Future Forms 2: Due To, About To and Likely To

By the end: I can distinguish a schedule, an imminent action and a prediction of likelihood.

Created by , British English teacher.

I’m studying:

Try the activities, then check your answers.

Choose a short recording.

Before you start

Compare a scheduled delivery with a delivery you think will probably arrive soon.

Useful background: Will, going to and present continuous for future reference.

Due to: expected by a schedule

Be due to plus a base verb describes an event expected or scheduled to happen. Due at or due on can give an expected time. A schedule is not a guarantee that the event will happen exactly as planned.

The parcel is due to arrive tomorrow.

The session is due to start at ten.

The words due to occur in two different constructions

Expected actionThe train is due to leave.

Due describes the schedule; to leave is an infinitive naming the expected action.

Cause of a past situationThe delay was due to rain.

Due to rain means caused by rain; rain is a noun.

Look at the words that follow. An expected action uses be due + to-infinitive. A cause can use be due to + noun phrase. The shared words do not make the meanings identical.
Preserved lesson scene for I'm about to send the message. People and essential props isolated on white.
I’m about to send the message.About to describes an action on the point of happening.

About to: on the point of happening

Be about to places an action very close to starting. It is not normally used with a distant future time such as next year. It can describe an intention or an event whose beginning is imminent.

I’m about to send the message.

The film is about to begin.

Likely to: a prediction, not a timetable

Be likely to predicts a probable outcome; be unlikely to predicts that it probably will not happen. These forms do not themselves say that something has been formally scheduled. Unlikely does not mean impossible.

The discussion is likely to take an hour.

The shop is unlikely to reopen today.

Guided practice

Say or write your answer first. Compare the meaning and form; the model is one possible answer.

1. Complete a schedule: The course is due ___ on Monday. Use begin.

Compare a model and explanation

to begin

Due takes a to-infinitive in this pattern.

2. Choose an imminent-action expression for a person opening the door to leave.

Compare a model and explanation

They are about to leave.

About to presents the action as immediately approaching.

3. Rewrite a probability statement: The room will probably be busy.

Compare a model and explanation

The room is likely to be busy.

Likely to expresses predicted probability.

4. Rewrite: It probably won’t finish today.

Compare a model and explanation

It is unlikely to finish today.

Unlikely means probably not, not impossible.

5. Explain why I’m about to graduate next year is normally an awkward imminent-action description.

Compare a model and explanation

About to suggests the immediate future, while next year normally places the event much further away.

The time scale conflicts with the ordinary use being taught.

6. Distinguish due to in The train is due to leave and The delay was due to rain.

Compare a model and explanation

The first concerns a scheduled action; the second means caused by rain.

Identical words participate in different constructions.

7. Write a schedule plus a prediction: The event starts at six; you expect a queue.

Compare a model and explanation

The event is due to start at six, and there is likely to be a queue.

Do not treat the queue as a confirmed arrangement.

8. An item is due tomorrow. Has its arrival tomorrow been guaranteed? Explain.

Compare a model and explanation

No. Due gives an expected or scheduled time; actual events may change.

A timetable and a guaranteed outcome are not identical.

A short conversation

Listen first if you can, then open the transcript when useful.

Open the conversation transcript

A: The new equipment is due to arrive tomorrow. Is the room ready?

B: Almost. I’m about to move the last table.

A: Do you think installation will be quick?

B: It’s likely to take most of the morning, so the afternoon class may need another room.

Listening checks

Listen to each extract or open its transcript. These three questions have their own score.

1. Which action is imminent now?
Read the listening transcript

The workshop is due to begin at nine. The presenter is about to test the microphone now.

2. What is expected by schedule on Friday?
Read the listening transcript

The replacement part is due on Friday, but the technician thinks the repair is unlikely to be finished before Monday.

3. How should the statement be understood?
Read the listening transcript

The room is likely to be crowded, but we have no booking information yet.

The discussion is likely to take an hour.Likely to expresses a prediction rather than a fixed timetable.

Mastery quiz

Choose the best answer in each situation. Your score is out of eight.

1. Which phrase best reports a timetable?
2. You are seconds away from pressing send. Choose the ordinary description.
3. Complete: The answer is likely ___ complicated.
4. What does unlikely normally mean?
5. Which separates schedule from prediction?
6. In The delay was due to traffic, what does due to express?
7. Choose the ordinary imminent-action sentence.
8. Which interpretation is safest for The parcel is due tomorrow?

Use it in your own words

Speaking task 1

Give a fictional event update with one scheduled event, one imminent action and one prediction.

Reveal a possible response

The training session is due to begin at ten. I’m about to open the room, and the first activity is likely to take twenty minutes. We can adjust the break if necessary.

Success check: Keep the three kinds of future reference distinct.

Speaking task 2

Explain a possible delay without claiming certainty.

Reveal a possible response

The equipment is due tomorrow, but the installation is unlikely to finish before lunch. I’m about to contact the technician to check the plan.

Success check: Distinguish confirmed arrangements from your expectations.

Speaking task 3

Correct a colleague who treats likely as guaranteed and due as already completed.

Reveal a possible response

Likely means we expect an outcome, not that it is certain. Due gives an expected time, not proof of completion. We still need confirmation that the work has actually finished.

Success check: Preserve the difference between expectation, schedule and evidence.

Take it with you

I can distinguish a schedule, an imminent action and a prediction of likelihood.
