UNIT 11: SOURCES OF ENERGY Gas Coal Grass Sun Ocean Land VOCABULARY Renewable : /ri'nju:əbl/ (adj): Có thể phục hồi lại >< non – renewable (adj) Renewable energy sources Non – renewable energy sources Reactor: /ri:'ỉktə/ (n) Lò phản ứng A nuclear reactor Radiation /reidi'eiʃn/ (n): Bức xạ Example: A nuclear reactor releases radiation which is dangerous to environment Hydroelectricity /ˌhaɪdrəʊɪˌlekˈtrɪsəti/ (n): thủy điện Hydroelectric energy is made by moving water Vocabulary Renewable : /ri'nju:əbl/ (adj) :Có thể phục hồi lại >< non – renewable (adj) Reactor: /ri:'ỉktə/ (n) : Lò phản ứng Radiation /reidi'eiʃn/ (n): Bức xạ Hydroelectricity: /ˌhaɪdrəʊɪˌlekˈtrɪsəti/ (n): thủy điện ACTIVITY Task 1: Decide whether the statements are the advantages (A) or disadvantages (D) of various sources of energy 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 ACTIVITY Available power Guessing the missing words abundant running out clean and safe wind unlimited wind A: I think that wind power can be an alternative sources (1) of energy B: Why you think/ believe so? A: Because our major sources of energy are running out (2) While the wind is abundant and unlimited (3) (4) B: I know it is also clean and safe to the environment (5) However, it is not available when there is no wind (6) Some suggestions to express advantages and disadvantages Asking for your opinions What you think about?
