Abstract.Communicative Language Teaching (CLT), also known as communicative approach, has witnessed a tremendous growth of research since it was developed by British applied linguists, as an effective approach to L2 learning and teaching. The basic idea of CLT is that language instruction should focus on communicative proficiency instead of on mere mastery of structures. With the guidance of five interconnected principles summarized by Richards and Rodgers, various implementations are realized. However, the implementation of CLT in Asia still encounter a number of difficulties due to some conceptual … Read more →

Abstract.The strategy of rural revitalization is to adhere to the priority development of agriculture and rural areas, further adjust the urban-rural relationship between agriculture and industry, and accelerate the development of agriculture and rural economy, while optimizing the structure of China's agricultural factor endowment is the key to achieve rapid agricultural development and rural revitalization. Through the perspective of new structural economics, this paper discusses the relationship between agricultural factor endowment structure and agricultural institutional arrangement, agricultural … Read more →

Abstract.English writing is a crucial skill for students to learn alongside listening, speaking, reading, writing, and viewing. It involves expressing information, ideas, thoughts, and emotions in written English form. Self-efficacy in English writing is an important factor that affects students’ writing achievement and strategy use. Many scholars have researched the factors that influence it. This paper reviews recent studies on self-efficacy in English writing from both home and abroad by referring to relevant literature. Firstly, it introduces the development trend of existing research through data. … Read more →

Abstract.Technical problems such as the limited control times and time of existing fluid control valves and the inability to accurately control the control opening limit the long-term economic development of deep shale gas. This design is mainly based on PID control algorithm to control the opening of fluid control valve. It has the advantages of unlimited control times, high control precision and strong reliability.

Abstract.Riparian areas are the transitional zones between terrestrial and aquatic ecosystems. Riparian have been experienced serious river channelization, riparian hardening and other anthropogenic activities. These disturbances result in degradation of ecological function and reduction of biodiversity of riparian ecosystems. There are many ecological engineering to restore riparian ecosystems in China. The research results of this article indicate that species richness and the Shannon-Wiener diversity index were: restored sites > natural sites > channelized sites, and biomass of natural sites was … Read more →

Abstract.A 3D simulation model of a single cylinder of a natural gas engine was established. PFI natural gas DI gasoline was used to control the time matching between injection and ignition, so that gasoline could form a small active stratified area near the spark plug. The combustion characteristics under different matching conditions were studied, and finally compared with pure natural gas. It is found that gasoline can be used in large cylinder diameter natural gas engine in a small range, which can accelerate the combustion of natural gas fuel, shorten the time used by CA0-CA5 by 77.6%, shorten the … Read more →

Abstract.This paper discusses how to evaluate the effect of two-child policy in China on fertility. We consider issues both of data and of thestatistical methods that were applied to those data. Then, we review and discuss the development of the empirical studies. At last, we make concludes. Read more →

Abstract.Soil is the largest carbon pool in terrestrial ecosystems, and it is particularly important to study soil carbon pools. In this study, we investigated the effects of intensive agriculture, plant inputs and organic matter inputs on the soil organic carbon pool, and the results showed that intensive agriculture increased the soil carbon pool and soil organic matter content to a certain extent, and increased the rate of carbon sequestration in the soil, but intensive agriculture made the soil more prone to erosion, resulting in the loss of soil nutrients; the plant inputs were mainly in the form … Read more →

Abstract.In recent years, the real estate market has become less popular, and real estate prices in a few places have declined slightly, mainly due to the effect of purchase restriction policies and the slowdown in economic growth. Will it be difficult for the real estate industry to develop in the future? Will the real estate market slump and remain cold for a long time? As some people believe, real estate will definitely not be sold and prices will have to be significantly reduced? I believe that the real estate industry will continue to develop. The long-term price reduction of real estate will not … Read more →
