Foreign language learning is one of the important tasks of school students, and it is also an
indispensable part of the learning of some social people. Mastering a foreign language is the need of
social development, but most people get twice the result with half the effort. In the field of vocabulary, the
acquisition level is high. However, the learning effect of syntactic structure is not satisfactory. This paper
systematically summarizes the main influencing factors and laws of second language syntactic processing
by combing the relevant research on syntactic processing at home and abroad. Language background,
acquisition age, way of language acquisition, language proficiency, language input, working memory and
other cognitive levels, learners’ motivation and attitude, these factors will affect the learning effect of
learners’ syntactic structure.
