邮件的早期历史

The History of the Early Mail

现在你和你的亲朋好友取得联系非常容易。你有多种选择，你可以写信、打电话或发电子邮件给他们。而且你的信、电话、电子邮件都会很快到达你的朋友那里。但是在早期，没人知道他们寄出的信何时何地才能到收信人手里。

Now it is very easy for you to get in touch with your friends or relatives. You have many choices. You can write to them, call them or send an e-mail to them. And your letters, telephone calls or e-mails will get to your friends or relatives very quickly. But in early days, no one could be sure when or where the mail would arrive.
