加姓

用户是否可以注册，以创建自己的用户名，或者名称基于用户的电子邮件地址或其他可能已知的构造（名的第一个字母加上姓）？

Can users register to create their own user names , or are the names based on users'e-mail addresses or some other potentially well-known construct ( first letter of first name plus last name )?

不过大部份的正式场合里，人们会采用适当的称谓。例如：先生、女士、博士、教授再加上姓来称呼人。

But in most formal situations , people use an appropriate title-such as Mr. ( Mister ) , Ms. ( " Miz " ) , Dr. ( doctor ) or Prof. ( professor ) - with a person 's last name .

对不认识的人要称呼他们的姓：用他们的头衔（先生、女士、博士等）加上他们的姓。

Use last names with people you do not know : Address people using their title ( Mr , Ms , Dr ) and their last names .
