【正文】 Again and again we must rise to the majestic height of meeting physical force with soul force. (Par. 6)(35) And as we walk, we must make the pledge that we shall always march ahead. We cannot turn back. (Par. 7)(36)…the sons of former slaves and the sons of former slaveowners will be able to sit down together at the table of brotherhood.(Par. 10)(37)…a desert state sweltering with the heat of injustice and oppression, will be transformed into an oasis of freedom and justice. (Par. 11)(38)…where they will not be judged by the color of their skin but by the content of their character. (Par. 12)(39) With this faith we will be able to hew out of the mountain of despair a stone of hope. (Par. 17)(40) With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood.4. Conclusion As we have analyzed above, stylistic devices are frequently used in the discourse of literary works especially in speech, to achieve certain specific purposes. Thus making the style of a speech somewhat particular to the others.Generally speaking, a speech may have the following stylistic characteristics:To begin with, it must be very persuasive. Thus the sentence patterns are very wellorganized, with repetitions, parallelism and contrasts frequently used.Secondly, it should be emotional so as to be convincing, because the speaker should face the audience directly and his words should not only be orderly and informative but also be expressive and inspiring. Therefore, the stylistic devices such as similes and metaphors are often involved.Finally, in many cases, writtenconversational style is usually used with not very formal diction and not very plicated sentence structure.

It is very useful in the analysis of various styles of writing. In this thesis, the author tries to offer a stylistic analysis of the famous speech by Martin Luther king, Jr. I Have a Dream.1. Introduction: Definition of Stylistics and Stylistic AnalysisAs far as the definition of stylistics is concerned different scholars define the branch of study in different ways. Wales defines stylistics simply as “ the study of style” (1989:437), while Widdowson provides a more informative definition as “the study of literary discourse from a linguistic orientation” and takes “a view that what distinguishes stylistics from literary criticism on the one hand and linguistics on the other is that it is essentially a means of linking the two” (1975:3). Leech holds a similar view. He defines stylistics as the “study of the use of language in literature” (1969:1) and considers stylistics a “meetingground of linguistics and literary study”(1969:2). From what Widdowson and Leech say, we can see that stylistics is an area of study that straddles two disciplines: literary criticism and linguistics. It takes literary discourse (text) as its object of study and uses linguistics as a means to that end.Stylistic analysis is generally concerned with the uniqueness of a text。 that is, what it is that is peculiar to the uses of language in a literary text for delivering the message. This naturally involves parisons of the language of the text with that used in conventional types of discourse. Stylisticians may also wish to characterize the styl
