Abstract Pubic Service Advertisements, also known as PSAs, are messages in the public interest disseminated by the media without charge, with the objective of raising awareness and changing public attitudes and behavior towards  social issues。 Today, with the development of globalization and social economy, intercultural communications are becoming increasingly important。 Many of the issues concerned in PSAs are universal, but due to cultural differences, there are differences in understanding PSAs in specific countries。 This thesis analyzes the differences of two Chinese and American public service advertisements about non-smoking mainly from three aspects -- language, presentation and value orientation。 Then, this thesis focuses on the reasons accounting for those differences from the perspective of high and low context theory, aiming to reveal characteristics of different contextual cultures, enhance better understandings of the impact of cultural differences on PSAs, avoid cultural conflicts and promote cross-cultural communications。94117
