David: Later, cell phones and smartphones were invented. They are really popular now and have become life changers.
Mary: Certainly. With their help, we can send emails or use apps to talk with someone from time to time. 5) ____________
David: I can't agree more. We can't live without them.

答案： 2) A
解析：Mary提到电话是另一种改变生活的发明，选项A“它改变了我们交流的方式”符合对电话作用的描述，引出下文关于交流方式的讨论。
3) E
解析：David回应“That's right.”并提到“It was slow.”，结合上下文，这里应指电话发明前的交流方式，选项E“在电话发明之前，人们通过写信与他人联系”符合语境，且写信速度慢，与“It was slow.”呼应。
4) B
解析：电话发明后，人们在家中安装电话，选项B“人们交流变得更容易、更快了”描述了电话带来的便利，符合逻辑。
5) C
解析：Mary提到智能手机可以发邮件、用应用聊天，选项C“我们几乎可以在它们上面做所有事情”进一步说明智能手机的多功能性，总结其重要性。
