解析：
【分析】
本题为宾语从句引导词的填空题，需结合主句动词的语义、从句的语境（如是否有疑问、是否缺成分、是否与or not搭配等）选择合适的引导词。解题思路：先判断主句动词（如sure、wonder、argue等）的用法，再分析从句的语义或成分，进而确定引导词。
【解析】
1. 主句为“Are you sure”，后接陈述事实的宾语从句，that起连接作用，无实际意义，故填that；
2. wonder意为“想知道”，后接原因时用why引导宾语从句，故填why；
3. 从句后有or not，固定搭配为whether...or not，表“是否”，故填whether；
4. 从句询问艺术展开放的时间，用when引导时间相关的宾语从句，故填when；
5. be surprised后接陈述内容的宾语从句，用that连接，故填that；
6. ask for help的对象是人，who在从句中作宾语，故填who；
7. 从句询问古桥建造的方式，用how引导方式相关的宾语从句，故填how；
8. doubt意为“怀疑”，后接是否的内容时用if引导宾语从句，故填if；
9. 从句询问放置笔记本的地点，用where引导地点相关的宾语从句，故填where；
10. 从句中缺少主语，指代事物，用what引导宾语从句，故填what。
【答案】1.that 2.why 3.whether 4.when 5.that 6.who 7.how 8.if 9.where 10.what
