maria:kangkang,what does your mother do?kangkan g:she is a teacher. jane:and your father?kangkang:he is a doctor.michael,what do your parents do? michael:they are office workers.
主要就是关于职业的问法及回答,即---What do sb.do?---sb.be+职业 其中助动词do和系动词be 要随主语人称进行数的变化.这里问的是康康的妈妈mother,爸爸father和马歇尔的父母parents,前两个是第三人称单数形式,因而对应的助动词为does和系动词is,而父母为复数,因而对应的是助动词do和系动词are.
