【分析】
本题为任务型阅读中的七选五题型，解题思路为：先通读全文把握主旨（锻炼的重要性），再逐题分析上下文逻辑关系：31题需承上启下，连接“不想锻炼”与“锻炼的原因”；32题衔接“锻炼对身体好”与“身体变化的表现”；33题总起“锻炼对大脑的作用”段落；34题对应“大脑产生的化学物的作用”；35题为开放题，结合自身情况回答且不超15词即可。
【解析】
31. 前文提到人们不想锻炼的情况，后文引出锻炼的理由，E项“但我们应该尽量每天锻炼”承上启下，符合逻辑；
32. 前文说明锻炼对身体有益，后文阐述锻炼让身体更强壮、维持健康体重，D项“当我们锻炼时，我们的身体会变化”衔接上下文；
33. 后文围绕锻炼对大脑的作用展开，C项“锻炼对我们的大脑也很好”总起该段；
34. 前文提到锻炼时大脑产生特殊化学物，B项“这些能让我们感觉更好”对应化学物的作用；
35. 为开放题，结合自身实际，符合字数要求即可，示例答案为Yes. Because it is good for my health and makes me happy.
【答案】
31.E 32.D 33.C 34.B 35. Yes. Because it is good for my health and makes me happy.
