<span class='text_page_counter'>(14)</span> Task 1: The words in the box all appear in the passage. Fill each blank with a suitable word.(Use a dictionary when necessary) alternativelimited energy released exhausted 1 . Six hundred balloons were ______________ at the ceremony . 2 . They are looking for _______________ methods of making it . 3 . People use ________________ to run machines , heat and cool their homes . 4 . The food in the restaurant is cheap , but the choice is rather_________________ . 5 . Fuel supplies are nearly_________________ ..

<span class='text_page_counter'>(15)</span> TASK 2: Scan the passage and write down the advantage (s) and disadvantage (s) of each alternative source ofenergy energy. Sources of Advantage(s) Disadvantage(s) Nuclear power Geothermal heat Wind power Water power.

<span class='text_page_counter'>(16)</span> Paragraph 2 One alternative source is nuclear energy Nuclear. energy can provide enough electricity for the world’s needs for hundreds of years, but it can be very dangerous. Another alternative source of energy is geothermal heat, which comes from deep inside the earth. Scientists use this heat to make energy. However, this energy is available only in a few places in the world.. Sources of energy Nuclear energy Geothermal heat. Advantage(s). Disadvantage(s).

<span class='text_page_counter'>(17)</span> Correct Paragraph 2 Nuclear energy can provide enough electricity for the world’s needs for hundreds of years, but it can be very dangerous. Another alternative source of energy is geothermal heat, which comes from deep inside the earth. Scientists use this heat to make energy. However, this energy is available only in a few places in the world.. Sources of energy. Advantage(s). Nuclear energy. It’s plentiful. Geothermal heat. It is available. Disadvantage(s) It can be very dangerous available in only a few places.

<span class='text_page_counter'>(18)</span> Paragraph 3 The sun, water, and the wind are other alternative sources of energy The wind turns windmills and moves sailboats. It is a clean source of energy, and there is lots of it. Unfortunately, if the wind does not blow, there is no wind energy. When water moves from a high place to a lower place, it makes energy. This energy is used to create electricity. Water power gives energy without pollution. However, people have to build dams to use this energy. And dams cost a lot of money, so water energy is expensive. Sources of Advantage(s) Disadvantage(s) energy wind power water power.

Disadvantage(s). wind power. It’s clean, plentiful, infinite. water power. It’s clean, plentiful, infinite. If the wind does not blow, there is no wind energy. expensive.

<span class='text_page_counter'>(20)</span> Paragraph 4 The sun releases large amounts of. energy every day. This energy can be changed into electricity . Many countries use solar energy for their daily life. Solar panels on the roofs of houses can create enough energy to heat or cool an entire house. Solar energy is not only plentiful and infinite but also clean and safe. Sources of energy Solar energy. Advantage(s). Disadvantage(s).

<span class='text_page_counter'>(21)</span> Correct Paragraph 4. Paragraph 4 The sun releases large amounts. of energy every day. Solar energy is not only plentiful and infinite but also clean and safe. Sources of Advantage(s) energy Solar energy clean,safe, plentiful, infinite. Disadvantage(s) only possible on the day time.
