Grade 5 Grammar Lesson 11 The conditional
The second conditional type is used to talk about impossible or possible but unlikely situations. The second type has a past tense verb in the if clause and would +verb in the main clause.
The third conditional type is used to talk about past events that are no longer possible to be fulfilled. The third type has past perfect tense (had + past participle) in the if clause (and would/could/ might + have + past participle), in the main clause.
