Title: an Alternative Approach of Farming in Honduras 洪都拉斯新农耕方法

Question types: 段落信息匹配题6题摘要填空题5题

多选题2题

文章内容回顾关于洪都拉斯农业耕种。过去人们采用刀耕火种的方式:把一片树林砍伐成平地,半年以后再在上面种植植物,这就造成了土地肥力下降,所以人们就不得不再砍伐新的树林来开辟耕地。后来政府推广了一种新的种植方法:在原耕地上种一种能快速生长的树。优点是不用经常照料,之后把树的叶子砍下来作为肥料,一段时间之后在堆肥的地方挖洞种庄稼进去。

题型难度分析14-19 段落信息匹配题

14. Why does the previous mode of farming need constantly changing places? 选:A(村庄周围的土地资源早已枯竭,农民不得不长途跋涉2-3小时到山上去工作)

15. The new working mode does not care who the operator is. 选:F (农业可以让所有家庭成员都参与,并解释了为什么)

16. a kind of material that must be added 选:F (inexpensive nitrogen, cook fuel)

17. how the new mode of farming (IAC) imitates the process of forest 选:D(一个人发明了这种农耕方式,并说明在自然状态下树叶自然掉落在地上以后可以为土壤增加养分)

18. why farmers have to continue the unattainable farming on the infertile land 选:B(因为土地稀缺)

19. a description of the cost of using this new approach of planting crops 选:C(需要分离出一部分土地来种树,并且要等树长成,但不会影响农民的生计)

20-24 摘要题填空

The government and Dr. Hans promoted the approach of shifting agriculture and recycling of fertilizers without too much 20. attention, because it is lack of 21. light so that weeds and grass will not survive. The pruned branches would be put on the ground to form a thick layer of decomposing 22. leaves. The crops would get nutrients from the 23. holes. This approach poses no risk on farmers’ 24. livelihood. 25-26 多选题

Mechanism of Linguistic Change

The changes that have caused the most disagreement are those in pronunciation. We have various sources of evidence for the pronunciations of earlier times, such as the spellings, the treatment of words borrowed from other languages or borrowed by them, the descriptions of contemporary grammarians and spelling-reformers, and the modern pronunciations in all the languages and dialects concerned. From the middle of the sixteenth century, there are in England writers who attempt to describe the position of the speech-organs for the production of English phonemes, and who invent what are in effect systems of phonetic symbols. These various kind of evidence, combined with a knowledge of the mechanisms of speech-production, can often give us a very good idea of the pronunciation of an earlier age, though absolute certainty is never possible.

When we study the pronunciation of a language over any period of a few generations or more, we find there are always large-scale regularities in the changes: for example, over a certain period of time, just about all the long [a:] vowels in a language may change into long [e:] vowels,or all the [b] consonants in a certain position (for example at the end of a word) may change into [p] consonants. Such regular changes are often called sound laws. There are no universal sound laws (even though sound laws often reflect universal tendencies), but simply particular sound laws for one given language (or dialect) at one given period.

It is also possible that fashion plays a part in the process of change. It certainly plays a part in the spread of change: one person imitates

another, and people with the most prestige are most likely to be imitated, so that a change that takes place in one social group may be imitated (more or less accurately) by speakers in another group. When a social group goes up or down in the world, its pronunciation may gain or lose prestige. It is said that, after the Russian Revolution of 1917, the upper-class pronunciation of Russian, which had formerly been considered desirable, became on the contrary an undesirable kind of accent to have, so that people tried to disguise it. Some of the changes in accepted English pronunciation in the seventeenth and eighteenth centuries have been shown to consist in the replacement of one style of pronunciation by another style already existing, and it is likely that such substitutions were a result of the great social changes of the period: the increased power and wealth of the middle classes, and their steady infiltration upwards into the ranks of the landed gentry, probably carried elements of middle-class pronunciation into upper-class speech.

A less specific variant of the argument is that the imitation of children is imperfect: they copy their parents’ speech, but never reproduce it exactly. This is true, but it is also true that such deviations from adult speech are usually corrected in later childhood. Perhaps it is more significant that even adults show a certain amount of random variation in their pronunciation of a given phoneme, even if the phonetic context is kept unchanged. This, however, cannot explain changes in pronunciation unless it can be shown that there is some systematic trend in the failures of imitation: if they are merely random deviations they will cancel one another out and there will be no net change in the language.

One such force which is often invoked is the principle of ease, or minimization of effort. The change from fussy to fuzzy would be an example of assimilation, which is a very common kind of change. Assimilation is the changing of a sound under the influence of a neighbouring one. For example, the word scant was once skamt, but the /m/ has been changed to /n/ under the influence of the following /t/. Greater efficiency has hereby been achieved, because /n/ and /t/ are articulated in the same place (with the tip of the tongue against the teeth-ridge), whereas /m/ is articulated elsewhere (with the two lips). So the place of articulation of the nasal consonant has been changed to conform with that of the following plosive. A more recent example of the same kind of thing is the common pronunciation of football as foopball.

Assimilation is not the only way in which we change our pronunciation

in order to increase efficiency. It is very common for consonants to be lost at the end of a word: in Middle English, word-final [-n] was often lost in unstressed syllables, so that baken ‘to bake’ changed from [ba:k?n] to [ba:k?],and later to [ba:k]. Consonant-clusters are often simplified. At one time there was a [t] in words like castle and Christmas, and an initial [k] in words like knight and know. Sometimes a whole syllable is dropped out when two successive syllables begin with the same consonant (haplology): a recent example is temporary, which in Britain is often pronounced as if it were tempory.

2015年雅思阅读模拟试题及答案解析三

Time to cool it 1 REFRIGERATORS are the epitome of clunky technology: solid, reliable and just a little bit dull. They have not changed much over the past century, but then they have not needed to. They are based on a robust and effective idea--draw heat from the thing you want to cool by evaporating a liquid next to it, and then dump that heat by pumping the vapour elsewhere and condensing it. This method of pumping heat from one place to another served mankind well when refrigerators' main jobs were preserving food and, as air conditioners, cooling buildings. Today's high-tech world, however, demands high-tech refrigeration. Heat pumps are no longer up to the job. The search is on for something to replace them. 2 One set of candidates are known as paraelectric materials. These act like batteries when they undergo a temperature change: attach electrodes to them and they generate a current. This effect is used in infra-red cameras. An array of tiny pieces of paraelectric material can sense the heat radiated by, for example, a person, and the pattern of the array's electrical outputs can then be used to construct an image. But until recently no one had bothered much with the inverse of this process. That inverse exists, however. Apply an appropriate current to a paraelectric material and it will cool down. 3 Someone who is looking at this inverse effect is Alex Mischenko, of Cambridge University. Using commercially available paraelectric film, he and his colleagues have generated temperature drops five times bigger than any previously recorded. That may be enough to change the phenomenon from a laboratory curiosity to something with commercial applications. 4 As to what those applications might be, Dr Mischenko is still a little hazy. He has, nevertheless, set up a company to pursue them. He foresees putting his discovery to use in more efficient domestic fridges and air conditioners. The real money, though, may be in cooling computers. 5 Gadgets containing microprocessors have been getting hotter for a long time. One consequence of Moore's Law, which describes the doubling of the number of transistors on a chip every 18 months, is that the amount of heat produced doubles as well. In fact, it more than doubles, because besides increasing in number,the components are getting faster. Heat is released every time a logical operation is performed inside a microprocessor, so the faster the processor is, the more heat it generates. Doubling the frequency quadruples the heat output. And the frequency has doubled a lot. The first Pentium chips sold by Dr Moore's company,Intel, in 1993, ran at 60m cycles a second. The Pentium 4--the last "single-core" desktop processor--clocked up 3.2 billion cycles a second. 6 Disposing of this heat is a big obstruction to further miniaturisation and higher speeds. The innards of a desktop computer commonly hit 80℃. At 85℃, they

1. A European spacecraft took off today to spearhead the search for another "Earth" among the stars. 2. The Corot space telescope blasted off aboard a Russian Soyuz rocket from the Baikonur cosmodrome in Kazakhstan shortly after 2.20pm. 3. Corot, short for convection rotation and planetary transits, is the first instrument capable of finding small rocky planets beyond the solar system. Any such planet situated in the right orbit stands a good chance of having liquid water on its surface, and quite possibly life, although a leading scientist involved in the project said it was unlikely to find "any little green men". 4. Developed by the French space agency, CNES, and partnered by the European Space Agency (ESA), Austria, Belgium, Germany, Brazil and Spain, Corot will monitor around 120,000 stars with its 27cm telescope from a polar orbit 514 miles above the Earth. Over two and a half years, it will focus on five to six different areas of the sky, measuring the brightness of about 10,000 stars every 512 seconds. 5. "At the present moment we are hoping to find out more about the nature of planets around stars which are potential habitats. We are looking at habitable planets, not inhabited planets. We are not going to find any little green men," Professor Ian Roxburgh, an ESA scientist who has been involved with Corot since its inception, told the BBC Radio 4 Today programme. 6. Prof Roxburgh said it was hoped Corot would find "rocky planets that could develop an atmosphere and, if they are the right distance from their parent star,they could have water". 7. To search for planets, the telescope will look for the dimming of starlight caused when an object passes in front of a star, known as a "transit". Although it will take more sophisticated space telescopes planned in the next 10 years to confirm the presence of an Earth-like planet with oxygen and liquid water, Corot will let scientists know where to point their lenses.

雅思阅读模拟试题-音乐

雅思阅读模拟试题:音乐 Background music may seem harmless, but it can have a powerful effect on those who hear it. Recorded background music first found its way into factories, shop and restaurants in the US. But it soon spread to other arts of the world. Now it is becoming increasingly difficult to go shopping or eat a meal without listening to music. To begin with, “ muzak ” (音乐广播网) was intended simply to create a soothing (安慰) atmosphere. Recently, however, it’s become big business –thanks in part to recent research. Dr. Ronald Milliman, an American marketing expert, has shown that music can boost sales or increase factory production by as much as a third. But, it has to be light music. A fast one has no effect at all on sales. Slow music can increase receipts by 38%. This is probably because shoppers slow down and have more opportunity to spot items they like to buy. Yet, slow music isn’t always answered. https://www.sodocs.net/doc/987046074.html,liman found, for example, that in restaurants slow music meant customers took longer to eat their meals, which reduced overall sales. So restaurants owners might be well advised to play up-tempo music to keep the customers moving – unless of course, the resulting indigestion leads to complaints! ( )1. The reason why background music is so popular is that ______. A. it can have a powerful effect on those who hear it B. it can help to create a soothing atmosphere C. it can boost sales or increase factory production everywhere D. it can make customers eat their meals quickly ( )2. Background music means ________. A. light music that customers enjoy most B. fast music that makes people move fast C. slow music that can make customers enjoy their meals D. the music you are listening to while you are doing something ( )3. Restaurant owners complain about background music because ______. A. it results in indigestion B. it increases their sales C. it keeps customers moving D. it decreases their sales ( )4. The word “ up-tempo music” probably means_____. A.slow music B.fast music C.light music D.classical music

Since land is generally prepared by hand, one ulupwa cannot take on a very large area; in this sense land has not been a limiting resource over large parts of the province. The situation has already changed near the main townships, and there has long been a scarcity of land for cultivation in the Valley. In these areas registered ownership patterns are becoming prevalent. B Most of the traditional cropping in Luapula, as n the Bemba area to the east, is based on citemene, a system whereby crops are grown on the ashes of tree branches. As a rule, entire trees are not felled, but are pollarded so that they can regenerate. Branches are cut over an area of varying size early in the dry season, and stacked to dry over a rough circle about a fifth to a tenth of the pollarded area. The wood is fired before the rains and in the first year planted with the African cereal finger millet (Eleusinecoracana). C During the second season, and possibly for afew seasons more the area is planted to variously mixed combinations of annuals such as maize,pumpkins (Telfiriaoccidentalis) and other cucurbits, sweet potatoes, groundnuts, Pharsalus beans and various leafy vegetables, grown with a certain amount of rotation. The diverse sequence ends with vegetable cassava, which is often planted into the developinglast-but-one crop as a relay. D Richards (1969) observed that the practice ofcitemene entails a definite division of labour between men and women. A man stakes out a plot in an unobtrusive manner, since it is considered

Next Year Marks the EU's 50th Anniversary of the Treaty A. After a period of introversion and stunned self-disbelief,continental European governments will recover their enthusiasm for pan-European institution-building in . Whether the European public will welcome a return to what voters in two countries had rejected so short a time before is another matter. B. There are several reasons for Europe’s recovering self-confidence. For years European economies had been lagging dismally behind America (to say nothing of Asia), but in the large continental economies had one of their best years for a decade, briefly outstripping America in terms of growth. Since politics often reacts to economic change with a lag,’s improvement in economic growth will have its impact in , though the recovery may be ebbing by then. C. The coming year also marks a particular point in a political cycle so regular that it almost seems to amount to a natural law. Every four or five years, European countries take a large stride towards further integration by signing a new treaty: the Maastricht treaty in 1992, the Treaty of Amsterdam in 1997, the Treaty of Nice in . And in they were supposed to ratify a European constitution, laying the ground for yet more integration—until the calm rhythm was rudely shattered by French and Dutch voters. But the political impetus to sign something every four or five years has only been interrupted,not immobilised, by this setback. D. In the European Union marks the 50th anniversary of another treaty—the Treaty of Rome, its founding charter. Government leaders have already agreed to celebrate it ceremoniously, restating their commitment to “ever closer union” and the basic ideals of European unity. By itself, and in normal circumstances, the EU’s 50th-birthday greeting to itself would be fairly meaningless, a routine expression of European good fellowship. But it does not take a Machiavelli to spot that once governments have signed the declaration (and it seems unlikely anyone would be so uncollegiate as to veto

2019年雅思阅读模拟试题:流程图题(1) BAKELITE The birth of modern plastics In 1907, Leo Hendrick Baekeland, a Belgian scientist working in New York, discovered and patented a revolutionary new synthetic material. His invention, which he named 'Bakelite,’was of enormous technological importance, and effectively launched the modern plastics industry. The term 'plastic' comes from the Greek plassein, meaning 'to mould'. Some plastics are derived from natural sources, some are semi-synthetic (the result of chemical action on a natural substance), and some are entirely synthetic, that is, chemically engineered from the constituents of coal or oil. Some are 'thermoplastic', which means that, like candlewax, they melt when heated and can then be reshaped. Others are 'thermosetting': like eggs, they cannot revert to their original viscous state, and their shape is thus fixed for ever. Bakelite had the distinction of being the first totally synthetic thermosetting plastic. The history of today's plastics begins with the discovery of a series of semi-synthetic thermoplastic materials in the mid-nineteenth century. The impetus behind the development of these early plastics was generated by a number of factors—immense technological progress in the domain of chemistry, coupled with wider cultural changes, and the pragmatic need to find acceptable substitutes for dwindling supplies of 'luxury' materials such as tortoiseshell and ivory.

Climate and Country Wealth Why are some countries stupendously rich and others horrendously poor? Social theorists have been captivated by this question since the late 18th century, when Scottish economist Adam Smith argued in his magisterial work The Wealth of Nations that the best prescription for prosperity is a free-market economy in which the government allows businesses substantial freedom to pursue profits. Smith, however, made a second notable hypothesis: that the physical geography of a region can influence its economic performance. He contended that the economies of coastal regions, with their easy access to sea trade, usually outperform the economies of inland areas. Coastal regions and those near navigable waterways are indeed far richer and more densely settled than interior regions, just as Smith predicted. Moreover, an area's climate can also affect its economic development. Nations in tropical climate zones generally face higher rates of infectious disease and lower agricultural productivity (especially for staple foods) than do nations in temperate zones. Similar burdens apply to the desert zones. The very poorest regions in the world are those saddled with both handicaps: distance from sea trade and a tropical or desert ecology. The basic lessons of geography are worth repeating, because most economists have ignored them. In the past decade the vast majority of papers on economic development have neglected even the most obvious geographical realities. The best single indicator of prosperity is gross national product (GNP) per capita – the total value of a country's economic output, divided by its population. A map showing the world distribution of GNP per capita immediately reveals the vast gap between rich and poor nations. The great majority of the poorest countries lie in the geographical tropics. In contrast, most of the richest countries lie in the temperate zones. Among the 28 economies categorized as high income by the World Bank, only Hong Kong, Singapore and part of T aiwan are in the tropical zone, representing a mere 2 percent of the combined population of the high-income regions. Almost all the temperate-zone countries have either high-income economies (as in the cases of North America, western Europe, Korea and Japan) or middle-income economies (as in the cases of eastern Europe, the former Soviet Union and China). In addition, there is a strong temperate-tropical divide within countries that straddle both types of climates. Most of Brazil, for example, lies within the tropical zone, but the richest part of the nation – the southernmost states –is in the temperate zone. There are two major ways in which a region’s climate affects economic development. First, it affects the prevalence of disease. Many kinds of infectious diseases are endemic to the tropical and subtropical zones. This tends to be true of diseases in which the pathogen spends part of its life cycle outside the human host: for instance, malaria (carried by mosquitoes) and helminthic infections (caused by parasitic worms). Although epidemics of malaria have occurred sporadically as far north as Boston in the past century, the disease has never gained a lasting foothold in the temperate zones, because the cold winters naturally control the mosquito-based

ACADEMIC READING 60 minutes READING PASSAGE 1 You should spend about 20 minutes on Questions 1-13 which are based on Reading Passage 1 below. Striking Back at Lightning With Lasers Seldom is the weather more dramatic than when thunderstorms strike. Their electrical fury inflicts death or serious injury on around 500 people each year in the United States alone. As the clouds roll in, a leisurely round of golf can become a terrifying dice with death - out in the open, a lone golfer may be a lightning bolt's most inviting target. And there is damage to property too. Lightning damage costs American power companies more than $100 million a year. But researchers in the United States and Japan are planning to hit back. Already in laboratory trials they have tested strategies for neutralising the power of thunderstorms, and this winter they will brave real storms, equipped with an armoury of lasers that they will be pointing towards the heavens to discharge thunderclouds before lightning can strike. The idea of forcing storm clouds to discharge their lightning on command is not new. In the early 1960s, researchers tried firing rockets trailing wires into thunderclouds to set up an easy discharge path for the huge electric charges that these clouds generate. The technique survives to this day at a test site in Florida run by the University of Florida, with support from the Electrical Power Research Institute (EPRI), based in California. EPRI, which is funded by power companies, is looking at ways to protect the United States' power grid from lightning strikes. 'We can cause the lightning to strike where we want it to using rockets,' says Ralph Bernstein, manager of lightning projects at EPR!. The rocket site is providing precise measurements of lightning voltages and allowing engineers to check how electrical equipment bears up. Bad behaviour But while rockets are fine for research, they cannot provide the protection from lightning strikes that everyone is looking for. The rockets cost around $1,200 each, can only be fired at a limited frequency and their failure rate is about 40 per cent. And even when they do trigger lightning, things still do not always go according to plan. 'Lightning is not perfectly well behaved,' says Bernstein. 'Occasionally, it will take a branch and go someplace it wasn't supposed to go.' And anyway, who would want to fire streams of rockets in a populated area? 'What goes up must come down,' points out Jean-Claude Diels of the University of New Mexico. Diels is leading a project, which is backed by EPRI, to try to use lasers to discharge lightning safely and safety is a basic requirement since no one wants to put themselves or their expensive equipment at risk. With around $500,000 invested so far, a promising system is just emerging from the laboratory. The idea began some 20 years ago, when high-powered lasers were revealing. their ability to extract electrons out of atoms and create ions. If a laser could generate a line of ionization in the air all the way up to a storm cloud, this conducting path could be used to guide lightning to Earth, before the electric field becomes strong enough to break down the air in an uncontrollable surge. To stop the laser itself being struck, it would not be pointed straight at the clouds. Instead it would be directed at a mirror, and from
