If you invite me to your party I would have fun.
if it doesn't rain soon I would go out with my friends.
if I had an iPad I would be the happiest boy/girl in the world.
even if I am tired I am still able to do my exercises.
unless you have a photographic memory I can't remember all these people.
if you look under the table you will see your cat over there 
if I won a lottery I would buy a lot of gadgets for myself
even if I am supposed to be working by myself I can' t afford it
