Firstly, we analyze animate noun from three semantic features of control; secondly, we compare the power of person, organization and location in order to check out their animacy; thirdly, using VP-internal Subject Hypothesis in Transformational and Generative Grammar, we investigate Chinese, Kachin and Hani of Tibeto-Burman languages and give out the animacy hierarchy of semantic roles; fourthly, we discuss the animacy of personal pronoun, referential pronoun, proper noun, general noun and abstract noun; fifthly, topic and subjectivity pay attention to the variation of animacy of noun in the paragraph from pragmatic and cognitive points of view respectively; sixthly, we compare the numerical representation of noun in Chinese and Tibetan and other Tibeto-Burman languages. The conclusion is drawn on the relationship between number and animacy; lastly, the influence of popularity on animacy is pointed out. The fifth part includes conclusion and questions leaving behind.
