Owing to the lack of language knowledge or cultural background of the target language,foreign language learners tend to apply the pragmatic rules and cultural standard of their native language to the target language,which will unavoidably lead to the failure in communication.

On the basis of the conclusions of some pragmatic rules of English personal pronouns and the statistics of English personal pronouns in want advertisements, this paper arrives at the context-dependent features of English personal pronouns.

Long-winded attribute,confused logic level,non-Chinese usage rule of attribute and missing constinuent often appear in Japanese students translating the complicated Japanese substantive modlifier into Chinese.

This paper proposes an algorithm combining statistics with rules,called the priority merger algorithm,which merges phrases by calculating the relationship of words,checks phrases by using phrase rules and a semantic dictionary in grammar and semantics,and recognizes Chinese phrases by the means of hierarchic analysis.

Lots of semantic rules are obtained from the experiments, and are used to sense disambiguation.

And finding the correct data dependency is also based on the semantic rules contained in data.
