2015年职称英语考试综合类A级补全短文模拟试题及答案

We can now watch electricity as it flows through even the tiniest circuits.By scanning the magnetic field generated as electric currents flow through objects,physicists have managed____1____.The technology will allow manufacturers to scan microchips for faults,as well as revealing microscopic defects in anything from aircraft to banknotes.

Gang Xiao and Ben Schrag at Brown University in Providence, Rhode Island,visualize the current by measuring subtle changes in the magnetic field of an object and____2____.

Their sensor is adapted1from an existing piece of technology that is used to measure large magnetic fields in computer hard drives.2”We redesigned the magnetic sensor to make it capable of measuring very weak changes in magnetic fields,”says Xiao.

The resulting device is capable of detecting a current as weak as10microamperes,even when the wire is buried deep within a chip,and it shows up features as small as40nanometers across.

At present,engineers looking for defects in a chip have to peel off the layers and examine the circuits visually;this is one of the obstacles____3____.But the new magnetic microscope is sensitive enough to look inside chips and reveal

faults such as short circuits,nicks in the wires or electro migration—where a dense area of current picks up surrounding atoms and moves them along.“It is like watching a river flow,”explains Xiao.

As well as scanning tiny circuits,the microscope can be used to reveal the internal structure of any object capable of conducting electricity.3Fpr example,it could look directly at microscopic cracks in an aeroplane’s fuselage,____4____. The technique cannot yet pick up electrical activity in the human brain because the current there is too small,but Xiao doesn’t rule it out4in the future.“I can never say never,”he says.

Although the researchers have only just made the technical details of the microscope public,it is already on sale,5from electronics company Micro Magnetics in Fall River, Massachusetts.It is currently the size of a refrigerator and takes several minutes to scan a circuit,but Xiao and Schrag are working____5____.

注释:

1.is adapted:(使)适应。作不及物动词时的用法是:“adapt to +名词性成分”,如:The young man from the countryside adapted well to life in the big city.这个农村青年很能适应大城市的生

活。易混的词:(1)adopt采取;采纳(及物动词)。adopt a positive attitude采取积极的态度。(2)adept熟练的;擅长的(形容词)。be adept in(或at),如:This boy is adept in/at figures.这个男孩擅长计算。

https://www.sodocs.net/doc/1711162181.html,puter hard drives:计算机硬盘

3.conducting electricity:导电

4.rule...out:排除……的可能性。又如:The police have ruled out murder in the case of the girl’s death.警方在姑娘死亡案中已排除他杀的可能性。

5.on sale:出售;上市。如:Will the new product be on sale next month?这种新产品下月会上市吗?

练习:

A to shrink it to the size of a desktop computer and cut the scanning

B to making chips any smaller

C to take tiny chips we require

D to picture the progress of the currents

E converting the information into a color picture showing the density

F faults in the metal strip of a forged banknote or bacteria in a water

答案与题解:

1.D manage to+v.是“设法做成”的意思。picture在此是动词,“to picture the progress of the cuixents”意为“绘出电流运行图”。

2.E by在句中引导两个在句法结构上并列的分词短语:一个是measuring subtle changes in the magnetic field of an object,另一个是converting the information into a color picture showing the density of current at each point。convert... into...的意思是“把……转变为……”。

3.B“obstacle to+名词性成分”的意思是“……的障碍”。

4.F faults in the metal strip of a forged banknote和bacteria in a water sample与前文中的microscopic cracks in an aeroplane’s fuselage在意思上是并列的关系。

5.A这部分所说的体积的减小和所需时间的缩短恰好与前半句中提到的冰箱大小的体积和所需数分钟的时间形成了对比。

Ready to Scream?

Fear can be fun.Many young people queue up to ride very fast and scary(吓人的)roller coasters,screaming but enjoying themselves.Other people like to read"goose bumps"(鸡皮疙瘩)books or watch horror movies(恐怖电影)at night,scared to death but feeling excited._____(46)

Fear is an ancient way of surviving.Being scared makes animals(including humans)flee(逃走)from danger and save

themselves.It is because of fear that we have lived through millions of years of evolution.Those who lacked a strong fear response(反应)were more likely to be killed,_____(47) What happens in the brain when something frightens you?

Nerves(神经)that begin at the eyes and ears lead to a part of the brain called the amygdala(类扁桃体).When you suddenly see a snake,for example,the amygdala makes you freeze, perspire(流汗),have a quickened heartbeat,or run very fast.

However,seeing the snake also uses another part of the brain,the cortex(皮层).It analyzes(分析)the situation,and if it finds that the snake is only made of rubber it tells your heart and the rest of your body to calm down._____(48) Back to the first question:Why do some people like to make themselves scared?

One reason is that we can play games with fear,_____(49)Kalin said:"To believe we have control over a situation gives us a feeling of power."

"Scary movies or novels are good practice to prepare young people for the real thing._____(50).

And there might be some evolutionary advantage to being able to adjust this system that is there to protect people.

A Thrills(恐惧)such as roller coaster rides also go to the

brain's pleasure centre

B Why do people like being scared?

C and find ways to reduce the scariness by looking away or thinking of something else

D leaving the more timid and careful to pass their genes(基因)onto the next generation.

E Think of the amygdala as the engine and the cortex as the brake.

F screaming saves ancient people's life.

答案:46B47D48E49C50A

From early times man has used garlic(大蒜).The Bible speaks of it.The Israelites(古以色列人)were once far from home.They cried out to Moses,their leader,for the foods they loved: leeks(韭菜),onions,and garlic.The Romans,like the Israelites,loved to eat garlic.And they hung bags of garlic around their necks._____(1)They also thought it would keep them from getting sick.

A similar idea is still held.Many people take garlic thinking it will prevent or cure disease.Most doctors say it does no such thing._____(2)Its smell may force people to stay far apart.At least then they can't pass germs on to each other. _____(3)What if you're in a play,for instance?Actors have

been known to forget their lines because they couldn't stand the garlic smell on a fellow actor's breath.Some have even made up new lines and actions that kept them far away from the one who had eaten garlic.

Through the years man has tried to cope with the smell of garlic._____(4)We now know why.It's been found that the oils of the garlic do not stick to the teeth,Garlic tongue,or gums (齿龈).They go into the lungs instead.From there they are breathed out.They pass out through the skin too.

Strange as it seems,food may have a great deal of garlic in it without smelling or tasting strong.It all depends on how it is cooked.French cooks make a good soup with whole cloves (瓣)of garlic.They use more than thirty cloves in one bowl of soup.But they take care not to crush them.And they cook them whole._____(5)And as the cloves cook they change in some strange way.The soup turns out to be delicious.It's not strong at all.

A But no medicine,mouthwash,chewing gum,or toothpaste seems to help much

B As a result,the strong oils stay in the cloves.

C They say it may help in one way,though.

D Many people eat garlic.

E But keeping your distance can be hard at times.

F They hoped it would keep away the evil eye.

答案:F C E A B

As long as we have been on earth,we have used the sea around us.We take from the ocean,and we give to it.

We take fishes from the ocean--millions of kilograms of fish,every year,to feed millions of people.(1)We take minerals from the ocean.One way to get salt is to place seawater in a shallow basin and leave it until it evaporates.(2)Much gold and silver drift dissolved in the waters of the sea,too1. But the sea does not give them up by simple evaporation.Other gifts from the sea are pearls,sponges and seaweed.Pearls become jewelry.(3)Seaweed becomes food of many kinds一even candy,and ice cream—aswell as medicine.Believe it or not, fresh water is another gift from the sea.We cannot drink ocean water.(4)But ocean water becomes fresh water when the salts are removed.In the future,we will find ourselves depending more and more on fresh water from the sea.

The sea gives us food,fertilizer,minerals,water,and other gifts.What do we give the sea?Garbage.(5)Huge as it is,the ocean cannot hold all the water that we pour into it. Dumping garbage into the ocean is killing off sea life2.Yet

as the world population grows,we may need the sea and its gifts more than ever.

We are finally learning that if we destroy our seas,we might also destroy ourselves.Hopefully,it is not too late.

注释:

Much gold and silver drift dissolved in the waters of the sea,too.还有不少金和银的漂流物溶解在海水里。

Dumping garbage into the ocean is killing off sea life.把垃圾往大海里倾倒就是在把海洋生物杀绝灭尽。

练习:

A Natural sponges become cleaning aids.

B We pollute the ocean when we use it as a garbage dump.

C The area of the sea is becoming smaller and smaller.

D Along with salt,other minerals are left after evaporation.

E We even use their bones for fertilizer.

F Some of its contents may cause illness.

答案与题解:

1.E前面二句讲了我们从大海捕捉大量的鱼供人们食用,这句接着讲“甚至连鱼的骨头也被用来做化肥”。Even这个词在这里清楚地表示了这两句话的关系。

2.D这句话的前一句讲的是我们可以通过水的蒸发从海水中得到

一种矿物质——盐,这句话则说除了盐之外,水蒸发以后还有别的矿物质留下来。

3.A前面讲到除了矿物质外,大海还给了我们珍珠、海绵和海草这三样东西。接着作者分别用一句话来说明每一样东西的昂途。先讲了珍珠,最后讲的是海草,所以这中间的一句应该是讲海绵的用途了o

4.F前一句话说了^们不能喝海水,这句话解释了为什么不能喝,很自然。

5.B前面一句话用garbage—词有力地回答了“我们给予大海什么”这个带有自责性的问题,这句话则是对这个简单回答的具体解释。

There is scarcely a place on earth which is naturally free of microorganisms(微生物).46.But on external body surfaces, on lining membranes(内膜)and inside tubes and organs that are connected with the outside—such as the mouth,throat,nose, and large intestine(肠)—both harmless and pathogenic(病原的)microbes(微生物)live in large numbers.47.If these natural defenses are sound,a person may conceal many microbes without ill effect.However,if his resistance becomes lowered, an infection can result.

Microbes are spread about through an almost infinite variety of means.48.The more crowded the conditions,the

greater the chances of epidemics(流行病)breaking out.49.

Although microbes cannot fly,the dust of the air is alive with them.In close quarters the atmosphere is further polluted by bacteria-loaded tiny drops discharged by coughing and even normal conversation.Pathogenic microbes are also spread by rats,mice,flies and mosquitoes.50.In slum areas there is often a combination of crowded conditions and poor sanitation(环境卫生).In addition,many of the inhabitants have lowered resistance because of shortage of food and other undesirable unhealthy practices.As a result,epidemics are likely to begin in these districts.

All civilized societies establish and enforce measures designed to protect the health of their populations.Most of these practices are concerned with preventing the spread of the pathogenic organisms

A The atmosphere is a carrier of microorganisms

B One exception is the interior of normal body tissue

C Microbial growth is further helped by the widespread presence of dirt and the lack of sunlight

D The body has natural defenses against these organisms

E The body has no defenses against these organisms

F The simplest way is by person-to-person contact

答案:BDFAC

2016职称英语教材-卫生类C级完形填空及参考译文1 第一篇Better Control of TB Seen If a Faster Cure Is Found The World Health Organization1 estimates that about one-third of all people are infected with bacteria that cause tuberculosis . Most times, the infection remains inactive. But each year about eight million people develop active cases of TB, usually in their lungs. Two million people die of it. The disease has increased with the spread of AIDS and drug-resistant forms of tuberculosis. Current treatments take at least six months. People have to take a combination of several antibiotic drugs daily. But many people stop as soon as they feel better. Doing that can lead to an infection that resists treatment. Public health experts agree that a faster-acting cure for tuberculosis would be more effective. Now a study estimates just how effective it might be. A professor of international health at Harvard University2 led the study. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean fewer infectious patients who can pass on their infection to others. The researchers developed a mathematical model to examine the effects of a two-month treatment plan. They tested the model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. And it might prevent about twenty-five percent of TB deaths. The model shows that these reductions would take place between two thousand twelve and two thousand thirty. That is, if a faster cure is developed and in wide use by two thousand twelve. The World Health Organization reductions the DOTS3 program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make sure they continue treatment. Earlier this year, an international partnership of organizations announced a plan to expand the DOTS program. The ten-year plan also aims to finance research into new TB drugs. The four most common drugs used now are more than forty years old. The Global Alliance for TB Drug Development4 says its long-term goal is a treatment that could work in as few as ten doses. 1.找到速效治疗剂可以更好控制结核病 世界卫生组织估计全球有大约三分之一的人感染了导致结核病的病菌。大多数时候,这种感染是不活跃的。但是每年大约有八百万结核病病例,通常是在肺部。两百万人因此丧命。结核病发病率由于艾滋病的传播和抗药型结核病的出现而增加。目前的治疗至少需要六个月。患病者不得不每日服用多种抗生素药品。许多人在稍感舒适后就停止使用药品,这么做可能导致抗药性感染。公共卫生专家一致认为针对结核病的速效治疗剂将会更加有效果。现在有一项研究评估这种速效治疗剂究竟效力有多大。这项研究由美国哈佛大学国际卫生方面的教授率领。Joshua Salomon说,疗程较短的治疗计划可能不仅仅意味着更多病人被治好,也意味着将感染传给别人的病人会更少。 研究者们设计了一个数学模型来检测两个月治疗计划的效果。他们以东南亚目前的结核病情况来检验这个模型。科学家们发现两个月的治疗可以防止大约20%的新病例,也可能防止大约5%因结核病引起的死亡。这个模型表明,如果速效治疗剂可以在2012年前研发出来并大规模使用的话,减少结核病例在2012年到2030年间就可以实现。 世界卫生组织在1990年制定了DOTS计划,DOTS意指短期直接观察治疗。卫生工作者监督结核病人每天服药,以确信他们继续治疗。今年年初,一个国际组织同盟宣布了一项扩大DOTS的计划。这个十年计划也旨在资助新结核药品的研究。现在四种最常用的药品也有四十多年的历史了。全球结核病药物开发联盟宣称它的长期目标是找到一种治疗方法,可以通过十次剂量就效果。

The First Four Minutes最初四分钟 When do people decide whether or not they want to become friends?人们什么时候决定他们是否愿意成为朋友?During their first four minutes together, according to a book by Dr. Leonard Zunin. In his book, “Contact:The first four minutes" he offers this advice to anyone interested in starting new friendships:“Every time you meet someone in a social situation, give him your undivided attention for four minutes. (1) A lot of people's whole lives would change if they did just that. ”按列奥纳多?祖尼博士的书中所说是在他们相处的最初四分钟。在他的书《接触:最初四分钟》里,他向所有对开始新的友谊感兴趣的人们提出了这样的建议:“每次你在社交场合遇到什么人时,全神贯注地注意他四分钟。如果这样做了的话,他们的生活就会完全不同。”; You may have noticed that the average person does not give his undivided attention to someone he has just met. 你可能已经注意到了,一般人都不会全神贯注地注意一个他刚认识的人。(2) He keeps looking over the other person's shoulder, as if hoping to find someone more.他不停地往其他人身后看,好像要在屋里其他地方找到更趣的人似的。If anyone has ever done this to you, you probably did not like him very much.如果有人对你这样,你大概不会很喜欢他。

When something creates a sound wave in a room or anauditorium, listeners hear the sound wave directly from the source. They alsohear the reflections as the sound bounces off thewalls. floor, and ceiling. These are called the reflected wave or reverberant(反射)sound, which can be heard evenafter the sound is no longer coming from the source. The reverberation time of an auditorium isdetermined by the volume or interior size of the auditorium. It is alsodetermined by how well or how poorly the walls, ceiling, floor, and contents ofthe room (including the people) absorb sound. There is no ideal reverberation time,because each use of an auditorium calls for different reverberation. Speechneeds to be understood clearly; therefore rooms used for talking must have ashort reverberation time. The full-sound performance of music such ad Wagneroperas or Mahler symphonies should have a long reverberation time. The light,rapid musical passages of Bach or Mozart need a reverberation time somewherebetween. Acoustic problems often are caused by poorauditorium design. Smooth, curved reflecting surfaces create large reflections.Parallel (平行的)wallsreflect sound back and forth, creating a rapid, repetitive pulsing https://www.sodocs.net/doc/1711162181.html,rge pillars (柱)and comerscan cause acoustic shadows as the sound waves try to pass around the object.Some of these

Similar to your bedside alarm clock,your internal clock2 runs on a 24-hour cycle. This cycle,called a circadian rhythm,helps control when you wake,when you eat and when you sleep. Somewhere around puberty,something happens in the timing of the biological clock. The clock pushes forward,so adolescents and teenagers are unable to fall asleep as early as they used to. When your mother tells you it's time for bed,your body may be pushing you to stay up3 for several hours more. And the light coming from your computer screen or TV could be pushing you to stay up even later. This shift4 is natural for teenagers. But staying up very late and sleeping late can get your body's clock out of sync with the cycle of light and dark5. It can also make it hard to get out of bed in the morning and may bring other problems,too. Teenagers are put in a kind of a gray cloud6when they don't get enough sleep,says Mary Carskadon,a sleep researcher at Brown University in Providence,RI7 .It affects their mood and their ability to think and learn. But just like your alarm clock,your internal clock can be reset. In fact,it automatically resets itself every day. How? By using the light it gets through your eyes. Scientists have known for a long time that the light of day and the dark of night play important roles in setting our internal clocks. For years,researchers thought that the signals that synchronize the body's clock8were handled through the same pathways that we use to see. But recent discoveries show that the human eye has two separate light-sensing

2020职称英语补全短文练习题(1)

2020职称英语补全短文练习题(1) The Invader of AIDS The invader is small, even in the microscopic world of bacteria and viruses. It is alive only in the strictest sense of the world. It had no intelligence, no means of mobility, no methods of defense in the outside world. It is fragile, easily killed by common household bleach(漂白剂)and even short periods outside the body. 1 . It is the AIDS virus, and it is a killer. AIDS is a disease, caused by a virus that breaks down part of the body’s immune system, leaving a person defenseless against a variety of unusual life-threatening illnesses.2 . The body’s immune system normally provides us the weapons we need to win constant battles with invading viruses, bacteria and other invading organisms. His defense system is powerful but not perfect. 3 . We do not even know that anything is happening. But the AIDS virus acts differently from other invaders. It attacks the very cells that normally protect us. 4 . It turns our own white blood cells into mini-factories or making more viruses. Each time a cell is taken over, it fills up with thousands of new viruses, dies and releases those viruses, with attack more white blood cells. After enough attacks, our defense system is weakened and certain infections and conditions that we normally fight off with no problem take advantage of his weakness.

Buildings would rotate so they could follow the sun to take maximum advantage of its light and heat Walls would "radiate light" and "change color with the push of a button." Food would be replaced by pills. School would be taught "by electrical impulse while we sleep." Cars would have radar. Does this sound like the year 2000? Actually, the article was written in 1958 and the question was, "what will life be like in 1978?" The future is much too important to simply guess about, the way the high school students did, so experts are regularly asked to predict accurately. By carefully studying the present, skilled businessmen, scientists, and politicians are supposedly able to figure out in advance what will happen. But can they? One expert on cities wrote: Cities of the future would not be crowded, but would have space for farms and fields. People would travel to work in "airbuses", large all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents "almost unheard of". Does that sound familiar? If the expert had been accurate it would, because he was writing in 1957. His subject was "The city of 1982". If the professionals sometimes sound like high-school students, it's probably because future study is still a new field. But economic forecasting, or predicting what the economy will do, has been around for a long time. It should be accurate, and generally it is. But there have been some big market in the field, too. In early 1929, most forecasters saw an excellent future for the stock market. In October of that year, the stock market had its worst losses ever, ruining thousands of investors who had put their faith in financial foreseers. One forecaster knew that predictions about the future would always be subject to significant error. In 1957, H.J.Rand of the Rad corporation was asked about the year 2000, "Only one thing is certain," he answered. "Children born today will have reached the age of 43." 1. The high-school students' answers to "What would life be like in 1978?" sound A) accurate. B) imaginative. C) correct. D) foolish. 2. According to the writer, forecasting is fairly accurate in A) politics. B) science. C) sociology. D) economy. 3. Which of the following statements is not compatible with the writer's comment on future study?
