词语赏析：表达转折关系，使得上下文衔接自然，并把话题转移到保护自己的事情上来。
The kitchen is dangerous because there are so many glass objects. Also，never get into a lift during an earthquake.
If you are outside，get to an open area as fast as you can. Stay away from buildings and trees. If you are in a car，pull over to a place where there are no trees or tall buildings and stay in the car. ③ If you are close to the sea，try to get as far away from the water as possible.④ Earthquakes can cause huge waves that can really harm the people nearby.
When the earthquake is over，there is still plenty of danger. If you see a fire，quickly move outdoors to an open area. Keep an eye out for things that can fall on you. ⑤ If you have a phone，use it only once to call your family or a friend. Too many calls will bring down the phone system. ⑥ Your chances of survival in an earthquake go up if you stay calm. Staying calm is not easy，but it can save your life.
