Last week, we did a survey among 2,600 students on "Who Is Your Idol ".
The survey shows that half of the girls choose film and TV stars as their idols, while 48 percent of the boys are fond of sports stars. As the picture shows, “parents” ranks the second for the girls, but the fourth for the boys. However, 18 percent of the boys choose “great figures”, the same as that of the girls.
As for me, Thomas Edison is my idol, because his inventions have greatly changed our life.
图表类说明文一般分三段。第一段直接点明本图表所反映主题，即_______。一般直接给出作为行文参考。

Step Two（课堂体验：我爱读范文）

假如你是李华，下面是你最近对你校100名高一学生早餐情况的一份调查表。请根据这份调查表所提供的情况写一篇120字左右的短文，并呼吁同学们认真对待早餐，说明不吃早餐会对身体带来不利的影响。
文章的开头已经给出，请接着写。
参考词汇：treat…seriously认真对待; nutrition n.
营养 nutritious adj. 营养的; appetite 食欲，胃口

Recently our school has made a survey among 100 students of senior one in our school.
From the survey, it can be seen that about 45 percent students go to school without breakfast while 35 percent students do not treat breakfast seriously. Only 20 percent students have enough breakfast with enough nutrition every morning. The reason lies in the following facts. Some students don’t get up early and can’t spare any time for breakfast. Some don’t have a good appetite and don’t feel like eating anything. Besides, some parents are so busy that they don’t have enough time to prepare breakfast for their children.
I hold the belief that it won’t do good for us students to go without breakfast. It’s not good for our health. Therefore, we should have enough nutritious food for our breakfast.
