This paper analyzes the cultural elements of China's four traditional festivals from the perspective of the Theory of Cultural Functions, which presents in detail the forming of traditional festivals, varied festival traditions and good expectations held by people toward lives. This paper is also designed with the aim to further exert the functions of traditional Chinese festivals, which as a result, will contribute to the preservation of national characters and the inheritance of national spirits.
Swain's(1985) "Output Hypothesis"maintains that output performsthree functions,namely,the"noticing/triggering function",the"hypothesis-testing"function,and the " metalinguistic" function.Based on the " Noticing Hypothesis",this study aims to investigate the role of the noticing function of output in second language acquisition.The major findings of this research are summarized as follows:1) when composing,the learner could notice linguistic problems in their ineterlanguaeamong which problems arising from vocabulary and sentence were the most prominent.2) with more attention paid to vocabulary,the learner could notice linguistic forms of various aspects when comparing their original text to the modelsof writing.And they could partially incorporate what they hadnoticed in models into their subsequent revision.3) through models of writing learning,the EG learners performed better than the CG learnersin error correction in Composition2,which proves that output with subsequent input learning has superiority over output without relevant input followed in facilitatingthe acquisition of accuracy of linguistic forms.
