Chinese is an isolated language. Prepositions are used to express grammatical meanings. Generally, prepositional phrases are composed of nouns. The whole prepositional phrases are mostly used as adverbials in front of sentence predicates. Uzbek is a cohesive language,affixes and auxiliaries are abundant. Affixes are placed after body parts of speech to express grammatical meanings such as location, time and object. There is no "preposition" classification in Uzbek, and most of them correspond to Chinese prepositions as "affixes or auxiliaries". This paper adopts four steps of "contrastive analysis". Firstly, it describes the Chinese prepositions "Gěi(for/to), Duì(to)" and its corresponding Uzbek affixes or auxiliaries. Secondly, the Chinese prepositions "Gěi(for/to), Duì(to)" are compared with the corresponding Uzbek affixes or auxiliaries. Finally, based on the results of contrastive analysis, this paper predicts the transfer in the acquisition of Chinese prepositions "Gěi(for/to), Duì(to)" by Uzbek speakers.
