She is a shop assistant.Her career was clerk 这两句的意思是一样的.有些重复,另外表示具体工作不用career,这个单词主要用于职业生涯.你表述到她是个很好的售货员,那么她的好表现在哪里呢,你需要写出来.
She is a shop assistant.Her name is Mary.And she goes to work by bus everyday.As far I as know,she works very hard,and after work,she will study by herself and make dinner for her family.What a nice girl she is.We should learn from her.
