The 2nd conditional is used to express unreal situations in the present or future. Often used to express a wish.
Uses the simple past tense:-
|If I won the lottery,||I would buy a new house.|
|I would buy a new house||if I won the lottery.|
Note! We never use would, or wouldn't in the if clause.
If I were you, I wouldn't do that. = I wouldn't do that, if I were you. (I am not you - therefore the condition is unreal).
If I had more time, I would do more on my websites. = I would do more on my websites, if I had more time. (I don't have more time - therefore the condition is unreal).
