3、ew SummaryReview ObjectiveMany theories have been proposed to explain what motivates human behavior.Although the literature covers a wide variety of such theories,this review will focus on five major themes which emerge repeatedly throughout theliterature reviewed.These themes are:incorporation of t

12、 recognize the critical features to form an efficient and accurate algorithm to solve the numerical problems of FSI.()FTTTF Practice these patterns and expressions often used in writing a literature review.1.1 研究主题研究主题:一般现在时(多用),现在完成时,如:一般现在时(多用),现在完成时,如:1)Out-of-class language learning is defined a

13、s any language learning activities that are performed outside the class,be it for the sake of learning the language itself or for pure pleasure.2)The increasing popularity and wide availability of World Wide Web technologies provide the researcher with vehicles for improving research methods.3)It ca

14、n be argued that because of the diversity of sources of literature encompassed by the management disciplines,there is a growing need for a systematic methodology to map the territory of management theory.4)Service quality can be defined as a customers perception of the overall superiority of an orga

15、nizations excellence in providing service.5)The idea that institutions within the organic sector operate according to a decidedly different logic than do conventional agribusinesses can be situated within the century old“agrarian question”which attempts to understand how specific economic and ecolog

16、ical structures of agrarian production confound capitals penetration,defined as a wage labor at the site of production.6)To propose a relationship between language and the motor system is certainly not a novel idea.Theories about the gestural origin of language can be traced back to the writings in

17、the eighteenth century.7)With the increasing presence of policy networks and geographical and conceptual border crossing of policy elites,efforts to globalize educational institutions have meant that something of a common discourse has become apparent in educational policy.8)Since the latter part of

18、 the twentieth century,we are experiencing a duality:on the one hand the way policy is made is highly contextualized and its implementation even more context-dependent,on the other,policy travels globally,widespread and profound.1.2 研究意义研究意义:一般现在时、现在完成时,如:一般现在时、现在完成时,如:1)This very question has spark

19、ed debate between the scientific community and many conservationists.2)Actually,it seems that this concept would not lose its attractiveness in all fields yet and will be able to continue to attract many researchers in the next several years.3)Perhaps,more than ever before,because of these and other

20、 reform and policy movements,there is now an emerging clarity of thinking and consensus of thought about the nature of teaching and learning and the function and purpose of schools in this country.4)Maintaining this focus helps to ensure that social exclusion theories and policies do not fall solely

21、 back on deficit theories focused on the pathology of individual or groups of individuals.5)Learning Design provides a first glimpse at the ways of describing multi-learner activity sequences and the tools required to support these.6)The coherence found in teachers practices and beliefs has implicat

22、ions for teacher intervention programs.It suggested that efforts to change practices cannot be piecemeal and require attention to teachers basic beliefs about what is important.1.3 1.3 研究背景研究背景:多用一般过去时(常用被动语态),现在完成时,多用一般过去时(常用被动语态),现在完成时,一般现在时,如:一般现在时,如:1)Most of the sources I have used in my resear

23、ch have supported the idea of using cloning to rebuild animal populations or at least obtain viable DNA from endangered animals.2)Over the past several years,there have been a variety of debates in the literature in consideration of service quality conceptualization and measurement.3)After that thes

24、e authors developed an instrument called SERVQUAL that has been the most widely used tool in measuring customers perception of service quality.4)Numerous researches conducted the five dimension model in different sectors in different countries that some researches confirmed the five dimension model

25、but some others failed.5)By undertaking an SLR approach rather than“ad hoc”approaches to literature construction,development and presentation,there is a defense that critical literature may be identified alongside other materials relevant to the study.6)The new agrarian literature has elaborated on

26、De Janvrys presentation of the classics by analyzing reality as a continual process taking place on multiple levels of society and place,and incorporating a sophisticated understanding of power into theorizations of agrarian histories.7)The proposed research is situated at the intersection of three

27、bodies of literature:theories of“global economic restructuring,”with specific attention to rural restructuring;the history and historiography of Western regional development and underdevelopment;and studies of environmental politics,particularly those taking the form of social movements.8)It is equa

28、lly important to consider the persistence of non-capitalist enterprises as a result of their own structural logic and their ability to out-compete capital.While this thread originate with Chayanov,Friedmann extends the Chayanovian argument to show that even where production is both competitive and s

29、pecialized,simple commodity producers may out-compete enterprises based on hired labor.1.4 导致研究问题的相互矛盾的研究结果导致研究问题的相互矛盾的研究结果:一般现在时、一般现在时、现在完成时,一般过去时,如:现在完成时,一般过去时,如:1)Although,a lot of studies have been examined and practiced SERVQUAL model as a framework in measuring service quality,there has also b

30、een extensive criticism directed towards this measure in the marketing literature.2)Although many reports and studies are conducted for and on behalf of the civil service and its associated executive bodies,they are often confined to looking at specific issues,policies or implementations.3)Clearly,t

31、here are still discrepancies in literacy standards between countries and between genders in some countries.4)This analysis has much to recommend it,but serious flaws as well.5)Most of the agrarian transitions literature has nevertheless focused on the social relations of production,and not the uniqu

32、eness of land-based production.6)However an approach which focuses solely on the improvement of average school performance is likely to be a less effective means of reducing social exclusion than an approach which creates incentives that rewards improvement among the least able.7)However,there is li

33、ttle understanding of how to create sequences of learning activities which involve groups of learners interacting within a structured set of collaborative environments,or how teachers can make these sequences easily re-usable.8)Much of the literature on educational change tends to focus on schools a

34、s contexts for change.While some of this work has little relevance for early childhood educators,other aspects provide useful opportunities for reflection.1.5 研究问题研究问题:一般现在时,现在完成时,如:一般现在时,现在完成时,如:1)The question I ask now is this:Will cloning be used in the conservation of endangered species?2)Though

35、 these theories are focused on the organizational effectiveness from different perspectives:the classical perspective,neoclassic perspective and environmental perspective,I argue that these concepts are supplementary rather than contentions.3)These studies have,however,suffered a major shortcoming:l

36、inguistic material,which consisted most often of elaborated sentences,and experimental designs used did not allow one to address the issue of what makes the simulation situated.4)In fact,no scale currently exists to assess rent-a-car quality in the tourism industry as a whole.5)Contrary to the value

37、s set forth by many conservationist groups,my research suggests that the cloning of endangered species is,in fact,a viable option in their preservation and repopulation.6)I argue that each individual organizational theory is packed with dents,and every one of them is propping against the other conce

38、pts.7)The study of knowledge has always been controversial throughout the history of philosophy and science,leading to a lack of clarity and numerous positions along a continuum with two extremes:knowledge is ascribed a purely objective or a purely subjective existence.8)The extent to which organic

39、producers withstand or incorporate processes of appropriation,specifically,will be a focal point of this study.1.6 研究目的研究目的:一般现在时,一般将来时,如:一般现在时,一般将来时,如:1)As my research suggests,cloning endangered species will surely have its benefits in keeping these populations alive,an option which conservationis

40、ts cannot deny.2)To date,relatively little is known about car rental business of the tourism industry,including how it may influence the tourism and hospitality industry.This study aims to fill this gap in the relevant literature.3)In echoing to this,the current study attempts to develop a new multi

41、-item measurement scale for assessing the perceived quality in car rental services.4)The lack of Web Survey literature that study the effect of social and methodological factors in these societies on the quality of Web Survey results are main reasons to conduct the current study.5)An adequate explan

42、ation of it must therefore move beyond such simplistic functionalism to explore how and why the particular configurations of Wise Use have emerged,contributing to current work on the significance of geographic variations in responses to international restructuring.6)The purpose of this study,which w

43、ill be the first of its kind,is to examine the genesis,development and character of the California organic produce sector to demonstrate how a particular notion of“organic”has been constituted politically,and how this codified definition shapes the structure and geography of the sector.7)Our finding

44、s are in keeping with embodied approaches to language understanding and suggest that the language sensorimotor specificity of sentence constituents affects the extent to which the simulation is situated.8)This chapter,for the first time in the English literature,investigates how education policy is

45、researched in Mainland China.It attempts to understand how Chinese education policy researchers are influenced by external forces while struggling with their local relevance.The aim of a literature review is to show your reader(your tutor)that you have read,and have a good grasp of the main publishe

46、d work concerning a particular topic or question in your field.It is very important to note that your review should not be simply a description of what others have published in the form of a set of summaries,but should take the form of a critical discussion,showing insight and an awareness of differ

47、ing arguments,theories and approaches.It should be a synthesis and analysis of the relevant published work,linked at all times to your own purpose and rationale.The literature review should:Compare and contrast different authors views on an issue;Group authors who draw similar conclusions;Criticize

48、aspects of methodology;Note areas in which authors are in disagreement;Highlight exemplary studies;Highlight gaps in research;Show how your study relates to previous studies;Show how your study relates to the literature in general;Conclude by summarizing what the literature says;The purposes of the

49、review are:To define and limit the problem you are working on;To place your study in a historical perspective;To avoid unnecessary duplication;To evaluate promising research methods;To relate your findings to previous knowledge and suggest further research.A good literature review,therefore,is criti

50、cal of what has been written,identifies areas of controversy,raises questions and identifies areas which need further research.1.Complete the following sentences by translating Chinese into English.Task Realization1)One-gun-a-month rules significantly reduce the number of gun shows.1)It has merely i
