The current environment is heavily polluted by industrial waste, domestic waste, traffic smoke ... With the population growth rate and the growth rate of industry and activities. With the current urbanization, the cultivated land area is narrowed down, and the quality of land is degraded more and more. For polluted water, it reduces the diversity of organisms in the water. Water pollution is caused by different types of water, industrial wastes are discharged into river basins but have not been properly treated; chemical fertilizers and pesticides that seep into groundwater and pond water; Domestic wastewater is discharged from riverside residential areas causing serious pollution, affecting the health of people and creatures in the area. Air pollution is caused by exhaust gas from factories, exhaust gas from vehicles makes the air not clean or causes unpleasant odors, and loss of vision when looking far away due to dust. Thus, the polluted environment is a threat to human life. We need to sound alarm bells to wake up everyone, we need to join hands to protect the environment.

Soil pollution is a consequence of human activities that alter ecological factors that cross the ecological boundaries of the communities living in the soil. The land environment is home to human beings and most of the shallow creatures, the foundations for civil, industrial and cultural constructions. Land is a precious resource, people use land resources for agricultural production to ensure food supply for people. But with the pace of population growth and the pace of industrial development and urbanization, the area of ​​arable land is shrinking and land quality deteriorates, the average land area head drops. Parularly in Vietnam, the actual depletion of land resources is very worrying and serious.  What do we need to do to protect the environment? That is the question that every one of us needs to answer. In my opinion, protecting the environment is the responsibility of the whole community. Everyone must have a sense of protection. The green, clean, beautiful environment will make our lives better. From the house to the alley, from the alley to the school etc. The place is also clean and airy, many trees, air will be fresh, health will be guaranteed. That everyone wants. At present, I see my class, our school where the concentration of people, not very clean, garbage also lunged, trees are still less. On the street, there are public trash but few people put garbage in the bin, you do not throw it, making the street scene is not beautiful. To protect the environment, I feel we must always have a sense of environmental protection in parular: Do not throw garbage indiscriminately, do not discharge dirty water into ponds, do house cleaning, alleys, schools, not breaking flowers ... and propaganda for people always have common sense and responsibility for environmental protection.

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.

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 !
