Seen from the semantic perspective as the subject is divided into four types; as the object is divided into five types. Subject statements are generally used in Oracle and prepare conditions for the production of passive sentences. In relational object sentences, adding the relational preposition “于” between verbs and objects is a sign that Oracle is perfecting its grammatical form. In the presence of object sentences The existence of the verb “有” is closely related to the existence of similar pronoun in the subject sentence.
