Taking the acquisition of degree adverbs as an example, this paper attempts to explore the process and result of acquisition of degree adverbs under the framework of input and output theory of Krashen and Swain. In this paper, the empirical adverbs of degree adverbs are applied to the study of mother tongue learners and foreign students to further reveal the acquisition process of adverbs of degree under the input and output mechanisms.
