题干选择题 It can be really frustrating (使人沮丧的) for an overweight person to go to a gym and work out with a positive attitude. All one has to do is walk by almost any nice gym and notice all the healthy, sweating, “skinny” members. Sometimes they stare at those of us who are, well, zaftig. It is easy to see the judgment behind their eyes. Who wants to put up with that? Many people are self-conscious of their bodies and feel isolated when joining workout classes of while exercising, especially if they are larger than most of the others in the group. Now the fitness industry is finally paying attention. Popular gyms are catering (迎合) to overweight and weight conscious customers by dedicating areas where the “skinny” people are not allowed. There are even gyms or programs that require members to be at least 50 pounds overweight to participate. Trainers recommend functional fitness as a practical goal, rather than six-pack abs(六块腹肌). They often use text messages to stay in touch with customers. Often at these specialized gyms, the trainers are overweight themselves, or working on their own weight goals, and this can help those people with anxiety caused by poor body image. The equipment has been designed for use by larger people. Wider seats, more cushioning, no mirrors, and tinted (有色的) windows for privacy, are all important changes. Hopefully these types of gyms will successfully grow in numbers in the future. The idea is a very simple and potentially popular one. If it helps those of us who are bigger exercise more and improve our fitness level, it's a step in the right direction. 1.

Wider seats, more cushioning, no mirrors, and tinted (有色的) windows for privacy, are all important changes.即健身设备特意加大号，不放镜子，用有色窗户保护隐私等。显然C选项说在墙上有大镜子是不对的。故C是正确答案。 5. 【答案】C 【考点】主旨题【详解】A选项是说，通过锻炼提高妇女的自信。B选项是说，传统的健身业正在失去它的顾客。C选项是说，为过度肥胖的人群专门设计的健身房。而通篇的关键词是overweight和gym, 故C是正确答案。人文英语4
