【分析】这道题是用动词的正确形式完成对话，核心考点是一般过去时的运用。对话整体是回忆过去参加俱乐部博览会的经历，所有动作都发生在过去，需用一般过去时。解题思路：1. 先根据语境判断时态为一般过去时；2. 区分句式：疑问句要借助助动词did，后面动词用原形，陈述句用动词过去式；3. 注意动词过去式的规则变化和不规则变化。
【解析】1. 特殊疑问句，一般过去时需借助助动词did，故填did；2. 助动词did后接动词原形，故填see；3. 描述过去的动作，用visit的过去式visited；4. 过去的动作，show的过去式为showed；5. 过去的动作，launch的过去式为launched；6. 一般过去时的一般疑问句，句首用助动词Did（首字母大写）；7. 助动词Did后接动词原形，故填catch；8. 过去的动作，fly的过去式为flew；9. 过去的动作，explain的过去式为explained；10. let的过去式与原形一致，仍为let；11. 过去的动作，see的过去式为saw；12. 过去的动作，want的过去式为wanted；13. 描述过去的经历，have的过去式为had。
