In the first image I can see some football players on the field at a stadium.  In the second picture the goalkeeper is trying to stop the ball.  In the last photo the man with the red shirt is showing a red card to send out one of the players.

comments: Il uso delle preposizioni "on, in, at" è dificile -- The use of the prepositions "on, in, at" is difficult.  Ho l'stesso problema con "da,de, di" in italiano -- I have the same problem with "da, de, di" in Italian. (Per favore corregere il mio italiano.--Please correct my Italian.)
