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. "
【C4】
选项 A、which
B、whom
C、who
D、what
答案C
解析 本题考查的是定语从句。句意：这七年的研究发现——每天走或者骑车至少半小时的人比那些不锻炼的人死于癌症的——要少34％。此处在从句中缺少主语，因此C为正确答案。
