寄生虫重修题库

【临床本科第七版寄生虫课本为参考书】总论部分填空题不同生物的共同生活现象分为共栖、共生、寄生。

按照寄生虫生活史过程中是否需要中间宿主,生活史类型分为直接型、间接型。

寄生虫的宿主类型包括中间宿主、终宿主、保虫宿主、转续宿主。

寄生虫对宿主的毒害作用表现为夺取营养、机械损伤、毒素和免疫病理损害三个方面。

.常见的寄生虫侵入人体的传播途径包括经口感染、经皮肤感染、经呼吸道感染经输血感染等。

名词解释1.异位寄生现象:有些寄生虫在常见的寄生部位以外的组织或器官寄生的现象。

可引起异位的损害,出现不同的症状和体征。

2.幼虫移行症:指一些蠕虫幼虫侵入非正常宿主后不能发育为成虫,但是这些幼虫可以在宿主体内移行引起局部或全身病变的现象。

3.寄生:两种生物生活在一起,其中一方获利,而另一种生物受到损害,这种关系称为寄生。

4.寄生虫:寄生生活中获得利益的原虫、蠕虫和节肢动物等低等动物。

5.宿主(host):在寄生生活中被寄生虫寄生,提供寄生虫营养和居住场所,并受其伤害的人或动物。

6.生活史:寄生虫完成一代生长、发育和繁殖的过程。

7.世代交替:寄生虫在完成一代生活史过程中兼备有性生殖和无性生殖的现象。

8.终宿主(definitive host):寄生虫的成虫或有性生殖阶段所寄生的宿主。

9.中间宿主(intermediate host):幼虫或无性生殖阶段寄生的宿主。

10.机会致病寄生虫:通常处于隐性感染状态。

当宿主免疫功能低下时出现异常增殖并致病。

11.感染阶段是指寄生虫能侵入人或动物宿主体内的阶段。

12.人体感染寄生虫后,可对再感染产生一定程度的免疫力,但对其体内原有的寄生虫不能完全清除,而维持在一个低水平,并对同种寄生虫再感染具有一定的抵抗力,此种免疫状态称带虫免疫。

四、问答题1. 寄生虫有哪些生活史类型,并举例说明答寄生虫生活史类型以是否需要中间宿主划分为直接型生活史和间接型生活史。

直接型生活史不需要中间宿主,寄生虫的虫卵或幼虫在外界直接发育为感染阶段感染人。

Part II Reading Comprehension (40%) Directions: There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre. Passage One Questions 26 to 30 are based on the following passage. The United States court system, as part of the federal system of government, is characterized by dual hierarchies(双重等级): there are both state and federal courts. Each state has its own system of courts, composed of civil and criminal trial courts, sometimes intermediate courts of appeal(上诉), and a state supreme court. The federal court system consists of a series of trial courts (called district courts) serving relatively small geographic regions (there is at least one for every state), a tier of circuit courts of appeal that hear appeals from many district courts in a particular geographic region, and the Supreme Court of the United States. The two court systems are to some extent overlapping(重叠), in that certain kinds of disputes (such as a claim that a state law is in violation of the constitution) may be initiated in either system. They are also to some extent hierarchical, for the federal system stands above the state system in that litigants (persons engaged in lawsuits) who lose their cases in the state supreme court may appeal their cases to the Supreme Court of the United States. Thus, the typical court case begins in a trial court--a court of general jurisdiction(审判权)-- in the state or federal system. Most cases go no further than the trial court: for example, the criminal defendant is convicted (by a trial or a guilty plea) and sentenced by the court and the case ends; the personal injury suit results in a judgment by a trial court (or an out-of-court settlement by the parties which the courts suit is pending) and the parties leave the court system. But sometimes the losing party at the trial court cares enough about the cause may appeal to the next higher court 26. What does the passage mainly discuss? A) Civil and criminal trial courts. B) Trial court cases. C) The court system in the United States. D) The appeal court process. 27. According to the passage district courts are known as ________. A) circuit courts B) supreme courts C) intermediate courts D) trial courts 28. In the last sentence of the first paragraph, the phrase "engaged in" could best be replaced ________. A) committed to B) involved in C) attentive to D) engrossed in 29. The passage indicates that litigants who lost their cases in the state trial court may take them to a ________. A) different trial court in the same state B) court in a different geographic region C) federal trial court D) state supreme court 30. It can be inferred from the passage that typical court cases are ________.学院: ________________ 姓名: ________________ 学号: ________________ 任课教师: ______________ 考试科目: ________________- ------------------- ------------ ----------------------密封线-------------------------------------------------------- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -A) always appealedB) usually resolved in the district courtsC) always overlappingD) usually settled by the supreme courtPassage TwoQuestions 31 to 35 are based on the following passage.Learning how to write is like taking a course in public speaking. I'd ask whether anyone in class had ever taken such a course. Invariably a few hands would go up."What did you learn in that course?" I'd ask."Well, the main thing was learning how to face an audience ... not to be inhibited(拘谨) ... not to be nervous ..."Exactly, when you take a course in public speaking nowadays, you don't hear much about grammar and vocabulary. Instead, you’re taught how not to be afraid or embarrassed, how to speak without a prepared script, how to read out to the live audience before you. Public speaking is a matter of overcoming your long-standing nervous inhibitions.The same is true of writing. The point of the whole thing is to overcome your nervous inhibitions, to break through the invisible barrier t hat separates you from the person who’ll read what you wrote. You must learn to sit in front of your typewriter or dictating machine and read out to the person at the other end of the line.Of course, in public speaking, with the audience right in front of you, the problem is easier. You can look at them and talk to them directly. In writing, you’re alone. It needs an effort of your experience or imagination to take hold of that other person and talk to him or her. But that effort is necessary--or at least it's necessary until you've reached the point when you quite naturally and unconsciously "talk on paper".31. The topic of the passage is ________.A) how to be a good writerB) how to be a good speakerC) how to express yourself with your wordsD) how to get rid of nervousness in public speaking32. The public speech course mainly teaches students ________.A) how to make an attractive speech using perfect grammar and vocabularyB) how to express themselves exactly and vividlyC) how to collect data needed and organize itD) how to get over their nervousness when making a speech.33. The similarity between making a public speech and writing is that ________.A) you have to do a lot of preparation work beforehandB) you should get over your nervous inhibitionsC) you should know grammar and vocabulary well to accomplish themD) both of them have audience34. In the opinion of the author, public speaking is much easier than writing because ________.A) public speaking requires less effort than writingB) it's unnecessary for you to write a lot for speech and you can say anything as you likeC) you face the audience directly in public speaking; while writing is otherwiseD) in public speaking, the audience has to listen to you whether they like it or not35. The author of this passage probably is a ________.A) boss B) politician C) writer D) professorPassage ThreeQuestions 36 to 40 are based on the following passage.Do you find getting up in the morning so difficult that it's painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.During the hours when you labor through your work you may say that you're "hot". That's true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the forenoon. For others it comes in the afternoon or evening. No one has discovered why it is so, but it leads to such familiar monologues(自言自语) as: "Get up, John! You’ll be late for work again!" The possible explanation to the trouble is that John is at his temperature - and - energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.You can't change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe you’re sleepy in the evening but feel you must stay up late anyway. Counteract(对抗) your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won't change your cycle, but you'll get up steam and work better at your low point.Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.36. If a person finds getting up early a problem, most probably ________.A) he is a lazy personB) he refuses to follow his own energy cycleC) he is not sure when his energy is lowD) he is at his peak in the afternoon or evening37. Which of the following may lead to family quarrels according to the passage?A) Unawareness of the energy cycles.B) Familiar monologues.C) A change in a family member's energy cycle.D) Attempts to control the energy cycle of other family members.38. If one wants to work more efficiently at his low point in the morning, he should ________.A) change his energy cycleB) overcome his lazinessC) get up earlier than usualD) go to bed earlier39. You are advised to rise with a yawn and stretch because it will ________.A) help to keep your energy for the day's workB) help you to control your temper early in the dayC) enable you to concentrate on your routine workD) keep your energy cycle under control all day.40. Which of the following statements is NOT TRUE?A) Getting off to work with a minimum effort helps save one's energy.B) Dr. Kleitman explains why people reach their peaks at different hour of day.C) Habit helps one adapt to his own energy cycle.D) Children have energy cycles, too.Passage FourQuestions 41 to 45 are based on the following passage.Today, more and more people are using credit cards instead of money to buy the things they need. Almost anyone who has a steady income and a continuous work record can apply for a credit card.If you have a credit card, you can buy a car, eat a dinner, take a trip, and even get a haircut by charging the cost to your account. In this way you can pay for purchases a month or two later, without any extra charge. Or you may choose to spread out your payments over several months and pay only part of the total amount each month. If you do this, the credit card company or the bank that sponsors(经办) the credit card will add a small service charge to your total bill. This is very convenient for the customer. With the credit card in your wallet or purse, you don't have to carry much cash. This saves you trips to the bank to cash checks or withdraw cash. Also if you carry credit cards instead of a lot of cash, you don't have to be concerned about losing your money through carelessness or theft. The card user only has to worry about paying the final bill. This of course can be a problem if you charge more than you can pay for.Credit cards are big business. Americans spend $ 16 billion a year on cards and there are already 590 million of them in circulation. Many banks sponsor their own credit card companies and issue cards free to their customers. Other credit card companies charge their member annual dues(费用). The stores that accept credit cards must pay a small fee to the credit card company--a percentage of the purchase price of the merchandise or service. In turn, the credit card company promptly pays the store for the merchandise or service. Credit card companies make a profit from the fees they charge the store and also from the fees collected from customers who pay for their charges in monthly installments. However, credit card companies sometimes have problems collecting undue payments from unreliable customers. Also the use of stolen, lost, or counterfeit(伪造的) credit cards by criminals has become a big headache for the credit card company that is responsible for the goods and services illegally charged to its customers' account.41. The main purpose of this passage is ________.A) to promote the sale of credit cardsB) to persuade you not to buy credit cardsC) to explain credit card economyD) to give you some instructions on how to use the credit card42. Why are more and more people using credit cards?A) Because they are becoming richer and richer.B) Because everyone can apply for the credit card.C) Because it is cheap to buy goods by using a credit card.D) Because it is convenient for them to buy goods.43. According to the author, which of the following statements is NOT TRUE?A) With a credit card you can pay for purchases two months later.B) With a credit card you can charge the cost to your account.C) With a credit card you don't have to be worried about a thief.D) With the credit card you don’t have to worry about your final bill.44. In the passage, "Credit cards are big business" means thatA) credit card banks earn a lot of moneyB) credit cards are sold at a high priceC) every customer has bought a credit cardD) customers must pay a lot of money to the credit card companies45. The credit card companies have difficulties in ________.A) charging goods and services to their customers' accountB) gathering overdue paymentsC) finding the owners of lost credit cardsD) selling their cards。

For each of them there are four suggested answers marked A, B, C and D. Choose the best answer to each question. Then you should mark the corresponding letter on the Answer Sheet with a single line through the center.Passage OneOne day in 1754, a man went to the market in Florence, Italy, and bought some meat. The shopkeeper wrapped the meat in a piece of paper and the man took it home. When he unwrapped the meat, he was surprised to see some old writing on the paper.This man was in charge of the public library, so he knew a lot about old books and old writing. He realized that the paper was a page of scientific notes."Only one man wrote like that," the librarian said to himself. "It was Galileo who wrote these notes!"Who was Galileo? Galileo was a famous Italian scientist. He was a man of ideas, but he was also a man of action. He made many experiments in order to find out more about the earth and the universe. Galileo believed that scientists should not only sit in universities and talk about theory; they should also make practical experiments and learn from the results.Galileo wrote down notes of all the experiments he made. After Galileo's death in 1642, Viviani, one of his students, collected the notes together and put them into his own library. However, when Viviani died, nobody looked at Galileo's notes any longer. For many years, people forgot about them.The librarian hurried back to the market and asked the shopkeeper where he had got the paper from. The shopkeeper led him to the house where he bought the paperfrom. In the house, the librarian found many more of Galileo's notes. The family gave them to him.In this way, a large number of important notes about Galileo's experiments were saved.31.The librarian got Galileo's notes from ____.A the butcherB VivianiC a family living in Viviani's houseD the market near Viviani's house32.Which statement about Galileo is NOT true?A He was full of ideas.B He did a lot of experiments.C He was an Italian.D He gave his notes to Viviani.33.Which statement about Viviani is NOT true?A He kept Galileo's notes.B He was Galileo's student.C He passed on the notes to his daughter.D He was as famous as Galileo.34.After Viviani's death, the notes ____.A were given to one of his friendsB were left somewhere in his houseC were lostD lost its value35.It can be inferred from the story that ____.A the family was unaware that they had Galileo's notesB the librarian bought the notesC Viviani gave the notes to the familyD the shopkeeper informed the librarian of the notesPassage TwoA favorite story among acoustical (声学的) experts concerns a noisy Long Island suburb where, day and night, huge trucks thundered down a freeway, jet planes roared overhead, and a pumping station maintained a low, continuous thumping. One night all mechanical sounds stopped briefly; immediately half the people in the neighborhood awoke, sat upright, and exclaimed: "What was that?"Americans are drowned in noise, one of the unwanted and unnecessary waste products of the twentieth century. Scientists speak of noise in decibels -- units by which they measure the intensity levels of the sound waves that beat against our eardrums. The shuffling of paper in silent surroundings represents about 15 decibels;a low conversation, 40 decibels; and the sound of an automobile horn, 90 decibels. In general, sounds above 80 decibels begin to irritate the human ear. Noise also causes increased muscular tension, which at night may deprive the body of rest.Experiments have shown that 160 decibels of noise are fatal for small fur-bearing animals. Although equal exposure is not fatal to man, it may destroy hearing. Over the past thirty years the loudest sounds to which man has been exposed have increased from 120 decibels, the equivalent of the roar of a two-engine propeller plane, to 150 decibels, the blast of a four-engine jet. This is an average increase in volume of one decibel a year, and constitutes a potentially dangerous source of physical damage.36.The story about a Long Island suburb is retold in order to show that ______.A we may find it easier to fall asleep in noisy surroundingsB contrary to popular belief, mechanical sounds are bearableC nowadays suburbs are not just as quiet as we expectD noise pollution has become a very serious problem37.The author refers to noise as ______.A an undesirable waste productB an unnecessary mechanical soundC a source of mental illnessD a measurement of the intensity ofsound waves38.Noise may interfere with man's sleep by ______.A causing him to have terrible dreamsB distracting his attentionC increasing his muscular tensionD keeping him restless39.Sounds of 160 decibels may ______.A be the loudest man can imageB do physical damage to manC cause certain small animals to dieD Both B and C.40.The author's purpose in writing this passage is to ______.A draw our attention to the importance of controlling noiseB show that man has more tolerance than animals when exposed to noiseC give a brief introduction to sound measurementD illustrate that noise is a by-product of modernizationPassage ThreeIn recent years, large numbers of people are living a single life, at least temporarily, for this reason or other. However, they are often pressured to marry by their families and friends, who regard single adults as irresponsible and unfortunate.Rose and Bill talk about the frustrations and disagreements. Rose has quarreled with her family. Her parents continually ask her why she doesn’t get married and have been putting pressure on Rose to find a husband. This makes Rose angry.Bill understands how Rose feels. He has also been upset about how his friends react to his single life. His women friends usually find him dates even if he doesn’t want them. They introduce him to new people as the eligible bachelor. Sometimes Rose and Bill feel they might be better off financially if they each found a marriage partner. They know that two people living together and earning two salaries can afford more than a single person can. They also know about the income tax advantages that married couples enjoy. However, for the moment, each of them is committed to remaining single.Young people feel man pressures not to get married. Rose has a very good job at the bank and there is a possibility of a promotion in the near future. A promotion means a higher salary and more responsibility.She questions whether she can combine success in business with marriage. How can she fully and completely take care of a wife’s duties while she can also succeed brilliantly in her office? Both demand a great amount of time and work.Bill, too, is hesitant about getting married because of his active social life. He has many friends and is out with one of them almost every night. Hoe can he ever settle down and stay home with one person? Will he lose his friends?At this point Rose and Bill are each trying to settle the questions of whether to get married or stay single. After all, marriage means responsibility. Both Rose and Bill know they will reach a decision without being pressured.41. Rose is frustrated by her family’s______.A. constant pressure on her to get marriedB. unwillingness to accept Bill into the familyC. ignorance of her career potentialD. all of the above42.

Then you should mark the corresponding letter on the Answer Sheet with a single line through the center.Little children have somehow got the impression that the definition of song is “what you hear 46 singing on the radio”. And when teachers try to 47 these children that they 48 sing, the kids just don’t see the point. Why should they struggle to perform a graceless version that only their mothers could possibly love? It’s so much easier to buy a CD and hear someone do it really well! Their logic is hard to argue 49 and it’s a direct result of our society’s obsession with competence. Pleasure is no longer the 50 of our leisure activities; in fact no one even sees anything pleasant 51 doing something less than perfectly well. This is crazy. And it’s 52 a terrible toll. Not only 53 depriving ourselves of creative satisfaction and discouraging our children from finding joy in 54 they can do themselves, we’re also destroying our artists.
