职称英语（卫生类）模拟试题（三）2
2.概括大意与完成句子：
The molecules of carbon dioxide in the Earth's atmosphere affect the heat balance of the Earth by acting as a one-way screen. Although these molecules allow radiation at visible wavelengths, where most of the energy of sunlight is concentrated, to pass through, they absorb some of the longer-wavelength infrared emissions radiated from the Earth's surface, radiation that would otherwise be transmitted back into space. For the Earth's surface, radiation that would otherwise be transmitted back into space. For the Earth to maintain a constant average temperature, such emissions from the planet must balance incoming solar radiation. If there were no carbon dioxide in the atmosphere, heat would escape from the Earth much more easily. The surface temperature would be so much lower that the oceans might be a solid mass of ice.
Today, however, the potential problem is too much carbon dioxide. The burning of fossil fuels and the clearing of the forests have increased atmospheric carbon dioxide by about 15 percent in the 1st hundred years, and we continue to add
carbon dioxide to the atmosphere. Could the increase in carbon dioxide cause a global rise in average temperature and could such a rise have serious consequences for human society? Mathematical models that allow us to calculate the rise in temperature as a function of the increase indicate that the answer is probably yes.
Under present conditions a temperature can be observed at an altitude of 5 to 6 kilometers above the Earth. Below this altitude （called the radiating level）, the temperature increases by about per kilometer approaching the Earth's surface, where the average temperature is bout. An increase in the amount of carbon dioxide means that there are more molecules of carbon dioxide to absorb infrared radiation. As the capacity of the atmosphere to absorb infrared radiation increase, the radiating level and the temperature of the surface must rise.
One mathematical model predicts that doubling the atmospheric carbon dioxide would raise the global mean surface temperature. This model assumes that the atmosphere's relative humidity remains constant and the temperature decreases with altitude at a rate of per kilometer.
The assumption of constant relative humidity is important, because water vapor in the atmosphere is another efficient
absorber of radiation at infrared wavelengths. Because warm air can hold more moisture than cool air, the relative humidity will be constant only if the amount of water vapor in the atmosphere increases as the temperature rises. Therefore, more infrared radiation would be adsorbed and reradiated back to the Earth's surface. The resultant warming at the surface could be expected to melt snow and ice, reducing the Earth's reflectivity. More solar radiation would then be absorbed, leading to a further increase in temperature.
23. Paragraph 1 ______
24. Paragraph 3 ______
25. Paragraph 4 ______
26. Paragraph 5 ______
A. The prediction of the model
B. The influence on temperature
C. The effect of carbon dioxide
D. The potential problem
E. The import of the assumption
F. The serious consequences
27. Nowadays, too much carbon dioxide ______.
28. The radiating level and the temperature of the surface must rise because of _____.
29. Only if the amount of water vapor in the atmosphere increases as the temperature rises, the atmosphere's relative humidity ______.
30. An increase in the amount of carbon dioxide means that there are more molecules of carbon dioxide ______.
A. will be constant
B. to absorb infrared radiation
C. is becoming the potential problem
D. prepare ourselves to be chemists, physicist
E. increasing capacity of the atmosphere to absorb infrared radiation
F. escape from the earth much more easily

Sleep Loss and Its Effects
Mental fatigue can be as threatening as a heart attack. Recent evidence indicates that sleepiness is a leading cause of traffic and industrial accidents. "Human error causes between 60% and 90% of all workplace accidents, depending on the type of job," observes biological psychologist David Dinges of the University of Pennsylvania. "And inadequate sleep is a major factor in human error" , other research suggests that sleep loss contributes to everything from drug abuse to poor
grades in school.
A typical adult needs about eight hours of shut-eye a night to function effectively. By that standard, million of Americans are for a long time sleep deprived, trying to get by on six hours or even less. In many household cheating on sleep has become an unconscious and harmful habit. "In its mid form, it's watching Ted Koppel and going to bed late and then getting up early to get to the gym," says Cornell's Pollak. In extreme cases people stay up most of the night, seeing how little sleep will keep them going. They try to compensate by sleeping late on weekends, but that makes up for only part of the shortfall. Over the months and years, some researchers believe, the imbalance builds up and the effects accumulate. "Most Americans no longer know what it feels like to the fully alert," contends Dr. William Dement, director of Stanford University's Sleep Center. They go through the day in a sort of twilight zone; the eyes may be wade open, but the brain is partly shut down.
Single parent Dianna Bennett, 43, works as a nurse at a correctional facility in Gardner, Mass. To be able to spend time with her three children during the day, she works the night shift, a schedule that usually allows her no more than four hours of sleep, "My kids tell me I am always tired." She says. Amy
Schwartzman, 35, a law student at Yale University, gets up at 9 a.m. and then, she attends classes and simulated court and work as a research assistant, often does not get home until 10 p.m. Nights of throwing into bed at 3 a.m. makes her feel "as if my brain isn't moving as quickly as it should be." Noting that the circles under her eyes keep getting darker, "My mother told me I look like a raccoon." Says Schwartzman.
31. Sleep loss contributes to everything EXCEPT______.
A. drug abuse
B. poor school grades
C. work effect
D. accidents
32. According to the passage, on weekends some people always ______.
A. go to bed
B. go to bed early
C. get up late
D. get up early
33. Because of sleep loss, most American ______.
A. have wide open eyes
B. are not fully alert
C. try to sleep more
D. live in the twilight zone
34. Though not stated, the author implies that ______.
A. American drug abuse is connected with loss of sheep
B. American students' poor grades result from lack of sleep
C. Adequate sleep is necessary for people's health
D. Accidents in the states could be reduced by more sleep
35. In his passage, which of the following is NOT mentioned by the author?
A. How interesting American night life is.
B. How busy some Americans are.
C. Some Americans' attitude toward sleep.
D. People should have more sleep.

Diseases of Agricultural Plants
Plants, like animals, are subject to diseases of various kinds. It has been estimated that some 30,000 different diseases attack our economic plant: forty are known to attack, and about as many attack wheat. The results of unchecked plant disease are all too obvious in countries which have marginal food supplies. The problem will soon be more widespread as the population of the world increases at its frightening rate. Even in countries which are now amply fed by their agricultural
products, there could soon be critical food shortages. It is easy to imagine the consequences of some disastrous attack on one of the major crops; the resulting famines could kill millions of people, and the resulting hardship on other millions could cause political upheavals disastrous to the order of the world.
Some plants have relative immunity to a great many diseases, while others have a susceptibility to them. The tolerance of a particular plant changes as the growing conditions change. A blight may be but a local infection easily controlled, on the other hand it can attack particular plants in a whole region or nation. An example is the blight which killed virtually every chestnut tree in North American. Another is the famous potato blight in Ireland in the last century. As a result of that, it was estimated that one million people died of starvation and related ailments.
Plant pathologists have made remarkable strides in identifying the pathogens of the various diseases. Bacteria may invade a plant through an infestation of insect parasites carrying the pathogen. A plant can also be inoculated by man. Other diseases might be caused by fungus which attacks the plant in the form of a mold or smut or rust. Frequently such a primary infection will weaken the plant so that a secondary
infection may result from its lack of tolerance. The symptoms shown may cause an error in diagnosis, so that treatment may be directed toward bacteria which could be the result of a susceptibility caused by a primary virus infection.
36. How many diseases are known to attack wheat?
A. Around 30,000.
B. Around 140.
C. Around 29,960.
D. Around 40.
37. According to this passage, which of the following would a plant disease result in if it was left unchecked?
A. A world war.
B. Border conflicts.
C. Rations of grain and meat.
D. Social upheavals.
38. What is the main idea of the second paragraph?
A. Some plants have relative immunity to a great many diseases, while others have a susceptibility to them.
B. The tolerance of a particular plant changes as the growing conditions change.
C. A blight killed virtually every chestnut tree in North American.
D. A blight may be a national infection.
39. According to the passage, some plant diseases can be prevented by ______.
A. killing parasites
B. inoculation
C. killing insects
D. improving growing conditions
40. Which of the following statements is not true?
A. Some plant diseases many be caused by bacteria.
B. Some plant diseases many be caused by pathogens.
C. Some plant diseases many be caused by fungus.
D. Symptoms are always helpful in identifying diseases.

2020年职称英语考试卫生类B级阅读判断练习及答案 （3） “We hire talent. ” Those are the words of Rod Franz， a civil service computer technology director， responding to the question of opportunities for women who are interested in pursuing careers as computer technicians. On at least one of three shifts in his operation， the male-female ratio is 50-50. That is not surprising because government and educational institutes are required by the law to make every effort to open hiring opportunities to women and minority workers. What may be even more interesting to young women is that，according to Franz， private industry is hiring women and minorities away from us. And， since private industry pays more， it succeeds. Managers in the rapidly growing computer service field are quick to agree. They strongly encourage women to train for technician jobs， and they actively recruit female technicians across the country. They believe that this career field offers a wealth of possibility for women. A recent study by the Devry Institute of Technology that involved 100 employment managers in the Chicago area showed，too， that the number of women entering the field of computer science is on the rise， and that those already in the field are moving up. A significant increase in the number of women
2020年职称英语卫生类阅读判断练习（3） Online Cancer Chat with a Safety Net Cancer Research UK has launched an online chat forum for cancer patients to swap stories and share experiences on how to cope with such a devastating disease. But Cancer Chat is a forum with a difference： it has an information safety net. This means that a Cancer Research UK team will keep a watching brief to ensure that patients are not subjected to rogue "cancer cures" or scientifically unsound information. Anyone can have access to the messages posted on Cancer Chat but if people wish to post a message they will need to register. And Rebekah Gibbs,cancer patient and star of TV's Casualty has pledged her support for the new project."I think Cancer Chat is a brilliant idea," she said."I have written a public diary about what I went through with breast cancer and I have had such a heart-warming response from other people going through the same thing. "The idea of a Cancer Chat forum means you can share information about treatment and side effects and you can really open up about your feelings online in a way that can be difficult when talking to close friends and family.And with Cancer Research UK monitoring the forum people can be reassured about the quality of information being exchanged."

2020年职称英语卫生类阅读理解专项练习（11） Calling for Safe Celebrations This Fourth of July Last Fourth of July, Pete, a 14-year-old, was enjoying the lit-up skies and loud booms from the fireworks being set off in his neighborhood. Suddenly, the evening took a terrible turn. A bottle rocket shot into his eye, immediately causing him terrible pain. His family rushed him to the emergency room for treatment. As a result of the injury, Pete developed glaucoma and cataracts. Today, Pete has permanent vision loss in his injured eye because of his bottle rocket injury. June is Fireworks Eye Safety Awareness Month, and through its EyeSmart campaign the American Academy of Ophthalmology wants to remind consumers to leave fireworks to professionals. “There is nothing worse than a Fourth of July celebration ruined by someone being hit in the eye a bottle rocket,” said Dr. John C. Hagan, clinical correspondent for the Academy and an ophthalmologist at Discover Vision Centers in Kansas City. “A safe celebration means letting trained professionals handle fireworks while you enjoy the show.” According to the U.S. Consumer Product Safety Commission, more than 9,000 fireworks-related injuries happen each year. Of these, nearly half are head-related injuries, with nearly 30 percent of these injuries to the eye. One-fourth of fireworks eye injuries result in permanent vision loss or blindness. Children are the most common victims of firework abuse, with those fifteen years old or younger accounting for 50 percent of fireworks eye injuries in the Unites States. Dr.

职称英语卫生类阅读理解原文模拟第7篇1 Dangerous Sunshine to Children Two United Nations1 agencies warned on Tuesday that children are most at risk of developing skin cancers as a result of the long-term decline in the earth's protective ozone layer. The agencies, the World Health Organization (WHO) and the UN Environmental Programme (UNEP) 2,issued the warning as they launched a global programme aimed at alerting schools to the dangers of exposure to the sun. "As ozone depletion becomes more marked, and as people around the world engage more in sun seeking behaviour, the risk of health complications from over-exposure to ultra-violet radiation is becoming a substantial public health concern," said WHO Director-genera3 Lee Jong-wook. By reducing the time children and adolescents are exposed to direct sunlight, he said: "We can substantially reduce the risk of contracting skin cancers, cataracts and other conditions4 which might only appear much later in life." In its 2002 World Health Report, the WHO said around the world an average of 66,000 people died every year

2020年职称英语卫生类阅读理解专项练习（10） Where Have Allthe Bees Gone? Scientists who study insects have a real mystery on theirhands．All across the country，honeybees are leaving their hives and neverreturning． Researchers call this phenomenon colony-collapse1 disorder．Accordingto surveys of beekeepers across the country，25 to 40 percent of the honeybeesin the United States have vanished from their hives since last fall．So far，noone can explain why． Colony collapse is a serious concern because bees playan important role in the production of about one-third of the foods we eat．Asthey feed，honeybees spread pollen from flower to flower．Without this process，aplant can’t produce seedsor fruits． Now，a group of scientists andbeekeepers have teamed up to try to figure out what’s causing the alarmingcollapse of so many colonies． By sharing their expertise in honeybee behavior，health，and nutrition，team members hope to find out what’s contributingto thedecline and to prevent bee disappearance in the future． Itcould be that disease is causing the disappearance of the bees． To explore that possibility，Jay Evans，a researcher at the United States Department ofAgriculture (USDA) Bee Research Laboratory2，examines bees taken from coloniesthat are collapsing．“We know what a healthy bee should look like on theinside，and we can look for physical signs of disease,” he says． And bees fromcollapsing colonies don’t look very healthy．“Their stomachs are
