无论你是要毕业论文发表、还是要教育论文发表，在投稿的时候一定要搞清楚杂志的真伪，鉴于现在发表论文出现的供小于求的局面，很多杂志社只顾自己挣钱，完全不顾论文发表后作者是否能顺利评上职称，是否能顺利毕业，在各大论文发表网的推波助澜下，演绎了无数的问题刊物，增刊、一号双刊、副刊、假刊、论文集等等，广大作者在选择论文代发机构时一定要注意对作者利益的保障措施是否到位，永远别轻信他们的诚信口号。
英文护理科研论文的正文，一般由引言、材料和方法、结果及讨论4个部分构成。
(一)引言(Introduction)
引言是正文的第一个部分，它的作用是向读者介绍论文的研究背景，说明该研究课题国内
外的研究现状，取得的研究进展及尚待解决的问题，使读者大体了解选择本课题研究的理由和
意义，从而扼要地说明本项研究的目的、内容及价值等。因此，写好引言可使阅读者在文章的
开头就能大致了解论文的概貌、价值和意义，顺利引导读者进入论文的主体部分。引言一般采
用漏斗式结构(funnel structure)，即从叙述已知(known)的主题开始，转向该主题未知(un-
known)方面或存在的疑问句(question)，再提出该研究需要解决的问题(experimental ap-
proaeh)作为结束。在写作时应逐步深入主题，保证句子间有很强的连贯性，作好逻辑推导，要
精选用词，突出主题。在引言中可以围绕与本研究相关的工作进行适当的文献引用，但切忌滥
引。引言的结尾可以是对问题的陈述，回答所提出的问题，或引发的思考或期望。
在引言中，用动词的一般现在时表述真实的内容及未知内容；用一般过去时表述已发现的
内容及过去考虑过或做过的内容。对提出的问题应用一般现在时叙述，因为问题是客观真实
的而非仅为本实验的内容。
引言字数不可冗长，内容选择不宜过于分散、琐碎，措辞要精练，要吸引读者读下去。引言
的篇幅大小，需视整篇论文篇幅的大小及论文内容的需要来确定。
RECOMMENDATIONS To limit influenza outbreaks in nursing homes include vaccina-
tion,measures to limit exposure to infectious secretions’and the administration of antiviral
agents.In 1990,when this study was initiated，the Center for Disease Control(now the Cen-
ters for Disease Control and Prevention[CDC])recommended that to be fully effective as
prophylaxis’the antiviral drug must be taken each day for the duration of influenza ac-
tivity in the community.A conscientious clinician might continue chemoprophylaxis for the
duration of activity in the most localized reporting area，which might be as large as an entire
state．Community public health agencies have not had the responsibility to expeditiously in-
form nursing home practitioners when activity is over’and they cannot reliably predict
it．Recommendations for effectively administering antiviral chemoprophylaxis that include
limiting the duration，possible toxicity，expense,and the emergence of antiviral resistance
need to be clarified。The goal of this study was to investigate the optimal duration of antiviral
chemoprophylaxis using 2 protocols of differing durations．This work includes prospective
surveillance with viral culture of all consenting symptomatic nursing home residents and is
not directly comparable with most previously reported outbreaks that were identified retro-
spectively after dramatic,widespread clinical illness．More recently，the CDC recommended
that chemoprophylaxis in nursing homes should be continued for at least 2 weeks or until ap-
proximately 1 week after the end of the outbreak.Our experience supports this recommen-
dation．
