An Analysis of Formation and Use of Impersonal Sentences in French

French impersonal sentences consist of pure impersonal verbs, relative impersonal verbs and impersonal verbs borrowed from personal verbs. In general, the neuter pronoun il in impersonal sentences only functions as the formal subject, and the real subject is the noun, infinitive or clause following the verb, with the verb in the third-person singular form. The thesis will illustrate with examples the formation and uses of French impersonal verbs and sentences in the following four aspects, namely, impersonal verbs, impersonal sentences with some personal verbs, impersonal sentences with some acting verbs as well as semi-impersonal sentences.
