Air pollution is one of the most dangerous types of pollution in our world and in my area. Air pollution occurs when harmful or excessive quantities of substances including gases, particles, and biological molecules are introduced into Earth's atmosphere. It may cause diseases, allergies and even death to humans; it may also cause harm to other living organisms such as animals and food crops, and may damage the natural or built environment. Both human activity and natural processes can generate air pollution. Here are many causes of air pollution: vehical exhaust fumes, fossil fuel-based power plants, exhaust from industrial plants and factories, construction and agricultural activities,household activities,...The health effects caused by air pollution may include difficulty in breathing, wheezing, coughing, asthma and worsening of existing respiratory and cardiac conditions. These effects can result in increased medication use, increased doctor or emergency department visits, more hospital admissions and premature death. The human health effects of poor air quality are far reaching, but principally affect the body's respiratory system and the cardiovascular system. Individual reactions to air pollutants depend on the type of pollutant a person is exposed to, the degree of exposure, and the individual's health status and genetics.The most common sources of air pollution include particulates, ozone, nitrogen dioxide, and sulphur dioxide. Children aged less than five years that live in developing countries are the most vulnerable population in terms of total deaths attributable to indoor and outdoor air pollution.

America is an English-speaking country. English is a common language in America. As you know, America is very developed, and this developed country is using 1 international language, that is English.

Although American and English are 1, but in there are still some words different from English like football (soccer) or some words with "u" missing word like color (colour) or neighbor (neighbour). English is very diverse, and our country is starting to use English as a second language.

1. Write about a natural disaster you have read about.
The most destructive disaster that I have experienced was the flood in 2012, in Thanh Hoa province. It had been raining heavily for many days. All homes, trees and animals were flooded. The water got to the roof of houses. Damage was caused to property and people. Many people were injured and died. Rescue workers helped people trapped in the flooded houses and they brought people who were left homeless to safe place. My house was flooded but we had been evacuated before. Although the time has gone by, I still can’t forget that terrible disaster.
