Introduction
Since the beginning of the 21st century the study of concept has drawn attentions of linguists since its unignorable role in realization of main ideology in a period of time and has been regarded as one of the main ways to understand the system of human thought and the nature of the human psyche. (Ангелова, 2004; Елмслев, 1960) Studying concepts gives linguists a different aspect to understand collective consciousness of society, nations and cultures.  On the opinion of George Orwell, the word “crisis” is often used in different kinds of political discourse, such as political speech, political writing, public communication (ADDIN CSL_CITATION {"citationItems":[{"id":"ITEM-1","itemData":{"author":[{"dropping-particle":"","family":"Landtsheer","given":"De","non-dropping-particle":"","parse-names":false,"suffix":""}],"id":"ITEM-1","issued":{"date-parts":[["2012"]]},"page":"87-107","title":"Politically Speaking : A Worldwide Examination of Language Used in t ...

When “crisis” appears in a discourse, it means that an issue is urgent and threatening to current status, so it is necessary to take several actions to avert a peril (Laura Henderson, 2014). However, the concept of crisis has more than one definition in English and Chinese. For example, in Chinese explanatory and etymological dictionaries “crisis” also means “latent harm or danger” (Xinhua Dictionary), “an extremely dangerous moment” (Mandarin Dictionary of the Ministry of Education). Due to the dynamic of concepts of crisis and its influence on human activities, to analyze it seems important.  Ten Lei’s work “the concept of empire in modern Russian-speaking political discourse” discusses the concept of “empire” in Russian, its lexicographic representation and its interaction with the Russian society. Tatiana Prokofieva (2006) in her thesis devoted to the concept of crisis in modern political discourse has studied the conceptual framework of human being which comprises the concept of crisis and analyzed its verbalization in political discourse. Kondratieva О.N. (2012) has turned her study of the concept of crisis into Russian and Bulgarian media discourse. Slatin A. I. (2016) has studied the meaning of crisis in Russian political and economic discourse. Mishina М. М. (2013) has given the information that the concept of crisis has been used in speeches, publications more frequently in Russia due to the international incidents and events in her work “actualization of global concepts in political discourse”. The work “Representation of the concept of "crisis" in media discourse” provides not only the concepts of crisis both in Russian and in Chinese, but it also compares the similarities and differences of concepts in these languages in publications. In the field of the concept of crisis study it is still lack of the research direction which aims to identify special linguistic features of concept actualization in different languages, the most used meanings of the lexical unit of crisis and to classify different usage. Taking political discourse as a resource to study the concept of crisis has its relevance. Political discourse serves as a medium to transmit different ideologies, identities and opinions that form concepts of a person. With the development of technology, the connection of individuals tightened, and as a result, political discourse is easier spread across borders. Crisis is usually used as political crisis, economic crisis, energy crisis, etc. in political language. In this thesis, we study its concept based on the contexts, different atmosphere of society, ideologies of time and nations. The object of the thesis: linguistic units of the concept of crisis actualized in political media discourse. The aim of the thesis is to identify special linguistic features of concept actualization in English and Chinese media political language. In accordance with the aim, it’s necessary to implement the following tasks: 1) to compare definitions of the notion crisis in English and Chinese dictionaries; 2) to classify the linguistic features of the lexeme “crisis” in English and Chinese political media discourse; 3) to sort out the verbalization of “crisis” in English and Chinese political media discourse. Materials: this thesis focuses on English and Chinese political media discourses in the following newspapers: the Economist, the New York Times, the Washington Post, 自由時報 (the Liberty Times Net), 新華社 (the Xinhua News Agency), 蘋果日報 (the Apple Daily)… etc. and definitions from explanatory and etymological dictionaries, such as the Oxford Learner’s Dictionaries, the Online Etymology Dictionary, 新華辭典 (Xinhua Dictionary), 教育部重編國語辭典修訂本 (the Revised Mandarin Chinese Dictionary) and the 漢典(Hàndiǎn).  Methods used in this thesis: communicative-pragmatic, linguocultural, descriptive and comparative.   The structure of this thesis. The main body of this thesis is consisted of two chapters. In the first chapter, we do literature reviews regarding the understandings of concept, discourse, media discourse and political discourse.
