Upper Intermediate students practiced ‘modals of deduction’ by doing a ‘Murder Mystery’. They had to read clues and, using the past modals of deduction, find out ‘who did it’. They used mind maps and notes to get the answers. Were they right?
Thomas couldn’t have afforded to buy a house.
Caroline might not have argued with her Father.
Lady Mary mustn’t have been the murderer.
Nope! No-one guessed the answer!
