Are we doctors? [не Do we be doctors?/Do we are doctors?]
Is he a doctor? [не Does he be a doctor?/Does he is a doctor?]

probably everyone has their own favorite sport, some people have volleyball, some people have football, but I have hand ball. This is such an interesting sport, where the game begins by entering the ball from the middle of the field. Players can play with all parts of the body except the legs. This is so interesting, because people play for fun without thinking about anything. If you try to play handball, then you will not be able to break away from training and competitions!
