Is our major source of energy limited ? Why / why not ? How many sources of energy are mentioned in the text ? What are they ? Which source of energy you think has the most potential? Complete the summary of the reading passage by filling each blank with a suitable word from the box one environment energy unlimited limited alternative sources fuels We need energy to live and work Our major source of energy is oil Oil is (2)… (1) ……… one kind of fossil fuel The limited amount of fossil (3) fuels … in the world is (4) ……… Therefore, we must save it, and at the same time, we must find new sources of energy Geothermal heat and alternative sources of energy nuclear power are (5)… ………… They can give us electricity Other alternative (6) sources ……………are the sun, waves and water These unlimited and available but sources are not only (7)…………… environment People also clean and safe for the (8)………………… should develop and use them more and more in the future • Write the answers into notebooks • Prepare Unit 11 B : SPEAKING What is our major source of energy ? Our major source of energy comes from fossil fuels :2 You’ve just lost half of your points! You are unlucky! Is our major source of energy limited ? Why / why not ? Yes, it is Because power demand is increasing very rapidly , fossil fuels will be exhausted within a relatively short time How many sources of energy are mentioned in the text ? What are they ? Five sources of energy are mentioned in the text They are : nuclear power , solar energy , water power , wind power , geothermal heat Which source of energy you think has the most potential? I think solar energy is the most potential X Lucky number! ... passage and write down the advantage (s) and disadvantage (s) of each alternative source of energy Sources of energy Nuclear power Solar energy Advantage(s) It’s unlimited It’s not only plentiful... environment energy unlimited limited alternative sources fuels We need energy to live and work Our major source of energy is oil Oil is (2)… (1) ……… one kind of fossil fuel The limited amount of fossil... time, we must find new sources of energy Geothermal heat and alternative sources of energy nuclear power are (5)… ………… They can give us electricity Other alternative (6) sources ……………are the sun,
