READING PASSAGE 2

You should spend about 20 minutes on Question 14 – 26 which are based on Reading Passage 2.

Photovoltaics on the rooftop

A natural choice for powering the family home

A In the past, urban homeowners have not always had much choice in the way electricity is supplied
to their homes. Now, however, there is a choice, and a rapidly increasing number of households
worldwide are choosing the solar energy option. Solar energy, the conversion of sunlight into
energy, is made possible through the use of 'photovoltaics', which are simple appliances that fit
onto the roof of a house.

B The photovoltaics-powered home remains connected to the power lines, but no storage is required
on-site, only a box of electronics (the inverter) to the interface between the photovoltaics and the
grid network. Figure 1 illustrates the system. During the day, when the home may not be using
much electricity, excess power from the solar array is fed back to the grid, to factories and offices
that need daytime power. At night, power flows the opposite way. The grid network effectively
provides storage. If the demand for electricity is well matched to when the sun shines, solar energy
is especially valuable. This occurs in places like California in the US and Japan, where air-
conditioning loads for offices and factories are large but heating loads for homes are small.

C The first systematic exploration of the use of photovoltaics on homes began in the US during the
1970s. A well-conceived program started with the sitting of a number of residential experiment
stations' at selected locations around the country, representing different climatic zones. These
stations contained a number of 'dummy' houses, each with a different solar-energy system design.
Homes within the communities close to these stations were monitored to see how well their energy
use matched the energy generated by the stations' dummy roofs. A change in US government
priorities in the early 1980s halted this program.

D With the US effort dropping away, the Japanese Sunshine Project came to the fore. A large
residential test station was installed on Rokko Island beginning in 1986. This installation consists of
18 'dummy' homes. Each equipped with its own 2 - 5 kilowatt photovoltaic system (about 20-50
square meters for each system). Some of these simulated homes have their own electrical
appliances inside, such as TV sets, refrigerators and air conditioning units, which switch on and off
under computer control providing a lavish lifestyle for the non-existent occupants. For the other
systems, electronics simulate these household loads. This test station has allowed the technical
issues involved in using photovoltaics within the electricity network to be explored in a systematic
way, under well-controlled test conditions. With no insurmountable problems identified, the
Japanese have used the experience gained from this station to begin their own massive residential
photovoltaics campaign.
E Meanwhile, Germany began a very important '1,000 roof program' in 1990, aimed at installing
photovoltaics on the roofs of 1,000 private homes. Large federal and regional government
subsidies were involved, accounting in most cases for 70% of the total system costs. The program
proved immensely popular, forcing its extension to over 2,000 homes scattered across Germany.
The success of this program stimulated other European countries to launch similar programs.

F Japan's 'one million roof program' was prompted by the experience gained in the Rokko Island test
site and the success of the German 1,000 roof program. The initially quoted aims of the Japanese
New Energy Development Organization were to have 70,000 homes equipped with the
photovoltaics by the year 2000, on the way to 1 million by 2010. The program made a modest start
in 1994, when 539 systems were installed with a government subsidy of 50 percent. Under this
program, entire new suburban developments are using photovoltaics.

G The Japanese initiative in embracing residential photovoltaics on a large scale prompted responses
in both Europe and the US. The European Commission has called for one million solar residential
systems before the year 2010, with 500,000 in Europe and 500,000 in the developing world, to be
subsidised by the Commission. In 1997, a similar one million roof target was announced in the US.
Since then, several other countries including Germany, Italy, the Netherlands and Australia, have
announced their own targets for residential photovoltaics.

H This is good news, not only for the photovoltaic industry, but for everyone concerned with the
environment. The use of fossil fuels to generate electricity is not only costly in financial terms, but
also in terms of environmental damage. Gases produced by the burning of fossil fuels in the
production of electricity are a major contributor to the greenhouse effect. To deal with this problem,
many governments are now proposing stringent targets on the amount of greenhouse gas
emissions permitted. These targets mean that all sources of greenhouse gas emissions including
residential electricity use, will receive closer attention in the future.

I It is likely that in the future, governments will develop building codes that attempt to constrain the
energy demands of new housing. For example, the use of photovoltaics or the equivalent maybe
stipulated to lessen demands on the grid network and hence reduce fossil fuel emissions.
Approvals for building renovations may also be conditional upon taking such energy-saving
measures. If this were to happen, everyone would benefit. Although there is an initial cost in
attaching the system to the rooftop, the householder's outlay is soon compensated with the savings
on energy bills. In addition, everyone living on the planet stands to gain from the more benign
environmental impact.

Residential use of photovoltaics - by day excess power is sent to the grid, and by night power is
supplied to the home.

How should reading be taught?
By Keith Rayner an Barbara R Foorman

A Learning to speak is automatic for almost all children, but learning to read requires elaborate
instruction and conscious effort. Well aware of the difficulties, educators have given a great deal of
thought to how they can best help children learn to read. No single method has triumphed. Indeed,
heated arguments about the most appropriate form of reading instruction continue to polarise the
teaching community.

B Three general approaches have been tried. In one, called whole-word instruction, children learn by rote
how to recognise at a glance a vocabulary of 50 to 100 words. Then they gradually acquire other words,
often through seeing them used over and over again in the context of a story.

Speakers of most languages learn the relationship between letters and the sounds associated with
them (phonemes). That is, children are taught how to use their knowledge of the alphabet to sound out
words. This procedure constitutes a second approach to teaching reading - phonics.

Many schools have adopted a different approach: the whole-language method. The strategy here relies
on the child's experience with language. For example, students are offered engaging books and are
encouraged to guess the words that they do not know by considering the context of the sentence or by
looking for clues in the storyline and illustrations, rather than trying to sound them out.

Many teachers adopted the whole-language approach because of its intuitive appeal. Making reading
fun promises to keep children motivated, and learning to read depends more on what the student does
than on what the teacher does. The presumed benefits of whole-language instruction - and the contrast
to the perceived dullness of phonics - led to its growing acceptance across America during the 1990s,
and a movement away from phonics.

C However, many linguists and psychologists objected strongly to the abandonment of phonics in
American schools. Why was this so? In short, because research had clearly demonstrated that
understanding how letters related to the component sounds in words is critically important in reading.
This conclusion rests, in part, on knowledge of how experienced readers make sense of words on a
page. Advocates of whole-language instruction have argued forcefully that people often derive
meanings directly from print without ever determining the sound of the word. Some psychologists today
accept this view, but most believe that reading is typically a process of rapidly sounding out words
mentally. Compelling evidence for this comes from experiments which show that subjects often confuse
homophones (words that sound the same, such as 'rose' and 'rows'). This supports the idea that
readers convert strings of letters to sounds.
D In order to evaluate different approaches to teaching reading, a number of to experiments have been
carried out, firstly with college students, then with school pupils. Investigators trained English-speaking
college students to read using unfamiliar symbols such as Arabic letters (the phonics approach), while
another group learned entire words associated with certain strings of Arabic letters (whole-word). Then
both groups were required to read a new set of words constructed from the original characters. In
general, readers who were taught the rules of phonics could read many more new words than those
trained with a whole-word procedure.

Classroom studies comparing phonics with either whole-word or whole-language instruction are also
quite illuminating. One particularly persuasive study compared two programmes used in 20 first-grade
classrooms. Half the students were offered traditional reading instruction, which included the use of
phonics drills and applications. The other half were taught using an individualised method that drew
from their experiences with language; these children produced their own booklets of stories and
developed sets of words to be recognised (common components of the whole-language approach). This
study found that the first group scored higher at year's end on tests of reading and comprehension.

E If researchers are so convinced about the need for phonics instruction, why does the debate continue?
Because the controversy is enmeshed in the philosophical differences between traditional and
progressive (or new) approaches, differences that have divided educators for years. The progressives
challenge the results of laboratory tests and classroom studies on the basis of a broad philosophical
scepticism about the values of such research. They champion student-centred learning and teacher
empowerment. Sadly, they fail to realise that these very admirable educational values are equally
consistent with the teaching of phonics.

F If schools of e du cation insisted that would-be reading teachers learned something about the vast
research in linguistics and psychology that bears on reading, their graduates would be more eager to
use phonics and would be prepared to do so effectively. They could allow their pupils to apply the
principles of phonics while reading for pleasure. Using whole-language activities to supplement phonics
instruction certainly helps to make reading fun and meaningful for children, so no one would want to
see such tools discarded. Indeed, recent work has indicated that the combination of literature-based
instruction and phonics is more powerful than either method used alone. Teachers need to strike a
balance. But in doing so, we urge them to remember that reading must be grounded in a firm
understanding of the connections between letters and sounds. Educators who deny this reality are
neglecting decades of research. They are also neglecting the needs of their students.
Questions 32- 36

Do the following statements agree with the information given in Reading Passage 3?

In boxes 32-36 on your answer sheet, write

TRUE if the statement agrees with the information

FALSE if the statement contradicts the information

NOT GIVEN if there is no information on this

32 The whole-language approach relates letters to sounds.


33 Many educators believe the whole-language approach to be the most interesting way to teach
children to read.
34 Research supports the theory that we read without linking words to sounds.
35 Research has shown that the whole-word approach is less effective than the whole-language
approach.
36 Research has shown that phonics is more successful than both the whole-word and whole-
language approaches.
