The major significance of this thesis is researching major characters’ mindsets and physical conditions when communicating, as well as relevant strategies to enhance communication effectiveness, with the help of AUM theory。 The analysis looks at the whole process of communication, which helps interlocutors to have a better picture of intercultural communication。 More specifically, what they can learn are from the preparation before interaction to the reaction to strangers at the end of a conversation。 

 I choose a film as example, for films are originated from life, and those about intercultural communication tend to reflect problems in a more visualized and detailed way。 The film A Grandson from America is an excellent sample, as the issues it reveals are mostly common in our daily life communication。 Therefore, they are more understandable to interlocutors, and they are interlocutors’ major concerns。 Additionally, this film reflects representative conflicts between Chinese and American culture in many aspects, like language and education, which are informative to interlocutors。 

1。2 Literature Review

1。2。1 Researches Related to the Practice of AUM theory

Researches on AUM theory hitherto mainly focus on intercultural adaptation of students or employees who are frequently exposed to an intercultural environment。 Gudykunst and Hammer (1988) combines intercultural adaptation with anxiety reduction theory。 Gudykunst(1998) put forward an training program and confirms that AUM theory can be applied in every stage of intercultural adaptation。 

Brandl and Neyer (2009) points out that dealing with unfamiliar information is critical to anxiety and uncertainty management of global virtual teams。 Their study shows that abilities of processing complicated information, tolerating ambiguities and knowing cultural differences influence how effective people adapt to new information。
