| Before Chomsky's, the theory of the description is that there is irrelevant between passive sentence and active sentence, there is irrelevant in the language syntax and grammer. However, Chomsky not only recognized the link between passive sentence and active sentence, but also admitted that the passive sentence was transformed by corresponding active form.In Chomsky's view, the relations between passive sentence and active sentence are transforming relations. He used classical sites theory to simulate this transformation process and he made a conclusion that the forming of passive sentence was because the verbs had been changed passive forms. So the verbs are not complete verbs, and have not the ability. In order to be assigned sites, the nouns must be shifted from the location of complement to the place of subject. And such a surface structure of the passive sentence is being. A theory to the classical theoretical for the theory of Sites has become very mainstream views.However, we believe that there is a discreponcy between the fact and the process of simulation, we have expanded lattice filters under the new theoretical simulation of a passive sentence transformation process. And we believe that the transformation of a passive sentence is the result of choice topic and expanded grid filter, and also because the deep structure of a selected topic in the unnatural has been shifted, the verbs has been changed forcely, so a passive sentence is formed. |
