Men who exercise often are less likely to die from cancer than those who(1),new research published in the British Journal of Cancer revealed yesterday.
A team of scientists from the Karolinska Institute in Sweden looked(2)the effect of physical activity and cancer risk in 40,708 men(3)between 45 and 79.
The seven-year study found that men(4)walked or cycled for at least 30 minutes a day had a 34 per cent lower risk of(5)from cancer than the men who did less exercise or nothing at all.(6)the period studied,3,714 men developed cancer and 1,153 died from the disease. The researchers suggest that half an hour's walking(7)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(8)activity they were usually doing. They then scored these responses and compared the results(9)data on cancer diagnosis and death officially recorded in a central cancer registry over a seven-year period.
Lead author,Professor Alicja Wolk,said: "These results clearly show for the first time the effect that very simple and basic daily(10)such as walking or cycling has in reducing cancer death risk in middle-aged and elderly(11)"
Dr Lesley Walker,director of cancer information at Cancer Research UK,said:"This study gives us a clear indication that men who exercise are less(12)to die from cancer,and that they are more likely to(13)the disease if they get it. It's not entirely clear from this study what role exercise plays in preventing(14)in men,but we do know that a healthy lifestyle can prevent up to half of all cancers-and(15)exercise forms a key part of this."

參考答案：
1、正確答案:B
解析:本句前面提到men who exercise，與他們相比較的顯然應當是“不經常鍛鍊的男人們”，即men who don't。
2、正確答案:D
解析:look at表示“觀察.研究”。
3、正確答案:B
解析:between 45 and 79顯然指的是這些男人的年齡，因此應選aged。
4、正確答案:C
解析:修飾前面的men一詞，因此應選限制性關係代詞who。
5、正確答案:C
解析:根據上下文可以得知，經常鍛鍊的男人“死”於癌症的危險要小。
6、正確答案:A
解析:此處顯然應選表示“在……期問”之意的ng一詞。
7、正確答案:C
解析:本段的第一句出現了walked or cycled，因此此處應選or一詞。
8、正確答案:D
解析:短文的第二段曾出現過physical activity，因此此處應選physical一詞。
9、正確答案:C
解析:將一件事與另一件事進行比較，應是compare…with…。
10、正確答案:B
解析:根據上下文意即本句接下來給出的such as walking or cycling，不難推斷此處應選exercise一詞。
11、正確答案:B
解析:短文的題目以及之前一直都在談論男人運動與否與癌症的關係，此處顯然應選men。
12、正確答案:D
解析:前面多次提到，堅持經常性運動的男人死於癌症的可能性要小，possible和likely在漢語裡都可譯作“可能的”，但在英語中意思區別很大，前者側重於“存在”的客觀趨勢，後者側重於對“存在”的預期，因而可以說It is possible for them to do，而不說they are possible to do，所以應選likely。
13、正確答案:D
解析:既然堅持經常性運動的男人死於癌症的可能性要小，那麼不難推斷這種男人即使得了癌症，存活下來的可能性也應更大些。
14、正確答案:A
解析:短文全篇都在談論男人運動與患癌症的關係，此外，接下來又出現了prevent up to half of all cancers，因此此處應選cancer。
15、正確答案:C
解析:前面提到每天運動帶給男人的好處，因此此處應選regular，表示“經常性的”。
