Through a dozen years of English learning, some of them have high ability of passing examinations, but the practical application ability is barely satisfactory with relatively poor listening level and oral expression ability. The objective cause for this situation is the relatively single and stylization English teaching model used by traditional colleges and universities. This model only emphasizes learning on class which greatly harms students＇ English learning enthusiasm and initiatives. The result is that although the students passed CET4 and CET6 long time before their graduation, they still not dare to open their mouth to speaking concerning face to face English communications. Over the years, the researches on how to improve college students＇ English application ability never stop and they did obtain some achievements and show some opportunities, for example, if we can bring APP （application programs） into college English listening class, it will largely meet students requirements on English learning and this can also replenish and perfect traditional English teaching model.展开更多
