高职院校当中的商务英语知识教学讲究的是商务知识与英语技能的完美结合,是一门实用性强、应用范围广、信息量大的课程,在现代经济中具有重要的作用。而在经济技术和信息化高速发展的今天,已经步入微时代的商务英语函电教学,相较于传统的英语函电教学模式来说具有特天独厚的优势。结合商务英语函电教学特点,利用先进的互联网知识简单论述微课程模式在提高学生商务英语函电写作水平和应用能力方面的重大作用,希望对现实中的英语教学有一定的指导意义。 The teaching of business English in higher vocational colleges emphasizes on the perfect combination of business knowledge and English skills. It is a practical, widely used and informative course, which plays an important role in modern economy. Today, with the rapid development of economy, technology and informatization, business English correspondence teaching has entered the era of micro-times, which has a unique advantage over the traditional English correspondence teaching mode. Combined with the characteristics of business English correspondence teaching, using the advanced knowledge of the Internet to briefly discuss the important role of the micro-curriculum in improving students’ writing ability and application ability of business English correspondence, I hope to provide some guidance to English teaching in practice.
