y. They said weight-loss programs that award people with money—and remind them of the cash they【M1】______ stand to lose if they fail—provided with a powerful incentive to【M2】______ lose weight compared with more conventional approaches. Dr. Kevin Volpp of the University of Pennsylvania School of Medicine was looking for an effective way to treat obese, a growing problem【M3】______ that carries serious health risks. He said many weight-loss programs fail before people are being asked to make sacrifices【M4】______ now. Volpp and colleagues studied two kinds of incentive programs for weight loss. One was a lottery-based design in which participants played a lottery and were allowed to collect their winnings if they met their weight-loss target. The other was a deposit contract, in which participants invested small amount of【M5】______ their own money which they would lose at the end of the month if they succeeded to reach their goals. People in this group also got a【M6】______ bonus if they met their goal. The researchers resigned 57 obese but otherwise healthy【M7】______ people to one of these two groups or a control group, in which people were simply weighed at the end of each month. All were aimed to lose 7.26 kg by the end of four months. People in the【M8】______ incentive groups lost far more weight than that who got no pay for【M9】______ their efforts, with about half of the participants in each group meet【M10】______ their weight loss goals.

Rise in Number of Cancer Survivors

Cancer is the second leading cause of death in the United States, after heart disease. In the (51), it was often considered a death sentence. But many patients now live longer(52)of improvements in discovery and treatment.

Researchers say death(53)in the United States from all cancers combined have fallen for thirty years. Survival rates have increased for most of the top fifteen cancers in both men and women, and for cancers in(54).

The National Cancer Institute and the Centers for Disease Control and Prevention studied the number of cancer survivors. A cancer survivor is defined(55)anyone who has been found to have cancer. This would include current patients.

The study covered the period(56)1971 to 2001. The researchers found there are three(57)as many cancer survivors today as there were thirty years ago. In 1971, the United States had about three-million cancer(58). Today there are about ten-million.

The study also found that 64% of adults with cancer can expect to still be(59)in five years. Thirty years ago, the five-year survival rate was 50%. The government wants to (60)the five-year survival rate to 70% by 2010.

The risk of cancer increases with age. The report says the majority of survivors are 65 years and (61).

But it says medical improvements have also helped children with cancer live(62)longer. Researchers say 80% of children with cancer will survive at least five years after the discovery. About 75% will survive at (63)ten years.

In the 1970s, the five-year survival rate for children was about 50%. In the 1960s, most children did not survive cancer. Researchers say they(64)more improvements in cancer treatment in the future. In fact, they say traditional cancer-prevention programs are not enough anymore. They say public health programs should also aim to support the (65)numbers of cancer survivors and their families.
