【分析】
做这类补全对话题，首先要通读完整对话，明确对话主题是围绕各类自然奇观展开的问答，再结合每个空的前后文提示反推所需填写的句子：
1. 第一空前文提到B对撒哈拉沙漠很好奇，后文A以Sure开头，介绍了撒哈拉的面积和地位，说明此处是B向A提出请求，询问对方能否介绍撒哈拉沙漠的相关信息，用表示请求的一般疑问句即可。
2. 第二空后文A的回答明确指出海洋的最深点在马里亚纳海沟，前文B也提到自己记得海洋里有个很深的地方，说明此处B是在询问海洋的最深点在哪里，用对应的特殊疑问句即可。
3. 第三空前文B提到深海的盲动物反而能很好地“看”东西，后文A解释它们靠回声或者其他感官实现“看”的能力，说明此处B是在询问这些动物是怎么做到“看”的，用how引导的特殊疑问句提问即可。
4. 第四空前文B提出疑问“珠穆朗玛峰是不是还在不断长高”，后文A补充说明地球内部的力量一直在把它往上推，说明此处需要给出肯定回答。
5. 第五空前文B向A表达了感谢，此处填入回应感谢的常用交际用语即可。
【解析】
1. 结合上下文逻辑，B对撒哈拉沙漠好奇，向对方请求介绍相关信息，可填入符合请求语义的正确表达，比如Could you tell me something about it / Do you know anything about it等。
2. 根据后文A回答海洋最深点的具体位置，可知此处是对海洋最深点的位置提问，可填入Where is the deepest point in the ocean等符合语义的正确句子。
3. 根据后文A解释深海盲动物实现“看”的原理，可知此处是询问它们实现“看”的方式，可填入How do they "see" / How can they do that等符合语义的正确句子。
4. 结合后文地壳抬升的补充说明，此处是对一般疑问句作出肯定回答，可填入Yes / Yes, it is等正确的肯定表达。
5. 前文对方表达了感谢，此处填入回应感谢的常用交际语即可，比如You're welcome / My pleasure等。
