　　From the very beginning, Martin felt that he was bound up with（与……紧紧地在一起）his lovely little patient. One day, following some tests , Betty gave the doctor a big hug（拥抱）.

　　A few months later the doctor removed not only the tumour（肿瘤）, but also the entire lower left side of Betty’s gum（牙龈）and jawbone. Because Betty was so young, Martin was hopeful that her jawbone might regenerate.

　　Within three months, Betty’s tumour grew as large as an orange, changing the natural appearance of the left side of her small, delicate （ =" thin;" not strong）face. Soon she couldn’t even close her mouth, and as her eating problems worsened, Betty ‘s weight dropped from 20 kilos to 15. Martin knew from experience that it might invade the brain.

　　The only other possibility was thorough radiation therapy （放射疗法）. Night after night, Betty's father gave her injection, but the tumour remained as big as ever. Then one evening. Morgan noticed that the tumour had begun to change. It was actually becoming smaller! For two months her tumour appeared to be going away for ever.
