I then realized she had no arms or legs, just a head, a neck and upper body, 小题3:_______   ( dress ) in a little white skirt. As the couple wheeled her up to me, I turned my head toward the girl. When I took the money from her grandparents, I looked back 小题4:________ the girl, who was giving me the most optimistic, largest smile I had ever seen. All of a sudden, her handicap was gone and all I saw was this beautiful girl, 小题5:________   smile just melted me  小题6:_______   almost instantly gave me a completely new sense of   小题7:_______   life is all about. She took me from a poor, unhappy college student and   小题8:___________   ( bring ) me into her world; a world of smiles, love and   小题9:__________  ( warm ).
