To talk about an (1) _________________ (imaginary/actual) situation, we use unreal conditionals.
We form unreal conditionals in different ways.
Present: If…were/did…,…would/should/could do…
Past: If…(2) _________________…, … would/should/could have done…
(3) _____________: If…were/did/should do/were to do…,…would/should/could do…
We use mixed conditionals when the time of the main clause is different from that of the if-clause.
