“被+X”是2009年网络上兴起的新型结构，2011年前后达到流行高峰，之后使用热度逐步下降，保持较为平稳的状态。“被+X”的发展演变是当代汉语流行语发展变化的一个缩影，文章以其为代表，初步探究当代汉语流行形式发展演变的过程。 文章首先横向考察了最早产生的“被+X”的基本特征。“被自杀”“被就业”是最早出现的基本形式，文章从形式、功能、意义、感情色彩四个角度，概括了其基本特点。从形式上将“X”的韵律结构和词类表现归纳为[＋双音节][＋不及物动词]；从功能上将其主语归纳为[＋指人]，从语义上将其归纳为[﹣真实][﹣自愿]；感情色彩则为[＋负面]。以上基本特征是“被+X”发展演变的初始平台，此后所有的发展变化，都表现为对上述一个或几个特征的突破。因此，以此为基础，可以考察与描述每个特征下“被+X”的发展演变。 文章重点从历时的角度，围绕基本特征，运用定性分析与定量分析相结合的方法，考察了每一个特征下“被+X”的发展演变。从形式的角度看，随着“被+X”的可接受度有所增强，使用范围变广，越来越多的“X”能够进入“被+X”结构，“X”在韵律方面突破双音节模式，“X”前后均可增加成分，用于补充“X”持续的时间、导致的结果等；从而改变了整个“被+X”的韵律模式，“X”完成了由［＋双音节］到[±双音节]的变化；在词性上，通过分类、统计得到的具体数据，直观地看到“X”的词类拓展，表现为由[＋不及物动词] 到[±不及物动词]。从主语的角度看，不具有主观情感的事物名词也进入该形式，实现了由[＋述人]到[±述人]的突破。语义上，大部分结构保持[﹣真实][﹣自愿]的语义特征，但违实性和非自愿性均有所减弱，且可以互相组合。另外，“被+X”的一形多义现象增多，施受对象发生了变化，语义变得越来越复杂，需要结合语境，才能得出全面的语义内涵。从感情色彩角度，出现了中性色彩的用例。 最终，发展演变到当下，“被+X”的特征可以总结为：形式上，［＋不及物动词］→[±不及物动词]，［＋双音节］→[±双音节]；功能上，[＋述人] →[±述人]；语义上，[﹣真实][﹣自愿]→[±真实] [±自愿] ；感情色彩上，一方面可以通过多种手段不断强化感情色彩，另一方面也出现了非负面的用例。“被+X”的发展演变体现了迅速性、去范畴化、逐渐分化的特征。从典型的“被+X”到非典型的“被+X”，其发展演变轨迹代表了一种流行语言形式在语言系统中发展变化的过程。它的兴起是人们追求语言表达多样化、生动化的结果；它的形式和意义的发展变化，是人们追求表义更加完整、精细的结果；它内部的形式或稳定或衰减，是一种流行语逐渐在语言系统中分化的结果

In this paper, new construction "Bei +X" is taken as the research object. "Bei + X" is a new type of structure that emerged on the Internet in 2009. It reached the peak around 2011. After that, the fever declined gradually and restored to a stable state. "Bei + X" is a microcosm of the change and development contemporary Chinese. Taking "Bei + X" as a representative, this paper preliminarily explores the development and evolution of contemporary Chinese. Firstly, the basic form of "Bei + X" is inspected horizontally, and the basic characteristics are summarized. "Be forced to suicided" and "be employed" are the first basic forms of "Bei + X". The basic features of "Bei + X" are investigated from the aspects of form, function, meaning and emotional color. Formally, the prosodic structure and part-of-speech expression of "X" can be summarized as [+disyllable] [+intransitive verb].Functionally, the subject is summed up as [+referring to person].Semantically, it can be classified as [-reality] [-willingness]; emotional color is [+negative].The above characteristics become the foundation for investigating its development and evolution. From a diachronic point of view, focusing on the basic features, this paper uses qualitative description and analysis to examine the development and evolution of “Bei + X” by each feature. From a formal point of view, with the acceptance of “Bei+X” being enhanced and the scope of application becoming wider, more and more "X" can enter the "Bei+X" structure."X" breaks through the two-syllable pattern in prosody. Both before and after "X" can add components to supplement the duration of "X" and the resulting results. Thus, the whole prosodic pattern of “Bei+X” is changed, and "X" completes the change from [+disyllable] to [±disyllable].From the aspect of part of speech, we can see the expansion of the part of speech of "X" intuitively from [+intransitive verb] to [±intransitive verb] through the specific data obtained by classification and statistics. From the subjective point of view, the noun of things without subjective feelings has also entered this form, achieving a breakthrough from [+narrator] to [±narrator].Semantically, most of the structures retain the semantic features of [-reality] [-willingness], but the irregularity are weakened and can be combined with each other.In addition, the polysemy of “Bei + X” has increased, the object of giving and receiving has changed, and the semantics has become more and more complex. It is necessary to combine the context in order to get a comprehensive semantic connotation. From the point of view of emotional color, there are cases of neutral color. Ultimately, the characteristics of “being + X” can be summarized as follows: Formally, [+intransitive verb] to [±intransitive verb] ,[+disyllabic] and [±disyllabic]; functionally, [+narrator] to [±narrator] ; semantically, [-reality] [-willingness] to [±reality] [±willingness]; emotionally. On one hand, emotional color can be continuously strengthened by various means. On the other hand, there are also non-negative using cases. The development and evolution of "Bei + X" embodies the characteristics of rapidity, de-categorization and gradual differentiation. From the typical "Bei + X" to the atypical "Bei + X", its development and evolution track represents the development and change of a popular language form in the language system. Its risingresults from people's pursuiting? of diversification and vividness of language expression; the development and change of its form and meaning results from people's pursuiting? of more complete and refined meaning; its internal form ,stability or attenuation results from the gradual differentiation of Catchwords in the language system.
