A Study in Dynamics of BEI Expression in 3 Prefectures in Northern Kanto Region

在北方关东地区进行了关于BEI表达的调查，以了解中、老年人的偏好。发现地区差异显著，使用BEI表达的意识在栃木较高，茨木较低。当然，年轻人和中年人之间也存在代沟。年轻人对BEI的表达有明显的使用或不使用之分。性别差异不显著，但男性对“被”字的使用意识更强;显性“被”字的表达没有显著的地区差异。但继发性BEI表达存在地区差异。在生成方面，中年人使用的“被”的表达方式较多，如“意愿”、“请求”等，而不是“猜测”。

A survey about BEI expression is carried out in the northern Kanto region to find the preferences between young-aged and middle-aged generation.Regional differences are remarkably found; while awareness of using BEI expression is high in Tochigi, Ibaraki was low. Of cause, there is also a generation gap between the young and the middle-aged people. The young people are clearly divided into use or non-use of BEI expression. Gender difference is not significantly observed, however the male had higher awareness of their usage.As for Dominant-BEI expression, there are not significant regional differences. However, the secondary BEI expression has regional differences. As for generation, the middle-aged people use a variety of BEI-expression such as "will" and "solicitation" rather than "guess".
