Second Conditional

The Second conditional is used to talk about the unreal present and future.

Present: If I were the President, I’d know lots of important people.

Future: If I were the President, I’d ban smoking.

If clause, Result clause
If past tense, Would + Bare infinitive
If  I were the president, I’d ban smoking.

The structure can be reversed. In this case, do not use a comma.

Result clause If clause.
Would + bare infinitive If past tense
I’d ban smoking if I were the president.

When

The Second Conditional talks about unreal situations, we can only use ‘If’. We cannot use ‘When’.

I would have bought that computer when it had been cheaper. Not Correct

I would have bought that computer if it had been cheaper. Correct

Alternatives to would

We can substitute would with the modal verbs: could, might or should.
