3. A
4. D
5. C
(1) 细节理解题。根据六个月前他是more than 202 pounds(91kg),现在是He weighs 147 pounds(67kg),可知至少减了202-147=55磅。故选C。
(2) 细节理解题，根据“One day, I was surprised to find that I weighed about 200 pounds,”Rocha says.“I thought I had to do something.”可知他发现自己的体重太重了，所以想通过跑步来减肥。A答案错误，文章说“No kid likes running,” he says.“I don't want to do it either可知他并不喜欢跑步。故选B。
(3) 细节理解题。根据他的教练讲的话It's surprising to see him lose the pounds so quickly,可知他吃惊的是罗查体重的快速减少，故选A。
(4) 排序题，考查时间的先后。根据文章，首选他是做sit-ups and push-ups(俯卧撑)，接着是started jogging(慢跑)然后是joined a boxing club(加入拳击俱乐部)，再是在俱乐部练习boxes for about three hours,最后体重快速减少的，故选D。
(5) 主旨大意题。根据罗查减肥的经历告诉我们任何事情都有可能。A与B只是文章的一个方面，不能全面概况全文，选C。
