Water pollution is a source of water contaminated with chemicals or foreign toxins that are detrimental to the health of users, plants or animals. Water pollution occurs when harmful substances enter water bodies such as lakes, rivers, oceans, etc., which can be dissolved, suspended or deposited in the water. The water pollutants include: fertilizers and pesticides from agricultural production; wastewater and waste from food processing; lead, mercury and other heavy metals; Chemical waste from industries. It leads to many consequences. Almost all types of water pollution are harmful to the health of humans, animals and plants. Heavy metals from industrial processes can accumulate in nearby lakes and rivers. They are toxic to marine organisms such as fish and shellfish, and subsequently to those who eat them. Sulfate particles from acid rain can harm the health of organisms in rivers and lakes. And many consequences more. How to solve this problem? We can treat waste water properly, lractice green agriculture, have law and policy against water pollution, treat Industrial wastewater,......This is my talking aboute water pollution. Thanks for listening

1. Talk about one of the wonders in the world

Ha Long Bay is one of the seven natural wonders in the world. Ha Long Bay is located in Quang Ninh province which is in the north of Vietnam. It is nearly 200km from Hanoi. So it takes you about 4 hours by car. You can also travel there in a coach or even in a helicopter on Saturday. The best season to visit Ha Long is in summer when the weather is warm and sunny. Ha Long Bay has many beautiful caves and islands; therefore, you must take a boat trip to enjoy the view here. You certainly must take pictures to remember the trip better, too. If you are an active person, you must do the water sports here like swimming, sailing, and windsurfing. One more thing, you must try the seafood here because it is incredibly fresh and delicious. With this travel guide, I hope that you will have a wonderful time here in the number one natural wonder of Vietnam.

2. Talk about your hobby

There are countless things that I love in this world. But the thing I love most is reading book. I started this bobby when i was 8 years old. I often reading books whenever and wherever I can. I read news, story books and novels and especially have passion for discovery books. Reading is an incredibly inexpensive hobby that provides so many benefits. Book help me widen my knowledge of the world. When I am sad or disheartened, I often mix myself with book. I realize that the life has many meanful things than i thought and i need to try my best for my bright future. Book also bring me more motivation and joy of life. All of parents want to give their children a quality education. I think the best method is let them read book, regardless of any kind of books, as long as those book are wholesome books. I have no intention of of this useful hobby. In future, I want to read and more book.

5. Talk about your favourite sport

I would like to talk about a sport that I particularly enjoy and have been practising for a few years. It is basketball. For me, this is not only a sport or a physical exercise but also an ideal way for me to relieve of stress and to make new friends.

I first knew about basketball when I was a little kid through a video game called NBA 2k8. However, at that time I did not play badminton at all, partly because I was not an active kid who was aware of the critical importance of physical exercises. When I went to high school, a lot of my friends were a big fan of basketball and my high school offered big playgrounds for sports activities, therefore I practised basketball much more often.

I usually play basketball in the weekends and watch NBA on the nights when my favorite team, the Los Angeles Lakers play. I often go to sports centres with a number of my classmates for basketball matches. Sometimes we even participate in local league, didn’t accomplish anything big but it was extremely fun.

For me, basketball is a good way to help me pursue a healthy lifestyle. It is also an affordable type of sport as you do not have to buy a lot of specialised sports materials. Finally, playing basketball enables me to develop a number of important and non-academic skills such as discipline, team-work, problem-solving and co-operation.

Hello everyone, today I'd like to tell you some information about types and sources of energy. Energy is classified into two main groups: renewable and non-renewable.

The energy generated from natural sources such as the sun, wind, rain, and tides is called renewable energy. They are plentiful and can be generated again and again. They also have low carbon emissions so they are considered green and environment-friendly. Moreover, using renewable energy can reduce your electricity bills. Unfortunately, solar energy can be only used during the daytime but not during night or the rainy season. Geothermal energy also can bring toxic chemicals beneath the earth's surface to the top and can create environmental changes.

Non-renewable energy is the energy taken from other sources that are available on earth.They are limited and will run out in the future. They can't be re-generated in a short time.Fossil fuels - natural gas, oil and coal - are examples of them. They are cheap and easy to use. However, when burnt, they release toxic gases in the air so they cause serious environmental changes such as global warming. And the important thing is that non-renewable sources will expire someday. 2. 1. Use public mode of transportation

Encourage people to use more and more public modes of transportation to reduce pollution. Also, try to make use of carpooling. If you and your colleagues come from the same locality and have same timings you can explore this option to save energy and money.

2. Conserve energy

Switch off fans and lights when you are going out. A large number of fossil fuels are burnt to produce electricity. You can save the environment from degradation by reducing the number of fossil fuels to be burned.

3. Understand the concept of Reduce, Reuse and Recycle

Do not throw away items that are of no use to you. In-fact reuse them for some other purpose. For e.g. you can use old jars to store cereals or pulses.

4. Emphasis on clean energy resources

Clean energy technologies like solar, wind and geothermal are on high these days. Governments of various countries have been providing grants to consumers who are interested in installing solar panels for their home. This will go a long way to curb air pollution.

5. Use energy efficient devices

CFL lights consume less electricity as against their counterparts. They live longer, consume less electricity, lower electricity bills and also help you to reduce pollution by consuming less energy.

Several attempts are being made worldwide on a personal, industrial and governmental levels to curb the intensity at which air pollution is rising and regain a balance as far as the proportions of the foundation gases are concerned. This is a direct attempt at slacking Global warming. We are seeing a series of innovations and experiments aimed at alternate and unconventional options to reduce pollutants. Air pollution is one of the larger mirrors of man’s follies, and a challenge we need to overcome to see a tomorrow.

TYPE OF NATURAL DISATER: Flood

WAYS TO PREPARE:

• – Check for local flood warnings if your area is at risk: look online or call Floodline.
• – Tune in to the local radio or television news for updates. Alert your neighbours, particularly elderly or vulnerable people.
• – Prepare an emergency kit, including emergency numbers, insurance policy, first aid kit, torch and water.
• – Use our home emergency contacts sheet so you have the numbers you need to hand, even if you lose power.
• – Have a list of irreplaceable items to keep safe and put important personal documents into a sealed bag.
• – Pack essential items you will need if evacuated – medication, clothing, toiletries and items for children.
• – Purchase unfilled sandbags and sand from builders’ merchants. Remember that, if there is a flood, demand may exceed supply – as people will rush to buy them.
• – Empty freezers and refrigerators, leaving doors open.
• – If you can, move any vehicles to higher levels.
• – If you have time, take photographs before you leave. This may help later with insurance claims.
• – Turn off the mains power and water, and take mobile phones and chargers with you. Put sandbags in toilet bowls to prevent sewage back-flow.
• – Shut windows, lock doors – and don’t forget to take your pets.

hello teacher, my nam i.... (giới thiệu bản thân) 

here, i will talk about my topic: talk about green activities and their benefits to the environment. The first is to plant trees. Trees help absorb Co2 and release gas 02, helping to cool the atmosphere. In addition, it provides shade, fruit and can store a large amount of watter. second, is waste recycling. It helps to treat wastes that pollute the environment, some plastics can even be processed for use. the third, choose green transport like carpooling, bus or bicycle. talking the bus helps reduce a part of emissions into the air, contributing to reducing the greenhouse effect. Cycling can both avoid tracffic jams in the city, improve your health,etc.... Thank you very much. 

activities: plant trees, recycle trash, clean the citiy

To reduce water pollution, we need not to litter indiscriminately, not to dump garbage in rivers, lakes, seas, etc. Do not dump waste into rivers, lakes or the sea. If we can do it, we will reduce water pollution.

-plant more trees because trees give more fresh air and reduce dust. They provide shade in the summer for students to relax after lessons

-put garbage bins around the school yard to prevent lazy students from littering

-sweep our school yard every day
