Future Continuous and Future Perfect

I can distinguish an activity in progress at a future time from completion by a future deadline.

Created by , British English teacher.

I’m studying:

Try the activities, then check your answers.

Choose a short recording.

Start with the contrast

The team will be painting at ten tomorrow. By four, they expect they will have finished the room. At ten looks inside the activity; by four sets a latest completion point in the prediction.

Read the situation transcript

The team will be painting at ten tomorrow. By four, they expect they will have finished the room. At ten looks inside the activity; by four sets a latest completion point in the prediction.

Which sentence focuses on completion rather than progress?

Compare your idea

By four, they will have finished focuses on completion by the future point.

How it works

A woman paints a partly finished wooden panel beside a fully painted matching panel.
At this time tomorrow, she’ll be painting the other panel.Picture context: the partly painted panel will still be in progress then. The future timing is supplied here.

Use will be plus an -ing form to describe expected progress at a future moment. Use will have plus a participle to look back on completion from a future point.

At often locates the moment; by means no later than in these deadline examples. The forms express the speaker’s future view, not a guarantee that the prediction will come true.

Progress: will be doing. Completion by a point: will have done.

Reference situation

At ten, we’ll be painting.

The activity is expected to be in progress then.

Contrasting viewpoint

By four, we’ll have finished.

Completion is predicted no later than four.

Hear the examples

At ten, we’ll be painting.

The activity is expected to be in progress then.

By four, we’ll have finished.

Completion is predicted no later than four.

Will you be working at noon?

This asks about expected progress.

Will they have left by six?

This asks about completion by the future point.

One mistake worth avoiding

Instead of: By Friday, I will have finish it.

Say: By Friday, I will have finished it.

Future perfect needs a past participle after will have.
