Lack of exercise is considered a risk factor for cancer. There is considerable evidence that inactivity is connected with increased risk for lung cancer, breast cancer, etc.
In the Aerobics Center Longitudinal Study, more than 32,000 people (25,000 men and 7,000 women) were given a preventive medical examination that included a machine exercise test to measure physical fitness. They were given a physical fitness score, with one being the lowest and five being the highest fitness level. Then these people were followed for an average of 8 years. During this time, 179 men and 44 women died of cancer.
Data from the Aerobics Center Longitudinal Study show people have lower rates of cancer with higher levels of physical fitness. Studies from the Cooper Institute for Aerobics Research in Dallas suggest that men with high fitness levels are less likely to die of cancer.
The Aerobics Center Longitudinal Study also found that fitness level was more important than weight in predicting longevity (长寿). While results showed that fitness and normal weight are the ideal combination, researchers found that men who were fat but performed well in the machine performance had just a slightly increased all-cause death rate, including cancer, compared to the more slim men. The fat, but fit, men particularly lived longer than the slim, but flabby (肌肉松弛的), men.
These statistics called for a warning to the overweight: The first health goal for the overweight should be to become as fit as possible at their current weight.

解析试题分析：本文叙述的是一项健康调查报告，讲述的是体育锻炼对癌症的影响以及锻炼和身体健康之间的关系。
【小题1】A 主旨大意题。根据文章主题段第一段Lack of exercise is considered a risk factor for cancer. There is considerable evidence that inactivity is connected with increased risk for lung cancer, breast cancer, etc.可知本文讲述的是锻炼对减少患癌症的可能性有很大的影响。故A正确。
【小题2】B 段落大意题。在文章第二段中In the Aerobics Center Longitudinal Study, more than 32,000 people (25,000 men and 7,000 women) were given a preventive medical examination that included a machine exercise test to measure physical fitness. They were given a physical fitness score, with one being the lowest and five being the highest fitness level.可知这个研究正是关于锻炼和癌症之间的联系，故B正确。
【小题3】C 推理题。根据文章倒数第3行The fat, but fit, men particularly lived longer than the slim, but flabby (肌肉松弛的), men.可知C项说法是错误的，最重要的不是保持身材苗条，而是身体健康。
【小题4】A 细节题。根据文章最后2行These statistics called for a warning to the overweight: The first health goal for the overweight should be to become as fit as possible at their current weight.可知最主要的是提高健康的水平，故A正确。
