Smartphone
“Smartphone” 是现代高频名词，指可安装应用、联网、多媒体处理的手机。它区别于仅有基础通话功能的 traditional phone。
- “Most people check their smartphone within minutes of waking up.” (大多数人醒来几分钟内就会看手机。)
- “This smartphone has an excellent camera for night photos.” (这款智能手机夜拍效果很好。)
- “He uses his smartphone to manage work and study schedules.” (他用智能手机管理工作和学习日程。)
该词由 smart（智能的）与 phone（电话）组成，体现了手机从通话工具向多功能设备的演化。
“Smartphone” 属于复合词构词，核心是两个常见基础词组合。
在英语世界，smartphone 不只是设备词，也与数字生活、社交媒体和移动办公文化密切相关。
- 固定搭配: “smartphone app” (手机应用), “smartphone user” (智能手机用户)
- 相关词: “phone” (电话), “tablet” (平板电脑)
把它拆开记：smart（聪明、智能）+ phone（电话）= 智能手机。
“When her laptop crashed, Nina finished the whole presentation on her smartphone before the meeting.” (当笔记本崩溃时，妮娜在开会前用手机完成了整份演示文稿。)
