Students will be able to
- use the third conditional in the affirmative, negative, and interrogative forms to talk about situations and events in the past that did not happen,
- form the third conditional using a clause with “if + past perfect” to talk about the condition and a clause with “would + have + past participle” to talk about the result (e.g., If I had studied for the exam, I might have passed it),
- understand that the if clause (if + past perfect) can be the first or second clause (e.g., If you had listened, you would have known the answer/You would have known the answer if you had listened),
- understand that when the if clause is first, a comma is used before the second clause, but when the if clause is second, a comma is not used (e.g., If you had come to my house, I would have made you a meal/I would have made you a meal if you had come to my house),
- understand that might or might not can be used instead of would to show probability,
- understand that could can be used instead of would to show ability and possibility,
- understand that could not can be used instead of would not to show inability.
