    Q1,2

    The writer mentions a number of facts relating to alternative power sources.

    Which TWO of the following facts are mentioned?

    A. International co-operation has yet to result in the large scale implementation and effective use of alternative power sources.

    B. One alternative energy source in particular will have a great impact in the years to come.

    C. A side-effect of one of these forms of energy is the production of chemical waste.

    D. Expense is the main factor that is an obstacle to developing one of these forms of energy

    E. Approximately one in five US homes will be using one of these forms of energy within twenty years.

    F. One attraction of these forms of energy in general is the relatively low production costs.

    Since 1840, cars with the refrigerating system had been utilised to deliver and distribute milk and butter

    C

    Biomass is renewable energy that is produced from organic matter. Biomass fuels include wood, forest and mill residues, animal waste, grains, agricultural crops, and aquatic plants. These materials are used as fuel to heat water for steam or processed into liquids and gases, which can be burned to do the same thing. With more use of biomass at lower production costs and better technology, the United States could generate as much as four-and-a-half times more biopower by 2020. It is estimated that biomass will have the largest increase among renewable energy sources, rising by 80 percent and reaching 65.7 billion KW in 2020.

    H

    Fuel cells are electrochemical devices that produce electricity through a chemical reaction. Fuel cells are rechargeable, contain no moving parts, are clean, and produce no noise. Scientists are exploring ways that they could be used as a power source for nearly exhaust-free automobiles and how they can be used as electricity-generating plants. The high cost of manufacturing fuel cells has prevented the mass use of this valuable energy source.


    Note:

    - The answer for Qs 1 can be found in paragraph C, H.

    - First of all, you should look at option B in the Qs with the key phrase ‘in the years to come’. It means something will happen in the future. Look at paragraph C, we’ve got the number ‘2020’ which refers to the future. Moreover, ‘great impact’ in the Qs can be found in the red highlight sentences in paragraph C.

    - Secondly, you should look at the grey highlight phrase in option D ‘expense’, which has been paraphrased to ‘the high cost of…’ in paragraph H. The word ‘obstacle’ in option D has the same meaning with the phrase ‘has prevented’; the word ‘developing’ in option D can have a different expression by using the phrase ‘ the mass use of…’

    - Considering every detail in the question and some sentences in paragraph C and H, we can conclude the answer for question 1,2

    => Hence, the answer is B, D

Questions 3-4

Choose the correct letter A, B, C or D.

Q3:

Geothermal energy is produced by

A. heating the air below the surface of the ground.

B. employing the force of falling water.

C. extracting water or steam from beneath the earth’s surface.

D. using the earth’s natural electricity.

D

Geothermal energy uses heat from within the earth. Wells are drilled into geothermal reservoirs to bring the hot water or steam to the surface. The steam then drives a turbine-generator to generate electricity in geothermal plants. In some places this heat is used directly to heat homes and greenhouses, or to provide process heat for businesses or industries. Reykjavik, Iceland, is heated by geothermal energy. Most geothermal resources are concentrated in the western part of the United States. Geothermal heat pumps use shallow ground energy to heat and cool homes, and this technique can be employed almost anywhere. With technological improvements much more power could lie generated from hydrothermal resources. Scientists have been experimenting by pumping water into the hot dry rock that is 3-6 miles below the earth’s surface for use in geothermal power plants

READING PASSAGE 1

You should spend about 20 minutes on Questions 1 -13, which are based on Reading Passage 1 below.

ALTERNATIVE ENERGY SOURCES

A

There are many reasons why we are looking towards alternative energy sources. With many countries signing the Kyoto Treaty, efforts to reduce pollutants and greenhouse gases are a primary focus in today’s culture. Alternative, or renewable, energy sources show significant promise in helping to reduce the amount of toxins that are byproducts of energy use. Not only do they protect against harmful by-products, but using alternative energy helps to preserve many of the natural resources that we currently use as sources of energy. To understand how alternative energy use can help preserve the delicate ecological balance of the planet, and help us conserve the non-renewable energy sources like fossil fuels, it is important to know what types of alternative energy are out there.

B

Alternative energy sources are resources that are constantly replaced and are usually less polluting. They are not the result of the burning of fossil fuels or splitting of atoms. The use of renewable energy is contributing to our energy supply. Some alternative energy sources are: biomass energy, geothermal energy, hydroelectric power, solar power, wind power, fuel cells, ocean thermal energy conversion, tidal energy, and wave energy.

C

Biomass is renewable energy that is produced from organic matter. Biomass fuels include wood, forest and mill residues, animal waste, grains, agricultural crops, and aquatic plants. These materials are used as fuel to heat water for steam or processed into liquids and gases, which can be burned to do the same thing. With more use of biomass at lower production costs and better technology, the United States could generate as much as four-and-a-half times more biopower by 2020. It is estimated that biomass will have the largest increase among renewable energy sources, rising by 80 percent and reaching 65.7 billion KW in 2020.

D

Geothermal energy uses heat from within the earth. Wells are drilled into geothermal reservoirs to bring the hot water or steam to the surface. The steam then drives a turbine-generator to generate electricity in geothermal plants. In some places this heat is used directly to heat homes and greenhouses, or to provide process heat for businesses or industries. Reykjavik, Iceland, is heated by geothermal energy. Most geothermal resources are concentrated in the western part of the United States. Geothermal heat pumps use shallow ground energy to heat and cool homes, and this technique can be employed almost anywhere. With technological improvements much more power could lie generated from hydrothermal resources. Scientists have been experimenting by pumping water into the hot dry rock that is 3-6 miles below the earth’s surface for use in geothermal power plants.

E

Hydroelectric (hydropower) energy employs the force of falling water to drive turbine-generators to produce electricity. Hydropower produces more electricity than any other alternative energy source. It has been estimated that hydroelectric power will decline from 389 billion KW in the US in 1999 to 298 billion KW in 2020. This decline is expected because most of the best sites for hydropower have already been developed and because of concerns about the adverse impact that large-scale hydroelectric facilities may have on the environment.

F

Solar energy is generated without a turbine or electromagnet. Special panels of photovoltaic cells capture light from the sun and convert it directly into electricity. The electricity is stored in a battery. Solar energy can also be used to directly heat water for domestic use (solar thermal technology). The domestic photovoltaic (PV) industry could provide up to 15% of new US peak electricity capacity that is expected to be required in 2020.

G

Wind energy can be used to produce electricity. As wind passes through the blades of a windmill, the blades spin. The shaft that is attached to the blades turns and powers a pump or turns a generator to produce electricity. Electricity is then stored in batteries. The speed of the wind and the size of the blades determine how much energy can be produced. Wind energy is more efficient in windier parts of the country. Most wind power is produced from wind farms — large groups of turbines located in consistently windy locations. Wind, used as a fuel, is free and non-polluting and produces no emissions or chemical wastes. Wind-powered electricity is gaining in popularity.

H

Fuel cells are electrochemical devices that produce electricity through a chemical reaction. Fuel cells are rechargeable, contain no moving parts, are clean, and produce no noise. Scientists are exploring ways that they could be used as a power source for nearly exhaust-free automobiles and how they can be used as electricity-generating plants. The high cost of manufacturing fuel cells has prevented the mass use of this valuable energy source.

I

Ocean sources; Oceans, which cover more than 70% of the earth, contain both thermal energy from the sun’s heat and mechanical energy from the tides and waves. Ocean thermal energy conversion (OTEC) converts solar radiation to electric power. OTEC power plants use the difference in temperature between warm surface waters heated by the sun and colder waters found at ocean depths to generate electricity. The power of tides can also be harnessed to produce electricity. Tidal energy works by harnessing the power of changing tides but it needs large tidal differences. The tidal process utilises the natural motion of the tides to fill reservoirs, which are then slowly discharged through electricity-producing turbines. Wave energy conversion extracts energy from surface waves, from pressure fluctuations below the water surface, or from the full wave. Wave energy also uses the interaction of winds with the ocean surface. This technology is still in the exploratory phase in the United States.
