Recent years,many high schools enlarged their dimensions of enrollment along with the colleges’enlarged enrollment.As a result,the vocational schools’enrollees are mostly the graduated junior high school students who are not qualified to enroll in the senior high schools.The researcher found many students didn’t have interests in English reading.They often chat,read novels,or even sleep.That badly interrupted the accomplishment of regular teaching process.Most of the colleagues of the researcher contributed that to the lowered quality of students.But there might be many further reasons decreased the students’reading interests,such as,the teachers’teaching methods,the applicability of the textbooks,the teaching environment,and etc.Many researches had been conducted on the issue of the English reading.But there are a few practical researches on how to enhance students’interests in English reading.The researcher hypothesized that the communicative teaching activities(shortened as CTA hereinafter)can enhance students’reading interests.A three-week project was conducted among 35students.CTA was arranged in each of the three stages of English reading teaching,namely the pre-reading stage,the while-reading stage and the post reading stage.The researcher analyzed the weekly diary that described the performance changes of students,and also the exercise marks they got in the classes in three weeks.The results turned out students’interests in English reading had been highly improved after the application of CTA.The significance of this project is that the application of communicative teaching activities can enhance students’reading interests.And those teachers who are meeting the same problem in their teachings can benefit from this project. 展开更多

This article makes an integral and comprehensive study on the process of regional brand enhancement based on agricultural industry clusters using the theories of industrial clusters and regional brands.By analyzing the key determinants in the process of regional brand enhancement based on agricultural industry clusters,we establish a systemic theory system.The results show that as an important mediator in the process of regional brand enhancement based on agricultural industry clusters,the construction of value chain system is of vital importance.Other factors, such as the government guidance and service,the promotion of industry associations and professional cooperatives,play a key regulating role in this process. 展开更多
