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

Nowadays almost everyone in the world have had a contact with computers. A great part of them has been using international computer’s net known as Internet.

I think using internet has more advantages then disadvantages. First of all, Internet provides access to a lot of information. Some of them are very useful in your job other helps in your hobby. Searching the net with Google, you can find everything you want. You can also do shopping using Internet. Of course it has no sense to buying a roll, but if you need something inaccessible, you will be able to buy it in Internet shop. You need only to select what you want, fill in some forms and click ok. In a few days you will get what you have ordered directly to your home, without going anywhere. You can pay with your credit card, pay postman when you get the package, or transfer money from your bank account. Nowadays almost every bigger bank offers transferring money with Internet. It is more faster then going to the bank and filling blankets. Transferring money in traditional way takes about a day, using Internet you can do this in few seconds even in Saturday and Sunday evenings. What’s more internet banks give you insurance against unauthorized transaction. Some people thinks that their money can by easily stolen by hackers. It isn’t true because the easiest way to steal your money from internet bank is breaking to your house and stealing you card of codes. Internet banks have very good protections witch make them practically unbreakable.

Next advantage of internet is email. Internet mails get in a few seconds in their destinations. It is very important when you want to send something for example to Australia. Of course you can send not only texts. You can email whatever you want, movies, photos, songs, computer programs etc. Costs are very important advantage of emails. Sending an email is much cheaper then phoning, or sending normal letters.

Beside a lot of advantages, Internet has some disadvantages too. First of disadvantages is that people who spend too much time sitting in the front of computer can easily gets ill. Radiation emitted by computer’s screen is harmful to eyes. People who spend too much time at their homes (because they needn’t go anywhere, they can do everything using Internet) are getting weaker. Sitting a for long time is also harmful to the spine.

Second disadvantage is that Internet can by addictive. Some people just can’t live without it. They have no real friends and when Internet is down they are getting furious.

Internet has some opponents but more and more people treats Internet like telephone, or radio. They use it for fun and work, and I think at present living without internet would be quite difficult.

In the age of technology, laptop is used widely. The laptop brings us a lot of benefits for our live. it is very versatile as it can do many things. firstly, it is portable. therefore, people can take it everywhere. secondly, it is economical so everyone don't have to spend too much money to buy it. besides, the laptop is a mean of entertainment. we can use it to listen to music, to chat with friends, to make video call with parents, to play games, and so on. last but not least, we can use laptop for studying. for example, the laptop can be used for researching topics on the Web or typing the assignment as well. In summary, laptop is definitely one of the greatest inventions in the world as well as the best thing in our society.

Nowadays, media development has many positive influences in human’s life. People have lots of sources to get information and take entertainment such as television, radio, Internet, etc. but nobody can deny the importance as well as the benefits of reading books.

First, reading books helps us widen our knowledge. Vietnamese has a proverb which means that we should travel to broad our understanding, if we always stay at home with our mother, we will never be wise. However, nowadays, not only does reading books costs less money but it is also more comfortable than taking a trip. We just lie on the couch and comprehensive what is happening in the books. Thanks to the wide range of books such as science, literature, astronomy, archeology, biology, physics, etc. we can get information focus on our own fields as well as the others. The more books we have read, the more knowing we have obtained.

Secondly, reading books helps us improve our expression ability like writing and speaking. The writing style of some our favorite writers will affect ours. Especially, when we read foreign literature, we will not only know more about that country but also have chance to improve our reading skill, learn new words which can be used to better our essays.

Last but not least, reading books helps us relax after a hard-working day. It is also an interest for everybody who does not like to visit crowded places at the weekend. They like quiet atmosphere and do not want to disturb anybody so they consider books as their close friend. They meet their stories, their lives in books and they feel extremely sympathetic with the characters’ situations. Reading books makes them happy and relieve stress.

In conclusion, reading books is so important and has many benefits. It not only help us become more clever but also bring us happiness. Therefore, everyone should be encouraged to read books as much as possible.

Vietnamese food is varied and distinctive. It is considerably low fat and high in carbonhydrates. Traditional Vietnamese cooking usually uses fresh ingredients, little dairy and oil, and various herbs and vegetables. Different sauces such as fish sauce, shrimp paste, ans soya sauce are quite popular in various regions.

There is no concept of ‘ course’ in a Vietnamese meal. A meal consists of various dishes( meat, fish, egg or tofu), vegetable, soup and rice. Rice is the staple in Vietnam. In many families, people eat ariund a tray of food with a small bowl of fish sauce in the middle. Around this bowl are dishes. If people place the food on a table, a similar arrangement is followed. In general, Vietnamese food is considered healthy and is popular in other countries.

        English is a common language that is quite diffucult to understand and to learn. But there are many countries that speak English, making English as their native language. America is one of them. America is an English-speaking country. English is a common language in America. As  you know, America is very developed, and this developed country is using 1 international language, that is English. And as I know, most Americans speak Englishs .Due to the fact that a few hundred years ago, Colossians discovered. Although American and English are 1, but in there are still some words different from English like football (soccer) or some words with "u" missing word like color (colour) or neighbor (neighbour). English is very diverse, and our country is starting to use English as a second language.

Topic 3:

There are many types of environment pollution in the world, air pollution is one of them. The main cause of air pollution is the smoke and dust released from factories. They are very toxic to us humans. And they are also very bad for the environment. In addition, air pollution is also generated from the exhaust fumes of motor vehicles such as motorcycles and cars. As a result, the air source in the flock is heavily polluted, causing a greenhouse effect, causing the Earth to heat up. The ice from the North and South poles is being melted due to rising sea levels, causing flooding. We need a way to fix them immediately, otherwise the consequences will be even more dangerous.

1.

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.

Groundwater

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.

Currently, in the world, people have made thousands of statistics on environmental pollution and climate change of the earth. From pollution of the marine and air environment to human deforestation and forest fires ... that has affected not only human life but also the lives of more than a few. million other animals. Therefore, we have solutions at the moment that are to reuse natural energy sources, collect wastes that pollute the environment that have a long decomposition time ... but in the future. In the future, people will have to have more effective solutions such as manufacturing vehicles that do not affect the environment, using fossil fuels, solar energy and wind energy ... To contribute improving the living environment and natural climate around us.

topic 1: in the family, the woman plays a huge role. They help the men take care of children and pregnant homes. Women take care of reasonable expenses for the family. They also play a big role in family balance, without us, without us, the woman responsible for giving birth in the family and contributing to family planning in some countries. Therefore, we can conclude that women not only play a huge role in the family but also in society.
