The following statements list some advantages and disadvantages of various sources of energy. Read and tick () the appropriate box A ( for the advantages ) or D (for the disadvantages ), then compare the results with partner’s A 1.Fossil fuels will be exhausted within a relatively short time 2.Geothermal heat is available only in the few place in the world 3.If the wind does not blow, there is no wind energy 4.Water power provides energy without pollution 5.A nuclear reactor releases radiation which is dangerous to the environment Solar energy is not only plentiful and unlimited but also clean and safe 7.It is expensive to built a dam for hydroelectricity D Task 2: Work in pairs Talk with your friend about the advantages and disadvantages of using each alternative sources of energy , using the suggestions from Task I think that wind power can be an alternative source of energy Why you think so? Some suggestions to express advantages and disadvantages What do you think about? What is your opinion? Asking for your What do you mean that? opinions Why do you think so? How do you feel about? I think/ believe/ feel … In my opinion … Expressing According to … opinions It meant that … I agree/ think so… Express agreements That’s right/ true … It’s a good idea … I don’t think/ I don’t agree/ I disagree … Express Well, It’s not true/ right but … disagreements Sources of energy Advantages Disadvantages Nuclear energy It is unlimited It can be dangerous Geothermal heat It is available It is only available in some places Solar energy Wind power Water power It is not only plentiful and infinite but also clean and safe It is only possible during the day time It is clean and unlimited If the wind doenn’t blow,there is no wind no energy It is clean and unlimited It is expensive to built a dam for hydroelectricity Example : A: I think that wind power can be an alternative sources (1) of energy B: Why you think so? A: Because our major sources of energy are running out while the wind is abundant and unlimited (2) B: I know it is also clean and safe to the environment (3) However, it is not available when there is no wind (4) A: I think that _(1) _ can be an alternative source of energy B: Why you think so? A: Because our major sources of energy are running out while (2) B: I know _(3) However, _(4) _ (1): solar energy (2): solar energy is plentiful and infinite (3): It is also clean and safe to the enviroment (4): It is only possible during the day time A: I think that solar energy can be an alternative sources of energy B: Why you think so? A: Because our major sources of energy are running out while the solar energy is plentiful and infinite B: I know it is also clean and safe to the environment However, it is only possible during the day time A: I think that _(1) _ can be an alternative source of energy B: Why you think so? A: Because our major sources of energy are running out while (2) B: However, _(3) _ (1): nuclear power (2): nuclear power is unlimited (3): It can be very dangerous A nuclear reactor releases radiation which is harmful to the environment A: I think that _(1) _ can be an alternative source of energy B: Why you think so?
