The features of Sichuan folk furniture material, technology and structure were analyzed through literature review, field investigation and expert interview methods, the technical characteristics of Sichuan folk furniture were re-analyzed from craft aesthetic perspective rather than the traditional material and technique research perspectives. The study shows that Sichuan folk furniture technical features contain not only cultural spirit and aesthetic consciousness, but distinctive aesthetic personality as well. Sichuan folk furniture technical characteristics convey Chinese traditional design philosophy, such as theory is based on objects, and it is highly concentrated and concise of aesthetic sentiment in Sichuan folk aesthetic temperament and interest.展开更多

The development of new situation requires that college English teachers should also strengthen students＇ cultural content education and cultivate students＇ cross-cultural consciousness, in order to stimulate students＇ learning interest, optimize students＇ knowledge structure and improve students＇ social cultural ability while introducing language knowledge and conducting listening, speaking, reading and writing training for students. Then, how to cultivate students＇ cross-cultural consciousness in college English teaching？ This paper takes it as the theme for analysis, hoping to improve college English teaching quality.展开更多

In this paper, the issues currently facing vocational English education was of, and the corresponding countermeasures. With the development of economic and trade globalization, increasingly strengthened international exchanges. Society is not only high-level personnel to graduate raised higher and higher English proficiency requirements, the ability to develop applications based English Education in Higher Colleges also put forward higher requirements. Vocalional Training Colleges for professional and technical personnel is an important part of our personnel training requirements for rapid economic development of professional and technical personnel in addition to high technical expertise, but also need to understand the professional literature information inquiry, learning and further education. Therefore, we must from the height of the times and the needs of international competition to recognize new opportunities and challenges of English teaching in higher vocational colleges are facing a variety of approaches and strive to improve our English teaching level.展开更多

Its chief aims four-fold： First, to promote the students＇ learning motivation; second, to increase the students＇ learning interests; third, to raise their English abilities by reading theme-based/oriented topics; and, fourth, instruct them by giving guidelines to make Power-Point presentations in class. A prior or pilot survey was conducted to provide empirical opportunities to collect and explore the participants＇ views, comments, and opinions in relation to the selected research questions on this topic. The results also indicate that students can speak different/various length of words, utilize appropriate phrase to express their ideas or goals, and to speak in various/different paces, etc. Teachers couldn＇t assess the students only by their test results due to the different learning styles adopted by individual students; however, through this survey, students can be better assisted through the identification of their individual styles or habits, their individual styles or habits of learning. As regards relevant knowledge about their students＇ learning styles, teachers may consider whether and how to adjust their methods of teaching in order to better motivate them to learn English more effectively and efficiently.展开更多
