摘    要

跨文化交际是指本族语者与非本族语者之间的交际, 也指任何在语言和文化背景方面有差异的人们之间的交际，是第二语言学习不可分割的组成部分。不同文化背景造成人们说话方式或习惯不同, 从而产生理解上的冲突和矛盾。而现在随着网络的普及，它们越来越多的是用于人际交往,即以计算机为中介的网络交际或简称网络交际。跨文化交际的发生比以前任何时候都要容易和频繁。
基于网络的即时通讯手段，如即时消息，视频通话，以及非即时通讯手段，如电子邮件，使得在校学生在平时生活中有了更多学习外语的机会，也同时大量的接触到了跨文化交际的情形。不同形式的网络交际对于学生提高自己外语使用能力和文化敏感度有怎样的不同，什么手段对于学生的外语能力培养最有帮助？这样的研究非常实际也十分必要。
本文分析了网络视频通话，即时消息和电子邮件作为即时通讯和非即时通讯的三种典型的代表，对大学生外语能力培养的影响。本文的研究对于了解网络交际对于大学生跨文化交际的影响有十分重要的意义。
