► We canuse modal verbs for deduction – guessing if
something is true using the available information.
► The modal verb we choose shows how certain we are
about the possibility.
✔ We use must when we feel sure that something is true or it's
the only realistic possibility.
’This must be her house. I can see her car in the garage.’ **
✔ We use may, might or could to say that we think something
is possible but we're not sure.
‘He's not answering his phone. He could be in class.’ **
✔ We use can't when we feel sure that something is not
possible.
‘It can't be far now. We've been driving for hours.’ **
