In the eighth chapter of Translation Behavior and Cross-cultural Communication, the author adopts the viewpoint of functionalism translation theory, regards translation as cross-cultural communication behavior, takes Vermeer's teleology of German functionalism school as the core, and verifies the effectiveness of functionalism theory through a large number of concrete examples, confirming the fact that translation is diverse in the era of globalization;
On this basis, it is explained from different aspects that translation is a decision-making behavior made after a complex comprehensive judgment of relevant situations. The translation methods of proper nouns, the translator's freedom to deal with implicit and explicit phenomena, and the translation evaluation model have answered important topics in translation theory, such as what is the diversity of translation, how the translator makes judgments, and what factors are related to translation.
