Second and Third conditional

Second and Third conditional

1. We make the third conditional by using the past perfect after 'if' and then 'would have' and the past participle in the second part of the sentence: if + past perfect, ...would + have + past participle

2. It talks about the past. It's used to describe a situation that didn't happen, and to imagine the result of this situation. Ex: If she had studied, she would have passed the exam (but, really we know she didn't study and so she didn't pass)

3. The second conditional uses the past simple after if, then 'would' and the infinitive: if + past simple, ...would + infinitive

4. We can use it to talk about things in the future that are probably not going to be true. Maybe I'm imagining some dream for example. If I won the lottery, I would buy a big house.(I probably won't win the lottery)

5. We can use it to talk about something in the present which is impossible, because it's not true. Ex: If I were you, I wouldn't go out with that man.
