3、CancerCancer is a group of many related diseases that begin in cells, the body's basic building blocks. The body is made up of many types of cells. Normally cells grow and divide to produce more cells as they are needed to keep the body healthy. Sometimes, this orderly process goes wrong. New cells form when the body does not need them, and old cells do not die when they should. The extra cells form a mass of tissue called a growth or tumor. Benign (良性的) tumors are not cancer. They can often be removed and, in most cases, they do not come back. Malignant (恶性的) tumors are cancer. Cells in malignant tumors are abnormal and divide without control or order.Scientists have learned that cancer is caused by changes in genes that normally control the growth and death of cells. Certain lifestyle and environmental factors can change some normal genes into genes that allow the growth of cancer. Many genechanges that lead to cancer are the result of tobacco use, diet, exposure to ultraviolet radiation from the sun, or exposure to carcinogens (致癌物) in the workplace or in the environment. Some gene alterations are inherited.Cancer treatment can include surgery, radiation therapy, chemotherapy (化疗), hormone therapy, and biological therapy. The doctor may use one method or a combination of methods, depending on the type and location of the cancer, whether the disease has spread, the patient's age and general health, and other factors. Because treatment for cancer can also damage healthy cells and tissues, it often causes side effects. Patients and doctors generally discuss the treatment options, weighing the likely benefits of killing cancer cells and the risks of possible side effects.Having cancer does not always mean having pain. Whether a patient has pain may depend on the type of cancer, the extent of the disease, and the patient's tolerance for pain. Most pain occurs when the cancer grows and presses against bones, organs, or nerves. Pain may also be a side effect of treatment. However, pain can generally be relieved or reduced with prescription medicines or over-the-counter drugs recommended by the doctor.Paragraph 1____.【单选题】A.Does cancer always cause painB.Can cancer be preventedC.What is cancerD.How common is cancerE.What causes cancerF.How is cancer treated正确答案:C答案解析:第一段没有主题句,该段主要介绍了癌症是由控制细胞生长增殖机制失常而引起的疾病,本段对癌症进行了简单的界定。

职称英语考试《卫生类》模拟试题及答案0510-331、Gun Rights in the USImmediately after the shooting at Virginia Tech University, Americans gathered to mourn the dead. The president and the state governor both hurried there to share the grief. But the majority of Americans still cling to their right to own weapons. Strictly speaking, the US is not the only country where gun violence has destroyed lives, families and communities in everyday circumstance. But the US is one of the few countries that seems unwilling and politically incapable of doing anything serious to stop it.In countries like Britain and Canada. The government adopted stricter gun control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby and the electoral system.The powerful National Rifle Association, the major supporter of gun rights in the US, is too strong for any party to take on. Most Republicans oppose gun controls anyway. Over the years, theDemocrats have found that they can either campaign for gun control or win power, not both; they prefer power. According to the US Bureau of Justice Statistics, firearm incidents accounted for nine percent of the 4.7 million violent crimes in 2005. So, although opinion polls show most Americans want stricter gun laws, many don't want to give up their arms they keep to protect themselves.Dave Hancock, a Virginia gun lover, is one example. In an interview he said. "If one professor in Virginia incident had been carrying a legal weapon they might have been able to____ all this. " In his opinion, the massacre is an argument for more people to carry, weapons, not fewer.But at the root of Americans' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government , commented UK's Guardian newspaper.One Virginia resident, who had a permit to carry; a concealed firearm, told the Guardian thin itwas every American's responsibility to have a gun."Each person," he said, "should not rely solely on the government for protection. "【单选题】A.controlB.stopC.handleD.treat正确答案:B答案解析:本句的if条件句,用了虚拟语气,表示一种没有成为现实的假设。

2016年职称英语考试《卫生类》精选练习题4

2016年职称英语考试《卫生类》精选练习题4

阅读理解Physical ExerciseDeclaring that physical exercise is one of the most powerful medicines to help improve our quality of life is not an exaggeration.The World Health Organization expressed the same view in its 2002 World Heath Report.emphasizing that the damage produced by lack of physical activity was equal to the strong probability of serious illness such as heart disease and even some kinds of cancer.Those who have embraced an active lifestyle for years are familiar with the sort of physical and psychological benefits that come from exercise. Nevertheless a lot of people would never think of physical activity as a way of feeling better,simply because they don’think they are in need of it.Or because they are lazy or maintain that they haven’t got enough time.There are many positive effects that result from physical exercise and they are not only concerned with the physical aspects but also psychological and social ones.Beginning with the physical benefits,physical activity improves the life of the heart,bums off fat.lowers high blood pressure, makes tissues more resistant,and increases muscle flexibility and joint mobility.On a psychological level,physical activity helps reduce anxiety and stress by causing tension to disappear and by encouraging US to have a better sense of ourselves through listening to our bodies during movement.Lastly,seeing ourselves in better health is advantageous socially .The sense of satisfaction thus obtained will result in an increase of self—respect and self-confidence in terms of our ability to interact with others.The benefits linked to exercise have also not gone unnoticed in the business world,with more and more companies setting up gyms on-site.Employees’improved health translates into better performance and reduced costs as well as an increase in people’s satisfaction in the work place.Physical activity is recommended for all age groups,including children.It is an important growth factor in a child’s education.And for the elderly ? There is no doubt that regular physical activity allows greate. efficiency in daily life as well as creating more basic independence day by day,including the possibility of keeping in touch with others and not feeling isolated.根据以上内容,回答31-45题。

approximatelyA.appropriatelyB.apparentlyC.exactlyD.or so正确答案:D5.The tramp carried all his belongings in a pack on his backA.truck driverB.vagabondC.murdererD.old man正确答案:BEating Potatoes Gives Your Immune System a BoostEating potatoes is not only good for bowel health,but also for the whole immune system,especially when they come in the form of a potato salad or eaten cold.In a study on an animal model,researchers in Spain found that pigs fed large quantities of raw potato starch(RPS)1not only had a healthier bowel,but also decreased levels of white blood cells,such as leucocytes and lymphocytes in their blood.White blood cells are produced as a result of inflammation or disease,generally when the body is challenged.The general down-regulation of leucocytes observed by the Spanish researchers suggests an overall beneficial effect,a generally more healthy body.2The reduction in leucocyte levels was about15percent.Lower lymphocyte levels are also indicative of reduced levels of inflammation,but the observed reduction in both lymphocyte density and lymphocyte apoptosis is surprising.In what was the longest study of its kind,pigs were fed RPS over14weeks to find out the effect of starch on bowel health.“The use of raw potato starch in this experiment is designed to simulate the effects of a diet high in resistantstarch”,said study leader Jose Francisco Perez at the Universitat Autonoma de Barcelona,3Spain.Humans do not eat raw potatoes,but they do eat a lot of foods that contain resistant starch,such as cold boiled potatoes,legumes,grains,green bananas, pasta and cereals.About10percent of the starch eaten by human is resistant starch -starch that is not digested in the small intestine and so is shunted into the large intestine where it ferments.Starch consumption is thought to reduce the risk of large bowel cancer and may also have an effect on irritable bowel syndrome(IBS).4Immunology expert Lena Ohman’s team previously found that the overall lymphocyte levels do not vary for IBS patients,but that lymphocytes are transferred from the peripheral blood to the gut,which support the hypothesis of IBS being at least partially an inflammatory disorder.She says the decrease in lymphocytes observed by the Spanish is therefore interesting,and a diet of resistant starch may be worth trying in IBS patients.Ohman is currently at the Department of Internal Medicine, Goteborg University,Sweden.5The study is published in the journal Chemistry and Industry,the magazine of the SCI.631.What a form of potato is the most nutrient to the human body?A.Potato soup.B.Potato cake.C.Potato salad.D.Hot boiled potato.正确答案:C32.What does the reduction in leucocyte levels in the body mean?A.It may mean the reduced levels of inflammation.B.It may mean somewhere in the body is inflamed.C.It means that the body is challenged.D.It means that the body cannot produce leucocytes any more.正确答案:A33.For what a purpose did the researchers use raw potato starch in their experiment?A.They wanted to observe how the leucocyte levels reduced in the experimental pigs?B.They wanted to simulate the effects of a diet high in resistant starch.C.They wanted to see how much potato an experimental pig ate every day.D.They wanted to see how much body weight each experimental pig gained in the end.正确答案:B34.All of the following foods are rich in resistant starch EXCEPT__________.A.PastaB.GrainsC.LegumesD.Vegetables正确答案:D35.What a kind of starch is resistant starch after all?A.It may cause irritable bowel syndrome.B.It may bring about at least partially inflammatory disorder.C.It may raise leucocyte and lymphocyte levels in the body.D.It cannot be digested in the small intestine and ferments in the large intestine.正确答案:DStop Snoring--Save Your RelationshipDo you find your day ruined because of your partner sleeping and snoring loudly beside you?Although you are trying to be the nicest partner that you are supposed to be,you can't help but be stressed at this situation.Obviously,you cannot get enough sleep because of the loud noise coming out of your partner's nose or is that his or her mouth?Every night,you just want to yell at him and say,"Stop snoring!"Yes,it can go from a simple annoyance to an actual break up.For one,you two will continuously argue about the fact the one with the snoring problem simple dismisses it as a normal sleeping disorder.But of course,since you are the one at the sour end receiving all these kinds of noises while you are trying to sleep, you can't help but argue incessantly which in some cases will eventually lead to a recurring misunderstanding and then to a final break-up.For the ones who cannot sleep because of the snoring issue,they will notice that they are often in a bad mood which affects their gusto for sex and their life in general as a couple.If you are the one snoring,then you better search for a snoring cure or means to at least lessen the noise.It is understandable that your partner can now easily become aggravated given the fact the he or she cannot get the needed sleep especially if he or she still works during the day.Snoring has significant effects on your partner.Seeking medical advice is the best solution to this problem.It is a problem whether you accept it or not.And treatment is necessary in order for you to live life and sleep normally once again and stop snoring completely.It can be a result of a bigger physical problem so you better have it looked at before dismissing it as normal.Snoring can be corrected.It should not be a lifetime condition.It can be indicative of a disease which is far more serious that you initially thought.To stop snoring,have it checked and better consult a specialist to seek proper advice on diet,snoring cure,exercise regimen or any other treatments available.16.Sometimes you cannot get enough sleep because your partner snores.A.RightB.WrongC.Not mentioned17.Snoring may finally lead to the break up of the relationship.A.RightB.WrongC.Not mentioned18.As a couple,bad sleep caused by snoring may affect their general life,but will not reduce their interests for sex.A.RightB.WrongC.Not mentioned19.If

pig populations,but certain outbreaks occur on cold season,on winter and fall,just like how ordinary flu affects human beings.2Swine flu infects human beings and over two thousand cases of affected individuals confirm that swine flu is indeed something to be taken seriously. Normally,swine flu is not transmitted to humans.But within the bodies of swine, a process called the antigenic shift make swine flu a very contagious disease not only among pigs but also among us,people.Pigs are not only carriers of ordinaryswine flu viruses,they are also carriers of other animals’viruses-such as of birds and of human beings.This ordinary human flu can turn into a human-infecting swine flu once combined with other flu viruses.As different types of viruses are being carried by pigs,viruses may reassort and swap genes with each other to develop a new strain of flu virus.This evolved virus is now being responsible for the present swine flu epidemic.3Swine flue affects people like the ordinary flu such as sore throat,cough, nasal congestion,fever,headache,chills body aches,and fatigue.Some patients also reported diarrhea and vomiting as symptoms.Although swine flu is curable with some drugs,about150deaths that were caused by swine flu have been reported.4To prevent swine flu,people should take personal health precautions such as cleaning one’s hands and other hygienic practices.Since swine flu appears to be just like an ordinary flu,it would be wise for people,whether they think they have swine flu or not,to cough and sneeze on tissue papers and properly dispose them on trash cans.People should also refrain from touching their lips,eyes and nose unless their hands are really clean.Swine flu is not transmitted by eating pork since swine flue viruses are killed in meat-cooking temperature.However,one should still be careful when eating or drinking.It would be safe to make sure that one’s food is safe from germs.23Paragraph124Paragraph225Paragraph326Paragraph4A.The definition of swine fluB.The disease is incurableC.The way the disease is transmitted to peopleD.The disease has caused much deathsE.Things we should do protect ourselvesF.The symptoms and influence of swine flu27Pigs not only carry swine flu viruses,they also28Viruses inside pigs may exchange genes to29To prevent swine flu,people should30Cooked pork willA.form hygienic and healthy habitsB.develop a new strain of flu virusC.still help transmit swine flu virusesD.carry other animals’virusesE.become an antiviral medicineF.not help transmit swine flu viruses正确答案:ACFE DBAFThe Magic of SoundMusic is one of the most beautiful forms of artistic expressions ever invented. In movies and plays,music has an added function1:it not only moves people but also can shock people.Is it true that an ordinary musical instrument can be so powerful?Our eardrums can withstand sound within20to80decibels.Once sound exceeds this limit2,even beautiful music will become car-splitting noise3and harm health.A strong blast of high sound can twist and break a solid iron sheet.1The noise from a plane’s engine is over140decibels.However,the sound of a flute is at most a few decibels.2It has been proven that people who have worked in an environment with a high sound intensity for a long time suffer varying degrees of heart disease or altered brain waves.In movies,sometimes the hero can produce a sound that ordinary people can’t hear and only those who have the same ability can feel.In nature,there is actuallysound that is beyond our hearing.In physics,the sound that exceeds20,000Hz is called ultrasonic.3It does no harm to health.Sound less than20Hz is called infrasonic waves.When we move,the air will vibrate.4As the frequency of infrasonic waves is close to that of people’s internal organs4,infrasonic wave may cause resonance in human bodies.As a result,people’s vision may weaken and internal organs may rupture.However,whether an infrasonic wave can be used as a weapon depends on its intensity5.If its intensity is very low,it won’t damage internal organs or a person’s health.5When wind blows at a force of3or4over the sea6,it will produce infrasonic waves of several decibels. Only typhoons can produce infrasonic waves of over100decibels.At present, scientists can only produce infrasonic weapons in the lab with the help of advanced scientific tools and powerful electric power.A High sound of150decibels can kill a healthy rat.B The vibration of air can produce infrasonic waves.C We cannot play high-pitched music with ordinary musical instruments.D If the intensity of infrasonic wave exceeds160decibels,it is extremely harmful.E Dolphins,whales and bats can make such high-frequency sound.F Therefore,the sound of ordinary musical instruments cannot harm your health.答案与题解:1.A本段要说明,音量超过80分贝,即使是美妙的音乐,对人体也有害,“空1”前面的句子说:一阵高分贝的强烈的冲击波能使一块铁板扭曲和破裂。
