2020年职称英语考试综合类阅读判断练习及答案(10) Disease, Diagnosis, Treatment and PreventionDisease may be defined as the abnormal state in which part or all of the body is not properly adjusted or is not capable of carrying on all its required functions. There are marked variations in the extent of the disease and in its effect on the person.In order to treat a disease, the doctor obviously must first determine the nature of the illness–this is, make a diagnosis. A diagnosis is the conclusion drawn from a number of facts put together. The doctor must know the symptoms, which are the changes body function felt by the patient and the signs(also called objective symptoms) which the doctor himself can observe. Sometimes a characteristic group of signs(or symptoms)accompanied a given disease. Such a groupis called a syndrome. Frequently certain laboratory tests are performed and the results evaluated by the physician in making his diagnosis.Although nurses do not diagnose, they play an extremely valuable role in this process by observing closely for signs, encouraging the patient to talk about himself and his symptoms, and then reporting this information to the doctor. Once the patience's disorder is known, the doctor prescribes a course of treatment, also referred to as therapy. Many measures in this course of treatment are carried out by the nurse under the physician's orders.In recent years physicians, nurses and other health workers have taken on increasing responsibilities inprevention. Throughout most of medical history, thephysician's aim has been to cure a patient of an existing disease. However, the modern concept of prevention seeks to stop disease before it actually happens - to keep people well through the promotion of health. A vast number of organizations exist for this purpose, ranging from the World Health Organization (WHO) on an international level down to local private and community health programs.

(总分7分,确保得到4-5分,掌握方法和技巧)SmokingSince 1939, numerous studies have been conducted to determine whether smoking is a ealth hazard. The trend of the evidence has been consistent and indicates that there is a serious health risk. Research teams have conducted studiesthat show beyond all reasonable doubt that tobacco smoking is associated with a shortened life expectancy1.Cigarette smoking is believed by most research workers in this field to be an importantactor in the development of cancer of the lungs andcancer of the throat and is believed to be related to cancerof some other organs of the body. Male cigarette smokers have a higher death rate from heart disease than non-smoking males. Female smokers are thought to be less affected because theydo not breathe in the smoke so deeply.Apart from statistics, it might be helpful to look atwhat tobacco does to thehuman body. Smoke is a mixture of gases, vaporized chemicals, minute particles of ash andother solids. There is also nicotine, which is powerful poison, and black tar. As smoke is breathed in, all those components from deposits on the membranes of the lungs. Onepoint of concentration is where the air tube and bronchus divides. Most lung cancer begins at this point.Filters and low tar tobacco2 are claimed to make smokingto some extent safer, but they can only slightly reduce, not eliminate the hazards.词汇:vaporize ['ve?p?ra?z] v.

Time to Stop Traveling by AirTwenty-five years ago a young British man called Mark Ellingham decided that he wanted a change of scenery. So he went to Australia, stopping off in many countries beween. Healso decided to write about the experience and produced a guide for other travelers making similar journeys.In 1970, British airports were used by 32 million people. In 2004, the figure was 216 million. In 2030, according to government forecasts, it will be around 500 million. It’s a growth driven by the emergence of low cost airlines, offering access to all parts of the world for less than £100.This has made ahuge contribution to global warming. One return flight from Britain to the US produces the same carbon dioxide (二氧化碳)as a year’s motoring (驾车). A return flight to Australia equals the emissions (排放)of three average cars for a year. And the pollution is released at a height where its effect on climate change is more than double that on the ground.Mark Ellingham built his business on helping people travel. Now he wants to help people stop –at least by air.He is calling fora £100 green tax on all flights to Europe and Africa, and £250 on flights to the rest of the world. He also wants investment to create a low-carbon economy,as well as a halt to airport expansion.Mark Ellingham’s commitmentis important because his readers aren’t just the sort of young and adventurous people who would happily jump on a plane to spend a weekend exploring a foreignculture. They are also the sort of people who say they care about the environment.It's a debate that splits people down the middle.The tourist industry has responded by offering offsetting (补偿) schemes. A small increase in the price of a ticket is used to plant trees.But critics say that it is not enough to just be carbon neutral. We should be actively cuttingback on putting greenhouse gases into the atmosphere. And for the average person,making a plane journey will be his or her largest contribution to globalwarming. It may be good to repair the damage we do. But surely it is better notto do the damage in the first place.16. Mark Ellingham spent quite a few days in China on his way to Australia 25 years ago.A.

2020年职称英语综合类阅读判断练习及答案(2)Stem Cell Therapy May Help Repair the HeartAccording to scientists in the USA,stem cell therapy may one day be able to repair the hearts of people with heart failure.Researchers at Pittsburgh University School of Medicine examined 20 patients who had severe heart failure and were going to have surgery.They injected stem cells into the parts of their hearts that were damaged.They then compared their hearts with those of people who had undergone surgery without having the stem cells injected into them(they had also suffered from severe heart failure).The patients who had the stem cells injected had hearts that were able to pump(用泵抽水)more blood than the others.According to Professor Robert Kormos,one of,the researchers,these results could revolutionize heart treatment.Although previous studies had indicated that there might be a benefit,this is the first study that has actually proved that stem cell therapy can help the failing heart work better.All the patients in this study had hearts that could not pump blood properly.The scientists measured their ejection fraction(射血分数).This is a measure of heart performance;you measure how much blood is being pumped out by the left ventricle(心室).Healthy people's ejection fraction is about 55%.These patients had ejection fraction of under 35%.They all had by-pass surgery(搭桥手术)performed on them.Some of the patients had stem cells taken from their hip bones and injected into 25-30 sites in the damaged heart muscle.Six months latertheir ejection fraction rate was 46.1% while those who just had surgery but no stem cell injections averaged 37.2%.No side effects were reported.Heart failure is a common problem all over the world.In the UK alone about 650,000 people suffer from heart failure every year.As the number of people suffering from heart failure increases in the world in general these findings are particularly significant.Current treatments relieve the symptoms.This new stemcell therapy actually repairs the damaged muscle in the heart and has the potential of curing the disease.1.The 20 patients had stem cell injections instead of surgery.A.RightB.WrongC.Not mentioned2.The experiment proved to be satisfactory.A.RightB.WrongC.Not mentioned3.The control group patients regretted not having had stem cell injections.A.RightB.WrongC.Not mentioned4.The study actually proved for the first time the benefit of stem cell therapy.A.RightB.WrongC.Not mentioned5.The ejection fraction rate of the patients with stem cell injections decreasedA.RightB.WrongC.Not mentioned6.Heart failure is more common in the UK than anywhere else in the world.A.RightB.WrongC.Not mentioned7.Stem cell therapy seems to have great prospects.A.RightB.WrongC.Not mentioned参考答案:1.B 2.A 3.C 4.A 5.B 6.C 7.A。
2020年职称英语综合类阅读判断练习及答案(1)How to Choose the Perfect StrollerFor a newborn you have to decide whether you want a pram,a car-seat frame,a travel system or a convertible stroller.As a newborn needs to lie down for the first 4-5 months of its life,a pram seems to be the perfect solution becauseit's bassinet-like sleeping space,but after the baby can sit up you’ll need a new stroller.A pram can be also quite large and expensive.A low-cost alternative can be the car seat frame that allows you to snap your infant car seat right on top.This foldable and lightweight frame can be easily stored in the truck of your car.However after the baby outgrows the infant car seat you'll have to buy a new stroller.The travel system could seem as the perfect solution for a stroller.It can be used from birth till the baby is 3 years old.This type of stroller allows you to keep the car seat on the stroller until your baby is old enough to sit up,and then remove it and seat your baby in the stroller itself.Howeverit can be that this system is quite heavy and not so easy to fold and shove in the car truck.If you want to leave the car seat out of the equation you might,consider a convertible stroller as it can be your companion from the first days of your child's life till he is in the toddler stage.The seat of a convertible stroller canbe folded back so your newborn can ride flat but as the baby grows you can fold it up and so he can also sit upright.If you are looking for a stroller for a baby that can sit upright,you might consider a lightweight stroller,a jogger or a standard stroller depending on your all day needs.Whichever type of stroller you choose you have to look up certain features like: stability,harness(five-point harnessis best),height of the handles(adjustable handle heightsmight be a plus),folding type and size(in order to be able to shove it into your truck)。
2020 年职称英语《综合类》阅读判断练习题5Dining CustomEvery land has its own dining custom,and the United States is no exception.Americans feel that the first rule of being a polite guest is to be on time.If a person is invited to dinner at 6 :30,the hostess expects him to be there at 6 30 or not more than a few minutes after.Because she usually does her own cooking,she times the meal so that the coffee and meat will be at their best at the time she asks the guest to come.If he is late,the food will not be so good,and the hostess will be disappointed.When the guest cannot come on time,he calls his host or hostess on the telephone,gives the reason,and tells at what time he thinks he can come.As guests continue to arrive,the men in the group stand when a woman enters and remain standing until she has found a chair.A man always rises when he is being introduced to a woman.A woman does not rise when she is being introduced either to a man or a woman unless the woman is much older.When the guests sit down at a dinner table,it is customary for the men to help the ladies by pushing their chairs under them.Even an American may be confused by the number ofknives,forks,and spoons beside his plate when he sits down to a formal dinner.The rule is simple,however,use them in the order in which they lie,beginning from the outside.Or watch the hostess and do what she does.The small fork on the outside on the left is for salad,which is often served with the soup.The spoon on the outside at the right is forsoup,and so on.Sometimes there is a separate little knife,called abutter spreader,on a small bread-and-butter plate at the left.As the bread is passed,each guest puts his piece on the bread-and-butter plate.1.

2020职称英语考试综合类阅读判断专项练习题(2)Students should be jealous. Not only do babies get todoze their days away,but they've also mastered the fine artof learning in their sleep.By the time babies are a year old they can recognize alot of sounds and even simple words. Marie Cheour at the University of Turku in Finland suspected that they might progress this fast because they learn language while theysleep as well as when they are awake.To test the theory,Cheour and her colleagues studied 45 newborn babies in the first few days of their lives. They exposed all the infants to an hour of Finnish vowel sounds—one that sounds like "oo",another like "ee" and a third boundary vowel peculiar to Finnish and similar languages that sounds like something in between. EEG recordings of theinfant's brains before and after the session showed that the newborns could not distinguish the sounds.Fifteen of the babies then went back with theirmothers,while the rest were split into two sleep-study groups. One group was exposed throughout their night-time sleeping hours to the same three vowels,while the others listened to other,easier-to-distinguish vowel sounds.When tested in the morning,and again in the evening,the babies who'd heard the tricky boundary vowel all night showed brainwave activity indicating that they could now recognisethis new sound. They could identify the sound even when its pitch was changed,while none of the other babies could pickup the boundary vowel at all.Cheour doesn't know how babies accomplish this night-time learning,bunt she suspects that the special ability might indicate that unlike adults,babies don’t "turn off" their cerebral cortex while they sleep. The skill probably fades in the course of the first year of life,she adds—so forget the idea that you can pick up tricky French vowels as an adult just by slipping a language tape under your pillow. But while it may not help grown-ups,Cheour is hoping to use the sleeping hours to give remedial help to babies who are genetically at risk of language disorders.练习:1. Babies can learn language even in their sleep.A. RightB. WrongC. Not mentioned2. An infant can recognize a lot of vowels by the time he or she is a year old.A. RightB. WrongC. Not mentioned3. Finnish vowels are easy to distinguish.A. RightB. WrongC. Not mentioned4. The three vowels mentioned in this article are all Finnish sounds.A. RightB. WrongC. Not mentioned5.

2020职称英语考试综合类阅读判断专项练习题(1)If leadership consists of getting things done through others,then persuasion is one of the leader's essential tools.Many executives have assumed that this tool is beyond their grasp,available only to the charismatic (有魅力的)and the eloquent.Over the past severaldecades,though,experimental psychologists have learned which methods reliably lead people to concede,comply,orchange.Their research shows that persuasion is governed by several principles that can be taught and applied.The first principle is that people are more likely to follow someone who is similar to them than someone who is not.Wise managers,then,ask peers to help make theircases.Second,people are more willing to cooperate with those who are not only like them but who like them,as well.So it's worth the time to uncover real similarities and offer genuine praise.Third,experiments confirm the intuitive truth that people tend to treat you the way you treat them.It's sound policy to do a favor before seeking one.Fourth,individuals are more likely to keep promises they make voluntarily and clearly.The message for managers here is to get commitmentsin writing.Fifth,studies show that people really do defer to (服从) experts.So before they attempt to exertinfluence,executives should take pains to establish their own expertise and not assume that it's self-evident.Finally,people want more of a commodity when it's scarce; it follows,then,that exclusive information is more persuasive than widely available data.16 Experiments have confirmed the assumption of many executives.A RightB WrongC Not mentioned17 People are more likely to cooperate with those who like them.A RightB WrongC Not mentioned18 Managers do not employ those who are quite different from them.A RightB WrongC Not mentioned19 There is no need for a manager to find out the merits of his employees.A RightB WrongC Not mentioned20 Experiments have shown that,contrary to our expectation,people tend to treat you the way you treat them.A RightB WrongC Not mentioned21 There are as many wise managers as there are stupid ones.A RightB WrongC Not mentioned22 Exclusive information is more persuasive than widely known data.A RightB WrongC Not mentioned参考答案:16.B 17.A 18.C 19.B 20.B 21.C 22.A。
2020年职称英语备考综合类阅读判断练习题题2020年职称英语备考综合类阅读判断题:California Gives Green Light to Space Solar PowerEnergy beamed down from space is one step closer to reality,now that California has given the green light to an agreement that would see the Pacific Gas and Electric Company buy 200 megawatts(兆瓦)of power beamed down from solar-power satellites beginning in 2020.But some major challenges will have to be overcome if the technology is to be used widely.A start-up company called Solaren is designing the satellites,which it says will use radio waves to beam energy down to a receiving station on Earth.The attraction of collecting solar power in space is the almost uninterrupted sunshine available in geosynchronous(与地球同步的)orbit.Earth-based solar cells,by contrast,canonly collect sunlight during daytime and when skies are clear.But space,based solar power must grapple(努力克服)with the high cost per kilogram of launching things intospace,says Richard Schwartz of Purdue University in West Lafayette,Indiana."If you're talking about it being economically viable for power of the Earth,it's a tough go,"he says.Cal Boerman,Solaren's director of energy services,saysthe company designed its satellites with a view to keeping launch costs down."We knew we had to come up with adifferent,revolutionary design,"he says.A patent the companyhas won describes ways to reduce the system'sweight,including using inflatable mirrors to focus sunlight on solar cells,so a smaller number can collect the same amount of energy.But using mirrors introduces other challenges,including keeping the solar cells from overheating,says Schwartz."You have to take care of heat dissipation(散发)because you're now concentrating a lot of energy in one place,"hesays.According to the company's patent,Solaren's solar cells will be connected to radiators to help keep them cool.Though Boerman says the company believes it can make space-based solar power work,it is not expecting to crowd out other forms of renewable ws in California and other states require increasing use of renewable energy in coming years,he points out."To meet those needs,we're going to need all types of renewable energy sources,"he says.16.Solar-power satellites will use radio waves to beam energy down from space.A.RightB.WrongC.Not mentioned17.Solaren is going to design 200 solar-power satellites.A.RightB.WrongC.Not mentioned18.Space-based solar cells could collect solar power only when skies are clear.A.RightB.WrongC.Not mentioned19.One advantage of the space-based solar power system is that it is economical.A.RightB.WrongC.Not mentioned20.Inflatable mirrors are used to reduce the weight ofthe space-based solar power system.A.RightB.WrongC.Not mentioned21.Space-based solar power will rule out other forms of renewable energy sources.A.RightB.WrongC.Not mentioned22.Many countries will grant permission for the use of space-based solar power soon.A.RightB.WrongC.Not mentioned答案解析16.A 句意:太阳能卫星将利用无线电波把能量从太空中发射回来。
关键词是beam down.依据此关键词,可在文中第一段第一句找到相关叙述:Energybeamed down from space is one step closer to reality,now that California hasgiven the green light to an agreement that would see the Pacific Gas andElectric Company buy 200 megawatts of power beamed down from solar-powersatellites beginning in 2020.(从太空中获取能量的设想距现实更近了一步,因为加州为太平洋天然气电力公司从2020年开始购买200兆瓦由太阳能卫星反射回来的能量的合约开了绿灯。
)由此可知太阳能卫星将利用无线电波把能量从太空中发射回来,故此题为"准确”的。
17.C 句意:Solaren公司计划设计200颗太阳能卫星。
关键词是Solaren和design…satellites.依据此关键词,可在文中第二段找到相关叙述:A start-upcompany called Solaren isdesigning the satellites(—家名为Solaren的新公司正在设计卫星),由此可知Solaren公司确实正在设计卫星,但文中并没提到是否会设计200颗太阳能卫星,故此题为"未提及”的。
18.B 句意:基于太空的太阳能电池只有在天气晴朗的条件下才能够收集太阳能。
关键词是collectsolar.依据此关键词,可在文中第三段的第一句找到相关叙述:The attraction of collecting solar power in space is the almostuninterrupted sunshine available in geosynchronous orbit.(在与地球同步轨道上收集太阳能几乎是不被阻断的)由此可知基于太空的太阳能电池不是只在天气晴朗的条件下才能够收集太阳能,故此题为"错误”的。
19.B 句意:基于太空的太阳能系统的一个优势是其经济性。
关键词是spaced-basedsolar power.依据此关键词,可在文中第四段第一句找到相关叙述:But space-based solar power must grapple with the high cost perkilogram of launching thingsinto space(但是基于太空的太阳能必须努力克服向太空发射器材时每公里产生的高成本),故此题为"错误”的。
20.A 句意:充气镜面被用于减轻基于太空的太阳能系统的重量。
关键词是inflatablemirrors.依据此关键词,可在文中第五段的最后一句找到相关叙述:…ways to reduce the system'sweight,including using inflatablemirrors to focus sunlight on solar cells(用于减轻系统重量的方法包括使用充气镜面使阳光集中于太阳能板),故此题为"准确”的。
