China's transgenic technology started earlier, China's current GM technology level in the forefront of the world, especially made great achievements in the cultivation of new varieties of crops. In this paper, the status quo using gene transfer on Chinese agriculture and safety of transgenic technology are introduced, and the resolve of GM safety issues some thought. On this basis, I made some new ideas of transgenic technology and application of transgenic technology development prospects were discussed.Keywords: GM technology; GM crops; GM safety issues; ChinaIntroduction:As the core of the biotechnology giant leap .Transgenic technology is known as the second "green revolution." In 1983, the world's first strain of transgenic tobacco plants marks the arrival of the era of gene transfer plants. In the ensuing decades, genetically modified crops developed rapidly. In 2014, there are 28 countries in the world planted GM crops, the planting area has reached more than 180 million hectares, Chinese genetically modified crops planting area is 3.6 million hectares. With the widespread planting of genetically modified crops, the impact of transgenic technology in agriculture is growing. As the research of GM crops, China has made great achievements in the research of rice and cotton.The development of anything will not be smooth. With the development of GM technology, its security deposit issues also be exposed. The safety of genetically modified crops has been disputed by people, opponents argue that GM crops have great potential risk, it should be resisted. What is more, some people exaggerate the risk of genetically modified crops. Aroused people's fear of genetically modified. In this paper, the people of GM crops concerns, the status of the development of GM crops were elaborated. Besides, security problems of genetically modified crops and their solutions will be discussed.The current development of genetically modified crops in chinaGM refers to the Technology that use molecular biology method to transfer the artificial separation and some modified biological gene to other species and change the genetic characteristics of the species .Plant transgenic technology is the genetic transformation of plants, making plants to meet human needs in aspects of shape, nutrition and consumer quality.China's biotech crop improvement research began in the 1980s, during the past 30 years, Chinese agricultural and biological high-tech has been developing rapidly. At present, China's hybrid rice, cotton and other advanced in the world. GM technology Applied on cotton, rice and other crops on behalf of China's development status of GM crops.As a cotton producing countries, the industrialization of Chinese insect-resistant cotton has brought huge economic and ecological benefits to Chinesesociety. Since the 1990 s, China's major cotton producing areas often suffered insect outbreaks and the effect conventional control is poor. In 1994, under the impetus of the country, Bt gene was successfully imported into The main plant cotton species .China has become the second country with the independent development of insect-resistant cotton.In 1999, China began to commercial cultivation of cotton. In 2010, gm cotton planting and product in China reached 3.45 million hectares, accounting for 69% of the total cotton planting and product. The planting of insect-resistant cotton have effectively controlled the damage caused by the cotton bollworm .The insect-resistant cotton also reduced pesticide use, protect the farmland ecological environment.Cotton yield and growth of calendar year in China:China's research on genetically modified (gm) rice have got rich achievements. In August 17, 2009, the Ministry of Agriculture promulgated transgenic rice security certificate for the two anti-lepidopteran pests transgenic rice -----"Hua Hui 1" and "Bt Shan You 63" .In addition, China has produced the anti-amino phosphonic herbicide Bar gene rice lines, the new salt tolerance strains which represented by T22-77. Compared with ordinary rice, these transgenic rice has unmatched superior properties .It will bring huge economic benefits to Chinese farmers if these rice be planted on large-scale .For example, each 667m2 planting salt-tolerant transgenic rice can increase the income of 100 yuan. Transgenic rice can reduce the use of pesticides and fertilizers, which is benefical to the environment.GM soy is the world's first commercialization, promotion and application of the fastest growing GM crops .Dates from Agropages shows that show in 2012 , global soybean acreage reached 107 million hectares, of which GM soybeans accounted for 79 percent (84.5 million hectares). As the world's first four major soybean producing countries, China is planting soybeans which are non-GMO soybeans. The transgenic soybean was still in the research stage, failed to achieve commercial GM soy production and large-scale demonstration.Analysis about safety issuesGM technology could efficiently improve crop yield, quality and resistance to meet growing human material needs. Transgenic technology is a double-edged sword, both its positive and beneficial side, also has its negative, the negative side, The biggest potential hazards of transgenic technology is the escape of target gene and gene pollution. With the genetically modified plants wide spread around the world ,the gene of interest may vary pollen spread to other species, or spread into the environment, which may causing unpredictable results. Canada's "superweeds" event and Mexican’s “corn genetic pollution” incident has sounded the alarm for us. Besides, certain genetic traits like instability of some transgenic plants are instability, transge nic plants’ good traits will become weaken over time. Another possibility is that some transgenic plants will produce some harmful variations which will endanger human health.Effects of transgenic expression products on humans is a problem that people are most concerned about. Some of the transgene expression product will make people allergic to. But for the most expression product we are lack of direct evidence to affirm their effects on human health and the environment.In order to verify the impact of Bt proteins on animal health. Since 1999, scientists feed white mouse with genetically modified food which containing the Bt protein for many years, the results showed that mice genetically modified agricultural products containing Bt protein is safe to the mouse. However, in the short-term animal feeding trials data can not prove the Bt protein is safe to us.Because human is the long-term consumer of rice. Recently, Canadian scientists discovered, Bt proteins can enter any place of the body. Even the in baby's umbilical cord blood were also found the Bt proteins. Therefore, this discovery had to let the people worried about the safety of transgenic Bt crops.Since the transgenic technology used gene beyond the conventional sexual hybridization gene scope, and for the problem that whether transgenic plants will affect human health and the environment or not we are also lack of systematic knowledge and experience .By the current level of science ,we can not be completely accurate prediction of the results of an outer genes in the new genetic background would cause.Currently, the safety evaluation of transgenic plants primarily relates to environmental safety and food safety aspects. The core issue of environmental safety assessment is after transgenic plants released into the field, whether it will evolve into weed, whether the genes will transfer to wild plants drift or not ; whether it will destroy the natural environment and break the original biological populations homeostasis ; whether it will destroy biodiversity, and so on. Ecological effects of GM crops may arise mainly in the gene flow, non-target effects, the target pest resistance evolution, etc.ConlusionFor security issues, by taking the right measures and scientific management system is able to solve these problems. We can improve the safety of transgenic plants from the following aspects:(1) Carrying out propagandas about genetically modified technical and transgenic plants.Cultivating people’s objectivity awareness of security issues to genetically modified(2) Improving the legal system transfer plant genes and their products;(3) The establishment of transgenic crop management technology system and risk assessment system; and(4) Using food processing technology to process raw materials of transgenic food, remove the transgene expression product that exist in the raw materials of transgenic food.In addition to cultivation of crops, we can also use transgenic technology to cultivate some asexual reproduction and non-food plants. This concept have two advantages .On the one hand, it is a good solution to the genes escape and genes pollution problems. Because the escape and contamination of genes mainly through plants’ pollen s, and asexual reproduction plants will not produce pollen. On the other hand, people do not worry about the transgene expression products will affect human health, because these transgenic plants is not food crops. Transgene expression products don’t enters the body. For example, we can cultivate forestry trees which with high resistance; foliage plants which can glowing; Aquatics which can absorb the harmful heavy metals in water and so on. These plants will bring great benefits to humanity. Prospects of transgenic technology is unlimited, as long as strengthen supervision and follow scientific methods, can be avoided completely turn the negative effects of human gene technology may bring.Reference:[1] Deng Xu, Wei Bin, Hu Zhang Li.

文献综述写法英文版
Finding, formulating and exploring your topic.Different topic creationsMany students have in mind something that they want to work on; others want to work with a particular scholar or research centre. In the first case, students search for a compatible supervisor. In the second, for a topic. Regardless of these preliminary circumstances, the topic is very likely only roughly formulated at this stage. This is usually enough to have your enrolment accepted. Reading the literatureOnce you have a general idea, you could start by talking to your supervisor and other scholars. But, most importantly, you have to think why you would like to work on it, or why anyone would want to do so. Ask yourself, "Why is it important? What is interesting about this? Suppose I solve it, or find it, or pull it all together, what use is it? What is its significance?" Then, with some questions such as these in mind, go and read more about it to see what is there and find out what aspects of it have been exhausted, what neglected, what the main ideas, issues and controversies are in the area. It is regarded as your supervisor's role to direct you to the most fruitful starting point in reading and surveying the literature.Cycle of literature reviewAll of this is not a once only activity, but is a cycle you go through again and again. So you read, think, and discuss it with your supervisor and then, as a result, come closer to the formulation of the topic. And then with each cycle of reading, thinking and discussing your topic becomes more specific and focused.This is not the final formulation and the last time you will focus your topic. But you could probably let go of this round of general exploration and embark on the next stage. Your supervisor by this time should have enough of an idea of your topic to judge whether or not what you propose to do is feasible within the time available and has the potential to meet the required standards for a PhD. To see the full potential of your topic or, to the contrary, see that it is not going to deliver what you wanted, you do need to begin doing your research. This, of course, is why pilot studies are often undertaken.Making sense of the literatureWe do truly wish we could tell you about a reliable or simple way to make sense of the literature. We can say, however, that you need to attend to things attwo levels:∙One is establishing a system that will allow you to organise the hard copies of the articles etc., and develop a data base for references, soyou have easy access under relevant categories and don't chase the samereferences repeatedly.∙The other is the more demanding task of understanding and using the literature for your purposes.Without attending to the first task, you could easily become inefficient and frustrated. However, although it is necessary to have some way of keeping track, don't spend all your energies on perfecting your system. It may be a good idea to attend a course for researchers on handling information. Check whether your university's library or computer centre offers such a course.The other task ahead of you - of understanding, reviewing and using theliterature for your purposes - goes to the heart of your thesis. We considerthis in three stages.Making sense of the literature - first passWhen you first come to an area of research, you are filling in the backgroundin a general way, getting a feel for the whole area, an idea of its scope,starting to appreciate the controversies, to see the high points, and to become more familiar with the major players. You need a starting point. This may come out of previous work you've done. If you're new to the area, your supervisor could suggest fruitful starting points. Or you could pursue some recent review articles to begin.Too much to handleAt this stage there seems to be masses of literature relevant to your research. Or you may worry that there seems to be hardly anything. As you read, think about and discuss articles and isolate the issues you're more interested in. In this way, you focus your topic more and more. The more you can close in on what your research question actually is, the more you will be able to have a basisfor selecting the relevant areas of the literature. This is the only way to bring it down to a manageable size.Very little thereIf initially you can't seem to find much at all on your research area - and you are sure that you've exploited all avenues for searching that the library can present you with - then there are a few possibilities:∙You could be right at the cutting edge of something new and it's not surprising there's little around.∙You could be limiting yourself to too narrow an area and not appreciating that relevant material could be just around the corner in a closely related field.∙Unfortunately there's another possibility and this is that there's nothing in the literature because it is not a worthwhile area ofresearch. In this case, you need to look closely with your supervisor at what it is you plan to do.Quality of the LiteratureThis begins your first step in making sense of the literature. You are not necessarily closely evaluating it now; you are mostly learning through it. But, sometimes at this stage students do ask us how they can judge the quality ofthe literature they're reading, as they're not experts.You learn to judge, evaluate, and look critically at the literature by judging, evaluating and looking critically at it. That is, you learn to do so by practising. There is no quick recipe for doing this but there are somequestions you could find useful and, with practice, you will develop many others:∙Is the problem clearly spelled out?∙Are the results presented new?∙Was the research influential in that others picked up the threads and pursued them?∙How large a sample was used?∙How convincing is the argument made?∙How were the results analysed?∙What perspective are they coming from?∙Are the generalisations justified by the evidence on which they are made?∙What is the significance of this research?∙What are the assumptions behind the research?∙Is the methodology well justified as the most appropriate to study the problem?∙Is the theoretical basis transparent?In critically evaluating, you are looking for the strengths of certain studies and the significance and contributions made by researchers. You are also looking for limitations, flaws and weaknesses of particular studies, or of whole lines of enquiry.Indeed, if you take this critical approach to looking at previous research in your field, your final literature review will not be a compilation of summaries but an evaluation. It will then reflect your capacity for critical analysis.Making sense of the literature - second passYou continue the process of making sense of the literature by gaining more expertise which allows you to become more confident, and by being much more focused on your specific research.You're still reading and perhaps needing to re-read some of the literature.You're thinking about it as you are doing your experiments, conducting your studies, analysing texts or other data. You are able to talk about it easily and discuss it. In other words, it's becoming part of you.At a deeper level than before,∙you are now not only looking at findings but are looking at how others have arrived at their findings;∙you're looking at what assumptions are leading to the way something is investigated;∙you're looking for genuine differences in theories as opposed to semantic differences;∙you also are gaining an understanding of why the field developed in the way it did;∙you have a sense for where it might be going.First of all you probably thought something like, "I just have to get a handle on this". But now you see that this 'handle' which you discovered for yourself turns out to be the key to what is important. You are very likely getting to this level of understanding by taking things to pieces and putting them back together.For example, you may need to set up alongside one another four or five different definitions of the same concept, versions of the same theory, or different theories proposed to account for the same phenomenon. You may need to unpack them thoroughly, even at the very basic level of what is the implied understanding of key words (for example 'concept', 'model', 'principles' etc.), before you can confidently compare them, which you need to do before synthesis is possible.Or, for example, you may be trying to sort through specific discoveries which have been variously and concurrently described by different researchers in different countries. You need to ask questions such as whether they are the same discoveries being given different names or, if they are not the same,whether they are related. In other words, you may need to embark on very detailed analyses of parts of the literature while maintaining the general picture.Making sense of the literature - final passYou make sense of the literature finally when you are looking back to place your own research within the field. At the final pass, you really see how your research has grown out of previous work. So now you may be able to identify points or issues that lead directly to your research. You may see points whose significance didn't strike you at first but which now you can highlight. Or you may realise that some aspect of your research has incidentally provided evidence to lend weight to one view of a controversy. Having finished your own research, you are now much better equipped to evaluate previous research in your field.From this point when you have finished your own research and you look back and fill in the picture, it is not only that you understand the literature and can handle it better, but you could also see how it motivates your own research. When you conceptualise the literature in this way, it becomes an integral part of your research.Writing the literature reviewWhat we are talking about here is the writing of the review. We assume that you have made sense of the literature, and that you know the role of the literature and its place in your thesis. Below are links to other sections covering these aspects.You will doubtless write your literature review several times. Since each version will serve a different purpose, you should not think you are writing the same thing over and over and getting nowhere. Where you may strike trouble is if you just try to take whole sections out of an earlier version and paste them into the final version which, by now, has to be differently conceived.In practical terms, it is necessary to have an overall picture of how the thread runs through your analysis of the literature before you can get down to actually writing a particular section. The strategy which writers use as a way to begin the literature review is to proceed from the general, wider view of the research you are reviewing to the specific problem. This is not a formula but is a common pattern and may be worth trying.Let's look at an example taken from the first pages of a literature review. This shows us the progression from general to specific and the beginning of that thread which then continues through the text leading to the aims.[This is basically an introductory section, which starts with astatement of the problem in very broad terms, alerting us to the factthat not everything is rosy, and proceeds to sketch in specific aspects.][The text moves on to specify issues at various levels. Although the[Thus the text has set up the situation where all aspects of theproblem--theoretical, practical, etc.--are brought together.]Whatever the pattern which fits your work best, you need to keep in mind that what you are doing is writing about what was done before. But, you are not simply reporting on previous research. You have to write about it in terms of how well it was done and what it achieved. This has to be organised and presented in such a way that it inevitably leads to what you want to do and shows it is worth doing. You are setting up the stage for your work.demonstrates neither your understanding of the literature nor your ability to evaluate other people's work.Maybe at an earlier stage, or in your first version of your literature review, you needed a summary of who did what. But in your final version, you have to show that you've thought about it, can synthesise the work and can succinctly pass judgement on the relative merits of research conducted in your field. So,Approaching it in this way forces you to make judgements and, furthermore, to distinguish your thoughts from assessments made by others. It is this whole process of revealing limitations or recognising the possibility of taking research further which allows you to formulate and justify your aims.Keep your research focusedIt is always important to keep your research focused, but this is especially so at two points. First when you have settled into the topic and the time forwider exploration has to end. And then again at a later stage when you may have gathered lots of data and are starting to wonder how you are going to deal with it all.Focus after literature reviewFirst, it is a common temptation to prolong the exploration phase by finding more and more interesting things and straying away from what was once regarded as the possible focus. Either you or your supervisor could be guilty of this.In some cases, it might be you who is putting off having to make a commitmentto one line of enquiry because exploration and realising possibilities is enjoyable and you're always learning more. In other cases, it could be your supervisor who, at every meeting, becomes enthusiastic about otherpossibilities and keeps on suggesting alternatives. You might not be sure ifthis is just sharing excitement with you or if you are supposed to follow them all up.Either way you need to stop the proliferation of lines of enquiry, sift through what you have, settle on one area, and keep that focus before you. It could even be a good idea to write it up on a poster in front of your desk. Unlessyou have this really specified in the first place, with the major question and its sub-questions, and you know exactly what you have to find out to answer these, you will never be focused and everything you find will seem to be 'sort of' relevant.You have to close off some lines of enquiry and you can do so only once you decide they are not relevant to your question. We continually meet students who, when we ask, "So what is the question you're researching?", will answer, "My topic is such and such and I'm going to look at x, y and z". Sometimes further probing from us will reveal that they do indeed have a focus, but many timesthis is not so. Thinking in terms of your topic is too broad. You need to think,Focus after data collectionThen, at a later stage, you could find yourself surrounded by lots of datawhich you know are somewhat relevant to your project, but finding the ways of showing this relevance and using the data to answer your question could be a difficult task. Now you have to re-find your focus to bring it all together.Again, it is your research question and sub-questions which will help youto do this because your whole thesis is basically the answer to these questions, that is, the solution to the problem you presented at the beginning. This may strike you as a very simplistic way to view it. However, approaching it in this way does help to bring the parts together as a whole and get the whole to work. We even recommend that, to relate the parts to each other and keep yourself focussed , you could tell yourself the story of the thesis.Making a deliberate attempt to keep focused will help you to shape your research and keep you motivated.Apparently I have to write a research proposal. What do I need to do? The main purpose of a research proposal is to show that the problem you propose to investigate is significant enough to warrant the investigation, the method you plan to use is suitable and feasible, and the results are likely to prove fruitful and will make an original contribution. In short, what you are answering is 'will it work?'The level of sophistication or amount of detail included in your proposal will depend on the stage you are at with your PhD and the requirements of your department and University.∙In initial stages, the document you need to write will probably be three to five pages long. It will give a general idea of what you areproposing to do but it isn't a binding contract. Often it serves as astarting point for discussions with your supervisor to firm up the topic, methodology and mechanics of your research.∙Some of you will be required to write a proposal at the time of confirming your candidature (usually at the end of the first year). Insome instances, this is a document of four to five pages and may beviewed as a mere formality. In other cases a much more substantialdocument of 30 - 40 pages is expected. Therefore it is essential for you to check the requirements with your department.Regardless of the above distinctions you should never see writing a proposal as a worthless chore. Indeed, if it isn't formally required, it is a very good idea to write one anyway. You can use it to your advantage. It always forces you to think about your topic, to see the scope of your research, and to review the suitability of your methodology. Having something in writing also gives an opportunity to your supervisor to judge the feasibility of the project (whether it is possible to finish in time, costs, the equipment needed and other practicalities, time needed for supervision), to assess its likelihood of success, and its ability to meet the academic standard required of a PhD thesis.While there are no hard and fast rules governing the structure of a proposal, a typical one would include: aims and objectives, significance, review of previous research in the area showing the need for conducting the proposed research, proposed methods, expected outcomes and their importance. In experimentally based research it often includes detailed requirements for equipment, materials, field trips, technical assistance and an estimation of the costs. It could also include an approximate time by which each stage is to be completed.write a abstract. Indeed, the final version of the abstract will need to be written after you have finished reading your thesis for the last time.However, if you think about what it has to contain, you realise that the abstract is really a mini thesis. Both have to answer the following specific questions:Therefore, an abstract written at different stages of your work will help you to carry a short version of your thesis in your head. This will focus your thinking on what it is you are really doing , help you to see the relevance of what you are currently working on within the bigger picture, and help to keep the links which will eventually unify your thesis.ProcessThe actual process of writing an abstract will force you to justify and clearly state your aims, to show how your methodology fits the aims, to highlight the major findings and to determine the significance of what you have done. The beauty of it is that you can talk about this in very short paragraphs and seeif the whole works. But when you do all of these things in separate chapters you can easily lose the thread or not make it explicit enough.If you have trouble writing an abstract at these different stages, then this could show that the parts with which you are having a problem are not well conceptualised yet.We often hear that writing an abstract can't be done until the results are known and analysed. But the point we are stressing is that it is a working tool that will help to get you there.Before you know what you've found, you have to have some expectation of what you are going to find as this expectation is part of what is leading you to investigate the problem. In writing your abstract at different stages, any part you haven't done you could word as a prediction. For example, at one stage you could write, "The analysis is expected to show that …". Then, at the next stage, you would be able to write "The analysis showed that …." or "Contrary to expectation, the analysis showed that …..".The final, finished abstract has to be as good as you can make it. It is the first thing your reader will turn to and therefore controls what the first impression of your work will be. The abstract has∙to be short-no more than about 700 words;∙to say what was done and why, how it was done, the major things that were found, and what is the significance of the findings (rememberingthat the thesis could have contributed to methodology and theory aswell).In short, the abstract has to be able to stand alone and be understood separately from the thesis itself.Is there a particular thesis structure I have to follow? There are certain conventions specific to certain disciplines. However, these structures are not imposed on a piece of work. There are logical reasons why there is a conventional way of structuring the thesis, which is after all the account of what you've achieved through your research. Research is of course not conducted in the step-by-step way this structure suggests, but it gives the reader the most accessible way of seeing why this research was done, how it was done and, most importantly, what has been achieved. If you put side by side all the questions you had to answer to finish your research and what is often proposed as a typical structure of a thesis, then you see the logic of the arrangement. That does not mean, however, that you have to name your chaptersin this way. In some disciplines, it very often is like this; in others, this structure is implied. For example, in many science theses, the following basically is the structure; in many humanities theses, the final structure looks very different, although all of these questions are answered one way or another.Occasionally a thesis is written which does not in any way comply with this structure. Generally the reasons you want to have a recognised, transparent structure are that, to some extent, it is expected and the conventional structure allows readers ready access to the information. If, however, you wantto publish a book based on the thesis, it is likely the structure would need to be altered for the different genre and audience.。

英语口语文献综述范文模板大全1. IntroductionIn recent years, there has been a growing interest in the field of English oral communication skills among researchers and educators. The ability to effectively communicate in English is essential in today's globalized world, and oral communication is a key component of this skill. In this literature review, we will examine the current research on English oral communication skills and explore the various factors that influence the development of these skills.2. Importance of English Oral Communication SkillsEnglish oral communication skills are crucial for success in both academic and professional settings. Effective oral communication allows individuals to express their ideas, thoughts, and emotions clearly and accurately. It also enables individuals to engage in meaningful conversations, debates, and discussions with others. Additionally, good oral communication skills are essentialfor building relationships, collaborating with others, and resolving conflicts.3. Factors Influencing English Oral Communication SkillsThere are various factors that can influence the development of English oral communication skills. These factors include individual characteristics (such as motivation, self-confidence, and language proficiency), social factors (such as cultural norms and communication styles), and contextual factors (such as the learning environment and teaching methods). Researchers have found that a combination of these factors can significantly impact an individual's ability to communicate effectively in English.4. Strategies for Improving English Oral Communication SkillsThere are several strategies that can help individuals improve their English oral communication skills. These strategies include practicing speaking regularly, engaging in conversations with native speakers, listening to English audio materials, watching English videos, and participating in language exchange programs. Additionally, takinglanguage courses, attending workshops, and receiving feedback from peers and teachers can also be beneficial in enhancing oral communication skills.5.

II. The purposes of literature review And Its ComponentsA. The PurposesOn the one hand, it helps you broaden the view and perspective of the topic for your graduation thesis.On the other hand, it helps you narrow down the topic and arrive at a focusedresearch question.B. Its ComponentsThere are six parts in a complete Literature Review.标题与作者(title and author)摘要与关键词(abstract and key words)引言(introduction)述评(review)结论(conclusion)参考文献(references)III. Classification of Source MaterialsHow can we locate the materials relevant to our topics betterand faster? Basically, all these source materials may be classified into four majors of sources.A: Background sources:Basic information which can usually be found in dictionaries andencyclopedia complied by major scholars or founders of the field. Three very good and commonly recommenced encyclopedias are encyclopedias ABC, namely, Encyclopedia Americana, Encyclopedia Britannica, and Collier’s Encyclopedia. There are also reference works more specialized, such as The Encyclopedia of Language and Linguistics for linguistics and TEFL studies. Moreover, you may also find Encyclopedia on the web.B: Primary sourcesThose providing direct evidence, such as works of scholars of the field,biographies or autobiographies, memoirs, speeches, lectures, diaries, collection of letters, interviews, case studies, approaches, etc. Primary sources come in various shapes and sizes, and often you have to do a little bit of research about the source to make sure you have correctly identified it. When a first search yields too few results, try searching by broader topic; when a search yields toomany results, refine your search by narrowing down your search.C: Secondary sourcesThose providing indirect evidence, such as research articles or papers, bookreviews, assays, journal articles by experts in a given field, studies on authors orwriters and their works, etc. Secondary sources will informmost of your writingin college. You will often be asked to research your topic using primary sources,but secondary sources will tell you which primary sources you should use andwill help you interpret those primary sources. T o use theme well, however, youneed to think critically them. There are two parts of a source that you need toanalyze: the text itself and the argument within the text.D: Web sourcesThe sources or information from websites. Web serves as an excellentresource for your materials. However, you need to select and evaluate Websources with special care for very often Web sources lack quality control. Youmay start with search engines, such as Google, Yahoo, Ask, Excit e, etc. It’s agood idea to try more than one search engine, since each locates sources in itsown way. When using websites for information, be sure to take care for theauthorship and sponsorship. If they are both unclear, be critical when you useinformation. The currency of website information should also be taken intoaccount. Don’t use too out information dated for your purpose.IV. Major strategies of Selecting Materials for literaturereviewA. Choosing primary sources rather than secondary sourcesIf you have two sources, one of them summarizing or explaining a work andthe other the work itself, choose the work itself. Never attempt to write a paperon a topic without reading the original source.B. Choosing sources that give a variety of viewpoints on your thesisRemember that good argument essays take into account counter arguments.Do not reject a source because it makes an argument against you thesis.C. Choosing sources that cover the topic in depthProbably most books on Communicative Language Teaching mention WilliamLittlewood, but if this your topic, you will find that few sources cover the topicin depth. Choose those.D. Choosing sources written by acknowledged expertsIf you have a choice between an article written by a freelance journalist onTask-based Teaching and one written by a recognized expert like David Nunan,Choose the article by the expert.E. Choosing the most current sourcesIf your topic involves a current issue or social problem or development in ascientific field, it is essential to find the latest possible information. If all thebooks on these topics are rather old, you probably need to look for information inperiodicals.V. Writing a literature ReviewA. When you review related literature, the major review focuses should be:1. The prevailing and current theories which underlie the research problem.2. The main controversies about the issue, and about the problem.3. The major findings in the area, by whom and when.4. The studies which can be considered the better ones, and why.5. Description of the types of research studies which can provide the basis for the current theories and controversies.6. Criticism of the work in the area.B. When you write literature review, the two principles to follow are:1. Review the sources that are most relevant to your to your thesis.2. Describe or write your review as clear and objective as you can.C. Some tips for writing the review:1. Define key terms or concepts clearly and relevant to your topic.2. Discuss the least-related references to your question first and the mostrelated references last.3. Conclude your review with a brief summary.4. Start writing your review early.VI. 文献综述主要部分的细节性提示和注意事项主要部分细节提示：引言(Introduction)引言是文献综述正文的开始部分，主要包括两个内容：一是提出问题;二是介绍综述的范围和内容。

文献综述英文作文In recent years, there has been a growing interest in the impact of social media on mental health. Many studies have found that excessive use of social media can lead to feelings of loneliness, anxiety, and depression. This has raised concerns about the potential negative effects of social media on individuals' well-being.The concept of mindfulness has gained popularity as a potential intervention for improving mental health. Mindfulness involves paying attention to the present moment and accepting it without judgment. Research has shown that practicing mindfulness can reduce stress, improve mood, and enhance overall well-being.There is also a growing body of literature on the relationship between physical activity and mental health. Regular exercise has been found to have a positive impact on mood and can help reduce symptoms of anxiety and depression. This has led to an increased focus onincorporating physical activity into mental health treatment and prevention programs.The use of technology in mental health treatment has also been a topic of interest. With the development of digital mental health interventions, individuals can access therapy and support through online platforms and mobile apps. This has the potential to increase access to mental health care and provide support to those who may not have access to traditional in-person services.The role of genetics in mental health has been another area of research. Studies have shown that genetic factors can contribute to the development of mental health disorders. Understanding the genetic basis of mentalillness can help inform treatment approaches and improve outcomes for individuals with these conditions.In conclusion, there is a wide range of research on various aspects of mental health, including the impact of social media, the benefits of mindfulness, the relationship between physical activity and mental well-being, the use oftechnology in mental health treatment, and the role of genetics in mental illness. This diverse body of literature provides valuable insights into the complex nature of mental health and offers potential avenues for improving mental well-being.。

关于“The Code Hero Image of AmericanCulture in the Brave Heart ”之文献综述学生：谈乐天指导老师：孙艳淮南师范学院外语系2015届引言自从美国著名作家厄尼斯特.海明威在他的小说中开创了一种全新的写作形象——硬汉形象（即准则英雄Code Hero）。
后来的很多年，直至现在，中外都有众多的作家或者是导演，又或是其他的文艺创作者们，都学习并应用了海明威的这一文学艺术形象，令现如今的文学世界增添了一道亮丽的色彩。
而在众多学习、研究或是沿用“硬汉形象”这一文学艺术形象的作品中，我所侧重的是1995年好莱坞电影《勇敢的心》中的硬汉形象研究。
众所周知，《勇敢的心》是一部史诗性的大片，由梅尔.吉布森导演并主演，片中的威廉.华莱士是一个崇尚自由，热爱民主，追求爱情，并且拥有强大个人能力以及无坚不摧的意志力的人。
事实上，威廉.华莱士一人，历史上确有其人。
13世纪的不列颠岛，苏格兰人民与英格兰统治者之间的抗争一直都在进行着。
而威廉.华莱士就是此时期出现的一个英雄，一个硬汉。
那么，本文就主要探讨和研究这部电影和其中的“硬汉形象”吧。
一、研究历史什么是硬汉形象（或者说是准则英雄）呢？硬汉形象就是海明威在他的一系列作品中描写的那些具有身体和心里潜力的、崇尚自由和尊严的、拥有强大技能的，同时敢于面对和克服困难和死亡的文学艺术形象。
比如，《老人与海》（The Old Man And the Sea）中的圣地亚哥，《太阳照常升起》(The Sun Also Rises)中的杰克•巴尼斯，还有《丧钟为谁而鸣》(For Whom the Bell Tolls)中的罗伯特•乔丹以及《永别了，武器》（A Farewell to Arms）中的亨利，等等。
现在的文学艺术世界拥有这一形象的原因，全归功于海明威的创造。
而海明威作为一名举世闻名，甚至将是流传千古的作家，自他之后，已经有很多中外的学者专家们把研究的对象转向了他，同样转向了由他开创的“硬汉形象”。

Modern office building integrated design researchIn 1, the demand of environmental protectionThe earth is our common home, development of human civilization in the history also paid heavy price, the human living environment worsening. The protection of the earth, love for the environment, maintaining the ecological, realize the sustainable development, has become the government and the common people the focus of attention. Office buildings in its energy consumption and environmental pollution etc, be the first to bear the brunt, office buildings ecological trend of course has become a historical necessity, mainly reflected in the energy saving, environmental protection, use of materials and the quality of the space environment and other aspects of the improvement. Environmental protection has always been around the social construction of sustainable development and person and natural harmonious relationship problems, determines the current office building environmental protection, energy-saving development factors.To successfully achieve this purpose, the building must benefit from can complete a series of objectives of comprehensive design. The new train of thought is the natural energy ( solar energy, wind energy, natural lighting, natural ventilation ) and artificial systems ( lighting, air conditioning and building management system) combined, its main technical means are: one, with new photovoltaic panels for solar energy electric energy to provide power for added; two, by the middle of the adjustable visor double-layer outer wall of air convection effect to improve the indoor environment and energy consumption; three, to implement the water cycle to provide supplemental source; four, with a wind turbine to generate electric power.In 2, the needs of humanityOffice space design of the service object is the one in which the work of the staff, so it needs to consider many aspects, related to science, technology, humanities, art and other factors. Comfortable office space can not only make people have a sense of satisfaction, stimulate the work enthusiasm and creativity, but also enhance the intellectual labor effect. Comfort is around office building value is one of the important factors.Due to the production of high efficiency, life focus and the competition pressure, the requirement to construction from the enjoyment of the material to the spirit of joy pursuit, aesthetics, ecology, psychology, sociology, residential human ergonomics, behavior science and other disciplines will be reflected in the building, architectural culture and emotional fusion. The design of office buildings and stressed that "people-oriented" concept, through the exchange of people and communication to create a kind of humanized space. Public space and architectural space in the hall the bottom was also developed and more humane. The last office buildings are often indifferent boring, can only provide monochromatic cold space. Now, a variety of stone for the design offers a wide variety of colors and patterns. Wood and glass is often used in public space, interior and landscape design is introduced to high-rise buildings. Bamboo, trees, flowers and other green often give public space (such as the entrance lobby space ) humane features.3, the tendency of diversificationAs the office and efficiency change and improve, will inevitably lead to changes in office scale and office space, industrial era, hundreds of thousands of people in the large-scale space group office approach is obviously be inopportune or inappropriate, small scale, specialization, systematization of modern office form mainstream. In addition to government agencies and large financial institutions, it has been difficult for us to see in the city office building is an enterprise in the office. As a result of office system more professional and complex, the building has a composite function. Office forms are derived from office apartment, hotel type office complex office building. Can say, modern office building is not only the staff offices, and often is a set of office, residential, home, exhibition, culture, business, catering, entertainment, social, as one of a comprehensive building.现代化办公建筑的整体化设计研究1、环境保护的需求地球是我们人类共同生活的家园，在人类文明发展的历程上也付出了沉重的代价，人类的生存条件日益恶化。
保护地球、热爱环境、维护生态、实现人类的可持续发展，已成为了各国政府和人民的共同关注的焦点。
