The pattern

Past tense after if, would in the result:

If I knew the answer, I would tell you. — I do not know it.

Nothing here is about the past. The past tense is doing something else: it marks the situation as not real.

Unreal now, or unlikely later

Two readings, and both are standard:

Compare the first conditional, which treats the condition as a genuine prospect: If I win, I will buy a boat.

if I were you

The standard way to give advice in English:

If I were you, I’d say nothing.

Were is used with every subject in this pattern, including I, he and she. In casual speech you will hear if I was, but were is the form that tests expect and the fixed phrase always takes it.

could and might

Would can be replaced to change the meaning slightly:

Polite requests

The second conditional softens a request by pretending it is hypothetical:

It would be helpful if you could send it today.

Nothing unreal is intended. The grammar is doing manners.

Examples

Taken from the 450 sentences in this drill. The answer is highlighted.

Mistakes to avoid

Wrong: If I would have time, I would help. correct: If I had time, I would help.

Would never appears in the if-clause.

Wrong: If I was you, I'd wait. correct: If I were you, I'd wait.

The fixed phrase takes were, and formal English uses were for every subject here.

Wrong: If she studied harder, she will pass. correct: If she studied harder, she would pass.

A second conditional takes would, not will.
