Can-Do Task: Speculating About a Mystery
Task: speculate about an unexplained situation using a range of modal and speculative language.
Notice
- Example: The lights were on all night, so someone must have been working late. They could have forgotten to turn them off, but I dare say it was intentional — they’re bound to have an early deadline.
Rule
Your task: Write 5–7 sentences speculating about a mystery or unexplained situation (real or invented). Use at least four structures from this module: modal perfect continuous, would/dare say/should think, and bound to/on the verge of/likely to.
Practice
- Planning line: what mystery or situation will you speculate about?
Answer: Personal answer. - Draft one sentence using the modal perfect continuous.
Answer: Personal answer, e.g. ‘They must have been planning this for weeks.’
