解答 CAB
21  C   细节题． 根据文章第二三四 段的第一句By keeping physically active，you're making sure that your joints （关节） and body organs （器官） are kept in good working order．锻炼可以让关节和器官处于好的状态； If you're under 18，you should try to do a total of 60 minutes of physical activity every day．如果你不到18岁，你每天要进行60分钟的锻炼； Getting fit isn't all about gyms-some forms of exercise don't cost you any money，and most forms can easily be used in your busy lifestyle without having to find some special time in your day． 可知保持健康并不意味着在健身房，一些形式的锻炼不需要任何成本；可知文章并没有提及在什么时间进行什么体育活动，故选C．
22  A   细节题． 根据文章第四 段Getting fit isn't all about gyms-some forms of exercise don't cost you any money，and most forms can easily be used in your busy lifestyle without having to find some special time in your day 可知保持健康并不意味着在健身房，一些形式的锻炼不需要任何成本，很多锻炼可以在你繁忙的生活中进行，因此第四段的段落大意是在健身房之外的锻炼方式．故选A．
23  B   细节题． 根据文章最后一段Playing team sports like football，or basketball is great exercise，and it is often more enjoyable because you're playing with a group of friends．可知踢足球不仅仅能锻炼身体，而且还可以和朋友们玩得开心，故选B．
