2022年司法考试主观题紧急提分训练备考方法

2022年司法考试主观题紧急提分训练备考方法2022年的司法考试目前已经结束了客观题部分的考试,于此同时,距离主观题部分的考试也只剩下不到20天的时间留给考生们复习了,在这么紧张的时间里,小编为大家带来了2022年司法考试主观题紧急提分训练备考方法,供大家学习参考,欢迎大家阅读!2022年司法考试主观题提分备考方法第一,思路训练主观题的题目是比较长的,但是题干补偿,为了避免我们反复的去读题浪费时间,漏答重点法条等情况发生,所以我们在读题的时候,最好是在脑海中梳理一遍题目,把可能或者是需要用的的信息标注一下,这样避免自己会错过一些重点的考点信息。
第二,关键词定位法主观题是踩点得分,只要你写出大概的意思或者是关键词即可得分,大家要知道,在法考的考试中一分之差就可能直接导致你落考,所以在我们解题的过程中,部分题目涉及到一些难点,我们必须要进行拆分,然后结合自己的思路,按关键词拓展自己的结论。
第三,法条练习虽然说主观题是半开卷考试,但是一些重要的法条目录或者是位置我们一定要熟记,这样有利于我们在翻阅法条的时候可以快速准确的定位到自己所需要的法条目录中,减少不必要的时间浪费。
第四,案例分析多练在主观题考试中,案例分析题是我们练习的重点,刚开始的时候我们可以先从小案例开始联系,先熟悉主观题的案例套路,然后慢慢的转变为大型案例,一定要严格按照考试要求来练习,避免在正规考试中由于时间不够而出现未答完的情况法考的考试内容客观题考查包括卷一、卷二。

passages.Answer the questions below each passage by choosing A B C or D.Mark your answers on ANSWER SHEET1.(40points)Text OneThe importance and focus of the interview in the work of the print and broadcast journalist is reflected in several books that have been written on the topic.Most of these books,as well as several chapters,mainly in, but not limited to,journalism and broadcasting handbooks and reporting texts,stress the“how to”aspects of journalistic interviewing rather than the conceptual aspects of the interview,its context,and implications.Much of the“how to”material is based on personal experiences and general impressions.As we know,in journalism as in other fields,much can be learned from the systematic study of professional practice.Such study brings together evidence from which broad generalized principles can be developed.There is,as has been suggested,a growing body of research literature in journalism and broadcasting,but very little significant attention has been devoted to the study of the interview itself.On the other hand,many general texts as well as numerous research articles on interviewing in fields other than journalism have been written.Many of these books and articles present the theoretical and empirical aspects of the interview as well as the training of the interviewers.Unhappily,this plentiful general literature about interviewing pays little attention to the journalistic interview.The fact that the general literature on interviewing does not deal with the journalistic interview seems to be surprising for two reasons.First,it seems likely that most people in modern Western societies are more familiar,at least in a positive manner,with journalistic interviewing than with any other form of interviewing.Most of us are probably somewhat familiar with the clinical interview,such as that conducted by physicians and psychologists.In these situations the professional person or interviewer is interested in getting information necessary for the diagnosis and treatment of the person seeking help.Another familiar situation is the job interview.However,very few of us have actually been interviewed personally by the mass media,particularly by television.And yet,we have a vivid acquaintance with the journalistic interview by virtue of our roles as readers,listeners,and viewers.Even so,true understanding of the journalistic interview, especially television interviews,requires thoughtful analyses and even study,as this book indicates.21.The main idea of the first paragraph is that________.[A]generalized principles for journalistic interviews are the chief concern for writers on journalism[B]importance should be attached to the systematic study of journalistic interviewing[C]concepts and contextual implications are of secondary importance to journalistic interviewing[D]personal experience and general impression should be excluded from journalistic interviews22.Much research has been done on interviews in general________.[A]so the training of journalistic interviewers has likewise been strengthened[B]though the study of the interviewing techniques hasn’t received much attention[C]but journalistic interviewing as a specific field has unfortunately been neglected[D]and there has also been a dramatic growth in the study of journalistic interviewing23.Westerners are familiar with the journalistic interview,________.[A]but most of them wish to stay away from it[B]and many of them hope to be interviewed some day[C]and many of them would like to acquire a true understanding of it[D]but most of them may not have been interviewed in person24.The word“empirical”(Para.2)most probably means[A]hypothetical[B]practical[C]reciprocal[D]hysterical25.The text is most likely a part of a________.[A]news article[B]journalistic interview[C]research report[D]prefaceText2The future of space exploration depends on many things.It depends on how technology evolves,how political forces shape competition and partnerships between nations,and how important the public feels space exploration is.The near future will see the continuation of human space flight in Earth's orbit and unpiloted space flight within the solar system.Piloted space flight to other planets,or even back to the moon,still seems far away.Any flight to other solar systems is even more distant,but a huge advance in space technology could drive space exploration into realms currently explored only by science fiction.The1968film2001:A Space Odyssey depicted commercial shuttles flying to and from a giant wheel-shaped space station in orbit around Earth,bases on the moon,and a piloted mission to Jupiter.The real space activities of2001will not match this cinematic vision,but the21st century will see a continuation of efforts to transform humanity into a space faring species.Perhaps the most difficult problem space planners face is how to finance a vigorous program of piloted space exploration in Earth’s orbit and beyond.In1998no single government or international enterprise had plans to send people back to the moon,much less to Mars.Such missions are unlikely to happen until the perceived value exceeds their cost.One belief shared by a number of space exploration experts is that future lunar and Martian expeditions should be aimed at creating permanent settlements.The residents of such outposts would have to"live off the land,"obtaining such necessities as oxygen and water from the harsh environment.On the moon,pioneers could obtain oxygen by heating lunar soil.In1998the Lunar Prospector discovered evidence of significant deposits of ice,a valuable resource for settlers,mixed with soil at the lunar poles.On Mars,oxygen could be extracted from the atmosphere and water could come from buried deposits of ice.The future of piloted lunar and planetary exploration remains largely unknown.Most space exploration scientists believe that people will be on the moon and Mars by the middle of the21st century,but how they getthere,and the nature of their visits,is a subject of continuing debate.Clearly,key advances will need to be made in lowering the cost of getting people off Earth,the first step in any human voyage to other worlds.Space exploration experts have long hoped that as international tensions have eased,an increasing number of space activities could be undertaken on an international,cooperative basis.In addition to the economic savings that could result from nations pooling their resources to explore space,the new perspective gained by space voyages could be an important benefit to international relations.The Apollo astronauts have said the greatest discovery from our voyages to the Moon was the view of their own world as a precious island of life in the void.Ultimately that awareness could help to improve our lives on Earth.26.A flight to other solar systems will be made more possible by_________[A]technological breakthroughs.[B]international cooperation.[C]market competition.[D]public pressure.27.It can be inferred from Paragraph2that human society will become increasingly_________[A]worried about life on other planets.[B]dependent on space tourism.[C]accustomed to long-distance flights.[D]associated with space exploration.28.It is difficult to send people to other planets because of_________[A]lack of capacity of space exploration vehicles.[B]the financial expenditure involved in space travel.[C]controversial nature of space travel.[D]the uncertain future of space exploration.29.According to this text,piloted space missions will need to be_________[A]more exciting than earlier film versions.[B]supported by international organizations.[C]more cost-effective than they appear to be at present.[D]financed by individual governments.30.It is predicted that people who will live on other planets would have to_________[A]appreciate the harsh conditions they encounter there.[B]depend on the natural resources available there.[C]take most daily necessities along with them.[D]engage in scientific research.Text3Big Western oil firms were reporting their results for the third quarter as the oil price climbed towards$100 a barrel during the past few weeks.Record oil prices,it turns out,do not translate into record profits.Oil is now close to exceeding the record set in1979of between$100and$110,depending on how you adjust for inflation and what criterion you use.Yet almost without exception,big oil firms'profits are falling from the peaks reached last year.Exxon Mobil,for example,reported a10%drop in profits in the third quarter,and BP's fell even more sharply.Profits also fell at Chevron,ConocoPhillips and Eni.They rose at Total and Royal Dutch Shell—but only thanks to exchange-rate fluctuations and one-off asset sales.Analysts at Citigroup calculate that,measured in dollars,the biggest oil firms'earnings fell by15%on average.To be fair,the oil price has surged most dramatically since the end of September,although it was also buoyant in the third quarter.The majors'poor showing also reflects lower profits from refining,as the difference in price between petrol and crude oil has fallen from the exceptionally high levels of recent months.But the fact remains that oil giants are struggling to pump more oil and gas.In part,this is due to a quirk of the rules that oblige Western oil firms to share the crude they produce with state-owned oil firms in many countries.The contracts in question often rule that as the price goes up,the volume of oil the foreigners receive decreases.Worse,several countries are changing contracts or tax rules in ways that will further erode the Western oil firms'profits—and in some cases are throwing them out altogether.Rising costs are also a problem.Exxon,which is known for its strict financial discipline,saw costs rise almost twice as fast as revenue in the third quarter.The shortage of labor and equipment that is feeding this inflation is also causing delays to new projects.And there are not enough new projects in the pipeline.The International Energy Agency reckons that the expansion plans of the big Western and state-owned oil firms will leave the world12.5m barrels per day short of requirements in2015.Despite this looming deficit and the glaring price signal,all the big companies except Total produced less oil and gas in the third quarter than they did in the same period last year.According to Citigroup,the average decline in overall output was3.3%.If the relatively steady supply of natural gas is stripped out,the numbers look even worse:oil production fell by9%on average.No matter how high the price goes,the oil majors cannot make a profit from oil they do not produce.31.We can learn from the first paragraph that_______[A]the oil price is not really close to the degree of exceeding the historical record.[B]whether the oil price will break the record rests on the measurement used.[C]the oil price is rising and will continue rising to the historical record.[D]the profit of the oil production industry reached the historical record last year.32.Which one of the following statements is NOT true of the situation of the third quarter?[A]Most oil companies were suffering a serious loss in the third quarter.[B]Some companies also enjoyed rising profits in the third quarter.[C]The oil refining industry was also suffering a surplus reduction in the third quarter.[D]The oil price was on the rise in the third quarter.33.“This inflation”(Paragraph5)refers to_____[A]the rise of oil price.[B]the rise of Consumer Price Index(CPI).[C]the rise of oil production costs.[D]the rise of oil production revenue.34.The example of Citigroup is mentioned to______[A]show the big oil firms can benefit from the oil production[B]illustrate the Citigroup was the largest corporation with oil output[C]explain the causes for the average decline in the overall oil output[D]prove the prevalent trend of reduction in oil production35.Record oil prices do not translate into record profits because of the following reasons except_____[A]the declining margin from oil refining.[B]the disadvantageous change in contracts.[C]the shortage of supply of labour and equipment.[D]the decreasing quantity of oil production.Text4Dreams are said to be the window to the mind.Through the study of dreams,we can catch glimpses into what our subconscious minds are thinking,or what is troubling us at our deepest levels.No all dreams are the same,however,either in content or in meaning.In this respect,the study of bad dreams,nightmares,can yield interesting observations in regard to the mind and status of the dreamer.Indeed,nightmares appear to have been the subject of far more studies than more pleasant dreams,if for no other reason than while pleasant dreams are easily forgotten upon awakening,nightmares tend to linger in our minds is sufficient to demand attention.The sources of our dreams are most commonly attributed to factors in our waking lives.Whether it be emotional challenges,stress in the workplace,relationship problems or a myriad of other possible factors,the thoughts and feelings created in our waking environments are believed to directly influence the content of our dreams.A particular dramatic or traumatic experience during the day would no doubt be encountered again in some form or another during the night.Just as important as actual events in the determination of the content of our dreams are the pre-existing beliefs that we hold.If we encounter some kind of phenomena in our dreams,it is very likely that we already believed in the possibility of the phenomena before the dream.For example,if someone dreams of being abducted by aliens,it’s very likely that,before the dream,he already believed in the existence of aliens.To the extent that dreams are direct reflections of our minds,they will reflect accurately what we believe and hold to be true.The way that we act in dreams bears consideration as well.Often times,our behavior in our dreams reflects hidden desires for that type of behavior in our waking lives.Someone who dreams of revenge may actually desire revenge in real life,and likewise someone who dreams of adventure night after night may be experiencing his mind playing out a desire for more excitement in his everyday life.While the items encountered in our dreams are of great importance in the analysis of dreams,it must be recognized and understood that the same item in two different dreams can easily have entirely different meanings for the two dreamers.For example,a horse in the dreams of an avid equestrian can signify comfort and relaxation,whereas the same horse in the dreams of a hunter can represent excitement and challenge.36.Nightmares are mentioned in paragraph one in order to______[A]give an introduction of our subconscious mind.[B]give an example of one particularly vivid type of dream.[C]provide a justification for the study of influence of dreams.[D]compare the pleasant dreams and nightmares.37.Based on the information provided in paragraph three,if a man dreamed of being hit by a train,it is likely that he_______[A]has been hit by a train before.[B]beliefs in the existence of trains.[C]believes that it is possible to be hit by a train.[D]is afraid of being hit by a train.38.The last sentence of the text gives an example of horses encountered in dreams of two different people in order to______[A]illustrate how the same item can mean different things in different dreams.[B]exemplify the concept that people would,no doubt,react differently to the same images in dreams.[C]illustrate the idea that the emotions can influence the contents of dreams.[D]Support the assertion that the meaning behind dream images is entirely subjective.39.The main point of the text is that_______[A]the study of dreams is based on logic from the waking life of the dreamer.[B]in order to understand the meaning of dreams,we must analyze the beliefs of the dreamers.[C]dreams can reveal much about the personality of the dreamer.[D]the study of nightmares,while multifaceted,is a worthwhile endeavor.40.Which of the following would the author most likely agree with?[A]Nightmares can be good for us,if we use it properly.[B]Those who study dreams must first study the emotion of the dreamer.[C]The study of dreams makes sense if we know what to look for.[D]Dreamers should pay attention to their dreams to discern what those dreams reveal about themselves.Part BDirections:You are going to read a text about the tasks of leaders and the skills required for leadership.Choose the most suitable heading from the list A-G for each numbered paragraphs(41-45).The first and the last paragraph of the text are not numbered.There is one extra heading which you do not need to use.Mark your answers on ANSWER SHEET1(10points).[A]Handling rights based disputes[B]The role of dependence in disputes[C]Methods of settling conflicting interests[D]The use of negotiation for different dispute types[E]Advantages of negotiation over mediation[F]The role of power in settling disagreements[G]Disagreement of interestsThe Nature of DisputesTo resolve a dispute means to turn opposing positions into a single outcome.The two parties may choose to focus their attention on one or more of three basic factors.They may seek to(1)reconcile their interests,(2) determine who is right,and/or(3)determine who is more powerful.41Interests are needs,desires,concerns,fears一the things one cares about or wants.They provide the foundation for a person's or an organization's position in a dispute.In a dispute,not only do the interests of one party not coincide with those of the other party,but they are in conflict.For example,the director of sales for an electronics company gets into a dispute with the director of manufacturing over the number of TV models to produce.The director of sales wants to produce more models because her interest is in selling TV sets;more models mean more choice for consumers and hence increased sales.The director of manufacturing,however,wants to produce fewer models.His interest is in decreasing manufacturing costs and more models mean higher costs.42Reconciling such interests is not easy.It involves probing for deeply rooted concerns,devising creative solutions, and making tradeoffs and compromises where interests are opposed.The most common procedure for doing this is negotiation,the act of communication intended to reach agreement.Another interests based procedure is mediation,in which a third party assists the disputants,the two sides in the dispute,in reaching agreement.43By no means do all negotiations(or mediations)focus on reconciling interests.Some negotiations focus on determining who is right,such as when two lawyers argue about whose case has the greater merit.Other negotiations focus on determining who is more powerful,such as when quarrelling neighbors or nations exchange threats and counter threats.Often negotiations involve a mix of all threesome attempts to satisfy interests,some discussion of rights,and some references to relative power.44It is often complicated to attempt to determine who is right in a dispute.Although it is usually straightforward where rights are formalized in law,other rights take the form of unwritten but socially accepted standards of behavior,such as reciprocity,precedent,equality,and seniority.There are often different―and sometimes contradictory standards that apply to rights.Reaching agreement on rights,where the outcome will determine who gets what,can often be so difficult that the parties frequently turn to a third party to determine who is right. The most typical rights procedure,in which disputants present evidence and arguments to a neutral third party who has the power to make a decision that must be followed by both disputants.(In mediation,by contrast,the third party does not have the power to decide the dispute.)Public adjudication is provided by courts and administrative agencies.Private adjudication is provided by arbitrators.45A third way to resolve a dispute is on the basis of power.We define power,somewhat narrowly,as the ability to pressure someone to do something he would not otherwise do.Exercising power typically means imposing costs on the other side or threatening to do so.The exercise of power takes two common forms:acts of aggression, such as physical attack,and withholding the benefits that derive from a relationship,as when employees stop working in a strike.Section III TranslationDirections:Directions:Read the following text carefully and then translate the underlined segments into Chinese.Your translation should be written clearly on ANSWER SHEET2.(10points)I came away from my years of teaching on the college and university level with a conviction that enactment,performance,dramatization are the most successful forms of teaching.Students must be incorporated, made,so far as possible,an integral part of the learning process.(46)The notion that learning should have in it an element of inspired play would seem to the greater part of the academic establishment merely silly,but that is nonetheless the case.(47)Of Ezekiel Cheever,the most famous schoolmaster of the Massachusetts Bay Colony, his onetime student Cotton Mather wrote that he so planned his lessons that his pupils"came to work as though they came to play,"and Alfred North Whitehead,almost three hundred years later,noted that a teacher should make his/her students"glad they were there."(48)Since,we are told,80to90percent of all instruction in the typical university is by the lecture method, we should give close attention to this form of education.There is,I think,much truth in Patricial Nelson Limerick's observation that"lecturing is an unnatural act,an act for which God did not design humans.It is perfectly all right,now and then,for a human to be possessed by the urge to speak,and to speak while others remain silent.But to do this regularly,one hour and15minutes at a time for one person to drag on while others sit in silence?I do not believe that this is what the Creator designed humans to do."(49)The strange,almost incomprehensible fact is that many professors,just as they feel obliged to write dully,believe that they should lecture dully.To show enthusiasm is to risk appearing unscientific,unobjective;it is to appeal to the students'emotions rather than their intellect.Thus the ideal lecture is one filled with facts and read in an unchanged monotone.The cult of lecturing dully,like the cult of writing dully,goes back,of course,some years.Edward Shils, professor of sociology,recalls the professors he encountered at the University of Pennsylvania in his youth. They seemed"a priesthood,rather uneven in their merits but uniform in their bearing;they never referred to anything personal.Some read from old lecture notes and then haltingly explained the thumb-worn last lines. Others lectured from cards that had served for years,to judge by the worn edges...(50)The teachers began on time,ended on time,and left the room without saying a word more to their students,very seldom being detained by questioners...The classes were not large,yet there was no discussion.No questions were raised in class,and there were no office hours."Section IV WritingPart ADirections:A chemical plant should be responsible for the water pollution in a nearby river.Write a letter to the City Environment Protection Agency to1)state the present situation,2)suggest ways to deal with the problem and3)express your sincere hope.You should write about100words on ANSWER SHEET.Do not sign your own name at the end of the letter.

(15)ERA Optical Modules (16)ERA Racks (18)Accessories (19)Universal Access Points (UAP) and Mounting Kits (21)ERA C-RAN antenna system is built on C-RAN architecture that consolidates and simplifies distributed antenna system head-end resources and flexibly allocates capacity where and when it’s needed across the covered area through a simple drag-and-drop software interface.Cloud and centralized radio access networks (C-RAN) represent a shift in the way operators are managing wireless capacity. This breakthrough architecture offers substantial advantages in both capex and opex. ERA extends C-RAN advantages to in-building wireless solutions.Like a distributed antenna system, CommScope’s ERA C-RAN antenna system employs a network of interconnected antennas that provide users access to the wireless network. However, unlike traditional distributed antenna system solutions, CommScope’s C-RAN antenna system coordinates wireless capacity throughout a campus, office park or even a metro area from a centralized head-end location or even from operators’ existing C-RAN hubs.ERA ® C-RAN Antenna SystemBenefits•Consolidates baseband functions into a single, less complex head-end instead of requiring one in each building •Flexibly and dynamically allocates baseband capacity across many buildings•Requires less fiber and can even share fiber with other services for major deployment cost savingsModular, Frequency Agnostic Building BlocksSystem Configuration•All components support all frequency bands •IT physical layer infrastructure converged•Automatic configuration and dynamic optimization•Advanced operational, optimization,and troubleshooting capabilitiesERA makes it easy to deploy, confi gure and optimize in-building wireless solutions. A small set of frequency-independent building blocks is all that’s required for complete fl exibility and scalability, from small offi ce buildings to large, complex venues.CANWIN TENHead-End - NodesAccess Points - UAP and CAPUAPCAP LCAP MCAP HFiber or Cat6A FiberCat6AHead-End: Attenuators, e-POI Subrack and ModulesERA’s universal 4U e-POI rack supports up to 8 RF modules.

2022中国尿素循环障碍诊断治疗和管理指南(全文)

2022中国尿素循环障碍诊断治疗和管理指南(全文)摘要尿素循环障碍是一组致残率高、致死率高的遗传代谢性疾病。
为提高我国相关领域医生对该病的诊疗管理水平,特制订“中国尿素循环障碍诊断治疗和管理指南”,基于当前可获得的临床证据,针对尿素循环障碍诊断、治疗和管理相关12个临床问题提供了对应参考意见。
尿素循环障碍(urea cycle disorders,UCD)是指因参与尿素循环的酶和转运蛋白缺陷,导致氨基酸分解代谢产生的氨不能通过尿素循环形成尿素排出体外,引起血氨升高为特征的一组遗传代谢病,代谢通路见图1。
国外报道UCD新生儿的发病率约为1/35 000,致残率高、病死率高。
不同亚型包括鸟氨酸氨甲酰基转移酶缺乏症(ornithine transcarbamylase deficiency,OTCD)、N-乙酰谷氨酸合成酶缺乏症(N-acetylglutamate synthase deficiency,NAGSD)、氨甲酰磷酸合成酶1缺乏症(carbamoylphosphate synthetase 1 deficiency,CPS1D)、精氨酰琥珀酸合成酶缺乏症(argininosuccinate synthetase deficiency,ASSD)、精氨酰琥珀酸裂解酶缺乏症(argininosuccinatelyase deficiency,ASLD)、精氨酸酶1缺乏症(arginase 1 deficiency,ARG1D)、高鸟氨酸血症-高氨血症-同型瓜氨酸尿症综合征(hyperornithinaemia-hyperammonaemia homocitrullinuriasyndrome,HHHS)和希特林蛋白缺乏症(Citrin deficiency,Citrin D)。
各亚型发病率存在差异,以高氨血症为特征性表现的亚型中OTCD最常见,发病率为1/80 000~1/5 650。
