B1 grammar lesson

Future Forms: Will, Going To and Present Continuous

English has no single “future tense”. We choose a form according to the meaning: a spontaneous decision, an intention, evidence, an arrangement or a timetable.

Choose the future form from the speaker’s situation: a decision now, an earlier intention, an arrangement, or a prediction. More than one form can be grammatical when the intended meaning changes.

The essential rules

Will

Use will for decisions made now, offers, promises and predictions based mainly on opinion.

I’ll answer the phone. · I think prices will rise.

Be going to

Use going to for an intention decided before now or a prediction based on present evidence.

We’re going to repaint the kitchen. · Look at those clouds: it’s going to rain.

Present forms

Use present continuous for a personal arrangement and present simple for a fixed timetable or programme.

I’m meeting Ana at six. · The train leaves at 6:20.

A plan develops

Earlier intention: “I’m going to visit Jo.”
Confirmed arrangement: “I’m meeting Jo at six; we’ve booked a table.”
Decision now: “The buses have stopped? I’ll take a taxi.”

After future time words such as when and as soon as, normally use a present form: I’ll call when I arrive. In an evidence-based prediction, going to highlights what you can see now; will is not automatically ungrammatical.

Official schedulepresent simpleThe course starts in May.
Teacher tip: Do not look only at the time expression. Ask what produced the future idea: an opinion, evidence, a plan, an arrangement or a schedule.

Three mistakes to avoid

✕ I will meeting her tomorrow.
✓ I will meet her tomorrow.
Use the base verb after will.

Visible evidence: Look out! You’re going to fall.

Going to foregrounds what the speaker can see. Will can also appear in a warning or prediction; the choice is about the intended meaning, not an absolute ban.

✕ When I will arrive, I’ll call.
✓ When I arrive, I’ll call.
Use present simple in future time clauses.
