Since 1990s, a great number of excellent cartoon movies have been produced .For example the world famous Shrek, Garfield, and so on. Although the contents of these cartoon movies are different, these cartoon movies are one of the approaches for people to know American society and its citizens. Therefore, this study shows not only the background and the main works of American cartoon movies but also the different aspects of American social culture - politics, economy, education and values. In every aspect, some explanations of the affiliation between American society and its cartoon movies have been brought forward.展开更多
