The International English Language Testing System (IELTS) is
a test of English language proficiency, developed by the University of Cambridge
Local Examinations Syndicate. IELTS is now accepted as evidence of a prospective
student’s level of English by most universities in English speaking
countries.
There are two different IELTS tests
that you can do: Academic and General. The following information will deal only
with the Academic test as this is the test used for university
entrance.
IELTS is not a test that you can
pass or fail. Your assessment will be reported according to a scale from bands
one to nine. You will need to contact the university you wish to enter to find
out the IELTS score they require for entry into your chosen course. Band one
indicates that you have virtually no English at all. Band nine is native speaker
proficiency. Universities in Australia typically require a band score of between
6 and 7.
The test questions and tasks have been designed to
reflect the general interests of people from an educated background. You will
therefore not be required to have any specialist knowledge.
The test has four components – Reading, Writing,
Listening, Speaking. You will receive a band score for each component as well as
a global band score. |

Prompted by the oil
crises of the 1970s, a wind-power industry flourished briefly in the United
States. But then world oil prices dropped, and funding for research into
renewable energy was cut. By the mid 1980s US interest in wind energy as a
large-scale source of energy had almost disappeared. The development of wind
power at this time suffered not only from badly designed equipment, but also
from poor long-term planning, economic projections that were too optimistic and
the difficulty of finding suitable locations for the wind turbines.
Only now are
technological advances beginning to offer hope that wind power will come to be
accepted as a reliable and important source of electricity. There have been
significant successes in California, in particular, where wind farms now have a
capacity of 1500 megawatts, comparable to a large nuclear or fossil-fuelled
power station, and produce 1.5 per cent of the state’s electricity.
Nevertheless, in the US, the image of wind power is still distorted by
early failures. One of the most persistent criticisms is that wind power is not
a significant energy resource. Researchers at the Battelle Northwest Laboratory,
however, estimate that today wind turbine technology could supply 20 per cent of
the electrical power the country needs. As a local resource, wind power has even
greater potential. Minnesota’s energy commission calculates that a wind farm on
one of the state’s south western ridges could supply almost all that state’s
electricity. North Dakota alone has enough sites suitable for wind farms to
supply more than a third of all electricity consumed in the continental
US.
The
prevailing notion that wind power is too costly results largely from early
research which focused on turbines with huge blades that stood hundreds of
metres tall. These machines were not designed for ease of production or
maintenance, and they were enormously expensive. Because the major factors
influencing the overall cost of wind power are the cost of the turbine and its
supporting systems, including land, as well as operating and maintenance costs,
it is hardly surprising that it was thought at the time that wind energy could
not be supplied at a commercially competitive price. More recent developments
such as those seen on California wind farms have dramatically changed the
economic picture for wind energy. These systems, like installations in Hawaii
and several European countries, have benefited from the economies of scale that
come through standardised manufacturing and purchasing. The result has been a
dramatic drop in capital costs: the installed cost of new wind turbines stood at
$1000 per kilowatt in 1993, down from about $4000 per kilowatt in 1980, and
continues to fall.
Design
improvements and more efficient maintenance programs for large numbers of
turbines have reduced operating costs as well. The cost of electricity delivered
by wind farm turbines has decreased from about 30 cents per kilowatt-hour to
between 7 and 9 cents, which is generally less than the cost of electricity from
conventional power stations. Reliability has also improved dramatically. The
latest turbines run more than 95 per cent of the time, compared with around 60
per cent in the early 1980s. Another misconception is that improved designs are
needed to make wind power feasible. Out of the numerous wind turbine designs
proposed or built by inventors or developers, the propeller-blade type, which is
based on detailed analytical models as well as extensive experimental data, has
emerged as predominant among the more than 20,000 machines now in commercial
operation world-wide. Like the gas-driven turbines that power jet aircraft,
these are sophisticated pieces of rotating machinery. They are already highly
efficient, and there is no reason to believe that other configurations will
produce major benefits. Like other ways of generating electricity, wind power
does not leave the environment entirely unharmed. There are many potential
problems, ranging from interference with telecommunications to impact on
wildlife and natural habitats. But these effects must be balanced against those
associated with other forms of electricity generation. Conventional power
stations impose hidden costs on society, such as the control of air pollution,
the management of nuclear waste and global warming. As wind power has been
ignored in the US over the past few years, expertise and commercial exploitation
in the field have shifted to Europe. The European Union spends 10 times as much
as the US government on research and development of wind energy. It estimates
that at least 10 per cent of Europe’s electrical power could be supplied by
land-based wind-turbines using current technology. Indeed, according to the
American Wind Energy Association, an independent organisation based in
Washington, Denmark, Britain, Spain and the Netherlands will each surpass the US
in the generating capacity of wind turbines installed during the rest of the
decade.

SPRING IS IN THE
AIR!
Welcome to our Spring
Daybreak programme which continues the tradition of offering unbeatable value
for money daytrips and tours. All the excursions in this brochure will be
operated by Premier Travel Services Limited or Millers Coaches; both companies
are part of the CHL Group, owners of Cambridge's Cambus fleet.
WE'RE PROUD OF
OUR TRADITION
Premier was established
in 1936; the Company now offers the highest standards of coaching in today's
competitive operating environment. Millers has an enviable reputation stretching
back over the past 20 years, offering value for money coach services at
realistic prices. We've travelled a long way since our early days of pre-war
seaside trips. Now our fleet of 50 modern coaches (few are more than five years
old) operate throughout Britain and Europe but we're pleased still to maintain
the high standards of quality and service, the trademark of our founders nearly
sixty years ago.
EXCLUSIVE
FEATURES
Admission

YOUR QUESTIONS
ANSWERED
Do I need to
book? Booking in advance is
strongly recommended as all Daybreak tours are subject to demand. Subject to
availability, stand-by tickets can be purchased from the driver.
What
time does the coach leave? The coach departs from
Cambridge Drummer Street (Bay 12, adjacent to public toilets) at the time shown.
There are many additional joining points indicated by departure codes in the
brochure. If you are joining at one of our less popular joining points, you will
be advised of your pick up time (normally by telephone) not less than 48 hours
before departure. In this way, we can minimise the length of pick-up routes and
reduce journey times for the majority of passengers.
What
time do we get back? An approximate return time is
shown for each excursion. The times shown serve as a guide, but road conditions
can sometimes cause delay. If your arrival will be later than advertised, your
driver will try to allow for a telephone call during the return
journey.
Where
can I board the coach? All the Daybreaks in the
brochure leave from Cambridge Drummer Street (Bay 12, adjacent to public
toilets) at the time shown. Many Daybreaks offer additional pick-ups for
pre-booked passengers within Cambridge and the surrounding area. This facility
must be requested at the time of booking. |
