Flood is a kind of Natural Disaster which hurts or even kills people and animals. Flood can also damage houses, factories, public places, etc. There are some efforts to minimize flood. First, we must not cut down the trees in the forest illegally, because it can cause many disasters for human beings, one of which is a flood. Second, We should plant any kinds of trees in our house, in the barren area or on the side of the road, so the water can be absorbed easily by the root of the plants. Besides, in this way we get many advantages such as to decrease air pollution and to support the 'Go Green' program for Global Warming and Climate Change on our earth. The last is that we must not throw away rubbish. By doing those simple efforts, we can minimize the disasters and participate in the preservation of our environment. So, we must keep our environment.

I consider the earth quake in 2011 was the most horrible and frightful in my life. A magnitude 5.5 earthquake centered off southern Vietnam in November 2001, killed one person after a plank loosened by the shaking fell on his head. Many houses were damaged, and several people were injured as they tried to escape from their homes, including some who jumped from balconies.Luckily, none of deaths. Some schools and office buildings damaged by the quake were closed for inspection. Dien Bien Phu was the site of a key victory by Vietnamese forces against French colonialist forces in 1954. After the quake, many residents of the town stayed on the streets all night and did not dare to go back into their houses until morning,People in the whole town could not sleep for fear of another quake. Earthquakes occur infrequently in VietnamThe quake was the worst to hit Vietnam in a decade. Damage from Vietnam earthquake estimated at $13 million.
