Do you know how people get their names? Let me tell you something family names in North America. People there (have) two names. Usually, their (father) last names are their last names. It is also the family name. At the beginning(起初)，people in North America only have one name. After some time, there (be) many people with the same name. It's difficult (know) who is who.
