My grandfather is sixty_five old,he is a doctor.My grandmother is sixty old.I have a little sister,she is an one_month_old baby,she is my uncle''s daughter.my cousin is twelve old big boy,he is my aunt''s son.We get on very well.名师点评：在这篇作文里，小作者向我们介绍了他的主要亲戚，有当医生的祖父，祖母，堂妹，表弟等人。总体来说，比上一篇文章有进步了！“she is an one_month_old baby”改为“she is a one_month_old baby”。one前面要用不定冠词a。继续努力！（学乐中国特聘教师：邹紫老师）2009-8-23 12:00:00
