Topic 1: Write about types of pollution.
P/s : Chi 1 cai o nhiem thoi ...
Nowadays there are a lot of types of pollution such as : air pollution, water pollution, visual pollution .... and noise pollution. Noise pollution is constant and loud sound. To measure the loudness, or volumn of sounds , people use a unit called a decibel. When a sound is louder than 70 decibels, it can cause noise pollution. Do you know that the noise from a vacuum cleaner or motorcycle can result in permanent hearing loss after eight hours ? The sounds of a concert are even more serious. Noise pollution can also lead to headaches and high blood pressure. If you are listening to music throughout headphones, and other people can hear it, it means the music is too loud and unsafe.

Topic 2 : Talk about natural diasters and ways to prepare for them.
Today, there are more and more natural disasters that most people affect. In my opinion, we can't prevent natural disaster but we can have some preparation for them. There are many types of natural disasters but typhoon is a popular in our country. Firstly, typhoon is a tropical storm with wind and heavy rain. When it strike, it can weak havoc across large areas and effect lot of life or extensive damage to property . Flood can be happened by long heavy rain and people also can be became homeless. Last year lots of people were seriously injure in a typhoon. Natural disasters are also very dangerous but we also have some simple preparation . The first step is learnt about the risk in your area and read the information about natural disasters on gorvernment site. Next, find out that the rescue and emergency workers advice. It 's also important that you put together emergency supply it and should include food, water, medicine, document, and some money. Finally , plan safe places to meet your family and get to know the evacuation routes and shelter. In short, everyone sholuld protect environment to reduce this natural disasters.
3) Talk about ways of communication now and in the future.
Communication is a neccesary for eberyone. In present , there are three basic forms of communication: verbal, non-verbal and multimedia.
First, verbal ( meeting F2F) is a important way of communication help you success. I like hanging out with my friends and my friends and when I meet F2F with them I feel very confident. It explains why I can speak English easily. Let ' s try! You will have a great time. Secondly, you have a different thing to say non- verbal ( using signs ) will be a good choice. For example, you make your mother sad , you can use a sign to say ' sorry ' to her. Thirdly, with develop of science and technology , many multimedia appear such as video chatting , emailing,... You can know more information despite you still stay at home. But in the future, we can use telepathy or holography. Telepathy uses a tiny device place into our head. We will be communicating just by thought over the network. Holography will help us in our work. Even though, I prefer to chat with my friends. Life is more meaningful that way !

Water is uniquely vulnerable to pollution. Known as a “universal solvent,” water is able to dissolve more substances than any other liquid on earth. It’s the reason we have Kool-Aid and brilliant blue waterfalls. It’s also why water is so easily polluted. Toxic substances from farms, towns, and factories readily dissolve into and mix with it, causing water pollution.
Categories of Water PollutionGroundwater
When rain falls and seeps deep into the earth, filling the cracks, crevices, and porous spaces of an aquifer (basically an underground storehouse of water), it becomes groundwater—one of our least visible but most important natural resources. Nearly 40 percent of Americans rely on groundwater, pumped to the earth’s surface, for drinking water. For some folks in rural areas, it’s their only freshwater source. Groundwater gets polluted when contaminants—from pesticides and fertilizers to waste leached from landfills and septic systems—make their way into an aquifer, rendering it unsafe for human use. Ridding groundwater of contaminants can be difficult to impossible, as well as costly. Once polluted, an aquifer may be unusable for decades, or even thousands of years. Groundwater can also spread contamination far from the original polluting source as it seeps into streams, lakes, and oceans.
Surface water
Covering about 70 percent of the earth, surface water is what fills our oceans, lakes, rivers, and all those other blue bits on the world map. Surface water from freshwater sources (that is, from sources other than the ocean) accounts for more than 60 percentof the water delivered to American homes. But a significant pool of that water is in peril. According to the most recent surveys on national water quality from the U.S. Environmental Protection Agency, nearly half of our rivers and streams and more than one-third of our lakes are polluted and unfit for swimming, fishing, and drinking. Nutrient pollution, which includes nitrates and phosphates, is the leading type of contamination in these freshwater sources. While plants and animals need these nutrients to grow, they have become a major pollutant due to farm waste and fertilizer runoff. Municipal and industrial waste discharges contribute their fair share of toxins as well. There’s also all the random junk that industry and individuals dump directly into waterways.
Ocean water
Eighty percent of ocean pollution (also called marine pollution) originates on land—whether along the coast or far inland. Contaminants such as chemicals, nutrients, and heavy metals are carried from farms, factories, and cities by streams and rivers into our bays and estuaries; from there they travel out to sea. Meanwhile, marine debris—particularly plastic—is blown in by the wind or washed in via storm drains and sewers. Our seas are also sometimes spoiled by oil spills and leaks—big and small—and are consistently soaking up carbon pollution from the air. The ocean absorbs as much as a quarter of man-made carbon emissions.
Point source
When contamination originates from a single source, it’s called point source pollution. Examples include wastewater (also called effluent) discharged legally or illegally by a manufacturer, oil refinery, or wastewater treatment facility, as well as contamination from leaking septic systems, chemical and oil spills, and illegal dumping. The EPA regulates point source pollution by establishing limits on what can be discharged by a facility directly into a body of water. While point source pollution originates from a specific place, it can affect miles of waterways and ocean.
Nonpoint source
Nonpoint source pollution is contamination derived from diffuse sources. These may include agricultural or stormwater runoff or debris blown into waterways from land. Nonpoint source pollution is the leading cause of water pollution in U.S. waters, but it’s difficult to regulate, since there’s no single, identifiable culprit.
Transboundary
It goes without saying that water pollution can’t be contained by a line on a map. Transboundary pollution is the result of contaminated water from one country spilling into the waters of another. Contamination can result from a disaster—like an oil spill—or the slow, downriver creep of industrial, agricultural, or municipal discharge.
