Vocabulary is an important part of modern Chinese, in which synonyms are difficult and important in teaching Chinese as a foreign language. The “to pass ” and “through” are commonly used words in modern Chinese. There are many similarities and differences in the parts of speech and meaning of this group of words. In the HSK Dynamic Composition Corpus, the errors of “to pass ” and “through” mainly focus on mixing, omission and addition. The main reasons for the errors are negative transfer of mother tongue, over-generalization of target language knowledge and avoid strategies.
