At present, there is no analysis of the errors in the acquisition of Chinese prepositions"Duì(to)" and "Gěi(for)"by Uzbek speakers in China. There is no "preposition" classification in Uzbek, and most of them correspond to Chinese prepositions as "affixes or auxiliaries".Based on the theory of "error analysis", this paper selects the Chinese prepositions "Duì(to)" and "Gěi(for)" to investigate the Uzbek students, analyze the causes of their errors, and put forward relevant teaching strategies.
