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. In the coming months, Betty’s tumour continued to appear. She was able to eat solid food once again. Her jawbone was regenerating. The tumour was gone.

　If Betty’s jawbone didn’t regenerate, the doctors ________ .

　　A. would rebuild her jaw

　　B. would continue the treatment

　　C. would use new medicine

　　D. could do nothing else

　If the brain should be invaded, the result would ________.

　　A. prevent her growth

　　B. reduce her weight

　　C. cause her brain damaged

　　D. affect her eyesight

　What did the doctors do two months later?

　　A. They continued their observations.

　　B. They gave up the operation on Betty.

　　C. They found out what caused Betty’s strange disease.

D. They declared that Betty’s strange disease was cured.

Cancer is feared by everyone. And there is more and more fear about cancer. Not the disease itself — there is no such thing as a high incidence rates(发病率) of cancer. Except for lung cancer, mostly caused by cigarette smoking, the incidence rates are not on the rise. However, some kinds of cancer are decreasing. But the fear of cancer is catching, and the country stands at risk of an anxiety. The earth itself is coming to seem like a huge carcinogen(致癌物). The ordinary, more or less, scientific statement that something between 80 and 90 percent of all cancers are due to things in the environment is taken to mean that none of us will be safe until the whole environment is “cleaned up.” This is not at all the meaning.

The 80-percent calculation is based on the unthinkable differences in the incidence of cancer in various societies around the world — for example, the high incidence of liver cancer in Africa and the Far East, stomach cancer in Japan, breast cancer in Western Europe and North America, and the relatively low figures for breast cancer in Japan and parts of Africa and for liver cancer in America. These data show there may be specific environmental influences, but largely based on personal life-style, which determines the incidence of various forms of cancer in different communities — that is all the data suggest. The overall incidence of cancer, counting up all the cases, is probable roughly the same everywhere.

1.According to the passage, the incidence of cancer is generally believed _____.

2.It can be inferred from the passage that the writer’s opinion about the relationship between cancer and environment is _____.

3.According to the passage, the writer seems to feel that _____.

4.Which of the following would be the best title for the passage?
