| In this paper,the HSK corpus is used as the source of corpus,and an exhaustive search is conducted to find out different types of object missions in prepositional phrases,focusing on the general characteristics of words that are prone to error.Then,we analyzed the error statistics from the perspective of the level and country of international students,and analyzed the causes of the errors.The research in this paper can play a certain reference role in teaching bingo,but due to the limited number of collected corpus compositions and their early age,the findings of the study still need to be verified by the corpus in recent years,and future studies can further supplement the corpus in recent years,which may bring more findings. |
