Some students get up late; others prefer to stay in bed for a few more minutes. That's why many of them just skip breakfast. It’s very bad for health. In the morning students usually have four classes. It’s a long time before lunch. If they don’t eat anything for breakfast, they may feel hungry and they can’t listen to the teacher carefully. Study shows that people who do not have breakfast think slowly that day. Besides, teenagers need extra energy when they are growing. Therefore, having a good breakfast is very important for students.

用其他简单的词句代替，或是用类似的词，还有一般题目里就有关键词了，比如关于 “大学生心理问题” 的 关键词是 “psychological problem”，“psychological problem”肯定会告诉你的！

我在一篇例文里是看到有人举了自己的例子的，并且描写生动详略得当。
个人觉得200字以内很难把自己的事例说清楚，还是举名言或典型事例好些。
不过你要举应该也是可以的。
