剑桥雅思8-第三套试题-阅读部分-PASSAGE 1-阅读真题原文部分:READING PASSAGE 1You should spend about 20 minutes on Questions 1-13 which are based on Reading Passage 1 below.Striking Back at Lightning With LasersSeldom 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 EPRI. The rocket site is providing precise measurements of lightning voltages and allowing engineers to check how electrical equipment bears up.Bad behaviourBut 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 ionisation 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 there into the sky. The mirror would be protected by placing lightning conductors close by. Ideally, the cloud-zapper (gun)would be cheap enough to be installed around all key power installations, and portable enough to be taken to international sporting events to beam up at brewing storm clouds.A stumbling blockHowever, there is still a big stumbling block. The laser is no nifty portable: it's a monster that takes up a whole room. Diels is trying to cut down the size and says that a laser around the size of a small table is in the offing. He plans to test this more manageable system on live thunderclouds next summer.Bernstein says that Diels's system is attracting lots of interest from the power companies. But they have not yet come up with the $5 million that EPRI says will be needed to develop a commercial system, by making the lasers yet smaller and cheaper. 'I cannot say I have money yet, but I'm working on it, ' says Bernstein. He reckons that the forthcoming field tests will be the turning point - and he's hoping for good news. Bernstein predicts 'an avalanche of interest and support' if all goes well. He expects to see cloud-zappers eventually costing 100, 000 each.Other scientists could also benefit. With a lightning 'switch' at their fingertips, materials scientists could find out what happens when mighty currents meet matter. Diels also hopes to see the birth of 'interactive meteorology' - not just forecasting the weather but controlling it. 'If we could discharge clouds, we might affect the weather, ' he says.And perhaps, says Diels, we'll be able to confront some other meteorological menaces. 'We think we could prevent hail by inducing lightning, ' he says. Thunder, the shock wave that comes from a lightning flash, is thought to be the trigger for the torrential rain that is typical of storms. A laser thunder factory could shake the moisture out of clouds, perhaps preventing the formation of the giant hailstones that threaten crops. With luck, as the storm clouds gather this winter, laser-toting researchers could, for the first time, strike back.Questions 1-3Choose the correct letter, A, B, C or D.Write the correct letter in boxes 1-3 on your answer sheet.1 The main topic discussed in the text isA the damage caused to US golf courses and golf players by lightning strikes.B the effect of lightning on power supplies in the US and in Japan.C a variety of methods used in trying to control lightning strikes.D a laser technique used in trying to control lightning strikes.2 According to the text, every year lightningA does considerable damage to buildings during thunderstorms.B kills or injures mainly golfers in the United States.C kills or injures around 500 people throughout the world.D damages more than 100 American power companies.3 Researchers at the University of Florida and at the University of New MexicoA receive funds from the same source.B are using the same techniques.C are employed by commercial companies.D are in opposition to each other.Questions 4-6Complete the sentences below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Write your answers in boxes 4-6 on your answer sheet.4 EPRI receives financial support from………………………….5 The advantage of the technique being developed by Diels is that it can be used……………….6 The main difficulty associated with using the laser equipment is related to its……………….Questions 7-10Complete the summary using the list of words, A-I, below.Write the correct letter, A-I, in boxes 7-10 on your answer sheet.In this method, a laser is used to create a line of ionisation by removing electrons from 7 ………………………….

These ideas change as local customs and attitudes change, and these changes are reflected in the curriculum, teaching and assessment methods and the expectations of how both students and teachers should behave.词汇讲解：curriculum n. 教学大纲；reflect v. 反映；反射；assessment n. 评价；BTeaching in the late 1800s and early 1900s was very different from today. Rules for teachers at the time in the USA covered both the teacher's duties and their conduct out of class as well. Teachers at that time were expected to set a good example to their pupils and to behave in a very virtuous and proper manner. Women teachers should not marry, nor shou ld they ‘keep company with men.' They had to wear long dresses and no bright colours and they were not permitted to dye their hair. They were not allowed to loiter downtown in an ice cream store, and women were not allowed to go out in the evenings unless to a school function, although men were allowed one evening a week to take their girlfriends out if they went to church regularly. No teachers were allowed to drink alcohol. They were allowed to read only good books such as the Bible, and they were given a pay increase of 25c a week after five years of work for the local school.词汇讲解：manner n. 行为守那么；be expected to：被预期…表示将来时：be expected tobe predicted tobe perspective toCAs well as this long list of ‘dos' and ‘don'ts,' teachers had certain duties to perform each day. In country schools, teachers were required to keep the coal bucket full for the classroom fire, and to bring a bucket of water each day for the children to drink. They had to make the pens for their students to write with and to sweep the floor and keep the classroom tidy. However, despite this list of duties, little was stipulated about the content of the teaching, nor about assessment methods.DTeachers would have been expected to teach the three ‘r’s—reading, writing and arithmetic, and to teach the children about Christianity and read from the Bible every day. Education in those days was much simpler than it is today and covered basic literacy skills and religious education. They would almost certainly have used corporal punishment such as a stick or the strap on naughty or unruly children, and the children would have sat together in pairs in long rows in the classroom. They would have been expected to sit quietly and to do their work, copying long rows of letters or doing basic maths sums. Farming children in country areas would have had only a few years of schooling and would probably have left school at 12 or 14 years of age to join their parents in farm work.词汇讲解：arithmetic：算数；literacy：文学，阅读；religious：的；discrimination：歧视；religious discrimination：歧视。
雅思听力阅读双8分实战经验讲解以下为高分烤鸭在2011年的考试经验，经验写的非常详细，足可以作为考试计划使用了。
先说一下本人的基本情况：本人现在大四，制药工程系，从大三下开始准备留学的一系列工作，由于是理工科，申请的学校要求考GRE，所以先考了GRE，正式准备雅思是在今年1月份开始雅思课之后。
英语基础还行，四六级均在590-600之间，GRE 考了1420+3.5，因为对自己的英语有一定的了解，所以选择考雅思，这次是我第一次考雅思，正好达到了目标的分数，7分。
小分分别是：阅读和听力8，写作和口语6。
我的雅思课从1.20开始，3.19考试。
按老师的建议，两个月差不多每天花6-7小时准备雅思。
一开始的复习就是每次上完课之后完成老师上课布置的作业作为专项训练，课程结束之后就开始各个部分系统的练习。
对于复习，我最深刻的一个体会就是：对于只有1，2个月复习的同学来说充分利用好剑桥系列就足够了！书不在多，用透就行！下面来说说我各个部分的准备情况，希望对大家有一点点帮助。
⑴单词：由于自己本身考过GRE，单词不是问题，又翻了一下剑桥系列发现里面阅读文章的单词基本都认识，所以一开始没打算背单词直接就准备做题了。
后来慢慢发现还是有点差距的，每项考试的侧重点不同，考雅思还是应该背一下雅思词汇，所以就去买了本《剑桥雅思词汇精典》看看，后来又买了《雅思全能牛皮卷》，看了下里面的“雅思核心单词”部分作为单词的复习，感觉还是蛮有用的，里面的单词是按话题分类编排的，对涉及相关话题的写作和口语的训练也有用。
雅思的词汇相对于GRE的单词还是容易的，有了GRE单词的基础这次我没花太多的时间在记忆单词上。
我当时背GRE单词的方法可以让大家作为参考。
我一直觉得单词是靠反复背，反复训练，反复运用才能长久地印在脑海中的。
我把一周的时间分成三个部分，周一周二每天一个list，周三复习周一周二的单词，有时间的话再多背一个list，周四周五周六的安排类似前三天，周日把这一周的单词全部再滚一遍。

雅思精讲阅读班精讲班第8讲讲义Questions 25-28说明：录音开始的2分钟内容已经在上一讲中讲过。
Questions 25-28What is a dinosaur?A. Although the name dinosaur is derived from the Greek for “terrible lizard”, dinosaurs were not, in fact,lizards at all. Like lizards, dinosaurs are included in the class Reptilia, or reptiles, one of the five main classes of Vertebrata, animals with backbones. However, at the next level of classification, within reptiles, significant differences in the skeletal anatomy of lizards and dinosaurs have led scientists to place these groups of animals into two different superorders: Lepidosauria, or lepidosaurs, and Archosauria, or archosaurs.B. Classified as lepidosaurs are lizards and snakes and their prehistoric ancestors. Included among the archosaurs, or “ruling reptiles”, are prehistoric and modern crocodiles, and the now extinct thecondonts, pterosaurs and dinosaurs. Paleontologists believe that both dinosaurs and crocodiles evolved, in the later years of the Triassic Period (c. 248-208 million years ago), from creatures called pseudosuchian thecodonts. Lizards, snakes and different types of thecondont are believed to have evolved earlier in the Triassic Period from reptiles known as eosuchians.C. The most important skeletal differences between dinosaurs and other archosaurs are in the bones of the skull, pelvis and limbs. Dinosaur skulls are found in a great range of shapes and sizes, reflecting the different eating habits and lifestyles of a large and varied group of animals that dominated life on Earth for an extraordinary 165 million years. However, unlike the skulls of any other known animals, the skulls of dinosaurs had two long bones known as vomers. These bones extended on either side of the head, from the front of the snout to the level of the holes in the skull known as the antorbital fenestra, situated in front of the dinosaur’s orbits or eyesockets.D. All dinosaurs, whether large or small, quadrupedal or bipedal, fleet-footed orslow-moving, shared a common body plan. Identification of this plan makes it possible to differentiate dinosaurs from any other types of animal, even other archosaurs. Most significantly, in dinosaurs, the pelvis and femur had evolved so that the hind limbs were held vertically beneath the body, rather than sprawling out to the sides like the limbs of a lizard. The femur of a dinosaur had a sharply in-turned neck and a ball-shaped head, which slotted into a fully open acetabulum or hip socket. A supra-acetabular crest helped prevent dislocation of the femur. The position of the knee joint, aligned below the acetabulum, made it possible for the whole hind limb to swing backwards and forwards. This unique combination of features gave dinosaurs what is know as a “fully improved gait”. Evolution of this highly efficient method of walking also developed in mammals, but among reptiles it occurred only in dinosaurs.E. For the purpose of further classification, dinosaurs are divided into two orders: Saurischia, or saurischian dinosaurs, and Ornithischia, or ornithischian dinosaurs. This division is made on the basis of their pelvic anatomy. All dinosaurs had a pelvic girdle with each side comprised of three bones: the pubis, llium and ischium. However, the orientation of these bones follows one of two patterns. In saurischian dinosaurs, also known as lizard-hipped dinosaurs, the pubis points forwards, as is usual in most types of reptile. By contrast, in ornithischian, or bird-hipped, dinosaurs, the pubis points backwards towards the rear of the animal, which is also true of birds.（26F. Of the two orders of dinosaurs, the Saurischia was the larger and the first to evolve. It is divided into two suborders: Therapoda, or therapods, and Sauropodomorpha, or sauropodomorphs. The therapods, or “beast feet”, were bipedal, predatory carnivores. They ranged in size from the mighty Tyrannosaurus rex, 12m long, 5.6m tall and weighing as estimated 6.4 tonnes, to the smallest known dinosaur, Compsognathus, a mere 1.4m long and estimated 3kg in weight when fully grown. The sauropodomorphs, or “lizard feet forms”, included both bipedal and quandrupedal dinosaurs. Some sauropodomorphs were carnivorous or omnivorous but later species were typically herbivorous. They included some of the largest and best-known of all dinosaurs, such as Diplodocus, a huge quadruped with an elephant-like body, a long, thin tail and neck that gave it a total length of 27m, and a tiny head.G. Ornithischia dinosaurs were bipedal or quadrupedal herbivores. They are now usually divided into three suborders: Ornithipoda, Thyreophora and Marginocephalia. The ornithopods, or “bird feet”, both large and small, could walk or run on their long hind legs, balancing their body by holding their tails stiffly off the ground behind them. An example is lguanodon, up to 9m long, 5m tall and weighing 4.5 tonnes. The thyreophorans, or “shield bearers”, also known as armoured dinosaurs, were quadrupedswith rows of protective bony spikes, studs, or plates along their backs and tails. They included Stegosaurus, 9m long and weighing 2 tonnes.H. The marginocephalians, or “margined heads”, were bipedal or quadrupedal ornithischians with a deep bony frill or narrow shelf at the back of the skull. An example is Triceratops a rhinoceros-like dinosaur, 9m long, weighing 5.4 tonnes and bearing a prominent neck frill and three large horns.Questions 25-28hoose one phrase (A-H) from the List of features to match with the Dinosaurs listed below. Write the appropriate letters (A-H) in Boxes 25-28 on your answer sheet.The information in the completed sentences should be an accurate summary of the points made by the writer.NB.
