As a global hallmark event, the Olympics, with their enormous scale, universal attraction for the media and tremendous political significance, have increasingly drawn attention from the researchers. It is obvious that Beijing has been greatly impacted by the 2008 Olympic Games as the host. The event aroused close attention of researchers, especially the problem how the Olympic stadiums and facilities can be utilized after Olympic Games. The paper employed 3 methods to conduct a survey, that is, sending questionnaires to tourists, in- terviewing with government officers, and collecting information about former Olympic Parks from Intemet and lit- eratures. The utilization of former Olympic Parks after Games was summarized and some experiences were refined. Besides, 3 main bodies including government, business operators and visitors which formed basic driving forces to influence the park's use were analyzed. At the same time, the paper believes that 3 topics affect the park's utilization involving 'prepare to use', ~how to use it' and ~how to manage it', and Beijing Olympic Park can also follow that thinking and reference in the ft^her practices. Based on it, suggestions are given that Beijing Olympic Park can be planned spatially from 3 layers, the point, line and area, based on their function and infrastructure in the Games, and the area would be shaped as a new urban center with multi-functions while Mega-events and sport events are still the main content of the park.展开更多
This paper analyzes the effect of rhetorical devices, such as irony, sarcasm, parody, hyperbole, pun, antonomasia, etc., in dialogues of the American TV series The Big Bang Theory (2007) with an aim to help improve ...This paper analyzes the effect of rhetorical devices, such as irony, sarcasm, parody, hyperbole, pun, antonomasia, etc., in dialogues of the American TV series The Big Bang Theory (2007) with an aim to help improve English learners' awareness and appreciation of rhetorical means in English-based literary works. Instances are cited with the use of such rhetoric means in the dialogue transcriptions. It is discovered that integrated use of a variety of rhetorical devices is a significant means for vivid and impressive characterization in literature. Such an analysis is a rewarding journey on either an academic or entertainment basis, and a process of discovery and learning that may particularly be well-received with EFL (English as a Foreign Language) learners展开更多
