【分析】
这是英语阅读理解的细节类题目，解题思路为：先明确每个问题的核心，再回到原文对应板块（Time、Groups、Notice）定位关键信息，将选项与原文内容逐一对比，选出正确答案。
【解析】
31. 题目询问志愿者的工作时长，定位原文Time板块：“Work as a volunteer from 8:30 a.m. to 11:30 a.m.”，计算可得工作时长为11:30 - 8:30 = 3小时，对应选项D。
32. 题目询问加入Group4不会做的事，定位原文Groups板块：Group4的任务是“Prepare some food to feed the homeless pets and call Pet Centre”，选项A“Talk with old people”是Group3的任务，因此选A。
33. 题目要求选出正确陈述，逐一核对选项：A选项“Sunday”与原文Notice中“every Saturday”不符；B选项“free lunch”与原文“get a shirt for free”不符；C选项“call Susan”与原文“email me at Susan@mail.com”不符；D选项“come back at 12:00 a.m.”与原文“Come back to our community at 12:00 a.m.”完全一致，因此选D。
