Good morning, all appraiser committee members. I am **** and my supervisor is ***. With her constant encouragement and guidance, I have finished my paper. Now, it is the show time. I will present my efforts to you and welcome any correction. The title of my paper is On Transformation of Parts of Speech in Translation.

I choose this as my topic due to the following reasons. Different languages have different standards to distinguish parts of speech. Each language has its own special structure. And there are no equivalent parts of speech between different languages. In order to make the target version more idiomatic and standard, the transformation of parts of speech is always used by translators.

So the transformation of parts of speech is playing a more important role in English to Chinese based on different characteristics of English and Chinese. For the above facts, I select the subject of“On Transformation of parts of speech”as the title of my paper.

I hope by studying this topic we can know the importance of the transformation of parts of speech in English to Chinese translation. Through transformation, we can get the better version and improve the translation skills.

The way of thinking and expressing is quite different between Chinese and English. English is a kind of static languages which tends to use more nouns. While Chinese is a dynamic one in which verbs are often used.

So when we make translation in English to Chinese, we should know this point and shift the parts of speech.

Next, it is an outline of my paper. In the main part of this paper, I divide it into five parts.

Part one presents an introduction to the basic concepts of parts of speech and transformation.

Part two discusses the definition of translation and emphasizes the importance of transformation of parts of speech in the course of translation.

Part three gives four basic ways of transformation of parts of speech through illustrative examples. There are transformed English words into Chinese verbs, nouns, adjectives and adverbs.

Part four presents some problems about transformation and gives some advise to solve the problems.

Part five draws some conclusions that transformation between parts of speech is necessary for us to achieve good translation. It is demonstrated that we can have a good master of transformation and improve the translation. In addition, we must continuously study and explore in all kinds of translation practices. OK! That is all. Thank you! Please ask questions。

Good morning,

Distinguished professors and teachers, ladies and gentlemen, thank you for attending the oral defense. (或Welcome to attend the oral defense.) ： I am XX. First and foremost, I would like to express my sincere grat-itude to my supervisor, professorXX, for his intellectual guidance, invaluable instructions and comments on my thesis. It is with his valuable assistance that I have finally accomplished this thesis.

My topic is On the tragedy figures at historical turning points(Comparison of KongYiji and Rip Van )The whole thesis consists of 6 parts.

The first part will give a brief introduction of the negative, evasive and conservative attitudes of Kong and Rip as well as the topic’s significance in the real society. And the second part is going to analyze the figures’ background to show the historical necessity of the tragedies.

In the third part, the tragic heroes’ failing in the character according to their living environment will be further discussed and the fourth part is to talk about their different tendency of dispositions and behaviors in the society.

Then the author will dig into the root causes of the tragedies in the fifth part, and sum up the whole paper to reveal the ideological weak points of the two countries separately in the last part.

Thank you!

next , i will present it to you. here is an outline of my presentation. they are literature review, gothic tradition , the gothic style in the story and the causes of the gothic style .

this paper consists of six parts. part one presents an introduction to the author william faulkner and a rose for emily by pointing out the purpose and significance of this study. part two is literature review which introduces the relevant research about this novel at home and abroad and then points out the theoretical basis and methods. part three gives a timeline of the gothic tradition in literature and explains the main characteristics of gothic works. part four explains the three aspects of the gothic style in the novel,that is, the death theme, grotesque characters and mystic atmosphere. part five then explains in detail the causes of the gothic style in this novel: patriarchal oppression, the myth of southern ladyhood and emily s attitude towards love. finally, in the conclusion, the author summarizes the previous parts and emphasizes the significance of the argument of the thesis again.

ok, that"s all. now you may raise your questions ! i am ready! thank you !

today, the title of my paper is on the network novels. in recent years, the network literature is developing rapidly. network novel is one of the fast of them. in the middle schools, high schools and even universities, there is no lack of network novels" addicts. for the above facts, i select the subject of on the network novels as the title of my paper.

the last part, the forecast. looking from the internal strength pattern, the outstanding writers in our country mainly hold one kind of critique and the pessimistic manner to the network novels at present. if each big literature website enlarges their own supervision, the vulgar works, the pornography and bad works like those things, meanwhile hanker for new person s new article as well as depth ones, the network novels can be accepted by more people.

not a low-level novel but a kind of enjoyment.

The topic of my thesis is 《Angela carter to mythology research - the female archetype in “new eve passion”, for example》. I choose this as my topic due to the following reasons.

Angela Carter (1940-1992) is an outstanding feminist writer whose influence on Britishwomen's writing was “pivotal in this opening and transformation” [“23]. The year 2014 represents the 22”^ anniversary of Angela Carter's death. In those twenty-two years, her works have been widely taught internationally and brought about much critical debate. In a survey conducted by Cristina Bacchilega and Danielle M. Roemer [2],Carter is one of the most commonly taught women writers on North American programs. She has endowed us with an amazingly large number of legacies in her comparatively limited life, setting foot in various fields such as novels,short stories,children stories, dramas, non-fictions and so on. The acute observations with great insights,as well as the devastating wit and poignant mockery in Carter's works have made her stand out as an iconic figure in English literature. Many scholars and critics have devoted themselves to the research on Angela Carter from many perspectives,including gothic, magic realism, feminism,post-modernism and so on. As a prolific writer who is always ready to blur the boundaries between different genres, Carter has left us a wonderful world to delve into.

With the emergence of western women's movement as well as the development of feminist criticism in the 1960s,the feminist approach has become a potent weapon for those who are concerned with the emancipation and legal rights of women. Though women's social status has considerably improved due to the contribution made by countless predecessors,the fundamental problem still lingers on. Carter, with her versatile and avant-garde reputation, is best known as a feminist writer. Concerning the dilemmas and predicaments faced by women nowadays,it is very necessary for us to probe into her insightful and penetrating reflections on femininity as well as the relationship between two genders. The Passion of New Eve, as one of Carter's most representative works, is of great value in the research of her feminist thoughts and propositions.

Next, is my paper outline. In the main part of this article, I put it into five parts.

Chapter one is an introduction to the thesis, covering the research background, theobjective and significance as well as the organization of the thesis.

Chapter two presents a broad picture of Angela Carter's life and her works, as well as the background information about The Passion of New Eve. It also reviews previous studies on Angela Carter and her works at home and abroad, summarizing achievements in the past and pointing out new directions in the future.

Chapter three conducts a retrospective study on feminism and archetypal criticism. The author attempts to work out the origin and development of feminism, demonstrating the important role feminism plays in Carter's life. Then is the history of archetypal criticism,as well as those classic female archetypes in mythology. Regarding those fossilized and monotonous images as impediments to women's freedom and liberation,Carter endeavors to shatter them in her demythologizing strategy and appeals for a rational attitude toward heterosexual relationship.

Chapter four is the main body of the thesis. Through an in-depth analysis on The Passion of New Eve,it demonstrates Carter's demythologizing of “The Temptress,,,”Mother Goddess“and ”Eve“ respectively in the text. Leilah,the embodiment of Delilah,the famous temptress in the Bible,cannot escape the fate of being objectified by men and herself. By exposing”temptresses“ as mere victims rather than symbols of viciousness. Carter condemns the oppression and exploitation of women in a patriarchal society. ”Mother“ in Beulah serves as a severe satire on those mother goddesses in mythology. Carter smashes the legend by revealing the surgically-made essence of mother and the patriarchal values lurking behind her alleged matriarchal kingdom, warning against the peril and impracticality of extremist her most convincing example goes to Eve, the most important female character in the Bible, Her transformative journey from a chauvinist to a real woman in the story illustrates that gender, rather than a hereditary feature, is the result of social influence and unremitting imitations. Carter concludes the story with proposing ”androgyny“ as a solution to the current problems,implying that mutual respect and understanding is the only way to achieve the harmony between the two genders.

Chapter five comes to a general conclusion, summarizing the limitations of the theses as well as some suggestions for further study.

OK! That is all. Thank you! Please ask questions.
