LISTENING, page 120 A Lisa says:' the technology is improving all the time which means that even the slightest gusts of wind can generate electricity' She also mentions off­ shore farms (answer B): ' there is big investment in off­ shore wind farms, which are much more reliable; but it doesn't mean that only off-shore farms are reliable C While talking about the Romanian wind farm and its capacity, the presenter supposes that it is less effective than the London site's because the wind at sea is stronger (the London site is 'off-shore; which means not on land.The Romanian site is 'on-shore') Lisa agrees A Lisa says: 'as the price of building wind farms comes down further and the efficiency of the turbines goes up, it is hoped that countries will continue to replace fossil fuel power stations with cheaper, cleaner wind farms' She sounds hopeful and positive about this issue By using the phrase it is hoped that she's expressing the idea that other people are also positive about the future, not just her Open task �2.07 IHMi+J•tl Love them or hate them, huge wind turbines are becoming a more frequent sight along our motorways Along with solar panels, they are an important source of renewable energy But how effective are wind farms at providing the energy we need? Joining me to discuss this Answer C •ttiHfu.i► �2.08 IIR44t+Jtf:t • Presenter: Love them or hate them, huge wind turbines are becoming a more frequent sight along our motorways Along with solar panels, they are an important source of renewable energy But how effective are wind farms at providing the energy we need? Joining me to discuss this is Lisa Baum, a renewable energy expert Lisa, is wind power the future Lisa: I very much think it is.There are so many benefits to wind It's so much cleaner than gas and safer than nuclear.Wind farms are becoming cheaper to build and more efficient to run, making them better alternatives to gas or nuclear European countries are leading the way Germany already gets over ten percent of its energy from wind power and many EU countries will have already reached their wind power targets by 2020 Presenter: But I've read wind power is unreliable What happens when the wind doesn't blow? Lisa: Obviously, that is an issue But the technology is improving all the time which means that even the slightest gusts of wind can generate electricity Also, there is big investment in off-shore wind farms, which are much more reliable.The largest off-shore wind farm is in the UK and there are 175 wind turbine' producing 630 megawatts of electricity Presenter: That sounds impressive Lisa: Well, believe it or not, the biggest on-shore wind farm in Europe is even bigger 240 wind turbines on a 110-kilometre site near the Black Sea in Romania But despite there being 65 more wind turbines, its capacity is smaller than the London site's Presenter: Because the wind at sea is stronger? Lisa: Exactly Presenter: So, what does the future hold? Lisa: Well, as the price of building wind farms comes down further and the efficiency of t1e turbines goes up, it is hoped that countries will continue to replace fossil fuel power stations with cheaper, cleaner wind farms Presenter: Thank you for joining us Lisa: My pleasure 52 Unit 12 B The presenter asks: 'But how effective are wind farms at providing the energy we need?' and then says that he will be discussing this with Lisa Baum A Lisa says: 'Germany already gets over ten percent of its energy from wind power '.We've already heard that wind power is a way of producing renewable energy 41f 2c 3b 4a Se 6d Open task USE OF ENGLISH, page 121 Grammar reference, pages 155 -156 1 could might can't may must Could might won't 1b C e a 1B D B C 4 d C Although all options are -ing forms, living is the best collocation with a greener life B We use the phrasal verb pick up, which means 'to collect; when we talk about removing litter (rubbish) from the streets.The other prepositions don't make sense here A Deals and works can both be used with the preposition with, but we talk about dealing with questions, not working with questions D Although all the options grammatically fit the space, only think makes sense here as the sentence is about people's opinions, not things that they know are true A The word proves in the sentence before the space suggests that the main idea is about what is true or not true Right (answer B) has a very similar meaning, but it's more about what is morally good or acceptable, while true is usually connected with facts D The context of the sentence 'how to reduce electricity and water use without making our lives ' suggests that we have to use an adjective with a negative meaning Easier and better have a positive meaning, while further does not make sense
