四、Think and make up a dialogue. 班级开展了“我是英语小编剧”活动。请你想一想，尝试用含有字母组合wh的疑问词创编英语对话吧。
Words I use:

A: Shh! Talk quietly! What are you doing?
B: Oh, sorry! I'm looking for my English book. Where is it?
A: Is it under your desk?
B: No, it isn't. Who saw my book?
A: Maybe Lily did. She was cleaning the classroom just now.
B: When will she come back?
A: She'll be back in five minutes.
B: OK, thank you! I'll wait quietly.

需使用含字母组合wh的疑问词（如what, where, who, when等），结合本单元“公共场合遵守秩序、保持安静”的主题创编对话，对话要符合五年级英语词汇语法水平，做到条理清晰、表达自然。
