About this lesson
In this lesson you will learn how to build Third Conditional sentences with the formula "If + Past Perfect, would have + past participle". You will understand that this type of sentence describes hypothetical past events – situations completely different from what really happened. Through texts about an adventure on the beach and about Donna's unusual weekend you will practise the structure in context. You will also practise using "be able to" instead of "can/could" with the perfect infinitive, and you will be introduced to the idea of the Mixed Conditional.
