The analysis of the differentiation of be-passive and get-passive

被动语态和主动语态的不同，已经被很多语言学教授和学生讨论过了。本片论文的观点是当语言结构服务于意义表达的功能时，语言的意义是学习的重点。本文从历史观的角度来分析主动语态的用法，也就是说主动语态中“get”的使用是刚发展起来的。除此之外，作者还试着运用由Lackoff提出的ICM（理想化认知模式）理论和由Croft提出的EICM（ICM的活动）来分析被动语态和主动语态不同的认知。而且，这篇文章给出了被动语态和主动语态在使用细节上的不同。本文作者旨在明确区分被动语态和主动语态的用法，以此帮助高中学生或者大学英语教师来分清两者之间的差异。

The differentiation of be-passive and get-passive is discussed by a lot of linguistic professors and students. The idea of this paper is that meaning is so central to language that it must be a primary focus of study while linguistic structures serve the function of expressing mean- ings. This paper uses the historical point of view to analyze the usage of get-passive. That is, the passive use of ＂get＂ is developed from the inchoative use. Besides, the author tries to use ICM （idealized cognitive model） theory proposed by Lackoff and EICM （event of ICM） which is put forward by Croft to analyze the differentiation of be-passive and get-passive cognitively. Also this paper gives other differences between the use of be-passive and get-passive in detail. By this paper, the author aims to make clear the difference between the usage of be-passive and get-passive in order to give some help to the high school or college English teachers to explain the difference between the two.
