Number It can be found in only some places of the earth GEOTHERMAL HEAT Number This energy can be very dangerous NUCLEAR ENERGY Number Sailboats couldn’t move without this energy WIND ENERGY Number have no more They will be exhausted within a relatively short time FOSSIL FUELS Number It covers about three quarters (¾ ) of the earth’s surface WATER ENERGY Number Panels are used to create this energy SOLAR ENERGY reactor (n) lò phản ứng radiation (n) phóng xạ dam (n) đập nước enormous (adj) dồi dào, to lớn enormous (adj): Khổng lồ, lớn renewable(adj): phục hồi >< nonrenewable TASK Read and tick the appropriate box A (for the advantages) or D (for the disadvantages) ADVANTAGE (A) A D DISADVANTAGE (D) 1.Fossil fuels will be exhausted within a relatively short time 2.Geothermal heat is available only in the few places 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 TASK Work in pairs, talk with your friend about the advantages and disadvantages of using each source of energy Example: A: I think that wind power can be an alternative sources (1) source of energy 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) advantage B: I know it is also clean and safe to the environment (3) advantage However, it is not available when there is no wind (4) disadvantage Task 2: Talk with your friend about the advantages and disadvantages of using each alternative source of energy A: I think that can be an alternative source of energy B: Why you think so? A: Because our major sources of energy are running out while B: I know that it is but Useful language SOURCES OF ENERGY Nuclear power ADVANTAGES DISADVANTAGE S unlimited plentiful dangerous Water power enormous, expensive Geothermal available heat Solar energy renewable, only in a few places clear and safe clean and safe only possible during the day time Useful language: To express opinions: •I think that … •I believe that … •In my opinion, … •For me, … •If you ask me, … •I feel … Useful language: To express agreement: • That’s right! • I agree with you • I can't agree more • Absolutely! To express disagreemen •I don’t agree with you •I can’t agree with you •You may be right, but … •Don’t you think that … •It’s true, but … Task 2: Talk with your friend about the advantages and disadvantages of using each alternative source of energy newclear power / unlimited./ dangerous A: I think/believe that nuclear power can be an alternative source of energy B: Why you think/ believe so? A: Because our major sources of energy are running out while the nuclear power is unlimitted B: I know However, it can be dangerous Task 2: Talk with your friend about the advantages and disadvantages of using each alternative source of energy wind power / abundant and unlimited / clean and safe to the environment / not available when there is no wind A: I think/believe that wind power can be an alternative sources of energy B: Why you think/ believe so? A: Because our major sources of energy are running outabundant while and the unlimited wind is clean and safe to the environment available when there is no wind B: I know it isnot also However, it is Task 2: Talk with your friend about the advantages and disadvantages of using each alternative source of energy geothermal heat/ abundant / clean and safe to the environment /only possible in few minutes A: I think/believe that geothermal heat can be an alternative source of energy B: Why you think/ believe so? A: Because our major sources of energy are running out while it is abundant B: I know it is also clean and safe to Task 3: Work in groups Make a conversation to express your belief on the increasing use of alternative sources in the future, using the idiea from Task Student A: Give your suggestion of an alternative source of energy (I think/believe that more and more people will use… as a source of energy in the future.) Student B: Ask A for the reason (Why you think/believe so?) Student A: Explain the reason (Because it is unlimited…… ) Student C: Say the disadvantage of that source (But it is expensive and only available during… .) Student D: Express his own opinion (I hope the progress of science and technology will help overcome this problem… .) MHA Task 3: Work in groups Make a conversation to express your belief on the increasing use of alternative sources in the future, using the idiea from Task More and more people / use solar power/ a source of energy/ in the future Why/ think so? because/ available, unlimited & easy to use But it is expensive and we can only have it when there is the sun./ …… I hope that scientists will help overcome… MHA Practice speaking again As much as possible Prepare Listening lesson ... disadvantages of using each source of energy Example: A: I think that wind power can be an alternative sources (1) source of energy of energy B: Why you think so?
