摘要：This paper investigates the frequency of occurrence of the passive and impersonal structures at two different periods of Persian literature, namely, classic and modern literature to decide on the tendency of their language use. To do so, a number of texts from the two periods were selected and analyzed. The quantitative study of the data shows that the occurrence of the impersonal structure is much more frequent in both classic and modern texts. The results indicated that Persian writers tend to use impersonal structures rather than the passive voice is not used. The findings also indicated that the passive voice is not so common in Persian.
