2009年全国高考宁夏区试题答案(理综)
2009年普通高考宁夏区试题(理综)

浅谈共青人精神第一次听到“共青人”、“共青人精神”是在今年年初,我刚进入共青团这个美丽的大家庭,就拥有“共青人”这样崇高的称谓,和其他(她)“共青人”一起奋斗在共青团的工作战线上。
于是,我潜心思考什么是“共青人精神”,并亲自去实践这种精神。
下面就我的“共青人精神”谈几点见解。
一、谦虚谨慎、勤奋好学在共青团这个大家庭里,青年就是指的18—35周岁。
尤其是18—28周岁这个年龄段的同志年轻气盛,阅历肤浅,冲劲十足,有敢为人先的气势,这是对的,但是把握不好不度就会给人一种心高气傲的感觉,往往会给身边的同志、朋友带来伤害和反感。
因此,我们年轻同志在言谈举止当中一定要谨慎行事、谦虚待人,低调做人、多向身边的同志学习,向朋友请教、做一名稳重踏实的青年。
在学习上有这样一句名言:“书山有路勤为径、学海无涯苦作舟”。
这句话其实已经告诉了我们学习的重要性,我们青年无论是在校深造还是投入社会或是就业从事某项工作,我们都应该坚持学习不放松的原则。
当然要正确认识学习的问题,不是为了学习而学习,而是要把握好学习的准确性,拓展学习的氛围,从学习党的路线、方针、政策到学习业务知识、科学技能、延伸至历史、政治、经济等方方面面更重要的是要学深、学懂、学精。
自古以来就有勤奋学习的典故。
比如:“闻鸡起舞,凿壁借光、头悬梁、锥刺骨”等等,如今,我们拥有这么好的学习环境,学习条件,怎能有不学习的道理呢?青年朋友们请记住吧:“人活到老,学到老”。
二、爱岗敬业,开拓创新年轻同志大都有这样一种习惯,就是喜新厌旧,这对某种事物或东西也就不足为奇了。
但是对待工作那就应该求真务实,脚踏实地,热爱自己的工作(事业),做到“干一行、钻一行、学一行、爱一行”,在工作上不能墨守陈规。
固步自封,要充分发挥年轻人的想象力,将好的思维、好的想法因地制宜的贯彻到工作中去,着重要创新思维,创新理念,创新方法,使自己的工作标新立异,切实可行。
有的同志会说:“我干的工作压力大或岗位不好”。

非财务管理的会计学学习体会项目管理部杨玉冰2011年7月30-31日,这两天聆听了杜兴强教授(厦门大学会计系教授、博导)为我们讲授的《非财务经历的会计学》一课。
杜教授深入浅出,用通俗易懂的语言、生灵活现的案例,使我对非财务管理的会计学有了初步的了解。
杜教授主要从以下几个方面讲述:1、财务会计基础知识:制度背景与会计准则2、基本财务报表3、资产4、负债及效益5、收入、费用与利润6、财务报表及其初步分析7、财务报表的操纵本次课程的重点是帮助非财会人员如何读懂财会报表,分析财务状况和经营成果,规避财务风险;利用预算管理手段,提高公司管理的效率和科学水平。
要了解一家企业的情况,首先要看这家企业的财务报表,企业的财务报表是对企业财务状况、经营成果和现金流量的结构性描述。
财务报表至少应当包括:资产负债表、利润表、所有者权益(或股东权益)变动表、现金流量表。
资产负债表反映企业现在的健康状况如何,利润表、反映企业的过去“怎么样”,现金流量表透视企业的将来“怎么样”。
其中最主要的是资产负债表,它能反映企业的家底是否殷实,资产规模与结构、负债规模与结构、资产质量情况、所有者权益构成、综合反映企业所拥有或控制的经济资源及其具体分布、有助于分析、评价及预测企业的偿债能力、财务弹性、经营业绩。
其次,要分析企业的资产。
资产的本质是未来的经济效益,它必须能够为企业所拥有或控制,必须是企业由于过去的交易或事项而形成,并且,资产作为一个要素在财务报表上进行确认,必须能够以货币进行计量。
资产分为:硬资产、虚资产、软资产、应收账款、坏账、固定资产、无形资产等。
第三要看企业的负债及权益,负债是由于企业过去的交易或事项而形成,必须是一项强制性的义务,负债在将来必须通过支付资产或提供劳务的方式来清偿,是能够用货币确切计量或合理估计的债务责任,一般都有确切的受款人和偿付日期。
所有者权益,是指所有者在企业资产中享有的经济效益,其金额为资产减去负债后的余额,在资产负债表上,所有者权益应当按照实收资本(或者股本)、资本公积、盈余公积、未分配利润等项目分项列示。

2009年高考宁夏卷(理综生物 新课标卷)试题及各题答案详解

An initial investigation on the use of ‘Return on Investment”in public relations practiceAbstract‘Return on Investment’(ROI) is usually defined in management and marketing literature as a measure of financial effectiveness that is concerned with the returns on capital employed in business (profit-making) activities. In public relations practice, however, ROI appears to be used in a much looser form to indicate the results of activity. This quantitative research using an online survey instrument investigated practitioner understanding of the term, primarily in the UK, with the aim of preparing a benchmark on their understanding of the ROI concept and usage of ROI as a measurement of the effectiveness of public relations activity. These findings resulted: (1) two-thirds of PR practitioners regularly use the term ROI when planning and evaluating communication activity; (2) ROI is related mainly to communication objectives (66.7%) which are more widely used than financially related ROIs (12.8%); (3) there is a clear difference in ROI practices between consultants/freelances and in-house colleagues. Nearly three-quarters of consultants and freelances (73.1%) offered an ROI formula to clients but only 26.3% of in-house practitioners have one; and (4) on the oft-discussed question of an industry-wide ROI formula, only 35.6% supported the proposition with 64.4% opposed. The survey also found that practitioner concepts of ROI are very narrowly expressed, mainly in relation to media outputs.Highlights►Two-thirds of PR practitioners regularly use the term ROI when planning and evaluating communication activity. ►ROIs related to communication objectives (66.7%) are much more widely used than financially related ROIs (12.8%). ►There is a clear difference in ROI practices between consultants/freelances and in-house colleagues.

IntroductionReturn on Investment (ROI) is defined in management and marketing literature as an outcome performance measure of financial effectiveness that is concerned with returns on capital employed in business (profit-making) activities ( [Drury, 2007] and [Moutinho and Southern, 2010]). The Dictionary of Public Relations Measurement and Research places ROI as “an outcome variable that equates profit from investment”but does not attempt to classify a ‘public relations ROI’, other than as a “dependent variable”(Stacks, 2006, p. 24). The UK professional body, the (now) Chartered Institute of Public Relations defined it as “a ratio ofhow much profit or saving is realised from an activity, as against its actual cost which is often expressed as a percentage”(IPR/CDF, 2004, p. 15). In public relations practitioner practice, however, ROI appears to be used in a much looser form to indicate the results of activity.The term has been in public relations discourse for at least 40 years. Black (1971) commented that it was “fashionable”to measure ROI in business, “but in the field of public relations it has little significance”(p. 100). In the late 1970s, ROI was sometimes expressed as equivalent to advertising value (Marker, 1977). Watson (2005) found that the term was not widely used or recognised in academic discourse. However, Gaunt and Wright (2004) found that 88% of a sample of international public relations practitioners was interested in an ROI tool and 65% considered that ROI could be applied to judgements on public relations effectiveness.Gregory and Watson (2008) also noted that use of the term ROI was extant in practice and called for greater academic engagement with practice issues such as the use of business language, including ROI, and communication scorecards.Professional literature and practitioner discourse (cf. European Measurement Summits and the IPR Measurement Summits), however, clearly show that ROI is a term widely used, if not tightly defined. In 2004, the UK media analysis firm Metrica undertook a study for the (then) Institute of Public Relations which found that 34% of respondents considered public relations budgets in terms of ROI and 60% used a notion of ROI to measure public relations in some way. It summarised the responses as, “some inclination towards seeking a form of ROI that could be applied universally”(IPR/CDF, 2004, p. 6) As well, Likely, Rockland, and Weiner (2007) proposed alternatives to ROI with four models which each have a ‘Return on’prefix.2. Research method and instrumentTo investigate the current state of attitudes amongst public relations practitioners about their notions of ROI, a scoping survey was undertaken mainly amongst UK practitioners. Quantitative research allows researchers to generate data on a problem or concept, from which insights and theory can be deduced (Bryman, 2008). Surveys provide data about the opinions and characteristics of a defined population ([Chisnall, 2001] and [Oppenheim, 1992]). The survey comprising 15 questions, framed from earlier research, was distributed in an online format (using SurveyMonkey) via email to the UK-based researcher's email network and through an internet URL on the UK PR industry e-newsletter, , in November and December 2010. This convenience sample was chosen as an aim of the study was to frame questions to be included in the annual European Communication Monitor (ECM) study. It comprised five closed questions and five open (write-in) questions, as well as questions on the demographics and work roles of the respondents. This research sought practitioner understanding of ROI with the aim of identifying current practices in public relations measurement of effectiveness, and insight into the language of public relations and corporate communications practice. As a snowball technique was applied through using the industry website, it is not possible to provide a level of response. The survey received 66 responses in a 4-week period before it was closed. Data were processed through SPSS for frequencies. The initial closed question was “do you regularly use the term ‘ROI’or ‘Return on Investment’when planning and evaluating PR activity?”Those who answered Yes were then asked “do you plan for a specific financial ROI outcome or is the ROI expressed in achievement of communication objectives”and asked to choose one option from “financialoutcome”, “communication outcome”and “other”. The latter was a write-in answer. Those who answered No, were directed to a later write-in question about the meaning of ROI. The following two questions asked for self-identification as “consultancy or freelance”or “in-house”and enquired separately about whom in their organisation either offered an ROI formula or applied it. Consultants and freelances were asked whether they offered clients an ROI formula or it was set by the client, whilst in-house practitioners (corporate, governmental and not-for-profit) indicated whether their employing organisation “had an ROI formula”. These questions sought indications of the use of the ROI concept and formulae amongst practitioners before discussing the notions of ROI. The final closed question was “Should there be a standard ROI adopted by the PR industry?”The open questions sought responses such as “please give a summary of the ROI formula(e) used by you or clients”(for both consultancy and in-house situations) and “what does ‘ROI’mean to you in the public relations context?”After being asked in a closed question whether they supported the concept of a standard ROI, respondents were asked to explain why they supported or rejected the concept. They were also asked to describe the ROI methods that were applied in practice.3. SampleThe sample was 55% female and 45% male. Their workplaces were 44% in-house, 44% consultancy, 12% freelance or other and they mainly held management roles with 42% identifying as a director, 39% manager and only 11% as executive. The residue was freelance or did not identify a role title. The sectors in which they worked were diverse with apreponderance of corporate (39%) followed by 22% product, 19% services, 16% government with the residue in not-for-profit or giving no answer. As could be expected from the researcher's UK base, 83% of the sample came from the UK of which 50% were from England (outside London), 27% London and 3% Scotland, with no responses from Northern Ireland or Wales. Some 17% of respondents identified themselves as coming from outside the UK, mainly Europe. Despite being a convenience sample, it does have validity as 55% of respondents which female, which aligns with the trend of increased female employment in UK public relations (CIPR, 2009). It is also strongly (81%) weighted towards management roles which should have indicated knowledge and use of ROI and effectiveness measures. It also has a strong presence in corporate and governmental sectors (55%) where longer-term communication planning is more evident than in products or services.4. ResultsAsked whether they regularly used the term ‘ROI’or ‘Return on Investment’when planning and evaluating public relations activity, there was a strongly positive response. Two-thirds (66.7%) answered in the affirmative and 33.3% in the negative. Those who answered ‘yes’, again gave a decisive response when asked which form of ROI outcome was used for evaluation, with 66.7% identifying ‘communication objectives’, followed by 19.0% for ‘other’and 14.3% for ‘financial outcome’. There were 12 write-in responses to describe ‘other’which were thematically grouped as “it depends on the campaign/client”(5), a combination of financial and communication objectives (4) and a ‘mix of inputs and outcomes’(efforts and results).ROI formulae were offered predominantly by consultancy and freelance respondents to clients (67.7%). Few clients, however, applied ROI judgements (12.9%). Some 19.4% did not apply any form of ROI. The methods offered, however, showed that advertising value equivalence (AVE) lives on an ROI form with six respondents using it including one who provided this formula: “PR spend to AVE = ROI”. Other methods were ‘negotiate measurements with client’(6), ‘meet media volume targets/media ranking’(3) and ‘relate press activity to outcomes, sales, and enquiries’(2). Most in-house practitioners reported that their organisation did not have an ROI formula (78.3%), with only 21.7% doing so. The methods used included an AVE-based formula (2), sales link to public relations activity, tonality of media coverage and a media ranking system.The first open question asked of all respondents was “what does ROI mean to you in the public relations context?”Using thematic coding (Schroder, 2002) of the 58 responses, the leading “meanings”were ‘demonstrate outcomes; show value of PR’(11) and ‘return on expenditure or effort’(9), which could be combined into a new theme of ‘demonstrable creation of value’. These were followed by forms of AVE (6), contribution to organisation's success (5), sales generated (5) and measurable financial gain (4). Both ‘contribution to organisation's success’and ‘measurable financial gain’might also be added to ‘demonstrable creation of value’, although ‘contribution to organisation's success’does not necessarily include financial outcomes and could be related to achievement of non-financial goals.The second open-ended question, “should there be a standard ROI adopted by the PR industry?”had been prompted by Metrica's 2004 research for the CIPR which raised thisprospect. The feedback from 61 respondents was a strong 64.5% rejection with 33.9% in favour and one no-answer. The written comments also give strong shape to that rejection with 32 arguing ‘one size does not fit all’and a closely aligned further three saying that ‘PR is not like business and finance’. The latter comment was also mentioned as a secondary factor in several ‘one size does not fit all’responses. Amongst the other rejection comments were “too much is measured already”and “it's a waste of time.”The case in favour of a standard ROI was composed of themes such as ‘yes, we need it but I don’t know what it will be’(7), there should be ‘broad or flexible parameters, coupled to best practice information’and a version of AVE (3).5. Discussion and conclusionThe use of the term, Return on Investment (ROI), is widespread in public relations practice. Although this study focused on the UK, it is a term is used in many public relations markets. Some two-thirds of those who took part in this short-term study claim to regularly use ROI, especially in relation to communication objectives. As the sample is made up of mid- and senior-level practitioners who mainly work in consultancies or in-house workplaces, with a strong emphasis to corporate and governmental sectors, it would be reasonably expected that they could (and should) be able to clearly express notions of ROI. This usage of ROI should be strategic and in relation to objectives and outcomes, yet the study gives evidence of mainly publicity-oriented tactical thinking and few respondents could demonstrate a process or methodology. It can be induced from the responses that many practitioners still conceive public relations as equated with media relations. The single most-mentioned ROI metric,although not dominant, was AVE and indicates the limitations in practice methods and lack of practitioner exposure to more robust research methodologies.6. Future researchThe survey responses to the open-ended questions offer guidance for future direction of development of theory and best practice on ROI. In addition to the intent of practitioners to use ROI, as evidenced by their claims to use it, the notions expressed in the ‘what it means’question leads discussion towards exploration of how ‘demonstrable creation of value’may be expressed especially in non-financial forms. It is also obvious that practitioners reject a single ROI formula (e.g. ‘no one size fits all’). So should ROI in public relations have a foundation in management theory in order to give it credibility and should future research explore a broader guidance on methods by judgement can be made on PR's contribution to organisational success? Watson (2008) found, in an international delphi study, that the two leading research priorities for public relations were: “Public relations’role in contributing to strategic decision-making, strategy development and realisation and organisational functioning”and “The value that public relations creates for organisations through building social capital; managing key relationships and realising organisational advantage”(p. 115). These priorities relate closely to ROI concepts in their references to the contribution of public relations to organisational efficiency and the creation of non-financial value. Along with the outcomes of this small sample survey, they will be the focus of future research amongst practitioners across Europe.。
2009年高考宁夏卷(理综生物 新课标卷)试题及各题答案详解

2009年普通高等学校招生全国统一考试(宁夏卷)理科综合能力测试(生物部分 含答案详解)一、选择题:每小题6分,在每小题给出的4个选项中,只有一项是符合题目要求的。
1. 下列关于动物细胞编程性死亡的叙述,正确的是A .细胞癌变属于细胞编程性死亡B. 细胞编程性死亡属于正常生理过程C .细胞编程性死亡属于细胞分化过程D .细胞编程性死亡与基因表达无关答案:B【解析】细胞编程性死亡是由基因所决定的细胞自动结束生命的过程,受到严格的由遗传机制决定的程序性调控,是一种正常的生理过程.而细胞癌变是由于原癌基因和抑癌基因发生突变,导致正常细胞的生长和分裂失控所致.因此,B 正确.2. 右图表示酶活性与温度的关系。
下列叙述正确的是A .当反应温度由t 2调到最适温度时,酶活性下降B .当反应温度由t 1调到最适温度时,酶活性上升C .酶活性在t 2时比t 1高,故t 2时更适合酶的保存D .酶活性在t 1时比t 2低,表明t 1时酶的空间结构破坏更严重答案:B【解析】在最适宜的温度下,酶的活性最高.温度偏高或偏低,酶活性都会明显降低. 当反应温度由t 2调到最适温度时,酶活性上升.温度过高,还会使酶的空间结构遭到破坏,使酶永久失活,0左右的低温虽然使酶的活性明显降低,但能使酶的空间结构保持稳定,在适宜的温度下酶的活性可以恢复,酶适于在低温下保存,故C,D 错误.3. 下列关于物质跨膜运输的叙述,错误..的是 A .植物细胞积累K + 需消耗能量B .细胞对离子的吸收具有选择性C .海水中的海藻细胞可通过积累溶质防止质壁分离D .液泡中积累大量离子,故液泡膜不具有选择透过性答案:D【解析】液泡膜是一层生物膜,具有选择透过性,能够积累大量的离子.细胞液的浓度小于外界溶液的浓度时,才可能发生质壁分离, 海水中的海藻细胞可通过积累溶质使细胞液的浓度增大防止质壁分离.4. 下列关于激素的叙述,错误..的是 A .肾上腺素发挥作用后被灭活B.体内失水过多时抗利尿激素释放减少C.激素调节过程中存在反馈调节D.对血样中相关激素水平的分析可帮助诊断甲状腺疾病答案:B【解析】抗利尿激素主要作用是提高肾小管和集合管对水的通透性,促进水的吸收. 所以体内失水过多时抗利尿激素释放增加.因此,B错误.5. 下列对于神经兴奋的叙述,错误..的是A.兴奋部位细胞膜两侧的电位表现为膜内为正、膜外为负 B.神经细胞兴奋时细胞膜对Na+ 通透性增大C.兴奋在反射弧中以神经冲动的方式双向传递D.细胞膜内外K+、Na+ 分布不均匀是神经纤维兴奋传导的基础答案:C【解析】神经细胞内K+浓度明显高于膜外,而NA+浓度比膜外低. 静息时,由于膜主要对K+有通透性,造成K+外流,电位表现内在外负, 受到刺激时,细胞膜对NA+的通透性增加, NA+内流,使兴奋部位膜内侧阳离子浓度高于膜外侧,表现内正外负. 兴奋在神经元之间的传递是单向的,故,C错误.6. 已知某闭花受粉植物高茎对矮茎为显性,红花对白花为显性,两对性状独立遗传。

【解析】天体的运动满足万有引力充当向心力即22Mm v G m R R=可知v =与地球绕太阳运行的线速度之比0.44v v ==≈木地,B 正确。
16. 医生做某些特殊手术时,利用电磁血流计来监测通过动脉的血流速度。
电磁血流计由一对电极a 和b 以及磁极N 和S构成,磁极间的磁场是均匀的。
使用时,两电极a 、b 均与血管壁接触,两触点的连线、磁场方向和血流速度方向两两垂直,如图所示。
由于血液中的正负离子随血流一起在磁场中运动,电极a 、b 之间会有微小电势差。
在达到平衡时,血管内部的电场可看作是匀强电场,血液中的离子所受的电场力和磁场力的合力为零。
在某次监测中,两触点的距离为 3.0mm ,血管壁的厚度可忽略,两触点间的电势差为160µV ,磁感应强度的大小为0.040T 。
则血流速度的近似值和电极a 、b 的正负为A. 1.3m/s ,a 正、b 负B. 2.7m/s , a 正、b 负C .1.3m/s ,a 负、b 正 D. 2.7m/s , a 负、b 正【答案】A 。

) Cloning is a radical challenge to the most fundamental laws of biology; so many people are concerned that it might be a preface to activities that will threaten human society and dignity.Conservative spiritual leaders have claimed that cloning a human constitutes a gross attack on human dignity. That would surely be true if a cloned individual were treated as a lesser being, with fewer rights or lower status. But why suppose that the laws that protect our rights and dignity would not be applicable to cloned person?Many of the vivid warnings of science fiction concerning the prospect of human cloning turn out, upon reflection, to be wildly improbable. There’s the fear, for instance, tha t parents might clone a child for the sake of having “surplus parts” in case the original child needs an organ transplant. But parents of identical twins don’t view one child as an organ farm for the other. Why should cloned children’s parents be any diffe rent?Another disturbing thought is that cloning will lead to efforts to breed individuals with genetic qualities perceived as desirable. Such ideas are offensive, not only because of an unthinking disgust, but also because of the horrors carried out by the Nazis in the name of improving their race. But there’s a vast difference between the breeding programs as practiced by some groups (where the urge to breed certain types of people leads to efforts to destroy other types) and the much more harmless forms already practiced in democratic societies (where, say, lawyers freely choose to have sexual relations with other lawyers). Banks stocked with the frozen sperm of geniuses already exist, but they haven’t created a master race because few women are queuing up to get pregnant this way. Why should we think it would be different if human cloning becomes available?Even if human cloning offers no obvious benefits to mankind, why ban it? If it might go any further, it should---and no doubt will---take place only under careful examination and layers of legal administration. Most important, human cloning should be governed by thesame laws that now protect human rights. A world that is not safe for cloned humans would be a world that is not safe for the rest of us.1. The writer thinks that cloning is a big challenge to the laws.2.3.4.5.6.7.8.9.10.Section Two: Passage Reading (10 points)Directions: In this section, there are two passages followed by some questions or incomplete sentences.You must choose the best one from the four suggested answers marked A, B, C and D. Thenmark the corresponding letter on the Answer Sheet (1) with a single line through the center.(答案做在答题纸(1)对应的题号上。
)Passage 1A study issued by the University of Washington shows that a lack of academic achievement is closely linked to substance abuse, violence and illegal behavior in the students’ social environment. According to the study, groups of middle and high school students with even moderate involvement with substance abuse, violence and illegal behavior have dramatically lower academic achievement than groups of students with little or no involvement in these behaviors. Factors such as poverty, community risk, absence of social skills, and a lack of commitment to school also contribute to lower academic performance among groups of students.The researcher said, “If we e xpect most students to achieve our state’s learning goals, we need prevention programs that target the social environment and that are extensive enough to reach all students in all schools. Our efforts should engage schools, parents and the community and focus on factors outside the classroom.” Dr. Sheri L. Hill, assistant di rector of the UW’s Washington Kids Court project, also said, “Intervention needs to start when students begin their first day of school and continue through high school.”The 2000 Washington State Survey of Adolescent Healthy Behaviors found that 20 to 40 percent of middle and high school students are involved with substance abuse, violence and illegal behavior. This means a significant proportion of children at age 10 and older are exposed to risky attitudes and behaviors in their everyday social environments.“We have to approach student learning from the perspective of the whole child,” said Terry Bergeson, state superintendent of public instruction. “We’ve known about the individual effects poverty, substance abuse and violence can have on young people. Today’s study takes that knowledge one step further by demonstrating their collective effect on the entire school community,” she added, “The way to influence student success includes strong schools, parental involvement and community participation. It must be a shared responsibility.”11. Lower academic achievement is closely linked to all of the following except ______.A. commitment to schoolB. absence of social skillsC. poverty and community riskD. violence and illegal behavior12.13.14.15.Passage 2When faced with death, we all react in different ways. Most people hope for a “good death”, however they may define it. There are many books which are available to help you approach death mindfully and plan for end-of-life care in a systematic way. If you are faced with making decisions about end-of-life care for yourself or someone you love, a good place to start is with the Handbook for Mortals, a caring and authoritative guide written by a team of experts in the field.It’s important fo r a person to express preferences about health care at the end of life. This can be done through the use of formal legal documents which grant a power of attorney for health care to someone you trust to make decisions for you should you become unable to do so yourself. These directives, which may be called living wills, must be tailored to your specific situation and location, as laws vary around the world. These directives may cover any issue you consider important. A very common concern centers around tube feeding and related issues including difficult decisions about withdrawing life-sustaining treatment.A very important decision is whether or not you wish to choose home or hospice care (临终关怀) as an alternative to a hospital setting. Whether at home or in a hospital, it’s important to demand top-quality palliative (缓和的) care. You can inform yourself about specific diseases by researching health care texts.Many faith traditions place emphasis on the importance of conscious preparation for death as a way of showing respect for and acceptance of life’s final adventure. Death is not the opposite of life—it is the opposite of birth.The decision to end one’s life when death is approaching anyway is sometimes called physician-assisted suicide (PAS), or voluntary euthanasia (安乐死); this is a special case of the more general topic of suicide. The “right to die” is the subject of controversial legal battles on an international scale.16. W hich of the following is true about the Handbook for Mortals?A. It giv es people a clear definition of a “good death”.B. It helps people to make decisions about end-of-life care only for someone they love.C. It is a caring and authoritative story written by experts.D. It helps people plan for end-of-life care systematically.17.18.19.20.Section Three: Reading in Depth (10 points)Directions: In this section, there is a passage with 10 blanks. You are to fill in the blanks by selecting suitable words from the Word Bank given below. Each choice in the Word Bank is identifiedby a letter. You may not use any of the words more than once.
