This paper aims to overcome some problems of scope ambiguity in DRT by Kamp & Reyle(1993), to decide four types of the meanings from an indefinites within the scope of universal quantifier and to present the DRSs corresponding to them. In particular, the DRS to specificity is different from the one by Kamp & Reyle(1993) and the DRSs to a generic moaning and to a universal one will be presented as well. The Proposal in this paper is based on the conclusion that more than four kinds of meanings can result from an indefinite M) within the scope of universal quantifier, regardless of any syntactic structure and any kind of a movement rule like quantifier-raising.
