introduction：
natural disasters occur throughout the world, and china, as you probably know, has a particular problem with earthquakes. in the last century five of the ten worst earthquakes happened in china. although it is important for us students to understand the dangers people face in a quake, it is just as important for us to realize that there are things that can be done to minimize(降低) the damage caused by quakes. for this reason, this unit keeps a positive tone or outlook(观点). it includes exercises and tasks that enable us to think about how to avoid earthquakes, or at least some of the damage they can cause. this unit also lets us role-play community work that deals with disaster relief(救援).
