Talking about the future — a review
- English uses several forms for future reference: will, be going to, the present continuous and the present simple. Their uses can overlap.
- Outcome: explain a future choice from the speaker's meaning and context. Start with future plans. Starting check: does tomorrow alone tell you which form to use? No.
I am meeting my friend tomorrow; my calendar insists on a time.
will vs be going to
- Will can introduce a decision made now, a promise or a prediction: The chairs look heavy. I'll help you. Be going to can express an existing intention: We're going to repaint the room.
- Both can make predictions: I think the team will win; Look at that loose shelf — it's going to fall. Present evidence can motivate going to, but it does not make every will prediction wrong.
Present continuous for arrangements
- The present continuous can present a future arrangement: I'm meeting the doctor at three. We're flying on Friday. A booking or agreement helps explain the choice; a time phrase alone does not establish one.
- We're going to fly on Friday can also describe the same plan. Neither form guarantees it will happen. Timetables often use the present simple: The train leaves at six.
Which future form fits?
Read the form and intended meaning in these examples; future uses can overlap.
An arrangement: I ___ meeting the doctor at three. (am / will)

Am completes the requested present-continuous frame am meeting. Will meeting is incomplete: will would need be before meeting or a base verb such as meet. Other complete future frames can describe arrangements too.
Time clauses: when, as soon as
- In an ordinary future-time clause, use a present form: I'll call you when I arrive. Wait until the rain stops. A present perfect can mark completion: I'll send the file when I've checked it.
- An indirect question is different: I don't know when the train will arrive. Here when introduces the unknown arrival time, not the time at which another action will happen. Do not remove will just because when appears.
In this ordinary future-time clause, choose: I’ll call you when I ___ home.

Get locates the promised call at the future arrival time. This is a time clause, not an indirect question. Compare I don’t know when I will get home, where will is natural inside the unknown-time question.
For the ordinary future-time meaning “we will eat immediately after his arrival,” is this standard form correct? “As soon as he will arrive, we will eat.”

Use As soon as he arrives, we will eat for this ordinary time clause. This does not ban will from every clause containing a time word: I wonder when he will arrive is an indirect question.
Translate into English: 我到了就给你打电话。

I’ll call you when I arrive is one natural promise. The ordinary time clause uses arrive. Another appropriate future main-clause frame can fit; the translation does not test will only.
Common mistakes
- Use a complete frame: I will meet him or I am meeting him, not I will meeting him. I will be meeting him is another grammatical frame with be.
- What are you doing tonight? asks naturally about plans; What are you going to do tonight? can also fit. A future time does not select only one form.
- In the ordinary time clause in I'll wait until she arrives, use arrives. In Do you know when she will arrive?, the whole sentence asks for information; will is grammatical inside the indirect question.
Match each guided situation to the conventional teaching form in this exercise. These are model pairings, not the only possible future wording.
難易度 2/5 · 140 コイン + 今日初回完了時に小ボーナス付与
The model pairings highlight a decision now (will), an arrangement (present continuous), an intention (going to) and a timetable (present simple). Their uses overlap. A booking can also be described as an intention, and a future time alone does not prove which form is required.
Use the present simple of arrive in this future-time clause: I’ll call you as soon as I ___ .
難易度 1/5 · 100 コイン + 今日初回完了時に小ボーナス付与
Arrive is the requested present simple and fits the ordinary future-time clause. Other present frames can fit other contexts, such as as soon as I have arrived; the supplied frame here asks for the simple form.
- Choose from the intended decision, prediction, intention, arrangement or schedule; these are useful contrasts, not exclusive boxes.
- Read what the when clause does. An ordinary future-time clause differs from an indirect question about a time.
Write one sentence about a fixed arrangement you have, using the present continuous for the future.

Example: “I am seeing my friends on Saturday.”
Worked contrasts: read the evidence
- Offer now: a colleague drops a pile of folders. I'll pick those up presents a decision as you speak. I'm going to pick those up can express an intention too; it does not automatically prove the intention was made yesterday.
- Same booking, two views: you have reserved a table for Thursday. We're eating there on Thursday presents an arrangement; We're going to eat there on Thursday presents your plan. Both fit. Neither sentence proves the restaurant cannot cancel.
- Two jobs for when: I'll text you when the gate opens locates your text in time. I wonder when the gate will open asks about an unknown opening time. The second has no promise to text, and the first is not an indirect question.
Mina has booked a study room for Tuesday. She says either “We’re meeting there on Tuesday” or “We’re going to meet there on Tuesday.” Which interpretation fits?
難易度 1/5 · 100 コイン + 今日初回完了時に小ボーナス付与
The booking supports an arrangement, and the intended meeting is also a plan. The two forms can overlap; neither guarantees a future event. Repair: separate what the speaker plans from what is certain to happen. Fresh check: explain a reason that a booked event could still be cancelled.
Apply and review
- Write an original message about an arrangement. Keep the arrangement, future reference and full verb frame clear; do not rely on one time word.
- Later, without the examples, write one future-time clause and one indirect question about a future time. Explain why their verb choices can differ. Continue with first and second conditionals. These short checks are not a full independent practice bank.

A ferry has no announced departure time. Your friend says, “I don’t know when it will leave.” What does the when-clause do?
難易度 1/5 · 100 コイン + 今日初回完了時に小ボーナス付与
The friend is uncertain about the departure time: this is an indirect question about when. It does not locate a promised action at that time. Will can remain. Repair: contrast I’ll wave when it leaves, where the when-clause locates the waving. Fresh check: write an indirect question about a future opening time.
Facts: you and a classmate have agreed to meet at the library at four tomorrow. The room number is not known yet. Write a 2–3 sentence English message using the present continuous for the meeting and an indirect question with when or where about missing information. Do not invent a room number or guarantee that nothing can change. Compare, then revise one verb frame or unsupported detail.
Compare the stated facts, your English forms and the intended meaning. Revise one actual mismatch, or explain why no change is needed. This written self-review does not award correctness or certify proficiency.
