关于英语教学的文献综述范文The field of English language teaching (ELT) has been the subject of extensive research and scholarly discourse, with a vast array of literature exploring various aspects of this dynamic and evolving discipline. In this literature review, we will delve into the key themes, approaches, and perspectives that have shaped the understanding and practice of English language teaching.One of the fundamental areas of focus in ELT research has been the exploration of different teaching methodologies and their effectiveness. The traditional grammar-translation method, which emphasizes the study of grammatical rules and the translation of texts, has been challenged by more communicative approaches that prioritize the development of language proficiency for practical usage. The communicative language teaching (CLT) approach, for instance, emphasizes the importance of authentic communication, task-based learning, and the integration of the four language skills (listening, speaking, reading, and writing) to foster real-world language use (Savignon 2002).Closely related to the methodological debates is the ongoing discussion surrounding the role of the native language in the ELT classroom. While some scholars advocate for a strict target language-only policy, others argue for the judicious use of the learners' first language to facilitate comprehension, provide grammatical explanations, and address cultural differences (Cook 2001). This tension has led to the emergence of translanguaging pedagogies, which recognize the value of students' linguistic repertoires and encourage the strategic use of multiple languages to enhance learning (García and Wei 2014).Another significant area of ELT research focuses on the learner-centered approach, which emphasizes the individual needs, learning styles, and strategies of language learners. This perspective recognizes that students come from diverse backgrounds and have unique preferences, motivations, and cognitive processing abilities, which should be taken into account in the design and delivery of language instruction (Nunan 1988). Consequently, there has been a growing emphasis on the incorporation of learner autonomy, self-directed learning, and the use of technology-enhanced language learning to empower students and foster their active engagement in the learning process (Benson 2011).The role of technology in ELT has also been a subject of extensive investigation. The integration of digital tools, such as onlineplatforms, mobile applications, and multimedia resources, has transformed the landscape of language teaching and learning. Research in this area has explored the potential of technology to enhance language input, provide interactive and personalized learning experiences, facilitate collaborative learning, and support the development of language skills (Chapelle and Sauro 2017).In addition to methodological and technological considerations, ELT research has also delved into the sociocultural and political dimensions of language learning and teaching. This includes the examination of the influence of cultural backgrounds, power dynamics, and language ideologies on the teaching and learning of English as a global language (Pennycook 2017). Scholars have also explored the challenges and opportunities presented by the increasing diversity of English varieties and the need to address issues of linguistic imperialism, identity, and the representation of non-native speaker perspectives in the ELT field.Furthermore, the field of ELT has witnessed a growing emphasis on the importance of teacher education and professional development. Researchers have investigated the knowledge, skills, and dispositions required for effective language teaching, as well as the impact of pre-service and in-service teacher training programs on the quality of instruction (Richards and Farrell 2005).Finally, the assessment and evaluation of language learning outcomes have been a significant area of focus in ELT research. Scholars have explored the development and implementation of valid, reliable, and fair assessment tools, as well as the alignment of assessment practices with the goals and objectives of language instruction (Bachman and Palmer 2010).In conclusion, the literature on English language teaching presents a rich and multifaceted landscape, encompassing a wide range of perspectives, approaches, and areas of inquiry. From methodological debates to the integration of technology, from learner-centered pedagogy to sociocultural considerations, the ELT field continues to evolve, driven by the ongoing efforts of researchers, practitioners, and policymakers to enhance the quality and effectiveness of language education.。

Introduction:Good morning/afternoon, esteemed colleagues and fellow researchers. Today, I would like to present a comprehensive literature review on the impact of climate change on agricultural productivity. As the global climate continues to change, understanding the implications of these changes on our food systems is crucial for developing effective adaptation and mitigation strategies. This review aims to summarize the existing research and highlight the key findings regarding the impact of climate change on agricultural productivity.1. Introduction to Climate Change and AgricultureClimate change refers to long-term shifts in temperature and weather patterns that are primarily driven by human activities, particularly the burning of fossil fuels. Agriculture, being highly dependent on climate and weather conditions, is particularly vulnerable to the impacts of climate change. The primary concerns include changes in temperature, precipitation patterns, extreme weather events, and rising sea levels.2. Temperature Changes and Agricultural ProductivitySeveral studies have shown that rising temperatures can have significant negative impacts on agricultural productivity. Higher temperatures can lead to heat stress in crops, reduced water availability, and increased pest and disease pressure. For instance, a study by Lobell et al. (2011) found that increasing temperatures have led to a decrease in wheat and maize yields in the United States.3. Precipitation Patterns and Agricultural ProductivityChanges in precipitation patterns are another critical factor affecting agricultural productivity. Droughts, floods, and changes in the timing and distribution of rainfall can all impact crop yields. A study byInter-Ministerial Group on Climate Change (2014) in India highlighted the adverse effects of frequent droughts and floods on agricultural productivity, particularly in the context of rainfed crops.4. Extreme Weather Events and Agricultural ProductivityExtreme weather events, such as hurricanes, cyclones, and heavy rainfall, have become more frequent and intense due to climate change. Theseevents can cause significant damage to crops, infrastructure, and livelihoods. A study by Dhakal et al. (2014) in Nepal revealed that extreme weather events have led to a decrease in agricultural productivity, particularly in the rice and wheat sectors.5. Climate Change and Pest and Disease PressureClimate change can also influence the distribution and prevalence of pests and diseases that affect crops. Warmer temperatures and changes in precipitation patterns can create favorable conditions for pests and pathogens, leading to increased crop damage. A study by Kort et al. (2016) found that climate change has led to an increase in the spread of pests and diseases in agricultural systems.6. Adaptation and Mitigation StrategiesTo address the challenges posed by climate change, various adaptationand mitigation strategies have been proposed. These strategies include developing drought-resistant crop varieties, improving water management practices, implementing precision agriculture techniques, and promoting sustainable land management practices. A study by Vermeulen et al. (2010) emphasized the importance of integrated approaches that combine multiple adaptation strategies to enhance agricultural productivity under changing climate conditions.7. Research Gaps and Future DirectionsDespite the extensive research on the impact of climate change on agricultural productivity, several research gaps remain. Furtherresearch is needed to understand the complex interactions betweenclimate change, agricultural systems, and socioeconomic factors. Additionally, more research is required to develop and evaluate the effectiveness of adaptation and mitigation strategies tailored tospecific regions and crops.Conclusion:In conclusion, this literature review has provided an overview of the existing research on the impact of climate change on agricultural productivity. The evidence suggests that climate change posessignificant challenges to our food systems, particularly in terms of temperature changes, precipitation patterns, extreme weather events, and pest and disease pressure. To mitigate these challenges, it is crucial to implement effective adaptation and mitigation strategies. Further research is needed to address the remaining gaps and develop sustainable solutions for the future of agriculture under a changing climate.References:- Lobell, D. B., Bala, G., & Caldeira, K.

Literature review on Analysis of government investment projects bidding of engineering quantity list Abstract: Most of government investment projects are people's livelihood, infrastructure projects, they are usually huge capital investments. The bid for government investment project as a research object in this article, research history and status of bidding system at home and abroad for literature review, proposed research methods on the basis of this, and offer some direction for government investment project bidding of engineering quantity list.Keywords:Government investment projects, Engineering quantity listing, Bidding, A literature review0IntroductionGovernment refers to investment projects in order to adapt and promote the development of national or regional economy. In order to meet the community's culture and life needs, as well as take into account for political, defense and other factors, from local finance financial investment by the Government to issue bonds or bonds, foreign government grants, as well as the State financial guarantees for loans from domestic and international financial organizations, including wholly-owned or joint-venture construction of fixed assets investment projects. According to 《People's Republic of China bidding law》tender scope of application of the provisions, most government investmentprojects need bidding. Government investment projects is an important part of investment in fixed assets in society. Especially global economic crisis has not been completely eliminated in the current , in case of expanding domestic demand, increasing infrastructure investment policy measures form our government, government investment project play a vital role , to be reckoned with, and its social impact on the country and even the world is major. So it is more likely to be the public concern. Government investment projects are special, it is different from the enterprise investment projects. Investors and owners was divided between the two sides of government investment project. And most of government investment projects have non-profit characteristics. Model of project bid invitation and bidding is short of improvement,and supervisory system exists leak. There are many problems in the bidding about government investment projects, Endless stream of breeding corruption, causing huge waste and adverse bad effects in society. Therefore, the management of Government investment project is an important issue which we need to address, and bidding as one crucial aspect is a top priority that we resolve the issue.At present, in China there are a large number of investment projects .The Government must ensure the smooth and efficient implementation of these projects, look forward to these investments can give us better chain reaction in the market, and help us out of the currenteconomic difficulties. In view of this, we have to guarantee the implementation of these investments.1Research history and status at abroadDate back to 1944, Aimubulang doctoral dissertadissertation for more systematic research about Bidding problem. [1] Firedman published bid research in journals at the earliest. He sealed bids on the Firedman model in 1956 and published in the journal of Operations Research.[2] Since then, Wai, John Thurman and scholars made a lot of research work in this area, and published hundreds of papers.[3][4]Many of the scholars puted forward a new model on the basis of the Firedman mode , such as Gate model, Hanssman-Rivett model, Case-shaffer model, Willenbrock model. United Kingdom present first engineering quantity list valuation. United Kingdom Royal Society of Surveyors (RICS) prepared and published construction rules of calculation (SMM) in 1905, a United Kingdom unified rules for calculation of construction quantity. RICS establishment, has enacted a series of calculation rules and code of conduct, regulations, standards or SMM7 comprise the United Kingdom engineering cost management system. At the same time, United Kingdom to RICS SMM7 compiled by project quantity list bidding, engineering quantity detailed list by building owners, independently by contractors according to their own criteria and project specific quotes.2Research history and status at homeConstruction project bid is the bid contract construction project, according to legal procedures, to public tender or invitation to tender to encourage potential bidders based on the tender documents to compete through evaluation, selection of selected winning bidder of an economic activity. Symmetry concepts of construction project bidding is tender, are legally qualified and competent bidders, according to the tender conditions, completed within the specified time limit bids, the bid, attend the opening, and assessed, whether waiting for successful economic activities.

Bidding should follow the principles of openness, fairness, impartiality and good faith, and this principle is the inherent requirement of market economy. In developed countries, the study on bidding mechanism and its implementation mechanism has evolved to a more mature phase. Bidding system in China from reform and opening up began, after more than 30 years of gradually improving, slowly realize the construction rules, laws, policy development and implementation of regulations, standardizeconstruction market order, guarantee the quality of construction.Bidding theory research began in the late 1980 of the 20th century in China, such as bidding model xiaoweipin made in 1987, made Long Aixiang engineering project bidding decision model of dynamic, Department of civil engineering, Tsinghua University, development of practical international project bidding and expert system for mathematical ESBOP, and Dr Y ang Lanrong in 2000, a rate determine the decision-making model of bidding. Because the proposed tendering of Bill of quantities in China in 2003, previous research was mainly on the theory of bidding decision ,application and bidding evaluation method of the model, such as the popular use of comprehensive evaluation method, lowest bidding method and so on. In the promotion process of the tendering of Bill of quantities, Chinese scholars conduct a lot of research on the tendering of Bill of quantities .Such as Wu Qiang published research on the ideal of engineering quantity list valuation mode in the construction of the economic magazine, Cheng Hu presented engineering quantity list valuation which effects on China's current contract on the infrastructure optimization implementation, Wang Lei published under engineering quantity list bidding mode of research on bidding mode of military engineering, Shi Xiya [5]and afforestation [6] proposed base price has a prior commitment, control costs effectively, and help to control that the bidders will be marked with a certain, bybidding activity study on bidding and bid evaluation methods, Cao Jiming [7]makes a discussion on project bidding without; Li Xinzhong[8] explores methods of tendering of Bill of quantities in theory; Y uan Xiawei [9] pointed out the inadequacy of the present bidding methods, and analied the characteristics of the method of tendering of Bill of quantities; Xia Neng An analys the advantage of engineering quantity list quotation and effects on bidding [10].3Research PurposeAt present, China has a large number of Government investment projects and the Government must ensure that these items smoothly and efficiently implementation. To look forward to these investments can bring better reaction to our markets, helping us out of the current economic difficulties. In view of this, we have to guarantee the implementation of these investments.Look forward to this article through the analysis of the advantages and disadvantages of government investment projects tendering of Bill of quantities and countermeasures, in the full analysis of engineering quantity list bidding mode of government investment project in China based on the advantages and disadvantages of, we can establish a set of appropriate for the current situation of our country, can truly commensurate with the engineering quantity list valuation mode of government investment project bidding mechanism and mode of runningto perfection of construction bidding market, It can Improve construction bidding market, to such an extent as to control effectively and make use of government investment, stimulate and drive the market, improve market efficiency, optimize the industry structure, implement excellence, and promote healthy development of the Socialist market economy.4 Study on methods and contentOn the basis of analysis, research theory and method on domestic and international bidding, the article identify the causes of these problems, and propose specific measures to address these issues for government investment project bidding of engineering Bill pricing in the area since the issue of in-depth systems analysis. This demonstration uses analytic hierarchy process-related knowledge and analysis.On this basis, all runs of the engineering construction tender bids the system links the implementation of reconstruction, seeking a truly appropriate for the current situation of our country under the mode of valuation with Bill of quantities of bidding to run the new mode, to refine the engineering quantity list bidding system in China.Under the mode of valuation with Bill of quantities at home and abroad at the moment, this article makes comparative studies on the Government investment project bidding activity on effective operation of a system . Framework of the establishment of comprehensive study onbidding of construction engineering has been established,analysising in-depth the advantages and disadvantages of bidding mechanism under the mode of valuation with Bill of quantities, and using scientific methods for analysis and improvement, a set of appropriate for the current situation of our country which can truly commensurate with the engineering quantity list valuation mode of government investment project bidding mechanism and operating modes has been established .finally.
