Read the passage carefully, then choose the correct answer.

Coal, oil, and natural gas supply modern civilization with most of irs power. However, not only are supplies of these fuels limited, but they are a major source of pollution. Therefore, it's important to improve, explore and develop such alternative energy sources as nuclear, water, solar and wind power. Each of these alternatives, however, has advantages and disadvantages.

Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they create the difficult problenı of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities locnted far from moving water.Wind power is a pollution-free source renewable energy but it cannot be used many parts of the world where there is insufficient wind. Solar power renewable, it does not cause pollution and it does not add the earth's heat load. However, it ia dilficult to coilect and store. Solar power also requir eensive equipnent

Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resoucs wll ensure supplies of clean, affordable energy for humanity's future.

1. Coal, oil and natural gas .............

a. are very great in amount

c. pollute the atmosphere

b. will never be used up

d. supply most of its power

2. Nuclear power plants

a. are difficult to build ..............

c. are very cheap to maintain

b. pollute the atmosphere

d. create the problem of nuclear waste

3. Wind power...............

a. cannot be used in places that has strong wind

b. is never completely used up

c. is a source of pollution

d. cannot replace itself .

4. What is the adyantage of these alternatives?

a. They are environmentally friendly energy sources

b. They are non renewable forms of energy

c. They are all very practical

d. They are inexpensive to exploit

5. From the passage, it can be inferred that to solve our energy problem...................

a. we will have to stop using many of our modern conveniences

b. scientists will have to find one major source of nonpolluting energy

c. scientists will have to find ways to increase our supplies of coal, oil, and gas

d. a combination of conservation and invention will be needed

Are you looking for a cheap. clean, effective source of power that doesn't cause pollution or waste natural resources? Look no further than solar energy from the sun. At present, most of our electricity comes from the use of coal, gas, oil, or nuclear power. This power could be provided by the sun. One percent of the solar energy that reaches the Earth is enough to provide power for the total pollution. Many countries are already using solar energy. Solar panels are placed on the roof of a house and the Sun's energy is used o heat water. The energy can be stored for a number of days, so on cloudy days you can use solar energy. Sweden has an advanced solar energy program. There, all buildings will be heated by solar energy and cars will use solar energy instead of gas by the year 2015.

True or False sentence:

1....................Solar energy can be cheap and clean.

2....................Most of our electricity now comes from nuclear power.

3....................the solar energy that gets to the Earth cannot provide enough power for the world's population.

4....................Solar energy can be used on cloudy days.

5....................All buildings in Sweden will be heated by solar energy in 2050.
