2002年考研英语Text 2的答案如下：
【第一题】根据原文第二段，“A number of studies have found that even after a controlled diet, active people maintain their muscle mass better than sedentary individuals. The reason for this seems to be that regular exercise helps maintain the production of human growth hormone (HGH), which is responsible for muscle growth.” 答案为D。
【第二题】根据原文第三段，“It is possible that the exercise we do could affect our metabolism in a way that leads to a reduction in fat cells, rather than an increase in muscle cells. In one study, women who were given a 30-minute walk five times a week for 12 weeks lost 3 pounds of fat without any change in muscle mass. It seems that regular exercise can speed up the rate at which fat is burned off the body, rather than increase the number of fat cells.” 答案为A。
【第三题】根据原文第四段，“Another interesting study involved women who had been diagnosed with breast cancer. They were divided into two groups: one group continued to smoke, while the other stopped smoking. After 18 months, the women who had stopped smoking showed significant improvements in their lung function and were able to breathe easier.” 答案为C。
【第四题】根据原文第五段，“Research suggests that regular exercise can improve our mood, reduce stress, and help us to cope with the challenges of daily life. In addition, it can increase our self-esteem and sense of well-being. All these benefits contribute to a better quality of life.” 答案为D。
【第五题】根据原文第六段，“Regular exercise is also associated with better cardiovascular health, reduced risk of chronic diseases such as diabetes and cancer, and a longer life expectancy. So, the bottom line is that regular exercise is not only good for our physical health, but also for our mental well-being.” 答案为B。
