e-mail的定义
e-mail的英文解释是a message that is sent from one person to another using the computer system,意即一个人通过计算机系统发送给另外一个人信息。在当今商务领域，使用e-mail已经非常普及。
e-mail的格式
先看下面几个例子，熟悉一下e-mail的格式，并注意e-mail在语言上的特点。
例1.
例2.
to: mikezhang@abc.com from: lilylin@abc.com cc:hi mike!we'll meet at 2pm tomorrow afternoon to discuss the pricing policy for our new product. could you come and join us? please let me know asap.
例3.
to: green@microhard.com from: phillips@microhard.com cc:hi green! please make suitbale hotel reservation for mr. and mrs.smith from evening of july 18 through morning of july 23.
reservation [rezə'veɪʃ(ə)n]n. 预约，预订；保留
从上面的实例中可以看出e-mail的格式主要包括4项：
to：即这个e-mail发给谁，通常是接受者的电子邮件信箱。
from：即这个e-mail是谁发的，通常是发送者的电子邮件信箱。
cc:carbon copy 的缩写，愿意是用复写纸预写副本，在e-mail 中为“抄送”之意，即可同事把此邮件发给其他的人，有时也可写成copy to：。
subject：即主题，也就是这封e-mail的主要内容是什么。
另外从语言上看，这三封e-mail在语气上有很强的口语化的痕迹，这点与note有相同之处。但e-mail的语气的正式程序也要视发送者和接收者之间的关系。某些情况下如果用e-mail的方式发送信件，那么行文就应该是正式的。
请看下面这例子：
