问题     Men who exercise often are less likely to die from cancer than those who【C1】______, new research published in the British Journal of Cancer revealed yesterday.
    A team of scientists from the Karolinska Institute in Sweden looked【C2】______the effect of physical activity and cancer risk in 40,708 men aged【C3】______45 and 79.
    The seven-year study found that men【C4】______walked or cycled for at least 30 minutes a day had a 34 per cent lower【C5】______of dying from cancer than the men who did less exercise or nothing at all. 【C6】______the period studied, 3,714 men developed cancer and 1,153 died from the disease. The researchers suggest that half an hour’s walking【C7】______cycling a day increased survival among these men by 33 per cent.
    The researchers surveyed men from two counties in central Sweden about their lifestyle and the amount of【C8】______activity they were usually doing. They then scored these responses and compared the results with data on cancer diagnosis and death officially recorded in a central cancer registry (登记簿) over a seven-year【C9】______. Lead author, Professor Alicja Wolk, said: "These results clearly show for the first time the effect that very simple and basic daily【C10】______such as walking or cycling has in reducing cancer death risk in middle-aged and elderly_men. "
【C1】
选项 A、didn’t
B、don’t
C、won’t
D、can’t
答案B
解析 本题考查的是词汇。句意：那些经常锻炼的人比那些经常——死于癌症的几率要小。此处是对比的含义，经常锻炼和不经常锻炼的人，此处exercise对应的原形是do，因此此处是do的否定式，don’t，故选B。
