We can infer from the first two paragraphs that__________.

【定位】第一段第一句话“It Call be really frustrating for all overweight person to go to a gym and work out with a positive attitude．”和第二段第一句话“Many people are self-con-scious of their bodies and feel isolated when joining workout classes or while exercising，espe-cially if they are larger than most of the others in the group．”。
【答案详解】综合分析题。题干问的是“从第一段和第二段我们可以得出什么结论?”根据两个定位句，可知“体型庞大的人去健身房会有挫折感和不合群的感觉”，即选项B。A项和D项文中没有提及，C项与文中第二段最后一句的“瘦子免进的区域”相矛盾。故选B。
