If I were you I would never let me go
If you come I'll give you a present
If you call me I'll tell you urgant information
If you know the problem you'll understand me
If I knew her address I would call her
If you give me a pen I'll write second Essay
If you take off the coat I'll put somewhere
If I found $100 I would keep it
If we didn't go to the party they would be angry
