      为引导广大中小学生及其家庭成员积极投身我市创建卫生城市当中，努力在全社会形成“人人参与、家家行动、你追我赶、争当先进”的创卫氛围。5月24日上午，赤坎区教育局、关工委、妇委、总工会、团区委等单位联合举办以“小手牵大手，争创文明户”为主题的“创卫”演讲比赛。
     这次演讲比赛饶有新意，比赛以家庭为组合，参赛选手为一名学生及一名家庭成员。演讲过程中，选手们都紧紧围绕着“创卫”的话题，从不同的角度，并结合自身的经历进行演讲。
      通过举办此次演讲比赛活动，“创卫”的理念带进了家庭，带进了社区，带动了全社会共同参与。

    It's Sunday morning. There are many people in the park, some boys are playing basketball. There are some girls under a big tree. They're singing and dancing. What are those women doing? They are drinking tea. Look at the woman in a blue coat. Who's she? She's my mother. She is talking to Edward. Edward is her student. He is a good student. He studies hard. He's good at all the subjects. And he's friendly to all his teachers and his friends.
