参考译文

手机实际上是一台小收音机。收音机把人的声音发送到远处的另一台收音机上。通过收音机传输的声音叫做信号。收音机的信号传输得非常快。

仅仅在几年前，手机还很大。因为它们需要大号的电池。电池的功率必须非常强大，这样才能把信号传输到远处。这是因为大多数城市只有一座供手机使用的中继站。

现在的手机小巧易用。现在的大多数城市都有许多中继站，而不是只有一座。这意味着每部手机发送的信号都不用传播很远了，这样手机就不需要大功率的电池。现在的手机使用小号电池。大城市的手机拥有量很高，所以，大城市有数百座中继站。

你知道手机有什么用途吗？是的，你可以用它做很多事。

● 你可以在几乎任何地方给你的朋友或家人打电话。

● 如果道路上发生交通事故，你可以立刻给警察打电话。

● 发送或接收电子邮件。

● 从互联网上获取信息。

● 发送并接收信息。

发送短信是使用手机的常见方法。许多人用单词的简写形式，这样短信很快就能写好并读完。你能猜出这些短信的意思吗？试着大声读出来，你听到了什么？

你好吗？再见！这很容易！明天之前我能见到你吗？真棒！
