The power of nature
There are some things in nature that we cannot stop from happening. We cannot stop the power of nature. A flood comes when there is too much water on the land. Sometimes， it is after a big storm when too much rain falls on the land. Sometimes it is after a big storm at sea， when too much sea water comes onto the land. The fast flood water can hurt us and can hurt our homes. We cannot stop a flood from coming， but we can try to stop the water from coming into our homes. We can try to stop the water by making a wall. We can use sandbags to make the wall.
An earthquake comes when the land moves. The land goes up and down and in different directions. Then land can crack（断裂）. An earthquake can hurt us. We can get hurt by things that fall down in an earthquake. Falling things can start fires. We cannot stop an earthquake from coming， but we can try to make our homes strong so that they will not fall down in an earthquake.
A tornado（龙卷风）is fast air that goes around and around over the land. A tornado can pick up anything. It can break anything that is in the way. A hurricane（飓风）is a big storm with fast winds and strong rain. It begins at the sea and can come onto the land. Its fast winds can hurt us and our homes. We cannot stop a tornado or a hurricane from coming， but we can get out of its way. We cannot stop the power of nature， but we can go to places where we can be safe.
