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.

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

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 7
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.

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.

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.
