In her article Ewa Ciszewska attempted to present the retrospective value (summary or synthesis) of the future perfect tense (futur anterieur). Futur anterieur is often used in press articles for underlining peculiar nature of an event from the past and for summarizing it, e.g. L'annee 2001 aura ete fatale pour l'economie mondiale. An analysis of the context makes it possible to indicate the elements which allow the reader to choose the correct interpretation of the futur anterieur tense. These elements comprise the expressions like: il aura fallu x temps pour..., il aura suffi de... pour..., summarizing expressions: au total, au final, en definitive, adversative phrases: en revache, neanmoins, pourtant and the adverbs jamais and rarement when they appear at the beginning of a sentence. In such utterances one can usually find continuative verbs {etre, durer, valoir) which are used with adverbials of time, thus indicating certain segments of time.
