If I do ... and If I did ...

If you took more exercise, (feel better).

I'd be very angry if (somebody broke into my house).

If I didn't go to work tomorrow, (I / have a much nicer day than usual).

Would you go to the party if (you / invite)?

If you bought some new clothes, (you / feel much better).

Would you mind if (I / not / go out with you this evening)?
