25. B. SPEAKING
26. IV. Ask and answer questions about the advantages and disadvantages of each type of energy sources. Example: A: What type of energy is oil ? B: It is a non-renewable source of energy because it cannot easily be replaced . A: What are its advantages and disadvantages ? B: It can be used to drive machinery, but it also pollutes the environment.
27. Sources of energy Advantages Disadvantages oil/ coal/ natural gas - create energy - harmful (non-renewable) - generate electricity - pollutes the environment - drive machinery - limited/ exhaustible hydro/ water - create electricity -limited because dams can (renewble) - cheap, plentiful, alternative only be built in certain areas Nuclear - provide energy expensive, dangerous (renewable) - clean, abundant Solar - abundant, clean, safe, alternative expensive (renewable) - can be converted into electricity Wind - alternative, clean, safe, not available (renewable) - turn turbines to make electricity Biogas - alternative - harmful (renewable) - pollutes the environment Example: A: What type of energy is oil? B: It is a non-renewable source of energy because it cannot easily be replaced. A: What are its advantages and disadvantages? B: It can be used to drive machinery, but it also pollutes the environment.
28. V. Talk about the advantages and disadvantages of each type of energy sources. Example: Hydro power is a renewable source of energy because it comes from water. It is cheap and plentiful. Unfortunately, dams can only be built in certain areas.
29. You should make your carbon footprint small by - using low energy light bulbs - walking or riding a bike when travelling short distances - using public transport when traveling long distances - using hand fans to keep cool in summer - turning off the lights when leaving a room or going to bed - watching less T.V - only use as much water as you need - .
30. - Learn by heart all new words - practice speaking English at home - do the exercises C1-2 in the workbook (P.33) - Prepare for the Unit 10-part Skills 2
