Today there are 700 million English users in the world, and over half of these are nonnative speakers, constituting the largest number of nonnative users of any language in the world.
Africa owes its termite mounds a lot. Trees and shrubs take root in them. Prospectors mine them, looking for specks of gold carried up by termites from hundreds of metres below. And of course, they are a special treat to aardvarks and other insectivores. Now, Africa is paying an offbeat tribute to these towers of mud. The extraordinary Eastgate Building in Harare, Zimbabwe's capital city, is said to be the only one in the world to use the same cooling and heating principles as the termite mound. Termites in Zimbabwe build gigantic mounds inside which they farm a fungus that is their primary food source. This must be kept at exactly 30.5°C, while the temperatures on the African veld outside can range from 1.5°C at night- only just above freezing - to a baking hot 40°C during the day. The termites achieve this remarkable feat by building a system of vents in the mound. Those at the base lead down into chambers cooled by wet mud carried up from water tables far below, and others lead up through a flue to the peak of the mound. By constantly opening and closing these heating and cooling vents over the course of the day the termites succeed in keeping the temperature constant in spite of the wide fluctuations outside. Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air conditioning and virtually no heating. The building - the country's largest commercial and shopping complex - uses less than 10% of the energy of a conventional building its size. These efficiencies translated directly to the bottom line: the Eastgate's owners saved $3.5 million on a $36 million building because an air- conditioning plant didn't have to be imported. These savings were also passed on to tenants: rents are 20% lower than in a new building next door. The complex is actually two buildings linked by bridges across a shady, glass-roofed atrium open to the breezes. Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents. As it rises and warms, it is drawn out via ceiling vents and finally exits through fortyeight brick chimneys. To keep the harsh, high veld sun from heating the interior, no more than 25% of the outside is glass, and all the windows are screened by cement arches that jut out more than a metre. During summer's cool nights, big fans flush air through the building seven times an hour to chill the hollow floors. By day, smaller fans blow two changes of air an hour through the building, to circulate the air which has been in contact with the cool floors. For winter days, there are small heaters in the vents.
D to enable the termites to survive at night 2 Why was Eastgate cheaper to build than a conventional building? A Very few materials were imported. B Its energy consumption was so low. C Its tenants contributed to the costs. D No air conditioners were needed. 3 Why would a building like Eastgate not work efficiently in New York? A Temperature change occurs seasonally rather than daily. B Pollution affects the storage of heat in the atmosphere. C Summer and winter temperatures are too extreme. D Levels of humidity affect cloud coverage. 4 What does Ove Arup's data suggest about Eastgate's temperature control system? A It allows a relatively wide range of temperatures. B The only problems are due to human error. C It functions well for most of the year. D The temperature in the atrium may fall too low. 5 Pearce believes that his building would be improved by A becoming more of a habitat for wildlife. B even closer links with the history of Zimbabwe. C giving people more space to interact with nature. D better protection from harmful organisms.
The accidental rainforest According to ecological theory, rainforests are supposed to develop slowly over millions of years. But now ecologists are being forced to reconsider their ideas When Peter Osbeck, a Swedish priest, stopped off at the mid-Atlantic island of Ascension in 1752 on his way home from China, he wrote of 'a heap of ruinous rocks' with a bare, white mountain in the middle. All it boasted was a couple of dozen species of plant, most of them ferns and some of them unique to the island. And so it might have remained. But in 1843 British plant collector Joseph Hooker made a brief call on his return from Antarctica. Surveying the bare earth, he concluded that the island had suffered some natural calamity that had denuded it of vegetation and triggered a decline in rainfall that was turning the place into a desert. The British Navy, which by then maintained a garrison on the island, was keen to improve the place and asked Hooker's advice. He suggested an ambitious scheme for planting trees and shrubs that would revive rainfall and stimulate a wider ecological recovery. And, perhaps lacking anything else to do, the sailors set to with a will. In 1845, a naval transport ship from Argentina delivered a batch of seedlings. In the following years, more than 200 species of plant arrived from South Africa. From England came 700 packets of seeds, including those of two species that especially liked the place: bamboo and prickly pear. With sailors planting several thousand trees a year, the bare white mountain was soon cloaked in green and renamed Green Mountain, and by the early twentieth century the mountain's slopes were covered with a variety of trees and shrubs from all over the world. Modern ecologists throw up their hands in horror at what they see as Hooker's environmental anarchy. The exotic species wrecked the indigenous ecosystem, squeezing out the island's endemic plants. In fact, Hooker knew well enough what might happen. However, he saw greater benefit in improving rainfall and encouraging more prolific vegetation on the island. But there is a much deeper issue here than the relative benefits of sparse endemic species versus luxuriant imported ones. And as botanist David Wilkinson of Liverpool John
Conservationists have understandable concerns, Wilkinson says. At least four endemic species have gone extinct on Ascension since the exotics started arriving. But in their urgency to protect endemics, ecologists are missing out on the study of a great enigma. 'As you walk through the forest, you see lots of leaves that have had chunks taken out of them by various insects. There are caterpillars and beetles around,' says Wilkinson. 'But where did they come from? Are they endemic or alien? If alien, did they come with the plant on which they feed or discover it on arrival?' Such questions go to the heart of how rainforests happen. The Green Mountain forest holds many secrets. And the irony is that the most artificial rainforest in the world could tell us more about rainforest ecology than any number of natural forests. Do the following statements agree with the information given in Reading Passage 3? In boxes 1-6 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 1 When Peter Osbeck visited Ascension, he found no inhabitants on the island. 2 The natural vegetation on the island contained some species which were found nowhere else. 3 Joseph Hooker assumed that human activity had caused the decline in the island's plant life. 4 British sailors on the island took part in a major tree planting project. 5 Hooker sent details of his planting scheme to a number of different countries. 6 The bamboo and prickly pear seeds sent from England were unsuitable for Ascension. Complete each sentence with the correct ending A-G from the box below. Write the correct letter A-G in boxes 7-10 on your answer sheet.
7 The reason for modern conservationists' concern over Hooker's tree planting programme is that 8 David Wilkinson says the creation of the rainforest in Ascension is important because it shows that 9 Wilkinson says the existence of Ascension's rainforest challenges the theory that 10 Alan Gray questions Wilkinson's theory, claiming that SECTION C: WRITING (20 POINTS) I. Finish the second sentence in such a way that it means exactly the same as the sentence printed before it. (10 pts) A other rainforests may have originally been planted by man. B many of the island's original species were threatened with destruction. C the species in the original rainforest were more successful than the newer arrivals. D rainforests can only develop through a process of slow and complex evolution. E steps should be taken to prevent the destruction of the original ecosystem. F randomly introduced species can coexist together. G the introduced species may have less ecological significance than the original ones.
