Exercise 1:
Air pollution is measured by a number called the Air Quality Index (AQI), which ranges from 0-500, with anything over 150 considered “unhealthy.” The World Health Organization considers any reading above 100 to be hazardous and recommends that people avoid prolonged exposure. While Vietnamese cities such as Hanoi and Ho Chi Minh City have AHI readings around 100 or higher, many provinces have far worse levels of pollution. In some areas of the south, where there are large rubber plantations and coal mines, AQI numbers can surpass 500.
(Ô nhiễm không khí được đo bởi một con số gọi là Chỉ số Chất lượng Không khí (AQI), có khoảng từ 0 đến 500, với bất cứ cái gì ở trên mức 150 sẽ được coi là “độc hại”. Tổ chức Y tế thế giới WHO cho rằng với mỗi lần đọc mà chỉ số trên 100 thì nghĩa là ở mức nguy hiểm và khuyến cáo mọi người tránh tiếp xúc lâu ở bên ngoài. Trong khi những thành phố ở Việt Nam như Hà Nội và thành phố Hồ Chí Minh đọc được chỉ số AHI khoảng 100 hoặc hơn, nhiều tính khác có mức độ ô nhiễm tệ hơn rất nhiều. Ở một vài vùng ở miền Nam, những vùng trồng cao su và mỏ than thì chỉ số AQI có thể vượt qua 500.)

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 !

Perilous pollutants may contain various types of impurities including harmful chemicals, dissolved gases, suspended matters, dissolved minerals, and even microbes. All the contaminants reduce the level of dissolved oxygen in the water and affecting the lives of animals and human beings to a great extent. Dissolved oxygen is the oxygen present in water required by the aquatic system to continue the lives of plants and animals. However biochemical oxygen is the demanded oxygen by the aerobic micro-organisms to oxidize organic matters of wastes. Water pollution is caused by two means, one is natural water pollution ( due to the leaching of rocks, decay of organic matters, decay of dead matters, silting, soil erosion, etc ) and another one is man-made water pollution ( due to the deforestation, set up of industries near large water bodies, high level emission of industrial wastes, domestic sewage, synthetic chemicals, radio-active wastes, fertilizers, insecticides, pesticides etc )
II. Read the passage and complete the sentences. True (T) or false (F).
Air pollution is a serious problem in many cities. Motor vehicles, factories and other sources create so much air pollution that it may hang in the air like dirty fog. Air pollution threatens the health of the people who live in cities. City wastes cause water pollution when they are poured into the waterways. These wastes kill fish and make some areas unfit for swimming. In addition, many large cities have difficulties in disposing of their garbage. The amount of garbage grows each year, but places to put it are quickly filling up. Citizens, governments, industries, scientists, and business people must work together in different ways to gradually reduce pollution. For example, most cities have introduced recycling programmes.
