Energy is fundament to human beings.We have 2 energys:renewable energy and non-renewable energy.Now,we use and used the non-renewable energy.It like:Coal,natural gas,....But it is make a lot of smoke.So in the future,we will use nenewable energy.Like biogas,it is used for cooking and heating,but also provide energy for public transport.Moreover,it is made from plant waste and animal minute.Is almost nothing.

Renewable energy or renewable energy is energy from renewable sources that are indivisible, such as solar, wind, rain, tides, waves and geothermal energy. The basic principle of using renewable energy is to extract some of the energy from continuous processes in the environment and put it into technical use. These processes are often promoted especially from the Sun. Renewable energy replaces traditional fuels in four areas: electricity generation, hot water heating, engine fuels, and rural independent power systems.
With 9 clean energy sources for future use
1. Fuel cell.
This is a technique that can provide human energy without emitting CO2 or other toxic waste. A typical fuel cell can generate direct electricity by reacting hydrogen and oxygen. Hydrogen can be obtained from many sources such as natural gas, methane from organics waste and from non-burning so they do not have toxic emissions.
2. Solar energy
Solar power transmission.
3. Energy from the ocean.
This is an extremely rich source of energy, especially in large marine areas. Waves and tides are used to spin turbines. Power sources can be used directly for marine equipment such as lighthouses, buoys, wharves, navigation systems
4. Wind power
Wind energy is considered to be a great source of green energy, abundant and available everywhere. One could use wind to spin the turbines.
5. Vegetable waste oil used to drive cars
Vegetable oil when discarded, if not utilized, will cause great waste and pollute the environment. To overcome this situation, a Japanese company called Someya Shoten Group in Sumida Prefecture in Tokyo has recycled these oils for soaps, fertilizers and VDF oils without sulfur oxide residue. From black waste to only one third compared to traditional oils.
6. Energy from snow
Japan's Bihai Natural Energy Research Association has succeeded in applying snow to freeze warehouses and air conditioners in buildings in hot weather. According to this project, snow is stored in warehouses to keep the storage temperature from 0oC to 4oC. This is the ideal temperature for preserving agricultural products, thus reducing production costs and reducing production costs.
7. Energy from bio-fermentation
This energy source is generated by the bio-fermentation of domestic waste.
8. Geothermal energy
This is the source of energy deep in the heart of the islands, volcanoes. This source of energy can be obtained by draining hot water from thousands of meters underground to run an electric turbine.
9. Methane hydrate
Methane hydrate is considered to be a potential source of deep underground energy, white as ice, the culprit for gas congestion, and is known as "ice can burn". Methane hydrate is a crystalline substance composed of water and methane, which is stable at low temperatures and high pressures, most of which are found beneath the permafrost and deep layers beneath the Great Depression. Positive and a good substitute for oil and coal.

The advantage of this energy source is that it is clean, available in nature, polluted, not exhausted and is the best solution to save fossil fuels for the future.

Dear guests, I’d like to talk to you today about renewable and non-renewable energy. Fossil fuels are non-renewable energy sources. They include oil, coal, and natural gas. They can be used to create energy, generate electricity, or drive big machinery. Unfortunately, they are harmful to the environment. Viet Nam still relies mostly on non-renewable energy sources, however, hydro power is increasingly used here too.

Hydro and nuclear power can generate a great deal of energy. They are renewable and plentiful. However, hydro power is limited because dams cannot be built in certain areas. Nuclear power can provide enough electricity for the world’s needs, but it is dangerous. The sun and the wind are other alternative sources of energy. The wind turns turbines to

make electricity. Solar power can be converted into electricity. It can be used to heat or cool our houses. Although there are some disadvantages, these alternative energy sources can offer abundant amounts of clean, safe electricity. They will be valued more and more in the future in Viet Nam.

2.What are the disadvantages of hydro and nuclear power?

3.Why do you think the wind and the sun are called alternative sources of energy?

4.What types of energy does Viet Nam use most?

5.What does the professor think Viet Nam will use more in the future?

1.How many types of energy sources are mentioned in the text? What are they?

Two. They are renewable and non-renewable.

2.What are the disadvantages of hydro and nuclear power?

Hydro power is limited because dams cannot be built in certain areas. Nuclear power is dangerous.

3.Why do you think the wind and the sun are called alternative sources of energy?

Because they are natural sources of power and we use them instead of non-renewable sources to get the electricity we need.

4.What types of energy does Viet Nam use most?

We use non-renewable sources of energy the most but we are increasingly using hydro power.

5.What does the professor think Viet Nam will use more in the future?

He thinks Viet Nam will use the wind and the sun as alternative sources of energy in the future

Now I present my project. It name is Icon. It use solar energy and wind energy. It can fly, swim and go on the road. In my opinion it’s doesn’t need a driver. Learning to drive this Icon is not easy because Icon very fast and big. It travels aroud 5000 kph. It look like very beautiful. Icon has benefits: very fast, it can fly, swim and go on the road. But it also has disadvantages: learning to drive this vehicel very difficult, It can only carry two people. I love It very much. I want have a one in the future.

TOPIC 1:

Bat Trang Porcelain Village is a traditional pottery-making village, which is located in the Northern of the Red River, Bat Trang town, Gia Lam district, Ha Noi. The pottery here is made of a special kind of clay – the white clay.
The craftsmen only use their hands to knead the clay into the shape of the bowl, flower vase, etc. Then, they draw lively pictures or patterns on the products and glaze them. After that, these kneaded-clays will be put into the kiln for heating.

The pottery products of Bat Trang Porcelain Village are always famous for the skillfulness, subtleness and the diversity of product’s shapes such as small bowls, large bowls, flower vases, pots, thuribles, etc. Especially, all the handicrafts of this pottery-making village are waterproof and fade-resistant.

The glaze of Bat Trang is also very subtle and unique with the secret recipe, which is handed down from generation to generation. Those values have created such an irresistible attraction and appealing feature for Bat Trang village. This is the reason why this traditional handicraft village can attract so many tourists as well.
