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
Our non-renewable energy sources such as coal, oil, and natural gas will (1) _______run___ out of in the future. That's the (2) ____reason______ why we are looking for alternative sources of (3) _______energy___ which are cheap, clean and effective. These (4) ____kinds______ of energy will not cause (5) _____pollution_____ or waste natural resources. (6) _____Renewable_____ power is one of them. It's currently the cheapest source of large-scale renewable energy.
Most wind energy is produced from turbines that have three 60-meter-long blades. The wind spins the blades, which turn a shaft connected to a generator that produces (7) ____electricity______. Now, mass production and technology advances are (8) ______made____ turbines cheaper. In 2000, cumulative wind capacity (9) ____of ______the world was 17,000 megawatts. Fifteen years later, this number increased sharply to 430,000 megawatts. It is predicted that with this pace of growth, (10) in 2050 one third of the world's electricity needs will be fulfilled by wind power.
1. _T__ Many people in Calcutta live in bad conditions because they have no jobs.
2. _T__ Babies from poor families are taken care of by the local government.
3. _F__ Seventy percent of the families in Calcutta have to live in the streets.
4. _F__ The local government makes effects to help poor families but it cannot solve the problem
successfully.
5 .__T_ Many people in Calcutta live in good conditions because they have no jobs.
6. _F_ Babies are born in the street.
7. __F_ Many people are sick because they don’t have enough money to live.
1. Non - renewable sources are being used up. T
2. Many poor people in developing countries do not have little electricity. F
3. Biogas is a new source of energy available for poor people. T
4. Biogas creates a lot of smoke. F
5. The new energy source is not costly T
Energy is fundamental to human beings. Many poor people in developing countries do not have modern sources of energy like electricity or natural gas, with which their life can be improved.
People who live in mountainous areas have to gather wood for fuel. This takes a lot of time. For many people living in rural areas, biogas is the largest energy resource available. The main use of biogas is for cooking and heating, but it can also provide energy for public transport. As biogas is smoke-free, it helps solve the problem of indoor air pollution. Moreover, it’s made from plant waste and animal manure. They cost almost nothing.
The tendency to use renewable energy sources in developing countries is on the increase as non-renewable ones are running outệIn the future, the wind and the sun will be used as the most important environmentally friendly energy sources.

In the modern world, people depend on energy to power their everyday lives. A wide range of power-run devices and modern conveniences (1) are taken for granted, and although it may seem that we will not be in danger of living without those conveniences, the fact is that many supplies of energy are running out rapidly. Scientists are constantly (2) searching for new sources of energy to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend (3) on the success of this search. Coal, oil and natural gas are now being used widely. (4) However, not only are supplies of , these supplies are limited, and they are a major source of pollution. Therefore, the existing alternative energy sources must be improved or futher explored and developed. These include nuclear, water, solar, and wind power, as well as energy from new, (5) nonpolluting types of fuels types of fuels. Each of these, however, has advantages and disadvantages.

Fossil fuels are non -renewable energy soircecs.They include oil,coal,and natutal 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.
