1.1 Rationale for Selecting the Theme选题的基本原理
哈利迪声称语言有三大纯理功能之经验:意识形态功能,人际功能和文本的函数(朱(& Yan施正荣清,2001)。对于人际功能,人们使用的语言与他人互动,建立并维持与他们的关系,影响他们的行为,来表达自己的观点,来引出或改变他们的。所以语言是用于建立和维持社交关系,确定社会角色,并且还把事情做完Halliday claims that language has three meta-functions: ideological function,interpersonal function and textual function (Zhu Yongsheng & Yan Shiqing, 2001). Asfor interpersonal function, people use language to interact with others, to establish andmaintain relations with them, to influence their behavior, to express their ownviewpoints and to elicit or change theirs. So language is used to establish and maintainsocial relations, to identify the social roles, and also to get things done. Fowler (1991)thinks that the interpersonal function is realized chiefly through the system of mood,modality and speech acts.However,https://www.51lunwen.org/yywxlw/ the research on interpersonal function was not fully developed withinSFL.

Lisa Carducci, a Canadian writer, doubted who wouldbenefit then? She suspected the Expo to be mostly a commercial event.Why does China always need to do things so big? What can ordinary people think ofthe country that in less than two years hosted not only the greatest Olympics in the world,the biggest National Day (60th anniversary) celebration and now the most expensive WorldExpo of all times, but also was rocked by a devastating Sichuan earthquake that left about80,000 people dead, the recent earthquake in Qinghai and suffered a terrible drought inSouth China…. the expensive Expo would have a negative impact on China's image, as Idiscovered recently, for not a small number of Westerners see it as a huge本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
