阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

The First Lesson of the New Term, a TV program about how to protect oneself in times of emergency, is meant to provide school students with the knowledge on self-protection. It will help students in case of natural disasters such as earthquakes, fires, snowstorms or floods. Many examples show that enough knowledge about self-protection along with enough courage and willpower can help many survive.

The most recent example is from the earthquake in Sichuan Province in May of 2008. While thousands of school kids were killed by collapsed school buildings, all students from a middle school survived even without a single one being hurt. That’s because of their timely and orderly evacuations (撤离), which they had been drilled in every term.

It’s good to see this program is the most important activity of a national campaign to make students be aware of personal safety. Chinese Education Ministry has called on all schools nationwide to give lessons on self-protection knowledge in times of emergency every term.
