【分析】
解题思路：补全对话需结合上下文语境，根据每空前后的语句逻辑匹配对应选项。
1. 第一空后孩子们回答“Yes, of course.”，说明前一句是一般疑问句，选项中只有D是一般疑问句，询问是否想要帮忙，符合语境。
2. 第二空前Sally说想当排队管理员，对应选项C中“帮大家排队”的内容，逻辑一致。
3. 第三空前Ben说想在午餐时间帮忙，选项B中“给别人分发食物”是午餐时的工作，匹配语境。
4. 第四空后Peter说想整理书籍，选项E中“想成为图书助手”与整理书籍的内容对应，符合逻辑。
5. 第五空后Jenny回答了自己想做的事，说明前一句是询问她想做什么，选项A的问句正好对应。
【解析】
(1) 根据答语“Yes, of course.”可知，此处是一般疑问句，选项D“Do you want to help out?”符合语境，故填D。
(2) 根据前一句“I want to be a line leader.”，选项C“I want to help everyone stand in line.”是排队管理员的职责，逻辑匹配，故填C。
(3) 根据前一句“I want to help at lunch time.”，选项B“I want to hand out food to others.”是午餐时的工作内容，符合语境，故填B。
(4) 根据后一句“I want to put away books.”，选项E“I want to be a book helper.”与整理书籍的工作对应，故填E。
(5) 根据答语“I love flowers. I want to be a plant helper...”可知，此处是询问对方想做什么，选项A“What do you want to do?”符合语境，故填A。
【答案】
(1) D (2) C (3) B (4) E (5) A
