【分析】
这道题需根据句子前后分句的逻辑关系（因果、并列、转折）选择合适的连词。解题时，先逐句分析每个空前后两部分的逻辑联系：第一句中“Duoduo难过”的原因是“Tutu和新朋友玩”，需用表原因的连词；第二句中“走开”和“不加入”是并列动作，需用表并列的连词；第三句中“有新朋友”和“仍喜欢多多”是转折关系，需用表转折的连词；第四句中“坐在多多旁边”和“说加入我们”是并列动作，需用并列连词；第五句中“仍难过”和“图图告诉他那句话”是转折关系，需用转折连词；第六句中“有三个朋友”和“开心”是顺承结果，需用并列连词。
【解析】
1. 前半句“Duoduo is sad”是结果，后半句“Tutu is playing with new friends”是原因，填because；
2. “walks away”和“doesn't join them”是并列动作，填and；
3. “has new friends”和“still likes Duoduo”是转折关系，填but；
4. “sits next to Duoduo”和“says, “Join us!””是并列动作，填and；
5. “still sad”和“Tutu tells him...”是转折关系，填but；

首先明确三个核心连词的用法：but表转折关系（前后内容相反/相对），and表并列/顺承关系（前后内容相关，无转折/因果），because表因果关系（前果后因或前因后果）。再逐个分析句子逻辑：
1. 句子前后是顺承的并列关系，选对应连词；
2. 句子是前果后因的关系，选表原因的连词；
3. Why提问需用Because回答，直接对应；
4. 句子前后是转折关系，选表转折的连词。
【解析】
1. 前半句“我喜欢和朋友玩”与后半句“我们一起总是很开心”是顺承并列关系，需用表并列的连词。A选项but表转折，C选项because表原因，均不符合，故选B；
2. “Lily开心”的原因是“朋友和她分享午餐”，需用表原因的连词。A选项but表转折，B选项and表并列，均不符合，故选C；
3. 问句由Why引导询问原因，回答原因需用Because。A选项But表转折，B选项And表并列，均不符合，故选C；
4. 前半句“跳舞犯小错”与后半句“朋友仍鼓掌”是转折关系，需用表转折的连词。B选项and表并列，C选项because表原因，均不符合，故选A；
