Explanation:
Conditional sentences are sentences used to introduce a condition that needs to be fulfilled in order for something to happen. They consist of two clauses - the main clause and the if-clause, which introduces the condition. There are four types of conditionals: zero, first, second, and third conditionals.
The second conditional is most often used to talk about things in the future that are probably not going to happen or things in the present that are impossible. In the if-clause, the verb should be in the past simple tense, and in the main clause, it should be in the infinitive form and preceded by <em>would</em>. That means that its formula is the following:
- If + past simple, ...would + infinitive.
