It's a beautiful day, isn't it? 
Martha is angry, isn't she? 
I'm late, aren't I? 
You can play the violin, can't you? 
You went to Costa Rica in 1990, didn't you? 
Carol is fat, is she?
Mark is peaceful, isn't he?
The are uglyes, aren't they?
Toda isn't raining, is it?
She have a beautiful smile, haven't she?
