英猪四怨快速闻筱专顼体习（金备案解斩丿（一）Skimming and ScanningDirections: In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1. For questions 1-7, choose the best answer from the four choices marked [A], [B], [C] and [D]. For question 8-10, complete the sentences with the in formation give n in the passage ・Animals on the MoveIt looked like a seene from “Jaws” but without the dramatic music. A huge shark was slowly swimming through the water, its tail swinging back and forth like the pendulum of a clock・Suddenly sensitive nerve ending in the shark， s skin picked up vibrations of a struggling fish. The shark was immediately transformed into a deadly, efficient machine of death・ With muscles taut, the shark knifed through the water at a rapid speed・ In a flash the shark caught its victim, a large fish, in its powerful jaws・ Then, jerking its head back and forth, the shark tore huge chunks of flesh from its victim and swallowed them・ Soon the action was over.Moving to SurviveIn pursui ng its prey, the shark dem on strated in a dramatic way the imports nt role of movement, or locomotion, in animals・Like the shark, most animals use movement to find food. They also use locomotion to escape en emies, find a mate, and explore new territories. The methods of locomoti on in elude crawling, hopping, slithering, flying, swimming, or walking・Humans have the added advantage of using their various inventions to move about in just about any kind of environ me nt. Automobiles, rockets, and submari nes tra nsport huma ns from deep oceans to as far away as the moon. However; for other animals movement came about naturally through millions of years of evolution. One of the most successful examples of animal locomotion is that of the shark. Its ability to quickly zero in on its prey has always impressed scientists. But it took a detailed study by Duke University marine biologists S. A・ Wainwright, F. Vosburgh, and J. H. Hebrank to find out how the sharks did it. In their study the scientists observed sharks swimming in a tank at Marine land in Saint Augustine, Fla. Movies were taken of the sharks' movements and analyzed. Studies were also made of shark skin and muscle.Skin Is the KeyThe biologists discovered that the skin of the shark is the key to the animaT s high efficiency in swimming through the water. The skin contains many fibers that crisscross like the in side of a belted radial tire・ The fibers are called collagen fibers・ These fibers can either store or release large amounts of energy depending on whether the fibers are relaxed or taut. When the fibers are stretched, energy is stored in them the way energy is stored in the string of a bow when pulled tight. When the energy is released, the fibers become relaxed.The Duke University biologists have found that the greatest stretching occurs where the shark bends its body while swimming. During the body' s back and forth motion, fibers along the outside part of the bending body stretch greatly・Much potential energy is stored in the fibers. This energy is released when the shark，s body snaps back the other way.As energy is alternately stored and released on both sides of the animaT s body, the tail whips strongly back and forth・ This whip-like action propels the animal through the water like a living bullet.Source of EnergyWhat causes the fibers to store so much energy? In finding the answer the Duke University scie ntists I ear ned that the shark，s similarity to a belted radial tire does n' t stop with the skin. Just as a radial tire is inflated by pressure, so, too, is the area just under the shark' s collagen u radials ” ・ In stead of air pressure, however, the pressure in the shark may be due to the force of the blood pressing on the collagen fibers・When the shark swims slowly, the pressure on the fibers is relatively low. The fibers are more relaxed, and the shark is able to bend its body at sharp angles. The animal swims this way when looking around for food or just swimming・ However; when the shark detects an important food source, some fantastic involuntary changes take place・The pressure inside the animal may in crease by 10 times ・ This pressure cha nge greatly stretches the fibers, enabling much energy to be stored・This energy is then transferred to the tail, and the shark is off. The rest of the story is predictable.Dolphin Has Speed RecordAnother fast marine animal is the dolphin. This seagoing mammal has been clocked at speeds of 32 kilometers (20 miles) an hour. Biologists studying the dolphin have discovered that, like the shark, the animal s efficient locomotion can be traced to its skin. A dolphin‘ s skin i s made up in such a way that it offers very little resista nee to the water flowing over it. Normally when a fish or other object moves slowly through the water, the water flows smoothly past the body. This smooth flow is known as laminar flow. However, at faster speeds the water becomes more turbulent along the moving fish・This turbulenee muses friction and slows the fish down.In a dolphin the skin is so flexible that it bends and yields to the waviness of the water. The waves, in effect, become tucked into the skin' s folds. This allows the rest of the water to move smoothly by in a laminar flow. Where other animals would be slowed by turbulent water at rapid speeds, the dolphin can race through the water at record breaking speeds・Other Animals Less EfficientNot all animals move as efficiently as sharks and dolphins. Perhaps the greatest loser in locomotion efficiency is the slug・ The slug, which looks like a snail without a shell, lays down a slimy trail over which it crawls・ It uses so much energy producing the slimy mucus and crawling over it that a mouse traveling the same distanee uses only one twelfth as much energy.Scientists say that because of the slug' s inefficient use of energy, its lifestyle must be restricted. That is, the animals are forced to confine themselves to small areas for obtaining food and finding proper living conditions. Have humans ever been faced with this kind of problem?1.According to the passage, a shark can use movement to do somethingexce pt ___________ ■[A]to find food[B]to avoid being chased by its enemies[C]to find a new place to live[D]to show its braveness2.Examples of automobiles, rockets and submarines are used to show that[AJhumans are the most clever living creatures in the world[B]human inventions enable us to travel in almost any kind of environment[CJhumans are very successful in inventing transportation tools[D]humans can，t move like other animals in any circumstances3.What is the key to the shark" s swift locomotion in water?[A]The skin.

For questions 8-10, complete the sentences with the information given in the passage.About Story ReaderParents dearly hope their children learn to read well. They also hope their children learn to read quickly and easily, so that they，re ready for the dema nds put on them by school and the world.Kids want to learn how to read, but they also crave entertainment, whether it' s quiet and passive or dynamic and interactive. The aims of the Story Reader line of electronic books are to entertain children and to introduce them to the processof learning how to read in a gentle and enjoyable way・ In this article, we? II show you how Story Reader works and if it accomplishes that goal.Story Reader is a compact, roughly 12-inch-by-12-inch plastic case (with a carrying handle ) that ope ns to reveal an actual book that fits sn ugly into the Reader itself. Story Reader" s core feature is that it ''reads11 the book aloud to a child as he follows along. The child turns the pages when prompted by the Story Reader or at his own pace.Books have both text and illustrations. The electronic book responds to the child' s wishes. The Story Reader speaks the text for the curre nt page .If the child tur ns back a few pages, the Reader recog nizes that page and reads it agai n. Kids react well to this in teractivity because it in stills a sense of cun trol over the story ・There are Three Story Reader ProductsThe basic Story Reader, introduced in 2003, is as described above and is in tended for kids three years of age and older.Each book has a small companion cartridge that slides into a port on the case and contains the audio encoded into its memory for the story.The device has a volume control but no on/off switch-a deliberate choice so kids can simply open it up and begin reading. It takes four AAA batteries (or operates on household current with an optional adaptor) and retails for around $20.Find out more information about the more than 60 titles at the Story Reader website・Early in 2006, Publications In ter national, Ltd.-Story Reader s publisher-i ntroduced My First Story Reader, designed for newborns to kids up to age three. As with the original, a narrator reads the story aloud, this time from a 12-page book made from a heavier paperstock that in eludes sound effects and music to en live n the experie nee.My First Story Reader features two play modes, one with narration, the other that asks questions about the images on each page・ The child can press any of three buttons to answer basic questions about shapes and colors. The last two pages ofeach My First Story Reader book features a sing-along rhyming melody. My First Story Reader retails for about $20.Late in 2006, Publications In ter natio nal in troduced a video versio n of Story Reader called Story Reader Video Plus for kids up to the age of seven. Retailing for about $35, it combines a stand・alone Story Reader with an "Animated Story Mode11that plays through your televisi on and in eludes a H Lear ning Game Mode11.The Animated Story Mode works just as it sounds-when you connect it to your television throughcolor-coded cables, the story appears on screen and changes as your child turns the pages. Kids get to the Learning Game Mode by turning to thelast page of the book・ There, they can choose from five educational games・ While it depends on the story, gen erally there are patter n games, memory games, and platform games ・ Similar to Ninte ndo games like Super Mario Brothers, in a platform game the child uses the in eluded controller to guide him through the environment and conquer obstacles・Story Reader Video Plus isn' t a video game, tech nically, and Publications In ter national bills the Story Reader line more as electronic books than toys. This reassures many parents, and it' s why Story Reader is sold in bookstores and in the book section of major retailers・What about the Educational Underpinnings of Story Reader?Studies show an alarming decline in reading rates among all age groups in America, especially among the young.Children are bombarded on a daily basis with multiple forms of entertainment that compete with traditional learning.Kids naturally emulate the adults in their lives, and seeing their parents and other family members enjoy reading is a powerful motivator. Establishing and keeping a Read-At-Home Night helps families spend time together and helps form lifelong reading habits in children.Here' s how you do it:•Set aside one night a week in your household and call it M Read-At-Home Hour H-or anything you prefer. Establish a time allotment that works for your family, for example, 30 minutes or an hour.•Minimize interruptions from the TV, computer, and video games-and turn on the telephone answering machine・•Choose one book for the en tire family to read aloud together, or en courage in dividual family members to choose their own books to read quietly・ Electronic books can work in this con text, as well.•Fin ally, sit down, relax, and read ・1.The aims of the Story Reader line of electronic books are _[A]to entertain and teach children[B]to play with the child[C]to ease the parents' burden[D]to ease the teachers， burden2.Story Reader" s key characteristic is that _[A]it "reads" the book which the child likes[B]it "reads" the book while the child plays[C]it "reads" the book while the child follows along[D]it "reads" the book while the parent works3.Children _ are suitable users of the basic Story Reader.[A]up to six mon ths old[B]up to age one[C]up to age two[D]up to age three4.The basic Story Reader for sale is about _[A]12 dollars[B]20 dollars[C]35 dollars[D]60 dollars5・ My First Story Reader is characteristic with[A]two play modes[B]three play modes[C]four play modes[D]five play modes6.Story Reader Video Plus is a video version of Story Reader designed for _[A]newborns to kids up to age three[B]newborns to kids up to age seven[C]children up to the age of five[D]children up to the age of seven7.How many games can children choose from the Animated Story Mode?[A]four[B]five[C]six[D]seven8.If the Story Reader speaks the text for the current page, but the child turns back a few pages, it will ___________te in 2006, we can infer that there were Story Reader products ____________ .10.Like Super Mario Brothers, children in a platform game use the included controllers(三)Reading Comprehension (Skimming and Scanning) (15 minutes)Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1. For questions 1-7, choose the best answer from the four choices marked [A], [B], [ C ]and [D]> For questions 8-10, complete the sentences with the information given in the passage.The Right Amount of EnergyWe all enjoy being aro und people with en ergy ・ They in spire us. They are stimulati ng, fun, and uplifting. An energetic person has passion in his voice, a bounce in his step, and a smile on his face・Energy makes a person likable, and likability is akey ingredient in persuasive communications. Many business professionals underestimate the energy level required to gen erate enthusiasm among their liste ners ・ But electrifyi ng speakers bring it. They have an energy that is several levels higher than the people they are attempt!ng to in fluence.Most business professionals could use an energy boost for public speaking situations such as Webi nars, podcasts, staff meeti ngs, con fere nee calls, and televisi on and radio interviews. Each of these opportunities requires a higher level of energythan would n ormally be appropriate if you were just chatti ng to some one in the hallway. But how do you project the right level of vigor without seeming over the top? By weighing yourself on an energy scale. And on this scale, more is better.The Energy ScaleRecently I helped an executive prepare for his first major presentation in his new role・"Tell me where your energy is right now on a scale of one to ten/ I asked・"One being fast asleep and ten being Jim Cramer on Mad Money. You know, the guy who' s yelling and gesturing wildly on his CNBC show. Where are you now?HH A three/* the speaker replied.H OK, what would it feel like to be a seven, eight or nine? Give it a try,111 suggested.If they5 re being honest, most presenters place themselves at a three to six on the energy scale・That means there is plenty of room to boost your energy while not appearing too zany・ But keep in mind, once you hit a ten or higher, you could be the next YouTube (GOOG) hit-which is not necessarily your top objective! Here are several surefire strategies to boost your energy presence.1.Practice leaving your comfort zone.Record several minutes of your presentation as you would normally deliver it: Play it back, preferably with some one else watching and liste ning as well- Ask yourself and the observer, where am I on the energy scale? Now try it again. This time,break out of your comfort zone. Ham it up. Raise your voice・ Use big gestures. Put a big smile on your face・ Get to a point where you would feel slightly awkward and uncomfortable. Now watch it. Most likely your energy level will be far more engaging and still remain appropriate fur the situation.2.Smile and have fun.Why do most people seem to enjoy Virgin entrepreneur Richard Branson? Because the guy has fun and it shows・ He always has a warm, engaging smile on his face. Of course, you can argue that it" s easy to walk aro und with a smile when you' re worth $4 billi on! But seriously, smile .It won，t hurt and it will make you more likable. Most business professionals don' t smile as much as they should during presentations. r m helping some executives prepare for CES, the big Consumer Electronics Show inJanuary where they will announce new products・ They get so caught up in the slides and what they' re going to say ( as they should during preparation ), they forget that new products bring joy to their consumers・ In most cases-with the exception of bad news, of course-the first and last thing you say to yourself before launching into your presentation should be, “Have3・ Get your body moving.Many people are uncomfortable using expansive hand gestures. Don? t be. I spoke to David McNeill at the University of Chicago, who is known for his research into gesture and speech・ He says that clear, con fide nt speakers use hand gestures and that the gestures leave a positive impression on listeners・He went on to say that using gestures will help you speak better because for most of us it takes effort not to use gestures・Don，t be afraid of using your hands.AOL' s (TWX) is one of my favorite video search engines・ I use it to retrieve clips of business speakers to study their body Ianguage. Symantec' s (SYMC) John Thompson, Oracle' s (ORCL) Larry Ellison, Cisco' s (CSCO) John Chambers, and eBay' s (EBAY) Meg Whitman are excellent examples of people with con fident, en ergetic body Ian guage.4.Study TV and radio personalities.Stars of television and radio who score high on the likability scale have high-energy personalities ・ I had a conversation with Suze Orman over the phone a couple of years ago and remember it to this day. Her energy comes right through the speaker. What you see on her CNBC show is what you get behind the seenes. High energy・ The other day I watched Food Network (SSP) star Rachael Ray sign books at a mall where I happened to be shopping・Sometimes critics poke fun at her M perky M personality and phrases like "yum-o/ but the fact is she has energy and millions of viewers enjoy it. The networkmorning-show hosts are typically chosen for their energetic personalities・ Today s Matt Lauer on NBC (GE) and The EarlyShow, s Julie Chen on CBS (CBS) are excellent examples, but there are many others on morning television.Remember, maintaining an energetic presenee is very difficult to do unless you' re involved with somethi ng you enjoy. If you are truly passi on ate about your compa ny, product, or service, then show it. Speak with energy and vitality. Your listenerswill love you for it.1.From the first paragraph, what is a key point in persuasive communication?[A]Stimulation.[B]Uplitting.[C]Fun.[D]Likability.2.Have an en ergy several levels higher tha n the people they are attempt! ng to in fluence ・[A]Electrifying speakers[B]Business professionals[C]Und.vnamic persons[D]Listeners3.How do people show the right level of energy without seeming over the top' ?[A]By underestimating the energy level.[B]By undervaluing the energy level.[C]By estimating an energy scale・[D]By using a lower level of energy・4.The scale of the energy is[A]seven, eight or nine[B]ten or higher[C]three to six[D]one to ten5.What does the example mean in the third paragraph?[A]There is little room to boost your energy while not appeanng too zany.[B]There is a little room to boost your energy while not appearing too zany.[C]There is much room to boost your energy while not appearing too zany.[D]There is no room to boost your energy while not appearing too zany.6.Why is Virgi n en trepre neur Richard Brans on popular?[A]Because he has fun and it shows・[B]Because he doesn' t smile as much as he should during presentations・[C]Because he is very humorous・[D]Because he is famous.7.David McNeill says that con fide nt speakers use _[A]hand gestures[B]speech[C]smile[D]expression8.1 use AOL' s (TWX) to retrieve clips of business speakers to _____________9.Stars of television and radio who score high on the lik ability scale have ____________10.Maintaining an energetic presenee is very difficult to do unless ___________（四）The EarthPower and LightCompared to the rest of the universe, the Earth is very small. Our planet and seven others orbit the Sun, which is only one of about 200 billion stars in our galaxy. Our galaxy, the Milky Way, is part of the un iverse, which in eludes millions of othergalaxies and their stars and planets・ By comparison, the Earth is microscopic・Compared to a pers on, on the other hand, the Earth is en ormous .It has a diameter of 7,926 miles ( 12,756 kilometers) at the equator; and it has a mass of about 6 x 1024 kilograms・ The Earth orbits the Sun at a speed of about 66,638 miles per hour (29.79 kilometers per second)・ Don' t dwell on those nu mbers too long, though; to a lot of people, the Earth is in conceivably, mind-bogglingly big. And it? s just a fraction of the size of the Sun.From our perspective on Earth, the Sun looks very small・ This is because it' s about 93 million miles away from us. The Sun， s diameter at its equator is about 100 times bigger than Earth' s, and about a milli on Earths could fit in side the Sun. TheSun is inconceivably, mind-bogglingly bigger.But without the Sun, the Earth could not exist .In a sen se, the Earth is a giant machi n 巳full of moving parts and complex systems. All those systems need power, and that power comes from the Sun.The Sun is an enormous nuclear power source-through complex reactions, it transforms hydrogen into helium, releasing light and heat・ Because of these reactions, every square meter of our planet s surface gets about 342 Watts of energy from the Sun every year. This is about 1.7 ~ 1017 Watts total, or as much as 1.7 billion large power plants could generate・ You can learn about how the Sun creates energy in How the Sun Works.When this energy reaches the Earth, it provides power for a variety of reactions, cycles and systems .It drives the circulati on of the atmosphere and the ocea ns. It makes food for plants, which many people and animals eat・ Life on Earth could not exist without the Sun, and the planet itself would not have developed without it.To a casual observer; the Sun' s most visible contributions to life are light, heat and weather.Night and DaySome of the Sun' s biggest impacts on our planet are also its most obvious. As the Earth spins on its axis, parts of the planet are in the Sun while others are in the shade .In other words, the Sun appears to rise and set・The parts of the world that are in daylight get warmer while the parts that are dark gradually lose the heat they absorbed during the day・You can get a sense of how much the Sun affects the Earth' s temperature by standing outside on a partly cloudy day.When the Sun is behind a cloud, you feel noticeably cooler than when it isn' t・ The surface of our planet absorbs this heat from the Sun and emits it the same way that pavement continues to give off heat in the summer after the Sun goes down. Ouratmosphere does the same thing-it absorbs the heat that the ground emits and sends some of it back to the Earth.The Earth9 s relationship with the Sun also creates seasons・ The Earth? s axis tips a little-about 23.5 degrees. One hemisphere points toward the Sun as the other points away・ The hemisphere thatpoints toward the Sun is warmer and gets more light-it，s summer there, and in the other hemisphere it/ s win ter. This effect is less dramatic n ear the equator tha n at the poles, since the equator receives about the same amount of sun light all year. The poles, on the other hand, receive no sun light at all duri ng their win ter mon ths z which is part of the reason why they' re froze n.Most people are so used to the differences between night and day (or summer and winter) that they take them for granted・But these changes in light and temperature have an enormous impact on other systems on our planet. One is the circulation of air through our atmosphere. For example:The Sun shines brightly over the equator. The air gets very warm because the equator faces the Sun directly and because the ozone layer is thinner there.As the air warms, it begins to rise, creating a low pressure system. The higher it rises, the more the air cools・ Water condenses as the air cools, creating clouds and rainfall. The air dries out as the rain falls・ The result is warm, dry air, relatively high in our atmosphere・Because of the lower air pressure, air rushes toward the equator from the north and south・ As it warms, it rises, pushing the dry air away to the north and the south.The dry air sinks as it cools, creating high-pressure areas and deserts to the north and south of the equator.This is just one piece of how the Sun circulates air around the world-ocean currents, weather patter ns and other factors also play a part. But in gen eral, air moves from high-pressure to low-pressure areas, much the way that high-pressure air rushes from the mouth of an inflated ballo on whe n you let go. Heat also gen erally moves from the warmer equator to the cooler poles ・Imagine a warm drink sitting on your desk-the air around the drink gets warmer as the drink gets colder. This happens on Earth on an enormous scale・The Coriolis Effect, a product of the Earth' s rotation, affects this system as well. It causes large weather systems, like hurricanes z to rotate. It helps create westward-running trade winds near the equator and eastward-running jet streams in the northem and southern hemispheres・These wind patter ns move moisture and air from one place to ano ther, creating weather patterns. (The Coriolis Effect works on a large scale-it doesn' t really affect the water draining from the sink like some people suppose・)The Sun gets much of the credit for creating both wind and rain. When the Sun warms air in a specific location, that air rises, creating an area of low pressure. More air rushes in from surrounding areas to fill the void, creating wind. Without the Sun, there wouldn' t be wind. There also might not be breathable air at all.Water and FireThe Sun has a huge effecton our water. It warms the oceans around the tropics, and its absence cools the water around the poles・ Because of this, ocean currents move large amounts of warm and cold water, drastically affecting the weather andclimate around the world. The Sun also drives the water cycle, which moves about 18,757 cubic miles (495,000 cubic kilometers) of water vapor through the atmosphere every year.If you' ve ever gotten out of a swimming pool on a hot day and realized a few minutes later that you were dry again, you have firsthand experienee with evaporation. If you， ve seen water form on the side of a cold drink, you' ve seen condensation inaction. These are primary components of the water cycle, also called the hydrologic cycle, which。

也是一种快读。
但不同于略读。
目的：为寻找文章中某些特定的信息带着问题去寻找答案，如数字、人名、地名、某一细节等。
方法：读者首先确定所要搜寻的信息的关键词进行快速寻读，忽略无关部分。
1、快速阅读的应试策略1.1 文章分类1) 带小标题的文章: 文章每一部分,都有一个总括性的小标题,小标题一般概括这一部分的主题;2) 不带小标题的文章: 没有明显的每一部分的分隔,需通过略读找出主题句或主题词(特别关注首段或段尾).2. 命题规律规律一: 问题设置顺序与行文顺序基本一致;规律二: 问题通常为文章的主要内容及与主要内容紧密联系的细节;规律三: 包含数字,年代,人名,地名,机构名称等显著信息及用于描述或修饰主要内容的从句,短语等往往是命题的重点.3、快速阅读选择题的做法做法与深度阅读题型相似，但是难度相对较低，正确的选项往往是原文内容的直接重现，或者是简单的同义替换。
大学英语四级考试快速阅读理解技巧新
大学英语四级考试快速阅读技巧一.测试目的快速阅读，顾名思义，它的目的在于测试考生单位时间当中的阅读量，其实四级对速度的考查是近几年一直延续的一种结果。
同时，在解答题目方面，快速阅读并不强调一定要像精读文章那样通篇认真研究，相反，快速阅读题目更强调测试考生在实践语言环境中查询有效信息的能力，这也反映出四六级考试试图提升考生实际应用能力的改革方向。
二.测试形式快速阅读要求考生在15 分钟内完成一篇1100字左右的文章和后面的 10 道题。
前面 7 个题是判断正误（包括NG），后 3 个是填空题填根据阅读的理解，填三到四个单词( 答案基本都是原文中出现的原词)。
快速阅读的文章一般分为小标题+题目和无小标题+题目两种类型。
该题型需要通过略读和寻读法，乃至文章逻辑关系、标点符号等方面的综合运用，实现对随后的题目有效的判断和填写。
三.基本要求1. 快速阅读的文章基本都是专业题材的文章，很多考生可能会觉得很陌生，但是对于 CET-4 的快速阅读开始来说，只要求考生对题目所提到的信息在原文中能够找到即可，只是有时需要简单的同义词替换。
2. 略读（ Skimming）和寻读（ Scanning）的能力在大学英语四级考试中显得尤为重要。
3. 快速阅读要求考生的阅读速度是每分钟 110-140 词。
四.快速阅读方法1.推测（prediction）阅读正文前，就标题（如果有标题的话）来合理推测资料的大概内容，也可在读了一段之后预测下段内容。
这对快速理解和整体把握文章内容以及推测出生词的词义范围有积极的意义。
2.读关键词句（key words and topic sentences）在对文章的整体内容有了基本认识的基础上，我们学会抓主要的词句，找出段落中的主题句，从而正确领会文章的主要内容。

大学英语四级考试中快速阅读的答题技巧一、了解考试规则合理安排考试时间在大学英语四级考试中，快速阅读位于作文之后，作文的时间是前三十分钟，之后的十五分种，是快速阅读答题时间，这两部分都要求在答题卡I上面做答。
在实际考试中，为了控制快速阅读的答题时间，在考试进行到四十五分钟时，监考教师会将答题卡I收回。
这就要求考生不仅要在有限的时间内完成阅读，还要将答案正确地填涂在答题卡上。
当作文时间结束，快速阅读开始时，很多监考教师都会发现，有的考生还在写作文，不是抓紧时间进行快速阅读，这样做的结果是占用了快速阅读的时间，势必影响考生心理，影响考试成绩。
而另外有些考生，不了解考试规则，错误地以为早完成作文，就可以提前做快速阅读。
其实不然，在四级考试中，监考教师会在考试进行到第二十五分钟时，才会将试题册发下去，此时的考生并不能翻看试题册，当考试进行到第三十分钟，写作时间结束时，监考教师发出指令，考生才可以打开试题册，进行快速阅读。
这就意味着，考生最多只有十五分钟的时间做快速阅读。
因此，考生一定要合理安排写作和快速阅读的答题时间，只有时间充足了，才能保证整个考试的答题质量。
二、有效的答题技巧是得分的关键快速阅读是考生在四级考试中遇到的第一道主观题，因此，它的答题情况会影响到考生整场考试的心态。
快速阅读看起来文章长，时间短，难度大，但实际上，只要考生了解了快速阅读的命题规律并掌握答题技巧，就会觉得它是所有题型中最容易的。
考生在做快速阅读时，首先应该明确一个问题，那就是快速阅读与其它胚型的要求大不相同。
其它题型(如仔细阅读、完型填空、翻译等)对文章中几乎每句话、每个词的要求都很高，考生必须全部读懂才能做题，而快速阅读的文章不要求完全理解，只要求能通过略读(skimming)或查读(scanning)的方法找到题干的信息，根据原文内容加以筛查，就能够作出正确的选择。
因此，有效的答题技巧是快速阅读这部分的得分关键。
技巧一：略读(skimming)原文，了解文章大意。

Despit occasional alarms, the country escaped any postw ar depression and lived in a state of boom. An economic survey of the year 1955, a typical year of the 1950’s, may be typical as illustrating the rapid economic growth of the decade. The national output was value at 10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The production of manu facturers was about 40 percent more than it had averaged in the years immediatel y following World War 2. The country’s business spent about 30billion dollars fo r new factories and machinery. National income available for spending was almost a third greater than it had been it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find the m . Only agriculture complained that it was not sharing in the room. To some obs ervers this was an ominous echo of the mid-1920’s . As farmer’s shre of their p roducts declined , marketing costs rose. But there were , among the observers of the national economy, a few who were not as confident as the majority . Those f ew seemed to fear that the boom could not last and would eventually lead to the opposite-depression.1. What is the best title of the passage?a. The Agriculatural Trends of 1950’sb. The Unemployment Rate of 1950’sc. U.S. Economy in the 50’sd. The Federal Budget of 19522. In Line 4 , the word “boom” could best be replaced by______.a. nearby explosionb. thunderous noisec. general public supportd. rapid economic growth3. It can be inferred the national from the passage that most people in the Unit ed States in 1955 viewed the national economy with an air of _________.a. confidenceb. confusionc. disappointmentd. suspicion4. Which of the following were LEAST satisfied with the national economy in the 1950’s?a. Economistsb. Farmersc. Politiciansd. Steelworkers5. The passage states that incom available for spending in the U.S. was greater in 1955 than in 1950 . How much was it ?b. 50％c. 33％d. 90％2/200答案：cdabc3/200Women are also underrepresented in the administration and this is because there are so few women full professors. In 1985,Regent Beryl Milburn produced a report blasting the University of Texas System adminitration for not encouraging women. The University was rated among the lowest for the system.In a 1987 update ,Milbu rn commended the progress that was made and called for even more improvement. One of the positive results from her study was a System-wide program to inform w omen of available administrative jobs.College of Communication Associate Dean Patrica Witherspoon,said it is important that woman be flexible when it comesto relocating if they want to rise in the r anks.Although a woman may face a chilly climate on campus , many times in order for h er to succeed , she must rise above the problems around her and concentrate on h er work.Until women make up a greater percentage of the senior positions in the Universi ty and all academia,inequities will exist."Women need to spend their energies and time doing scholarly activities that are important here at the University." Spirduso said. "If they do that will be succ essful in this system.If they spend their time in little groups mourning the sex ual discrimination that they think exists here, they are wasting valuable study time."1.According to Spirduso,women need to ____.a.produce a report on sexual discriminationb.call for further improvement in their working conditionsc.spend their energies and time fighting against sexual discriminationd.spend more time and energy doing scholarly activities2.From this passage ,we know that _____.a.there are many women full professors in the University of Texasb.women play an important part in adminitrating the Universityc.the weather on the campus is chillyd.women make up a small percentage of the senior positions in the University3.Which of the following statements is true?a.the number of women professors in the University in 1987 was greater than that of 1985b.the number of women professors in the University in 1987 was smaller than that of 1985c.the number of women professors was the same as that of 1985d.more and more women professors thought that sexual discrimination did exit in the University4.One of the positive results from Milburn's study was that _____.a.women were told to con centrate on teir workb.women were given information about available administrative jobsc.women were encouraged to take on all the administrative jobs in the Unversityd.women were encouraged to do more scholarly activities5. The title for this passage should be _______.a.The University of Texasburn's Reportc.Women Professorsd.Sexual Discrimination in Academia3/200答案：ddabd4/200Today ,as in every other day of the year ,more than 3000 U.S. adlescents will sm oke their first cigarette on their way to becoming regular smokers as adults. Du ring their lifetime,it can be expected that of these 3000 about 23 will be murde red,30 will die in traffic accidents, and nearly 750 will be killed by a smoking -related disease. The number of deaths attributed to cigarette smoking outweitht s all other factors, whether voluntary or involuntary, as a cause of death. Since the late 1970s, when daily smoking among high school seniors reached 30 pr ecent , smoking rates among youth have declined . While the decline is impressiv e ,several important issues must be raised.First, in the past several years,smoking rates among youth have declined very li ttle. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,sever al recent studies have indicate high school dropouts have excessively high smoki ng rates, as much as 75 percent .Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the N aional Cancer Instiute (NCI) began its current effort to determine the most effe cive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by ____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smok er.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very littleb.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds4/200答案：bdbdb5/200The food we eat seems to have profound effects on our health.Although science ha s made enormous steps in making food more fit to eat ,it has, at the same time,m ade many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is relat ed to the diet as well,especially cancer of the colon. Different cultures are mo re likely to cause certain different illnesses because of the food that is chara cteristic in these cultures. That food is related to illness is nto a new discov ery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additivies,caused cance r. Yet, these carcinogenic additives remain in our food, and it becomes more dif ficult all the time to know which things on the packaging labels of processed fo od are helpful or harmful. The additives which we eat are not all so direct. Far mers often give penicillin to beef and living animals, and because of this ,peni cillin has been found in the milk of treated cow. Sometimes similar drugs are gi ven to animals not for medical purposes,but for financial reasons. The farmers a re simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to c ontrol these procedures, the practices continue.1.What is the best possible title of the passage?a.Drug and Foodb.Cancer and Healthc.Food and Healthd.Health and Drug2.Which of the following statements is NOT ture?a.Drugs are always given to animals for medical reasonsb.Some of the additives in our food are added to the food itself and some are gi ven to the living animalsc.Researchers have known about the potential dangers of food additives for over thirty-five years.d.Food may cause forty percent of cancer in world.3.How has science done something harmful to mankind?a.Because of science , diseases caused by polluted food haven been virtually eli minated.b.It has caused a lack of information concerning the value of food.c.Because of the application of science,some potentially harmful substances have been added to food.d.The scientists have preserved the color of meats,but not of vegetables.4.What are nitrates used for?a.They preserve flavor in packaged foods.b.They preserve the color of meats.c.They are the objects of research.d.They cause the animals to become fatter.5.The word 'carcinogenic' most nearly means '_____'.a.trouble-makingb.color-retainingc.money-makingd.cancer-causing5/200答案：cacbd6/200As the pace of life continues to increase ,we are fast losing the art of relaxat ion. Once you are in the habit of rushing through lift,being on the go from morn ing till night, it is hard to slow down. But relaxation is essential for a healt hy mind and body.Stress is an natural part of everyday lift and there is no way to avoid it. In f act ,it is not the bad thing it is often supposed to be .A certain amount of str ess is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime ma terial for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chem ically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The c rises we meet today are unlikely to be so extreme,but however little the stress, it involves the same response. It is when such a reaction lasts long,through con tinued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Sin ce we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it.1.People are finding less and less time for relaxing themselves because_____.a.they do not know how to enjoy themselvesb.they do not believe that relaxation is important for healthc.they are travelling fast all the timed.they are becoming busier with their work2.According to the writer ,the most important character for a good manager is hi s ________.a.not fearing stressb.knowing the art of relaxationc.high sense of responsibilityd.having control over performance3.Which of the follwing statements is ture?a.We can find some ways to avoid stressb.Stress is always harmful to peoplec.It is easy to change the hagit of keeping oneself busy with work.d.Different people can withstand different amounts of stress4.In Paragraph 3, "such a reaction" refers back to_______.a."making a choice between 'flight' or 'fight'"b."reaction to stress both chemically and physically"c."responding to crises quickly"d."losing heart at the signs difficulties"5.In the last sentence of the passage,"do so " refers to ______.a."expose ourselves to stress"b."find ways to deal with stress"c."remove stress from our lives"d."established links between diseases and stress"6/200答案：dadbcIn the 1960s, many young Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all of the people in the U.S. epual. Some of them decided to "drop out" of American society and form their own societ ies . They formed utopian communities , which they called "communes," where they could follow their philosophy of "do your own thing." A group of artists founde d a commune in southern Colorado called "Drop City." Following the ideas of phil osopher and architect Buckminster Fuller they built domeshaped houses from piece s of old cars. Other groups, such as author Ken Kesey's Merry Pranksters, the fo llowers fo San Francisco poet Steve Gakin, and a group that called itself the Ho g Farm, lived in old school huses and traveled around the United States. The Hog Farm become famous when they helped organize the Woodstock Rock Festival in 196 9. Steve Gaskin's followers tried to settle down on a farm in Tennessee, but the y had to leave when some members of the gruop were arrested for growing marijuan a.Not all communes believed in the philosophy of "do you own thing," however . Twi n Oaks , a commune founded in Virgiania in the late 1960s, was based on the idea s of psychologist B.F.Skinner. The people who lived at Twin Oaks were carefully controlled by Skinner's "conditioning" techniques to do things that were good fo r the community. In 1972, Italian architect Paolo Soleri began to build Arcosant i, a utopian city Arizsona where 2500 people will live closely together in one large building called an "archology" Soleri believes that people must live closel y together so that they will all become one.1.Why did some young Americans decide to "drop out" of scoiety during the 1960s?a.They were not satisfied with American society.b.They wanted to grow marijuana.c.They wanted to go to the Vietnam War.d.They did not want all people to be equal.2.Where did the members of the Hog Farm commune live?a.In dome-shaped houseb.In old school husesc.On a farm inTennesseed.In an archology in Arizona3.Who gave the people of Drop City the idea to bulid dome-shaped house?a.Paolo Solerib.B.G.Skinnerc.Steve Gaskind.Buckminster Fuller4.What was the Twin Oaks commune base on ?a.The philosophy of "do your own thing"b.Virginaia in the late 1960sc.The ideas of psychologistd.The belief that people must live closely togerher.5.What is an "archology"?a.A person who studies archaeologyb.A large building where people live closely togetherc.A city in A rizonad.A technique to contorl people7/200答案：abdcb8/200There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of en vironment in which he is reared. If an individual is handicapped envionmentally , it is likely that his brain will fail to develop and he will never attain the le vel of intelligence of which he is capable.The importance of environment in determining an individual's intellingence can b e demonstrated by the case history of the identical twins, Peter and Mark X. Bei ng identical, the twins had identical brains at birth, and their growth processe s were the same. When the twins were three months old , their parents died, and they were placed in separate foster homes. Peter was reated by parents of low in telligence in an isolatedcommunity with poor educational pooprtunities.Mark wasreared inthe home of well-to-do parents who had been to college. He was read to as a child , sent to good schools, and given every opportunity to be stimulated intellectually.This enviromental difference continued until the twins were in th eir late teens, when they were giben tesets to measure their intelligence. Mark' s I.Q. was 125, twenty-five points higher than the average and fully forty point s higher than his identical brother. Given equal opportunities , the twins , hav ing identical brains,would have tested at roughly the same level.1.This selection can best be titled_________.a.Measuring Your Intelligenceb.Intelligence and Environmentc.The Case of Peter and Markd.How the brain Influences Intelligence2.The beststatement of the main idea of this passage is that _____.a.human brains differ considerablyb.the brain a person is born with is improtant in determining his intelligencec.environment is crucial in determining a person's intelligenced. persons having identical brains will have roughly the same intelligence3.According to the passage , the average I.Q.is _____.a.85b.100c.110d.1254.The case history of the twins appears to support the conclusion that _____.a.individual with identical brains seldom test at same levelb.an individual's intelligence is determined only by his enviromentck of opportunity blocks the growth of intelligenced.changes of enviroment produce changes in the structure of the brain5.This passage suggests that an individual 's I.Q.______.a.can be predicted at birthb.stays the same throuthout his lifec.can be increased by educationd.is determined by his childhood8/200答案：bcbcc9/200As she walked round the huge department store,Edith reflected how difficult it w as to choose a suitable Christmas present for her father.She wish that he was as easy to please as her mother, who was always delighted with perfume Besides,shoppong at this time of the year was a most disgreeable experience :peo ple trod on your toes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attracive t ies were on display. "They are real silk," the assistant assured her, trying to tempt her. "Worth double the price." But edit knew from past experience that her choice of ties hardly ever pleased her father.She moved on reluctantly and then quite by chance, stopped where a small crowd o f man had gathered round a counter. She found some good quality pipes on sale-----and the prices were very reasonable. Edith did not hesitate for long : althoug h her father only smoked a pipe occasionally, she knew that this was a present w hich was bund to please him.When she got home,with her small well-chosen present concealed in her handbag, h er parents were already at the supper table. Her mother was in an especially che erful mood, "Your father has at last to decided to stop smoking." She informed h er daughter.1.Edith's father _______.a.did not like presentb.never got presentc.preferred tiesd.was difficult to choose a present for2.The assistant spoke to Edith because she seemed_______.a.attractiveb.interested in tiesc.tiredd.in need of comfort3.Edith stopped at the next counter_________.a.puroselyb.suddenlyc.unwillinglyd.accidentally4.Edith's father smoked a pipe_______.a.when he was obligedb.on social occasionsc.from time to timed.when he was delighted5.Shopping was very disagreeable at that time of the year because_______.a.coustomers trod on each other's toesb.coustomers poked each other with their elbowsc.customers knocked each otherd.customers were doing their shopping in a great hurry9/200答案：dbdcd10/200If the population of the earth goes on increasing at its present rate, there wil l eventually not be enough resources left to sustain life on the planet.By the m iddle of the 21st century,if present trends continue, we will have used up all t he oil that drives our cars,for example.Even if scientists develop new ways of f eeding the human race,the crowded conditions on earth will make it necessary for lus to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however,has recently been suggested by American scientist, Profes sor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted it wi ll be possible to change the atmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the e arth and there is only a tiny amount of water there.Sagan proposes that algae organisms that can live in extremely hot or cold atmos pheres and at the same time produce oxygen,should be bred in condition similar t o those on Venus.As soon as this has been done, the algae will be placed in smal l rockets. Spaceship will then fly to Venus and fire the rockets into the atmosp here .In a fairly short time, the alge will break down the carbon dioxide into o xygen and carbon.When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the r ain will eventually fall and in a few years something like earth will be reprodu ced on Venus.1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.a.foodb.oilc.spaced.resources2.Carl Sagan believes that Venus might be colonized from earth because _____a.it might be possible to change its atmosphereb.its atmosphere is the same as the earth'sc.there is a good supply of water on Venusd.the days on Venus are long enough3.On Venus there is a lot of ________.a.waterb.carbon dioxidec.carbon monoxided.oxygen4.Algae are plants that can____.a.live in very hot temperaturesb.live in very cold temperaturesc.manufacture oxygend.all of the above5. Man can land on Venus only when_______.a.the algae have done their workb.the atmosphere becomes coolerc.thereis oxygend.it rains there10/200答案：cabdd11/200What is your favourite colour? Do you like yellow , orange ,red? If you do ,you must be an optimist, a leader, an active person who enjoys life, people and exci tement. Do you prefer greys and blues? Then you are probably quiet,shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is wha t psychologists tell us, and they should know,because they have been seriously s tudying the meaning of colours preference, as well as the effect that colours ha ve on human beings. They tells us, among other facts,that we do not choose our f avourite clour as we grow up----we are born with our preference.If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.Colours do influence our moods----there is no doubt about it .A yellow room make s most people feel more cheerful and more relaxed than a dark green one; and a r ed dress brings warmth and cheer to the saddest winter day. On the other hand ,b lack is depressing. A black bridge over the Thames River, near London, used to b e the scene of more suicides than any other bridge in the area ----until it was repainter green.The number of suicide attempts immediately fell sharply ;perhaps it would have fallen even more if the bridge had been done in pink or baby blue.Light and bright colours make people not only hppier but more active. It is an e stablished fact that factory workers work better,harder ,and have fewer accident s when their machines are painted orange rather than black or grey.1."You would rather follow than red" means_______.a.you don't like to follow othersb.you would be a member rather than a leaderc.you would be afraid of following othersd.you would like to be a leader rather than a follower2.If one enjoys life, one is sure to prefer________.a.red to yellowb.blue to orangec.red to greyd.blue to yellow3."They tell us, among other facts,that we don't choose our favourite colours as we grow up." "Among other facts" means______.a.besides other factsb.in regard to other factsc.not considering other factsd.according to other facts4.Which of the following is facts?a.People's preference of one colour to another is instinctb.People's preference of one colour to another is acquired as they grow up.c.More people happen to love brown because they saw something brown when they we re bornd.Colours have little influence on our moods。

9. Biological Clocks Every living thing has an inner biological clock that controls behaviour. The clock works all the time, even when there are no outside signs to mark the passing of the time. The biological clock tells the plants when to form flowers and when the flowers should open. It tells insects when to leave the protective cocoon and fly away. And it tells animals when to eat, sleep and wake. It controls body temperature, the release of some hormones, and even dreams. These natural daily events are called circadian rhythms.
Man has known about them for thousands of years. But the first scientific observation of circadian rhythms was not made until 1792. In that year, French astronomer, Jean-Jacques d’ortous de Mairan, noted that one of his plants opened its leaves at the same time every morning, and closed them at the same time every night. The plant did this even when he kept it in a dark place all the time.
Later scientists wondered about circadian rhythms in humans. They learned that mans biological clock actually keeps time with a day of a little less than 25 hours instead of the 24 hours on a man-made clock.
About four years ago American doctor, Eliot Weitzman, established a laboratory to study how our biological clock works. The people in his experiments are shut off from the outside world. They are free to listen to and live by their circadian rhythms. Dr. Weitzman hopes his research will lead to effective treatments for common sleep problems and sleep disorders caused by aging and mental illness.
The laboratory is in the Montefiore Hospital in Now York City. It has two living areas with three small rooms in each. The windows are covered, so no sunlight or moonlight comes in. there are no radios or television receivers. There is a control room between the living areas. It contains computers, oneway cameras and other electronic devices for observing the person in the living area. The instruments measure heartbeat, body temperature, hormones in the blood, other substances in the urine and brain waves during sleep.
A doctor or medical technician is on duty in the control room 24 hours a day during an experiment. They do not work the same time each day and are not permitted to wear watches, so the person in the experiment has no idea what time it is.
In the first four years of research, Dr. Weitzman and his assistant have observed 16 men between the ages of 21 and 80. The men remained in the laboratory for as long as six months. Last month, a science reporter for The New York Times newspapers, Dava Sobol, became the first woman to take part in the experiment. She entered the laboratory on June 13th and stayed for 25 days. Miss Sobol wrote reports about the experiment during that time, which were published in the newspaper.
Scientists have discovered a tiny group of cells in the brain that act as a clock to control many bodily activities. The discovery was made by doctors at Harvard University. They began by studying the clocklike group of cells in the brain of monkeys.
Dr. Martin Moore Ede and Dr. Ralph Leidick recorded when during the day the monkeys ate, drank, and slept. They found that most of the monkeys did the same things at about the same time each day. Then the doctors operated on the monkeys. They destroyed the tiny group of brain cells which they believed controlled the timing of activities.
After the operation they found that the animals ate, drank, and slept the same amounts as before. But they did these things at very different times each day. There no longer seemed to be a clock within them that told them when it was time to eat, drink or sleep. Scientists could not do the same kinds of experiments with humans. But they were able to find evidence of a similar group of cells in the human brain.
The cells lie directly above the place where the two optic nerves cross. There are only about 20,000 cells in the group. All of them together create a mass less than one fourth of a millimeter wide.
