Characteristics and Problems of CLT

The present paper makes a short introduction about 8 kinds of teaching approaches and methods, later with a focus on the approach of Communicative Language Teaching (CLT). This paper first summarizes the characteristics of CLT, and after that gives the existing problems of CLT, and in the end a conclusion is made. The purpose of this paper is to make a clear understanding of CLT in order to provide some advice to carry out it.     

交际语言教学在中国的可行性

交际语言教学是一种第二外语教学方法。它强调交流既是学习语言的方法,又是学习语言的目的。但是,在目前中国的具体国情下,这种语言教学法很难在我国普遍运用。     

影响交际教学法推广的原因探究

本文主要分析影响交际教学法在中国受到教师和学者的质疑以及学生不受欢迎的原因。本文认为语言环境、教育体制,英语教师等方面的原因共同决定了交际教学法只能在部分地区适合推广来促进中国的英语教学效果和质量。中国的英语教育还需要改革来适应新时期的发展。     

浅析英语交际教学法的本土适应问题

国内一些学者认为,交际教学法注重培养学生的语言交际能力,建立在交际法基础上的任务型教学模式（TBLT）是最好的英语教学方法,因而不遗余力地引进、宣传、提倡和推广这种方法。交际法在我国英语教学中存在一些突出问题,不可对交际法盲从迷信,而应该根据我国外语教学的实际,找到适合国情、教情和学情的教学方法。     

纸笔语言测试与计算机化语言测试的等效研究

本文以我国大学英语教学改革为背景,以非英语专业学生为对象,就PLT与CLT的等效性做一次实证性研究。尽管学生分别在PLT与CLT条件下测试结果有差异,但经SPSS软件统计分析,其差异并不具有统计学上的显著意义,因此笔者得出CLT与PLT等效的结论。随后,笔者进一步探讨了CLT的优劣势,并认为在21世纪的信息时代,CLT终将会成为语言测试的主流。     

Monitoring cropland transition and its impact on ecosystem services value in developed regions of China: A case study of Jiangsu Province

Cropland use is experiencing an intense transition in both depth and breadth with rapid development of the Chinese economy. Unwarranted land use transitions can affect the ecosystem services value (ESV) and ecosystem functions significantly. This paper reports the dynamic patterns of cropland transition (CLT) and its impact on ESV in Jiangsu Province based on land-use data from 1990, 2000, 2010, and 2013, crop yield data, empirical data related to ESV, some revisions adapted to the situation of Jiangsu, and Geo-information Tupu methods. Jiangsu has experienced rapid economic growth and urbanization, which can be seen as a microcosm of China's development. Results showed that the total area of cropland decreased markedly from 1990 to 2013. This loss of cropland took place mainly through the expansion of construction land and water area, accounting for 83.78% and 13.71%, respectively. The gain in cropland came mainly from construction land, water area, grassland, and woodland, accounting for 58.92%, 19.92%, 11.46%, and 10.22%. The transitions from 2000 to 2010 were much more significant than during 1990–2000 and 2010–2013. CLTs were accompanied by relatively concentrated distributions near towns and cities and the distributions in southern and central Jiangsu were more than in northern Jiangsu. Between 1990 and 2013, CLTs gave rise to a decrease of 6.78 million US$ ESV that was mostly caused by the transition from cropland to construction land and water area to cropland. Based on this information, some of the major implications for improving the land use policy and ecological protection policy in China were discussed. These include increased emphasis on land quality and ecological environment in balance between cropland addition and conversion, introducing ESV measures to evaluate the ecological effect of land-use planning, and establish an all-around ecological compensation mechanism.
