Aspectual phenomena in French constitute a research domain which interests permanently French scholars and divides them all the time. Based on the previous research, this paper classifies aspectual phenomena which are distributed on different language levels in French, i.e. grammatical level, lexical level and syntactical level, and examines the linguistic forms, aspectual significations as well as characteristics of these phenomena, in order to prove that they are different parts of aspectual system in French. These parts have not only semantic connections among them, but also restrictions and influences between each other, forming a stratified, effective and interactional aspectual system.
