四、Draw and say. 请你仿照例子，先画一画家人的职业，再用英语介绍一下吧！

This is my father. He is a driver.
This is my mother. She is a nurse.
They all love their jobs.

示例：
画图部分参考：画一位站在黑板前讲课的男士代表爸爸，画一位在超市收银台工作的女士代表妈妈。
介绍语句：
This is my father. He is a teacher.
This is my mother. She is a shop assistant.
They all love their jobs.

这是一道开放性英语实践题，我们可以先选定1-2位家人的职业，画出对应职业的相关形象，比如画站在讲台前讲课的人物、在医院工作的人物等，再仿照给出的基础句式，用四年级已学的职业类英语词汇组织简单语句完成介绍即可。
