2020年职称英语考试卫生类C级阅读复习(3)Medical JournalsMedical journals are publications that report medical information to physicians and other health professionals.In the past, these journals were available only in print. With the development of electronic publishing. many medical journals now have Web sites on the Internet, and somejournals publish only online. A few medical journals, likethe Journal of the American Medical Association, are considered general medical journals because they cover many fields of medicine. Most medical journals are specialty journals that focus on a particular area of medicine.Medical journals publish many types of articles. Research articles report the results of research studies on a range of topics varying from the basic mechanisms of diseases toclinical trials that compare outcomes of different treatments. Review articles summarize and analyze the informationavailable on a specific topic based on a careful search ofthe medical literature. Because the results of individual research studies can be affected by many factors, combining results from different studies on the same topic can behelpful in reaching conclusions about the scientific evidence for preventing, diagnosing or treating a particular disease. Case conferences and case reports may be published in medical journals to educate physicians about particular illnesses and how to treat them. Editorials in medical journals are short essays that express the views of the authors, often regarding a research or review article published in the same issue.Editorials provide perspective on how the current articlefits with other information on the same topic. Letters to the editor provide a way for readers of the medical journal to express comments, questions or criticisms about articles published in that journal.注释:1.

2020年职称英语卫生类C级概括大意历年真题及解析2020年真题Ebola Outbreak1 You are likely aware that several countries in West Africa are batting an Ebola Outbreak.Ebola is a dangerous and often lethal viral infection. Scientists believe that humans contacted the virus by eating the meat of rare animals. It is now believed that bats are the primary carriers of the virus.2 To date, there are only three major countries in West Africa experiencing a major outbreak:Sierra Leone, Liberia and Guinea. However, other countries such as Nigeria have reported confirmed cases of Ebola within their borders.3 Unless you recently visited one of the three affected West countries, your risk of contacting the virus isvirtually zero. Unlike other recent airborne virus outbreaks like SARS, the Ebola virus can only be spread through direct contact with an infected person. Spbcifically, Ebola is spread through contact with body fluids. Though, the virus is transmittable, only an infected person exhibiting symptoms is communicable.4 The signs and symptoms of Ebola are non-specific and patients typically exhibit them after a week of contacting the virus. Symptoms may appear as early as two days or aslate as three weeks after initial infection. Symptoms includedisgust, weakness and stomach pain. More uncommon symptoms include chest pain, bleeding and sore throat.5 Ebola is devastating because of its ability to attack and replicate in every organ of the body.This causes an over-stimulation of the body's inflammatory response, causing the flu-like symptoms. The virus also causes bleeding and impairs the body's normal clotting mechanism(凝血机制), making bleeding even more severe. Loss of blood volume and decreased organ perfusion (器官灌注), ultimately lead to organ failure and death.6 The current outbreak is the deadliest viral outbreak in over 35 years. While diseases such as the malaria (疟疾) are far more communicable, Ebola is one of the world's most fatal viral infections. Ebola's fatality rate exceeds that of SARS.23. Paragraph 2 __________24. Paragraph 3 __________25. Paragraph 4 __________26. Paragraph 5 __________A. Am I at risk of contacting the virus?B. Is the current outbreak the deadlines?C. How do I know ifI have contacted the virus?D. What areas are currently affected?E. What exactly does Ebola do to the body?F. What caused the Ebola outbreak?27. The initial Ebola outbreak was found in28. The difference between SARS and Ebola viruses liesin__________.29. The symptoms of the patients after being infected may first appear __________.30. The Ebola virus transmits by contact with __________.A. infected body fluidsB. against the outbreak severityC. the mode of transmissionD. the initial days of being infectedE. three countries in West AfricaF. within a wide range of days2020年真题Eye Problems1 Our eyes are under a great deal of strain these days as computer work, television viewing, night driving, and even sunshine are making exceptional demands. Sunlight, especially in the summer,is now regarded as one cause of cataracts ( 白内障).2 The thinning of the ozone (臭氧) layer means moreshort-wave ultraviolet (UV) rays (紫外线)are reaching the earth, and these are the biggest risk factor for clouding the lens of the eye.Ultraviolet rays increase the risk of changes to the cornea (角膜) causing clouded vision andeventually cataracts. The rays can be shielded only by anti-UV lenses. However, our eyes are not sufficiently protected by fashion sunglasses.3 “Poor night vision and eye fatigue are noticeably more common, and there has been a big increase in minor eye complaints in the over-40s," says Dr. M/re/lle Bonnet, who took part in recent research. She says that the six muscles controlling each eye move more than100,000 times a day and that everyone should learn to exercise their eye muscles and allow them to rest.4 It was traditionally thought that near-or far-sightedness were inherited from our parents and could not be influenced by environmental factors, but new research is challenging this assumption.5 Recent studies suggest that up to 80 percent of schoolchildren in the United States and western Europe are nearsighted. Years of focusing on close, two-dimensional work causes most children to become at least slightly nearsighted by the age of 10, say the researchers.6 Problems with night vision, which affect around 25 percent of people, are also on the increase because of computer use. Using computer screens means the eye must operate in electromagnetic fields (电磁场) that make it work harder. It is estimated that 25 to 30 percent of people have eye conditions, such as difficulty with night vision, which results from staring at a screen.23. Paragraph 2 __________24. Paragraph 3 __________25. Paragraph 5 __________26. Paragraph 6 __________A. The development of poor night visionB. The greatest threat to the eyesC. The function of sunglassesD. The reason for children's nearsightednessE. The effects of computer on the eyesF. The ways to reduce eve comolaints27. Sunlight in the summer is believed to be one cause of__________.28. We can wear anti-UV glasses to protect ___________.29. We used to believe that near-or far-sightedness were inherited from __________.30. Over 25% of people are estimated to have difficulty with night vision due to __________.A. our parentsB. clouded visionC. eye musclesD. our eyesE. computer useF. eye move2020年真题Traffic Jams--No End in Sight1 Traffic congestion (拥堵) affects people throughout the world. Traffic jams cause smog in dozens of cities acrossboth the developed and developing world. In the U. S., commuters (通勤人员) spend an average of a full working week each year sitting in traffic jams, according to the Texas Transportation Institute. While alternative ways of getting around are available,most people still choose their cars because they are looking for convenience, comfort and privacy.2 The most promising technique for reducing city traffic is called congestion pricing, whereby cities charge a toll to enter certain parts of town at certain times of day. In theory, if the toll is high enough, some drivers will cancel their trips or go by bus or train. And in practice it seemsto work: Singapore, London and Stockholm have reducedtraffic and pollution in city centres thanks to congestion pricing.3 Another way to reduce rush-hour traffic is for employers to implement flextime, which lets employees travel to and from work at off-peak traffic times to avoid the rush hour. Those who have to travel during busy times can do their part by sharing cars. Employers can also allow more staffto telecommute (work from home) so as to keep more cars offthe road altogether.4 Some urban planners still believe that the best way to ease traffic congestion is to build more roads, especially roads that can take drivers around or over crowded "citystreets. But such techniques do not really keep cars offthe road; they only accommodate more of them.Other, more forward-thinking, planners know that more and more drivers and cars are taking to the roads every day, and they are unwilling to encourage more private automobiles when public transport is so much better both for people and the environment. For this reason, the American government has decided to spend some $7 billion on helping to increase capacity on public-transport systems and upgrade them with more efficient technologies. But environmentalists complain that such funding is tiny compared with the$50 billion being spent on roads and bridges.23. Paragraph 1 __________24. Paragraph 2__________25. Paragraph 3 ___________26. Paragraph 4 __________A. Paying to get inB. Changing work practiceC. Not doing enoughD. A solution which is no solutionE. Closing city centres to trafficF. A global problem27. Most American drivers think it convenient to__________.28. If charged high enough, some drivers may __________to enter certain parts of town.29. Building more roads is not an effective way to__________.30. The U. S. government has planned to__________updating public-transport systems.A. reduce traffic jamsB. drive aroundC. go by busD. spend more moneyE. travel regularlyF. encourage more private cars答案与解析2020年真题23.D。

Privacy Worry May Keep HIV Patients from TherapyPatients infected with HIV are often concerned about the confidentiality of their HIV-positive status. In fact, some patients are so worried that they will actually give up treatmentto prevent the release of this information, according to a report published in the Augustissue of AIDS Care.Dr. Kathryn Whetten-Goldstein and colleagues from Duke University, Durham, NorthCarolina, studied theconfidentiality issues of 15 HIV-infected patients from rural NorthCarolina locations. They were divided into groups designed to explore their attitudestoward, and experiences with, breaches in confidentiality."The fear of a breach in confidentiality is definitely affecting the care that HIV-infectedpatients receive," Whetten-Goldstein said. "Most studied patients had experienced or knewsomeone who had experienced a breach in confidentiality.""Two types of breaches occurred, " Whetten-Goldstein noted. "The first was a moreobvious type of breach. One example was a nurse whotold her child that her patient wasHIV-positive out of concern that her child would play with the patient's child.""The other type of breach was more subtle, one that providers might not consider breaches," Whetten-Goldsteinexplained. "This type of breach involves providers talking about apatient's HIV status without the patient's knowledge of the interaction.""The law allows the sharing of information between providers within the same institution,but patient's consent must be obtained before providers at different institutions can shareinformation,"she pointed out."Patients in the study wanted providers to tell them when they are going to shareinformation with other providers and why it is being done," Whetten-Goldstein said. "They alsofelt that providers should be punished when a breach occurs.""However, because patients are often reluctant to seek legal action which may further expose their status, they felt that the system should regulate itself," she added. All patients in the study refuse to receive any treatment because of the possibility to expose their HIV status.A: RightB: WrongC: Not mentioned答案:B解析:题干:研究中所有的病人都拒绝接受任何治疗,因为这可能会暴露自己携带HIV病毒的状况。

2020年职称英语卫生类C级模拟试题及答案(6)第3篇:Some things we know about languageMany things about language are a mystery, and many will always remain SO.But somethings we do know.First,we know that all human beings have a language of some sort.There is no race of men anywhere on earth so backward that it has no language,no set of speech sounds by which the people communicate with one mother.Furthermore,in historical times,there has never been a race of men withouta language.Second,there is no such thing as a primitive language.There are many people whosecultures are undeveloped,who are,as we say,uncivilized, but the languages they speak are not primitive.In all known1anguages we can see complexities that must have been tens of thousands of years in developing.This has not always been well understood;indeed, thedirect contrary has often been stated.Popular ideas of the1anguage of the American Indians will illustrate.Many people have supposed that the Indians communicated in a veryprimitive system of noises.Study has proved this to be nonsense.There are,or were,hundreds of American Indian languages,and a11 of them turn out to be very complicatedand very old. They are certainly different from the languagesthat most of us are familiar with,but they are no more primitive five than English and Greek.A third thing we know about language is that alllanguages are perfectly adequate.That is, each one is a perfect means of expressing the culture of the people who speak the language.Finally, we know that language changes.It is natural and normal for language to change;the only languages which do not change are the dead ones.This is easy to understand if we look backward in time.Change goes on in all aspects of language.Grammatical features change as do speech sounds,and changes invocabulary are sometimes very extensive and may occur very rapidly.Vocabulary is the least stable part of any language.词汇:race/n.种族primitive/adj.原始的uncivilized/adj.不开化的,落后的complexity/n.复杂性,复杂现象nonsense/n.胡说,没有根据的话extensive/adj.广泛的vocabulary/n.词汇练习:1.

U.S. to Start $3.2 Billion Chiltd Health Study in January
A study that will cost $3.2 billion and last more than two decades to track the health of100,000 U.S. children from before birth to age 21 will be launched in January, U. S. health officials said on Friday.
Officials from the U. S. government's National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that affect later development, with the goal of learning new ways to treat or prevent illness.
The study will examine hereditary and environmental factors such as exposure to certain chemicals that affect health.
Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to construct their residences, the NIH said.
Officials said more than $200 million has been spent already and the study is projected to cost $3.2 billion.
"We anticipate that in the long term, what we learn from the study will result in a significant savings in the
nation's health care costs," Dr. Duane Alexander, who heads
the NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters.
The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up pregnant women whose babies will then be followed to age 21.
Some of the early findings will be about factors behind pre-term birth, which has become more common in recent years, according to Dr. Peter Scheidt of the NIH, who heads the study.
The people taking part will be from rural, urban and suburban areas, from all income and educational levels and from all racial groups, the NIH said.
