Passage 3As the pace of life continues to increase, we are fast losing the art of relaxation. But relaxation is __1__ for a healthy mind and body.Stress is a natural part of everyday life and there is no way to __2__ it. In fact, it is not the bad thing as it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of __3__ 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 __4__ are obviously prime material for managerial responsibilities. Others lose heart at the first sight of __5__ difficulties. When exposed to stress, in whatever form, we react both physically and __6__. In fact we make choice between “flight or fight” and in more __7__ days the choices made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress, it involves the same __8__. It is when such a reaction lasts long, through continued __9__ to stress, that health becomes endangered. Since we cannot __10__ stress from our lives it would be unwise to do so even if we could, we need to find ways to deal with it.Passage 4As is known to all, the organization and management of wages and salaries are very complex. Generally speaking, the Accounts Department is __1__ for calculations of pay, while the Personnel Department is interested in discussions with the employees about pay.If a firm wants to __2__ a new wage and salary structure, it is essential that the firm should decide on a __3__ of job evaluation and ways of measuring the performance of its employees. In order to be __4__, that new pay structure will need agreement between Trade Unions and employers. In job evaluation, all of the requirements of each job are defined in a detailed job description. Each of thoserequirements is given a value, usually in “points”, which are __5__ together to give a total value for the job. For middle and higher management, a special method is used to evaluate managers on their knowledge of the job, their responsibility, and their __6__ to solve problems. Because of the difficulty in measuring management work, however, job grades for managers are often decided without __7__ to an evaluation system based on points.In attempting to design a pay system, the Personnel Department should __8__ the value of each job with these in the job market. __9__, payment for a job should vary with any differences in the way that the job is performed. Where it is simple to measure the work done, as in the works done with hands, monetary encouragement schemes are often chosen, for __10__ workers, where measurement is difficult, methods of additional payments are employed.Passage 5Americans are proud of their variety and individuality, yet they love and respect few things more than a uniform. Why are uniforms so __1__ in the United States?Among the arguments for uniforms, one of the first is that in the eyes of most people they look more __2__ than civilian（百姓的）clothes. People have become conditioned to __3__ superior quality from a man who wears a uniform.The television repairman who wears a uniform tends to __4__ more trust than one who appears in civilian clothes. Faith in the __5__ of a garage mechanic is increased by a uniform. What an easier way is there for a nurse, a policeman, a barber, or a waiter to __6__ professional identity（身份）than to step out of uniform? Uniforms also have many __7__ benefits. They save on other clothes. They save on laundry bills. They are often more comfortable and more durable than civilian clothes.Primary among the arguments against uniforms is their lack of variety and the consequent loss of __8__ experienced by people who must wear them. Though there are many types of uniforms, the wearer of any particular type is generally stuck with it,without __9__, until retirement. When people look alike, they tend to think, speak, and act __10__, o n the job at le a st.Passage 6Britain is not just one country and one people; even if some of its inhabitants think so. Britain is, in fact, a nation which can be divided into several __1__ parts, each part being an individual country with its own language, character and cultural __2__. Thus Scotland, Northern Ireland and Wales do not claim to __3__ to “England” because their inhabitants are not __4__ “English”. They are Scottish, Irish or Welsh and many of them prefer to speak their own native tongue, which in turn is __5__ to the others.These cultural minorities(少数民族) have been Britain’s original inhabitants. In varying degrees they have managed to __6__ their national characteristics, and their particular customs and way of life. This is probably even truer of the __7__ areas where traditional life has not been so affected by the __8__ of industrialism as the border areas have been. The Celtic races are said to be more emotional by nature than the English. An Irish temper is legendary. The Scots could rather __9__ about their reputation for excessive thrift and prefer to be remembered for their folk songs and dances, while the Welsh are famous for their singing. The Celtic __10__ as a whole produces humorous writers and artists, such as the Irish Bernard Shaw, the ScottishPassage 8Psychologists take opposing views of how external rewards, from warm praise to cold cash, affect motivation and creativity. Behaviorists, who study the relation between actions and their consequences, argue that rewards can __1__ performance at work and school. Cognitive( 认识派的) researchers, who study various aspects of mental life, maintain that rewards often destroy creativity by encouraging dependence on __2__ and gifts from others.A coeducational(男女合校的) school offers children nothing less than a tree version of society in miniature(缩影). Boys and girls are given the 1 to get to know each other, to learn to live together from their earliest years. They are put in a position where they can compare themselves with each other in terms of 2 ability, athletic achievement and many of the extracurricular activities which are part of school life. What a practical 3 it is (to give just a small example) to be able to put on a school play in which the male parts will be taken by boys and the female parts by girls! What nonsense coeducation makes of the argument that boys are cleverer than girls or vice versa. When 4 , boys and girls are made to feel that they are a race apart. In a coeducational school, everything falls into its 5 place.The greatest contribution of coeducation is 6 the healthy attitude to life it encourages. Boys don’t grow up believing that women are 7 creatures. Girls don’t grow up imagining that men are romantic heroes. Years of living together at school remove illusions of this kind. The awkward stage of adolescence brings into sharp focus some of the physical and 8 problems involved in growing up. These can better be 9 in a coeducational environment. When the time comes for the pupils to leave school, they are fully prepared to 10 society as well-adjusted adults. They have already had years of experience in coping with many of the problems that face men and women.Passage 13The anthropologist (人类学家) Clifford Geertz defines culture as a “historically transmitted pattern of meanings embodied in symbols by 1 of which men can communicate, perpetuate and develop their own knowledge about and attitudes towards life.”Why is it important that you 2 about other cultures? There are a number of reasons. Some may do it 3 because they find fascinating the different ways that people think, speak, act, evaluate, and communicate. But let me assume that you are a more pragmatic sort of person, and are 4 in the “cash value” of a course like this — apart, that is, from the grade you will receive at the end of it. What is a class like this good for? Let me make a couple of suggestions on how what you learn in this class may prove 5 to you in the future:Business: Geert Hofstede’s excellent book on culture is 6 not primarily out of academic theory, but out of his study of the practical problems faced by one particular modern corporation (IBM), which exists across national and cultural 7 . In the world we live in, understanding 8 in general and also specific individual cultures in particular can make the difference between success and failure in the global market and economy.Politics and Diplomacy: If your career goal involves anything that relates to international politics and diplomacy, then understanding other cultures is 9 .Neighbors: If none of these previous factors 10 you, then you can just look at this class as a lesson in good neighborliness in the global village.Passage 14A pioneering study into the effects of a mother’s fat intake during pregnancy on her child’s health when he or she grows up is being launched at the University of Southampton.The research will investigate whether the type and amount of fat a mother eats during pregnancy 1 the risk of heart disease, 2 high blood pressure, in her child when he or she reaches adulthood.Although the link between high fat diets and high blood pressure is well known, there has been 3 research into the connection between a woman’s diet and her child’s risk of hypertension (高血压).The study, which is 4 by the British Heart Foundation, is led by Dr Graham Burdge, British Heart Foundation Professor of Cardiovascular Science.The award of this 5 grant is part of a ￡3.5 million boost for heart research in the UK by the British Heart Foundation. The charity’s special grants are made to fund research into the causes, prevention, 6 and treatment of heart disease, the UK’s biggest killer.Dr Burdge says, “The type and amount of fat in our diet has 7 during the past 50 years. Pregnant women 8 the same diet as the rest of us, but we know very little about the 9 of these changes in dietary (饮食的) fat on the development and future health of their children. We hope that the 10 of this study will help to develop recommendations for pregnant women about how much fat they should eat and what types of fat they should avoid.”Passage 15Major retailers and car manufacturers have slashed (削减) their marketing budgets in the six months to October, 2008, as the financial crisis has taken its toll, while supermarkets have __1__advertising spending in a battle to prove that they offer the most ___2__ prices.According to new research undertaken for The Daily Telegraph by Nielsen Media Research, in the six months to September 30, 2008, Marks & Spencer’s advertising spend fell 20.3 pc to ￡25.3 m, __3___ with the same period in 2007.While the retailer has spent heavily on a campaign __4__ celebrities in the past two years, it is understood to be cutting back on celebrity spending in 2009. The retailer is, however, still the UK’s 25th largest spender on advertising, __5__ being at 17th place in the six months to September 30, 2007.Car manufacturers have also significantly ___6__ back on marketing spending, believed to be a result of the financial crisis. According to Nielsen, Ford spent ￡26.6m in the six months to September 30, 2008, down 21pc from the same period last year. Vauxhall also ___7__ spending by 15.6pc in the period to ￡26.5m.For supermarkets, however, a significant increase in advertising spending, it appears, is a ___8___ as they seek to woo (追求) increasingly price __9__ customers. The leading supermarkets have __10__ an aggressive price war in the past six months as consumers have been faced with news of higher food prices.Passage 16Teddy bears have been around since 1902. The teddy bear came to being when President Theodore Roosevelt refused to 1 a black bear held captive by his hunting party. Also worth noting is that President Roosevelt’s refusal to shoot this captive bear became a very popular political cartoon by Cliff Barryman.A Brooklyn shopkeeper was 2 by the cartoon. The shopkeeper then asked President Rosevelt for 3 to name a toy bear “Teddy”. Thus became the creation of the teddy bear.It is also worth 4 that the teddy bear was born in Germany between 1902 and 1903.The first teddy bears did not have cuddly faces or smiles, in fact, the first teddy bears had expressions which could best be described as 5 . Teddy bears were also quite stiff, the 6 arms and legs and soft, plush bodies came much later.Now teddy bears are still the number one item to give babies as their first toy, the prize to win your girl on your first date, and most 7 , the toy of choice for law enforcement to give to children in sad, unsafe situations to help them calm down and feel safe.The market for collectible teddy bears has seen significant 8 in the last several years. A collectible teddy bear is very different than the typical store bought teddy that you might give a child. The industry 9 collectible teddy bears as hard, not floppy, and fully jointed (meaning arms, legs, and head are moveable). The artists however, also determine collectibles. Steiff teddy bears and others have a very high collectible 10 .Passage 17Hungry prehistoric hunters, not climate change, drove elephants to extinction during the Pleistocene era, new research suggests.At least 12 kinds of elephants 1 to roam the African, Eurasian, and American continents. Today, only two 2 of elephants are left in South Asia and sub-Saharan Africa. One theory for this dramatic demise holds that rapid climate shifts at the end of the most recent major ice age, some 10,000 years ago, 3 vegetation and broke up habitats, causing the death of those unable to adapt to the new conditions. Another 4 blames prehistoric humans, whose improved weapons and hunting techniques allowed them to wipe out whole herds of elephants.To help 5 the debate, archaeologist Todd Surovell of the University of Wyoming, Laramie, and colleagues tested two assumptions. If humans caused the elephant and mammoth extinctions, Surovell reasoned, the timing of the die-offs in 6 regions should match human expansion into those regions. On the contrary, if the extinction was 7 to climate change, elephants should remain in regions 8 colonized by humans and would only begin to die off once climate change occurred.The team tested both theories by analyzing where and when elephants were killed. In all, the study included 41 archaeological sites on five continents. The researchers found that, as humans 9 out of Africa, they left a trail of dead elephants behind them. The creatures disappear from the fossil record of a region once it became colonized by humans. Modern elephants survived in refuges 10 to humans, such as tropical forests, says Surovell.Passage 18There have been claims that warming on Mars and Pluto are proof that the recent warming on Earth is caused by an increase in solar activity, and not by greenhouses gases. But we can say with 1 that, even if Mars, Pluto or any other planets have warmed in recent years, it is not due to 2 in solar activity.The Sun's energy output has not increased since direct 3 began in 1978. If increased solar output really was 4 , we should be seeing warming on all the planets and their moons, not just Mars and Pluto.Our solar system has eight planets, three dwarf planets and quite a few moons with at least a 5 atmosphere, and thus a climate of sorts. Their climates will be 6 by local factors such as orbital variations, changes in reflectance (反射率) and even 7 eruptions, so it would not be surprising if several planets and moons turn out to be warming at any one time.However, given that a year on Mars is 8 two Earth years long, and that a year on Pluto lasts for 248 Earth years, it is rather early to start 9 conclusions about long-term climate trends on the outer bodies of the Solar System.What do we know? Images of Mars suggest that between 1999 and 2005, some of the frozen carbon dioxide that 10 the south polar region turned into gas. This may be the result of the whole planet warming.。

Passage 1In recent years, more and more foreigners are involved in the teaching programs of the United States. Both the advantages and the disadvantages 47 using foreign faculty in teaching positions have to be 48 , of course. It can be said that the foreign background that makes the faculty member from abroad an asset also 49problems of adjustment, both for the university and for the individual. The foreign research scholar usually isolates himself in the laboratory as a means of protection; 50, what he needs is to be fitted to a highly organized university system quite different from 51 at home. He is faced in his daily work with differences in philosophy, arrangements of courses and methods of teaching. Both the visiting professor and his students 52 a common ground in each other’s cultures, some concept of what is already in the minds of American students is 53 for the foreign professor. While helping him to adapt himself to his new environment, the university must also 54 certain adjustments in order to take full advantage of what the newcomer can 55 . It isn’t always known how to make creative use of foreign faculty, especially at smaller colleges. This is thought to be a 56 where further study is called for. The findings of such a study will be of value to colleges and universities with foreign faculty.It seems you always forget—your reading glasses when you are rushing to work, your coat when you are going to the cleaners, your credit card when you are shopping...Such absent-mindedness may be 47 to you; now British and German scientists are developing memory glasses that record everything the 48 sees.The glasses can play back memories later to help the wearer remember things they have forgotten such as where they left their keys. And the glasses also 49 the user to "label" items so that information can be used later on. The wearer could walk around an office or a factory identifying certain 50 by pointing at them. Objects indicated are then given a 51 label on a screen inside the glasses that the user then fills in.It could be used in 52 plants by mechanics looking to identify machine parts or by electricians wiring a 53 device.A spokesman for the project said: "A car mechanic for 54 could find at aglance where a part on a certain car model is so that it can be identified and repaired. For the motorist the system could 55 accident black spots or dangers on the road."In other cases the glasses could be worn by people going on a guided tour, 56 points of interest or by people looking at panoramas where all the sites could be identified.A sunflower is a sunflower. A mobile phone is a mobile phone. But can you 47 the two to do something for your local 48 ?It may well be possible. When you have finished with your mobile phone you will be able to 49 it in the garden or a plant pot and wait for it to flower.50 , a biodegradable (生物可降解的)mobile phone was introduced by scientists. It is hoped that the new type of phone will encourage 51 to recycle.Scientists have come up with a new material over the last five years. It looks like any other 52 and can be hard or soft. and able to change shape. Overtime it can also break down into the soil without giving out any toxic 53 . British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it 54 nitrates(硝酸盐). These feed the seed and help the flower grow.Engineers have designed a small 55 window to hold the seed. They have made sure it only grows when the phone is thrown away."We've only put sunflower seeds into the covers so far. But we are working with plant 56 to find out which flowers would perform best. Maybe we could put roses in next time," said one scientist.Blue is the world's favorite color. It is also the color most often 47 with intellect and authority.Most uniforms are blue. In Greek and Roman mythology, blue is the color of sky gods. In the Old Testament, God is 48 by deep blue. Blue and turquoise (青绿色)are represented by the Islamic religion. It is the 49 color in the mosques of the world.Blue symbolizes truth, peace and cooperation. It is the color of the flag of the United Nations and of Europe. As the coolest color of the spectrum, it is the hue mostlikely to have a receding effect. As in the skies and water that 50 us, blue is seen as a peaceful and 51 color. Blue light has seen to 52 blood pressure by calming the nervous system hence relaxing the body and mind. Blue creates large airy spaces. It makes rooms bigger.The wrong shade of blue can be uncomfortable. It can also be cold and sterile(枯燥的)unless 53 with warmer colors.Light and soft blue makes us feel quiet and protected from the bustle(喧闹)and 54 of the day. Blue bedrooms are restful. Blue bath rooms are appropriately watery. Blue 55 depth with greens and reds. Dark blue represents the night making us calm. Its apparently calming effect makes it the perfect tone for the quieter 56 of your living space.Perhaps like most Americans you have some extra pounds to 47 . You may even have tried a fad diet or two, but found yourself right back where you started. The key to weight loss is regular 48 activity. And surprisingly, you don't have to give up eating or make the gym your second home to see long-term, 49 effects.You body needs a certain amount of energy to maintain basic 50 such as breathing, blood circulation and digestion. The energy required to keep your organs functioning is referred to as the resting or basal metabolic rate.Any time you are active, 51 energy is required. It is obtained from glycogen and fat stored in the blood, liver, and muscles. The key to losing weight is to draw on the fat rather than on the carbohydrate reserves.Which of the two energy sources you use depends on the intensity and 52of your activity. The higher the intensity, the more your body will pull from the stored carbohydrates. The lower the intensity, the more your body will 53 on fat as its fuel.Aerobic exercise is most 54 for weight loss. When you perform aerobic activities you 55 contract large muscle groups such as your legs and arms. Walking, running, rollerblading, swimming, dancing, and jumping jacks are all forms of aerobic activity.Surprisingly, if your aerobic activity is low to moderately intense and of long duration, you will burn more fat than if you had 56 in a short burst ofhigh-intensity exercise. In short, a brisk 30-minute walk will burn fat while a100-yard sprint will burn glycogen.Passage 6budgets in the six months to October, 2008, as the financial crisis has taken its toll, while supermarkets have 11 advertising spending in a battle to prove that they offer the most 12 prices.According to new research undertaken for The Daily Telegraph by Nielsen Media Research, in the six months to September 30, 2008, Marks & Spencer’s advertising spend fell 20.3pc to ￡25.3m, 13 with the same period in 2007.While the retailer has spent heavily on a campaign 14 celebrities in the past two years, it is understood to be cutting back on celebrity spending in 2009. The retailer is, however, still the UK’s 25th la rgest spender on advertising, 15 being at 17th place in the six months to September 30, 2007.Car manufacturers have also significantly 16 back on marketing spending, believed to be a result of the financial crisis. According to Nielsen, Ford spent ￡26.6m in the six months to September 30, 2008, down 21pc from the same period last year. Vauxhall also 17 spending by 15.6pc in the period to ￡26.5m.For supermarkets, however, a significant increase in advertising spending, it appears, is a 18 as they seek to woo (追求) increasingly price- 19 customers. The leading supermarkets have 20 an aggressive price war in the past six months as consumers have been faced with news of higher food prices.Undoubtedly the globe is getting hotter and hotter. The unavoidable questions are: How much responsibility shall we take for warming, and are we 47 to stop the destruction by limiting our insatiable 48 for natural fuels?It seems that global warming is too _49_ to be worried about, or too unpredictable. The computer_50_ cannot define what the weather is like next week. In cold winter day it might be considered that a little warming would be a fair thing. And doubtlessly: Alarming about_51_ alteration may sound like an environmentalist frightening strategy, aiming to urge humans to walk and keep the world cleaner.However, based on the data collected by scientists, bad news are brought to our living media.From California to the snowy peaks of China, the air is heating up right now, and the globe is being fast warmed, the _52_ has increased by 1 ℉ compared with the past century. In addition, some parts like remote places have been in a much hotter state. The results aren't satisfactory, ice being _53_ , rivers running dry, and coasts being _54_ , threatening villages and cottages.The 55 are gradually occurring without any obvious phenomenon. But they shouldn't slip our mind, because they can pose as a great potential threat to the 56 world.The way you go about purchasing an article or a service can actually 47 you money or can add to the cost. Take the 48 example of a hairdryer. If you are buying a hairdryer, you might think that you are making the 49 buy if you choose one whose look you like and which is also the cheapest 50 price. But when you get it home you may find that it takes twice as long as a more expensive51 to dry your hair. The cost of the electricity plus the cost of your time could well make your hairdryer the most expensive one of all。

However, these beasts of the sea do display a vast range of highly __28__ behaviors that appear to be driving their genetic development.The word "culture" comes from the Latin "colere," which __29__ means "to cultivate." In other words, it refers to anything that is __30__ or learnt, rather than instinctive or natural. Among human populations, culture not only affects the way we live, but also writes itself into our genes, affecting who we are.

As such, different populations of killer whales have had to learn different hunting techniques in order to gain the upper hand over their local prey （猎物）.

Americans view five hours of TV each day, and while we know that spending so much time sitting 36 can lead to obesity (肥胖症) and other diseases, researchers have now quantified just how 37 being a couch potato can be.In an analysis of data from eight large 38 published studies, a Harvard-led group reported in the Journal of the American Medical Association that for every two hours per day spent channel 39 , the risk of developing Type 2 diabetes(糖尿病) rose 20% over 8.5 years, the risk of heart disease increased 15% over a 40 , and the odds of dying prematurely 41 13% during a seven-year follow-up. All of these 42 are linked to a lack of physical exercise. But compared with other sedentary(久坐的) activities, like knitting, viewing TV may be especially 43 at promoting unhealthy habits. For one, the sheer number of hours we pass watching TV dwarfs the time we spend on anything else. And other studies have found that watching ads for beer and popcorn may make you more likely to 44 them.Even so, the authors admit that they didn’t compare different sedentary activities to 45 whether TV watching was linked to a greater risk of diabetes, heart disease or early death compared with, say, reading.（五）A.announcingB.beneficialC.challengesmitmentponentF.contestsG.critically H.develop I.distributingJ.enhance K.entitled L.potentialM.properly N.qualified O.retainThe U.S. Department of Education is making efforts to ensure that all students have equal access to a quality education.

• 较难的一个例子：Husbands and children now do some of these jobs, a ____ that has changed the target market for many products. (06-12) 这里可以用两种判断方法 来判断横线处所填词的词性。第一种方法，用句子结构来判断，前面一句话，Husbands and children now do some of these jobs，这是一个完整的句子，主语husbands and children，谓语动词DO，宾语Some of these jobs；后面的that引导的是一个同位语从 句，它所修饰的中心词就是a后面需要填的词，而定语从句的中心词是名词，所以横线处 应填一个名词。第二种方 法，根据刚才所说的“a + 名词”的语法规则来判断，横线处应 该填一个名词，而且是一个可数名词的单数形式。正确答案是situation。这句话的意思是 “丈夫和孩子现在也做一些 这样的工作了，这种情况就改变了许多产品的目标市场。”
• 2. 当出现“一个完整的句子 + ，____ + 名词/介词”的结构时，逗号后 边的部分是伴随状语，表示伴随状态或者表示原因，应当填动词加ING形 式或动词加ED形式。当这个动词与句子主语是主动关 系，填动词加ING形 式，当两者是被动关系，填动词加ED形式。
• 举例说明：
• The rainfall is increased across south america, ___ floods to peru. (06-6) 根据独立主格结构原则，应该填动词ing或动词ed，选项中只有 bringing符合要求。从意思来看，bring“带来”与rainfall“降雨”之 间 是主动关系，即“the rainfall brings floods”，所以用bringing无论从 意思上还是结构上都符合要求。

大学英语四级_选词填空_技巧篇
大学英语四级选词填空技巧篇1）阅读选项，词性分类仍然要―先题后文在定位‖，但这里―先题‖不是要找关键词，而是要先对15个选项―辨性‖仔细阅读选项，根据词性把每个单词进行分类归纳。
如名词、动词、形容词、副词、介词、连词各有几个选项。
动词归类要细分为v，ved, ving。
因为一个空可以填动词，但填原形还是过去式还是ing形式要自己根据语法判断。
2）细读首句，抓住中心首先要抓住文章首句，迅速找到文章的主题词或主题。
和完型填空一样，一般文章第一句不设空格，以便让读者知道本文的相关主题词或主题。
3）瞻前顾后，谨慎选择根据文章前后的语法关系判断应填入的词性，大大缩小选择范围。
当一个空可以填入好几个相同词性的词时，则根据上下文逻辑意义；如果均能说得通时，要注意近义辨析。
或留到最后，等范围缩小到最小时再轻松收尾。
即传统阅读所说的，首遍不行无所谓，文章看完再收尾。
解题技巧1）首先要辨性（辨别词性）a. 不认识的单词看词缀（见后面附表）b. 认识的单词要注意词性的单一性和多样性比如：must，most均可做名词do the most you canc. 动词归类要细分为v，ved, ving。
因为一个空可以填动词，但填原形还是过去式还是ing 形式要自己根据语法判断。
甚至动词分词形式还可以做定语。
2）一个单词有多个词性时，要在不同分类中都标出。
3）如果选项中出现一组近义词或反义词时，往往有一个是干扰选项，它注重考察的是词汇的精确理解，要求考生分析清楚其细微的区别。
4）如何判断原文空缺处所需单词的词性：①动词：a）前后都是名词短语，中间一般为动词（时态看前后文）。
b) 一个句子有且只有一个谓语动词c）一个完整的句子之后再跟逗号，后面一般是非谓语动词短语。
②名词：a. 名词主要做主语、宾语。
b. 形容词或名词都可以修饰名词例：The hot, humid (潮湿的) air over the ocean causes severe ___49___ thunderstorms.（49可能是形容词，也可能是名词修饰thunderstorms）c. 限定词（the, this, that, a, my之类）后必有名词d. 谓语动词前必有名词或名词性质的主语e. 介词后面必有名词③. 副词修饰形容词或动词附录：四级常用后缀1. 名词后缀1)-or/er/ess/crat/cis:做某件事情或职业的人或物：worker, debtor2)-acy, 表示―性质，状态，境遇‖ democracy, accuracy, diplomacy3)-ance, -ence表示―性质，状况，行为，过程，总量，程度‖ importance, diligence, difference, obedience4)-ancy, -ency, 表示―性质，状态，行为，过程‖ frequency, urgency, efficiency,5)-bility, 表示―动作，性质，状态‖ possibility, flexibility, feasibility,6)-dom, 表示―等级，领域，状态‖ freedom, kingdom, wisdom7)-hood, 表示"资格，身份, 年纪，状态" childhood, manhood, falsehood8)-ion, -sion, -tion, -ation, -ition, 表示―行为的过程，结果，状况‖ action, solution, conclusion, destruction, expression_r, correction9)-ism, 表示―制度，主义，学说，信仰，行为‖ socialism, criticism, colloquialism, heroism10)-ity, 表示―性质，状态，程度‖ purity, reality, ability, calamity11)-ment, 表示―行为，状态，过程，手段及其结果‖ treatment, movement, judgment, punishment, argument12)-ness, 表示―性质，状态，程度‖四级选词填空解题技巧发表于：2009-6-12 浏览：112 次来源：华浦华浦（Chinatop）教育集团是中国首家致力于提供升学、求职、晋升的教育培训、就业推荐的大型综合性现代教育培训集团，秉承―一站成就梦想‖的办学理念，更以其培养出众多出色的学员而成为全国著名培训机构。

Will his future brothers or sisters have a higher risk of 36 it, too?According to the largest study of siblings（兄弟姐妹）in families with autism, the answer is yes. Among 664 children who had at least one older sibling with the development disorder, the 37 risk of autism was nearly 19%, 38 higher than previous sibling-recurrence estimates that were anywhere from 3% to 10%. Kids with more than one older autistic sibling had an even higher risk of the disorder: 32%.The 39 suggest that genes play a key role in autism risk. But they also hint that other environmental factors 40 by siblings, like influences in the womb（子宫）, may be important as well.On the 41 of the findings, the researchers recommend that doctors closely 42 younger siblings of autistic children to pick up any early signs of the disorder, 43 an unusually large head or delayed language development and communication skills.

在664个家里至少有一个哥哥或姐姐患有发育障碍症的儿童中，他们患上自闭症的平均风险为将近19%，兄弟姐妹重复患病率明显高于之前的预测值——3%到10%。
如果不止一个哥哥或姐姐患有自闭症的话，这样的孩子患病的几率甚至更高，达32%。
研究结果显示基因是患有自闭症的重要因素。
但是结果也指出兄弟姐妹间共同的其他环境因素也起着很重要的作用，比如在子宫中受到的影响。
基于研究发现，研究者们建议医生严密监控自闭症儿童的弟弟妹妹，以便发现障碍症的任何早期迹象，包括头部异常偏大、语言功能和交流技能发展迟缓。
