I. Read the passage and choose the best answer A, B, C or D to complete the passage.

The natural environment includes all natural resources that are necessary for life: the air, the oceans, the sun, andthe land. Because they are vital for life, these resources must be protected from pollution and conserved. Ecologists study their importance and how to (1).......... them carefully.

According to ecologists, resources are divided into two groups: (2).......... and non-renewable. When a resource is used, it takes some time to replaceit. If the resource can be replaced (3)........., it is called renewable. If it cannot be replaced quickly and easily, it is non-renewable. For example, grass for animals is a renewable resource. When cows eat the grass, the resource is used. If the soil is fertilized and (4).........., more grass will grow. Coal, however, is non-renewable because it takes millions of years to make coal.

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.

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

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?

IV . Choose the correct answers :

1. Remember to ....... the lights before going to bed .

A. turn B.turn off C.turn on D. stop

2. Biogas is .......... and cheap for cooking and heating .

A. dangerous B. abundant C. serious D. expensive

3. A hydropower station .......... in the North of the country next year .

A. was built B. were built C. will be built D. has been built

4. At this time next week , we ..... a wind turbine in our garden .

A. install B. installed C. will install D. will be installing

A. renew B. provide C. waste D. pollute

6. Hydro power is ......... because dams cannot be built in certain areas .

A. limited B. unlimited C. abundant D. enough

7. Why is it called a ..... source - Because it can be replaced easily and quickly .

A. effective B. available C. renewable D. non - renewable

8. Wave energy is a source of ........ energy .

Read the passages and choose the best answer to each of the following questions. (10 points)

Passage 1. Scientists often divide resources into two groups: renewable and non – renewable. When a resource is used, it takes some times to replace it. If the resource can be replaced quickly and easily, it is called renewable. If it can not be replaced quickly and easily, it is non- renewable. All fossil fuels are non-renewable resources. Solar energy, air, and water are usually called renewable because there is an unlimited supply.

However, this definition may change if people are not careful with these resources. The amount of solar energy that reaches the earth depends on the atmosphere. If the atmosphere is polluted, the solar energy that reaches the earth may be dangerous. If humans continue to pollute the air, it will not contain the correct amounts of these gases.

Many resources are limited and non - renewable, and many are in danger of pollution. As a consequence, resources must be conserved and the environment protected. Conservation must become an important part of everyone’s life.

1. How many kinds of resources are mentioned in the passage?

    A. 2 B. 3 C. 4 D. 5

2. Non-renewable resources are those which

A. are unlimited           B. can be replaced quickly and easily

        C. take million of the years to replace              D. are used every day such as solar energy and water

3. What will happen if the atmosphere is polluted?

A. The air won’t contain the correct amounts of natural gases

B. Life won’t continue as it does

C. Renewable resources will soon become non- renewable

D. All are correct

4. The word "conservation" in the passage is opposite to 

A. prevention B. pollution C. protection D. preservation

5. Why do we have to conserve resources?

A. Because many resources are limited and non-renewable

B. Because conservation plays an important part in everyone’s life

C. To keep the air from being polluted

         D. To make natural resources renewable 

Read the passage and check (ü) whether the following statements are true (T) or false (F).

Energy makes change; it does things for us. It moves cars along the road and boats over the water. It bakes a cake in the oven and keeps ice frozen in the freezer. It plays our favourite songs on the radio and lights our homes. Energy makes our bodies grow and allows our minds to think. Scientists define energy as the ability to do work. People have learned how to change energy from one from one form to another so that we can do work more easily and live more comfortably.

All forms of energy are stored in different ways, in the energy sources that we use every day. These sources are divided into two groups – renewable and nonrenewable. Renewable energy source is an energy source that can be replenished in a short period of time. Nonrenewable energy source is an energy source that we are using up and cannot recreate in a short period of time.

Renewable energy sources include solar energy, which comes from the Sun and can be turned into electricity and heat. Wind, geothermal energy from inside the Earth, biomass from plants, and hydropower and ocean energy from water are also renewable energy sources.

However, we get most of our energy from nonrenewable energy sources, which include the fossil fuels – oil, natural gas, and coal. They’re called fossil fuels because they were formed over millions and millions of years by the action of heat from the Earth’s core and pressure from rock and soil on the remains of dead plants and animals. Another nonrenewable energy source is the element uranium, whose atoms we split (through a process called nuclear fission) to create heat and ultimately electricity.

Question: Renewable energy can be turned into electricity and heat.

A. True

B. False

Hello students. 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.

Question 4: Non-renewable energy can be generated in a short time.

A. True

B. False

C. Not Given
