1 . I (have )                  two roommates .One of the , Sam , is always neat and clean . He ( wash )               his clothes once a week . You ( know )                 Matt, my other roommate ? He ( be )              the opposite  of Sam .For example , Matt ( change , not )                        the sheets on his bed . He ( keep )                 the same sheets week  after week . He ( wash , never )                       his clothes . He ( wear )                     the same dirty jeans everyday .Sam ‘s  side ( be , always )                  neat , and Matt’s side ( be always )               a mess . As my mother always ( say )                 , it ( take )                   all kinds of people to make a world .
