle. You may invent a practical situation; the form expresses a prediction, not proof that it will happen.
Difficulty 3/5 · 200 coins + a small bonus on first completion today
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?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
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.
Compare the intended meaning and the relevant clause/form choices. Revise one supported issue; this local self-review does not award correctness or proficiency.
Worked contrasts: what the viewpoint leaves open
- Status versus exact time: “At two, I’ll be repairing the camera; I’ll have tested the spare by then.” presents repair as ongoing and the test as complete by two. It gives neither exact starting time. “The test will finish at exactly two” adds a precision the perfect does not provide.
- Unfinished versus unstarted: “By Friday, I won’t have read all four chapters” leaves partial progress possible. “I won’t have read any of them” is a stronger claim. Accumulated state versus ending: “By July, I’ll have known Mei for six years” does not require the relationship to end in July.
Fresh decisions: read the whole frame
- Work through nineteen new independent written decisions alongside the earlier technician update: find the reference point, identify what each clause presents, and reject only the claim that changes that meaning. Choose the requested form rather than assuming other grammatical viewpoints are impossible.
- Check negatives, questions and the whole auxiliary chain. will be open describes a future state here; will be answering is the ongoing pattern; will have been repaired is perfect passive. The letters be or been alone do not settle the construction.
Supply the missing auxiliary in the requested ongoing frame: “At noon tomorrow, the crew will ___ loading the van.”
Difficulty 1/5 · 100 coins + a small bonus on first completion today
The complete frame is will be loading. Have loading lacks the participle structure of a perfect frame; do not omit be.
Supply the missing auxiliary in the requested completed-by-then frame: “By noon tomorrow, the crew will ___ shipped all the parcels.”
Difficulty 1/5 · 100 coins + a small bonus on first completion today
Will have shipped is future perfect. Shipped is the past participle; will be shipped would instead be a passive with the parcels as subject, not this crew-as-agent clause.
Use the past participle of write: “By Monday, the editor will have ___ the introduction.”
Difficulty 1/5 · 100 coins + a small bonus on first completion today
The frame needs written, not base write or past wrote. The prediction presents the introduction as complete by Monday without giving its exact completion time.
Use the past participle of know: “By September, we will have ___ each other for eight years.”
Difficulty 1/5 · 100 coins + a small bonus on first completion today
Known completes will have known. The duration accumulates by September; the friendship does not have to end then.
Read “The guests arrive at two. By then, I’ll have arranged the chairs. At two, Jo will be checking tickets.” What is the reference point for by then?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
Then refers to the stated arrival time. The chair arrangement is presented as complete by that point; ticket checking is presented as ongoing then. No purchase or leaving time is given.
What is left unspecified by “At nine tomorrow, we’ll be rehearsing”?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
At nine supplies the reference point; will be rehearsing supplies the ongoing viewpoint. Its exact start and later completion are not stated.
Which interpretation preserves “By six, I’ll have finished all three checks”?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
By gives a boundary, not an exact finishing appointment. All three fixes the scope of the predicted completion, but the sentence does not prove that the prediction will come true.
What follows from “By Friday, I won’t have read all four chapters”?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
Not have read all does not mean not have read any. The negative concerns completing all four by that point, leaving partial progress possible.
What does “At eight tomorrow, I won’t be working” leave open?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
The negative is tied to working at eight. It does not rule out work earlier or later that day or establish permanent absence from work.
Choose the complete question asking about completed status by noon.
Difficulty 1/5 · 100 coins + a small bonus on first completion today
In this question, will precedes the subject; have is followed by the past participle checked. Keep the whole auxiliary chain, not just a memorised time phrase.
A colleague asks “Will you be using the meeting room this afternoon?” What can this question do?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
Future continuous can ask about expected future activity. Grammar alone does not guarantee a courteous tone, and the question does not assert a completed past booking.
Which reading fits “Next week, I’ll be working at the south branch instead of my usual office”?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
The week gives a future period and the contrast gives a different expected arrangement. A continuous form over that period does not require uninterrupted activity every minute.
How should “By March, I’ll have owned the shop for five years” be read?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
This is accumulated duration of a state at a future reference point. It does not announce a sale or force ownership to end.
Which analysis fits “By opening time, the damaged seats will have been repaired”?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
Will have been repaired combines perfect and passive. Been is followed by a past participle here; a bare been is not evidence of a continuous construction.
Which analysis fits “The desk will be open at ten”?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
Open describes a state and is not an -ing verb here. Compare will be answering calls for the ongoing-action pattern; will be alone is not enough to label a construction continuous.
Which comparison is accurate?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
A future-simple deadline promise and a future-perfect viewpoint can overlap in practical meaning. The message and task instruction determine which form is requested; neither proves actual delivery.
The presence of by tomorrow makes every grammatical English clause use will have + past participle.
Difficulty 1/5 · 100 coins + a small bonus on first completion today
A time phrase is not a compulsory tense selector: I’ll finish by tomorrow is grammatical. Inspect the full frame and intended viewpoint rather than rejecting an alternative from by alone.
“At five, she’ll be recording the interview” gives the exact time that the recording starts.
Difficulty 1/5 · 100 coins + a small bonus on first completion today
It places recording in progress at five. It does not specify an exact starting time or whether the interview is later finished.
“By Tuesday, all the windows will have been cleaned” names the person who cleans them.
Difficulty 1/5 · 100 coins + a small bonus on first completion today
The passive presents the windows as receiving the cleaning, completed by Tuesday in the prediction. No agent is named; do not invent one from the passive frame.
Transfer: preserve a practical handoff
- Follow Rin’s loading and Mal’s completed labelling without swapping people or inventing a deadline guarantee. Repair a second update so its ongoing and completed activities match the requested plan.
- Draft your own two-line English handoff before comparing with the earlier guarded model. Identify a real status or reference mismatch and revise it. The model illustrates choices; copying it is not evidence of independent control.
Read “At two tomorrow, Rin will be loading crates. Mal will have labelled the cases by then.” Which handoff preserves the people and status?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
Attach each form to its named person and activity. Loading is ongoing, labelling complete by the shared reference point; exact finishing times and fulfilled promises are not established.
You want to present ticket checking as ongoing at four and sign printing as already complete by then. Which update preserves that request?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
The requested ongoing frame belongs to ticket checking; the completed-by-then frame belongs to printing. Do not reverse the task statuses or contradict the completed result.
Later review: one time, two viewpoints
- Tomorrow, interpret the kit-packing update and complete the new departure frame before rereading the worked contrasts. Then write the charity-room update before opening its model. Check what is ongoing, what is complete and what remains only predicted.
- Next: narrative viewpoints, proposal writing, or future-reference review. Planning time across sessions is provisional; these written checks and self-comparisons do not certify proficiency.
Usage checked 21 October 2026: British Council, future continuous and perfect. New examples/tasks are original teaching material. The unchanged diagram illustrates ongoing and completed-event viewpoints; accumulated states need the qualifications in the text. Independent specialist, language, answer, accessibility and learner review remains pending.
Later, interpret “At nine tomorrow, I’ll have packed all the kits, while Jo will be briefing volunteers.” Which summary fits?
Difficulty 1/5 · 100 coins + a small bonus on first completion today
The two activities have different viewpoints at the same reference point. Neither form supplies their exact start times, and the prediction is not a delivery receipt.
Later, supply the past participle of leave: “By the time you reach the station, the train will have ___.”
Difficulty 1/5 · 100 coins + a small bonus on first completion today
Will have left gives completed departure by the arrival reference point. Left is the participle; it is not an -ing form and does not prove that the prediction will be met.
Later, write a two-sentence English update for a charity book room tomorrow. Present cataloguing books as in progress at 16:00 and checking the display labels as complete by then. Use will be + -ing and will have + past participle. Draft before showing the model, then revise one unclear frame or status.
Compare the intended status, people and time with the model and checklist. Revise a real mismatch; several English formulations can work, and self-comparison does not establish correctness or proficiency.
