DO you have your own email address? Your address has three parts. The first part is the user name. Most people choose their name or another word that means something important. Then comes the "@" sign (符号). After that is the host name (服务器名). For example, in the email address Linda@yahoo.com, "Linda" is the user name and "Yahoo.com" is the host name. "@" means "at" and should be pronounced (发音) in the same way.
