【分析】首先通读对话，明确对话围绕Danny父亲发明的机器展开，需根据答句内容推导对应问句或答句，保证对话逻辑连贯：21题答句说明发明者，需提问发明者；22题答句为时间，需提问发明时间；23题答句为用途，需提问用途；24题答句说明运作方式，需提问运作方式；25题是请求尝试，需给出同意的答句。
【解析】21. 根据答句“It was invented by my father.”，可知问句询问“谁发明的”，故填Who invented it?（合理即可）；22. 根据答句“Yesterday morning.”（时间），问句询问“什么时候发明的”，故填When was it invented?（合理即可）；23. 根据答句“It is used for riding or flying.”（用途），问句询问“它用来做什么”，故填What's it used for?（合理即可）；24. 根据答句说明的操作逻辑，问句询问“它是怎么运作的”，故填How does it work?（合理即可）；25. 根据问句“May I have a try?”（请求尝试），答句需表示同意，故填Of course.（合理即可）
【答案】21. Who invented it? /Who invented the machine? /...；22. When was it invented? /...；23. What's it used for? /...；24. How does it work? /...；25. Of course. /Yes. /OK. /Sure. /...
