14、velopment of PlasticsA When rubber was first commercially produced in Europe during the nineteenth century, it rapidly became a very important commodity, particularly in the fields of transportation and electricity. However, during the twentieth century a number of new synthetic materials, called pl

15、astics, superseded natural rubber in all but a few applications.B Rubber is a polymera compound containing large molecules that are formed by the bonding of many smaller, simpler units, repeated over and over again. The same bonding principlepolymerizationunderlies the creation of a huge range of pl

16、astics by the chemical industry.C The first plastic was developed as a result of a competition in the USA. In the 1860s $10,000 was offered to anybody who could replace ivorysupplies of which were decliningwith something equally good as a material for making billiard balls. The prize was won by John

17、 Wesley Hyatt with a material called celluloid. Celluloid was made by dissolving cellulose, a carbohydrate derived from plants, in a solution of camphor dissolved in ethanol. This new material rapidly found uses in the manufacture of products such as knife handles, detachable collars and cuffs, spec

18、tacle frames and photographic film. Without celluloid, the film industry could never have got off the ground at the end of the 19th century.D Celluloid can be repeatedly softened and reshaped by heat, and is known as a thermoplastic. In 1907, Leo Baekeland, a Belgian chemist working in the USA, inve

19、nted a different kind of plastic, by causing phenol and formaldehyde to react together. Baekeland called the material Bakelite, and it was the first of the thermosetsplastics that can be cast and moulded while hot, but cannot be softened by heat and reshaped once they have set. Bakelite was a good i

20、nsulator, and was resistant to water, acids and moderate heat. With these properties it was soon being used in the manufacture of switches, household items such as knife handles, and electrical components for cars.E Soon chemists began looking for other small molecules that could be strung together

21、to make polymers. In the 1930s British chemists discovered that the gas ethylene would polymerize under heat and pressure to form a thermoplastic they called polythene. Polypropylene followed in the 1950s. Both were used to make bottles, pipes and plastic bags. A small change in the starting materia

22、lreplacing a hydrogen atom in ethylene with a chlorine atomproduced PVC (polyvinyl chloride), a hard, fireproof plastic suitable for drains and gutters. And by adding certain chemicals, a soft form of PVC could be produced, suitable as a substitute for rubber in items such as waterproof clothing. A

23、closely related plastic was Teflon, or PTFE (polytetrafluoroethylene). This had a very low coefficient of friction, making it ideal for bearings, rollers, and non-stick frying pans. Polystyrene, developed during the 1930s in Germany, was a clear, glass-like material, used in food containers, domesti

24、c appliances and toys. Expanded polystyrenea white, rigid foamwas widely used in packaging and insulation. Polyurethanes, also developed in Germany, found uses as adhesives, coatings, andin the form of rigid foamsas insulation materials. They are all produced from chemicals derived from crude oil, w

25、hich contains exactly the same elementscarbon and hydrogenas many plastics.F The first of the man-made fibres, nylon, was also created in the 1930s. Its inventor was a chemist called Wallace Carothers, who worked for the Du Pont company in the USA. He found that under the right conditions, two chemi

26、calshexamethylenediamine and adipic acidwould form a polymer that could be pumped out through holes and then stretched to form long glossy threads that could be woven like silk. Its first use was to make parachutes for the US armed forces in World War . In the post-war years nylon completely replace

27、d silk in the manufacture of stockings. Subsequently many other synthetic fibres joined nylon, including Orion, Acrilan and Terylene. Today most garments are made of a blend of natural fibres, such as cotton and wool, and man-made fibres that make fabrics easier to look after.G The great strength of

28、 plastic is its indestructibility. However, this quality is also something of a drawback: beaches all over the world, even on the remotest islands, are littered with plastic bottles that nothing can destroy. Nor is it very easy to recycle plastics, as different types of plastic are often used in the

29、 same items and call for different treatments. Plastics can be made biodegradable by incorporating into their structure a material such as starch, which is attacked by bacteria and causes the plastic to fall apart. Other materials can be incorporated that gradually decay in sunlightalthough bottles

30、made of such materials have to be stored in the dark, to ensure that they do not disintegrate before they have been used.Do the following statements agree with the information given in Reading Passage 1?In boxes 1-7 on your answer sheet, writeTRUE if the statement agrees;FALSE if the statement disag

35、The Effects of Urban Noise on Bird SpeciesA The growing clamour of cities and roads may be annoying to humans, but for many birds it can mean the difference between life and death. Background noise can mask both the sounds of approaching predators and the alarm calls that warn of danger. They can al

36、so rob individuals of reproductive success by drowning out the songs that male birds use to attract mates and demarcate their territory.B If noise levels continue to rise, it seems inevitable that urban bird life will change dramatically. You can already hear the changes, if you know what to listen

37、out for. One giveaway is birds unexpectedly singing outside their traditional peak times of morning and evening. At these prime times of day, wind noise and turbulence are at their lowest, so sound carries furtherbut not if you factor in the impact of rush-hour traffic. Richard Fuller of the Univers

38、ity of Sheffield in the UK has found that some local robins have abandoned the traditional dawn chorus and taken to singing at night to avoid the daytime din altogether. This shift had previously been attributed to the confusing effects of light pollution, but Fullers analysis reveals that daytime n

39、oise has a much stronger effect: the parts of Sheffield with nocturnal singers were an order of magnitude noisier by day than other areas of the city.C It remains to be seen whether singing at night is a successful way to combat noise pollution. It is not the only option, however. Nightingales, when

40、 not singing at night, have opted for an approach that seems at odds with their delicate melodiesthey simply shout louder. When Henrik Brumm, at the University of St. Andrews in the UK, recorded nightingales singing between 5 am and 10 am he found that those in Berlin sang up to 14 decibels louder t

41、han their forest counterparts, achieving volumes of up to 95 decibelsenough to send humans reaching for ear protection. The loudness of their vocals was proportional to the level of background noise, with birds singing particularly loudly on weekday mornings.D Changes in the timing or volume of song

42、s are fairly obvious solutions to the problem, but some songbirds have taken a more subtle approach. Urban noise is particularly loud at low frequencies between about 1 and 3 kilohertz. By avoiding these frequencies, birds can make their songs more audible. Blackbirds, song sparrows and house finche

43、s have adapted in this way, but the most well studied practitioner is the great tit. For the past five years Hans Slabbekoom, of Leiden University in the Netherlands, has analysed the ways in which great tits deal with noisy cities. He found that those inhabiting noisier parts of Leiden sing melodie

44、s with higher minimum frequencies than those in quieter areas of the city. When he looked at populations of great tits in 10 European cities, including London, Pahs and Amsterdam, he found that every one of them sang higher-pitched tunes than their forest-dwelling counterparts, raising the minimum f

45、requency by 200 hertz on average, to around 3,500 hertz.E The ability to change ones tune is a valuable asset in the growing urban hubbub. Unlike some birds that learn their entire repertoire while in the nest, great tits, song sparrows and others regularly modify their songs throughout their lifetime. They have far more tunes than they require and select different songs depending on the context. By monitoring which songs work best in a particular situation, individuals can learn fro
