Nowadays, one of the biggest problems human are facing with is water pollution. Water pollution is defined as the presence in groundwater of toxic chemicals and biological agents that exceed what is naturally found in the water and may pose a threat to human health and/or the environment. A lot of causes are responsible for this issue. And they lead to extremely bad consequences. I’d like to explain more in the following paragraphs.
Some typical causes of water pollution are Industrial waste, Sewage and waste water, Mining activities, Accidental Oil leakage, Burning of fossil fuels, Chemical fertilizers and pesticides, … These agents contribiute to water pollution.
And the consequences? Of course, it is human health! Human are likely to get into trouble with some diseases such as hepatitis by eating seafood that has been poisoned. Water pollution also brings about the death of aquatic (water) animals, Disruption of food-chains, Destruction of ecosystems.
In conclusion, water pollution is a alarming problem that needs to be solved as soon as possible. The sooner we solve it, the more healthy we are.
Causes of environmental pollution: Wastes of domestic and industrial activities contamination, throwing garbage indiscriminately into the river, agricultural activities: use of pesticides, and fertilizers discharged into the river
Water pollution not only causes direct dangerous consequences to the health and lives of people, animals, and plants on the planet but also leads to an increasingly declining economy. Therefore, we need to treat waste before discharging it into the environment, not littering and raising people's awareness of protecting the water environment.
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 !
