Present and Past DEDUCTIONS!


This is a trailer for a new movie that is very popular with teens, and it's great to work present and past deductions.





Show your students this movie trailer and request them to make deductions using the structures below. Engage them by asking questions:

E.g
Who could they be?
Why may this be happening? 
What could have happened?



Making Present Deductions:

We use the modals
Could / may /might + infinitive to say that something is possible
Must + infinitive to say that something is certain
Can’t + infinitive to say that something is impossible
e.g: They might be friends


Making Past Deductions:

We use the modals
Must + past participle to make a logical deduction about what has happened
Could / may /might + past participle to offer possible explanations for what happened
We use can’t + past participle to say that it is impossible that something has happened
 e.g.: He could have been abducted when he was a child
