Question

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 (長壽). 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.

67. 1.The text mainly talks about________.

A．the effect of exercise on reducing chances of cancer

B．how to lose weight effectively

A．The study on the life of the overweight.

B．The study on the relationship between taking exercise and cancer.

D．The study on the effects of machine exercise.

69. 3.Which of the following is NOT true according to Paragraph 4?

A．Fitness levels have more effects than weight on people’s longevity.

B．A man who is fit and has normal weight is most likely to live longer.

C．Slim men are more likely to live longer.

D．Fat people who like exercising are also likely to live longer.

【答案】

1.A

2.B

3.C

4.A

【解析】

試題分析：本文敘述的是一項健康調(diào)查報告，講述的是體育鍛煉對癌癥的影響以及鍛煉和身體健康之間的關(guān)系。

1.A 主旨大意題。根據(jù)文章主題段第一段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.可知本文講述的是鍛煉對減少患癌癥的可能性有很大的影響。故A正確。

2.B 段落大意題。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.可知這個研究正是關(guān)于鍛煉和癌癥之間的聯(lián)系，故B正確。

3.C 推理題。根據(jù)文章倒數(shù)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項說法是錯誤的，最重要的不是保持身材苗條，而是身體健康。

4.A 細節(jié)題。根據(jù)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正確。
