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.

　　参考答案：

1、正确答案:B

解析:本句前面提到men who exercise，与他们相比较的显然应当是“不经常锻炼的男人们”，即men who don't。

2、正确答案:D

解析:look at表示“观察.研究”。

3、正确答案:B

解析:between 45 and 79显然指的是这些男人的年龄，因此应选aged。

4、正确答案:C

解析:修饰前面的men一词，因此应选限制性关系代词who。

5、正确答案:C

解析:根据上下文可以得知，经常锻炼的男人“死”于癌症的危险要小。

6、正确答案:A

解析:此处显然应选表示“在……期问”之意的ng一词。

7、正确答案:C

解析:本段的第一句出现了walked or cycled，因此此处应选or一词。

8、正确答案:D

解析:短文的第二段曾出现过physical activity，因此此处应选physical一词。

9、正确答案:C

解析:将一件事与另一件事进行比较，应是compare…with…。

10、正确答案:B

解析:根据上下文意即本句接下来给出的such as walking or cycling，不难推断此处应选exercise一词。

11、正确答案:B

解析:短文的题目以及之前一直都在谈论男人运动与否与癌症的关系，此处显然应选men。

12、正确答案:D

解析:前面多次提到，坚持经常性运动的男人死于癌症的可能性要小，possible和likely在汉语里都可译作“可能的”，但在英语中意思区别很大，前者侧重于“存在”的客观趋势，后者侧重于对“存在”的预期，因而可以说It is possible for them to do，而不说they are possible to do，所以应选likely。

13、正确答案:D

解析:既然坚持经常性运动的男人死于癌症的可能性要小，那么不难推断这种男人即使得了癌症，存活下来的可能性也应更大些。

14、正确答案:A

解析:短文全篇都在谈论男人运动与患癌症的关系，此外，接下来又出现了prevent up to half of all cancers，因此此处应选cancer。

15、正确答案:C

解析:前面提到每天运动带给男人的好处，因此此处应选regular，表示“经常性的”。
