This paper attempts to deal with a contrast in sloppy reading found in some VP-ellipsis contexts from English. This reading is available if another VP-ellipsis applied in the preceding environment; it is unavailable if not. The purpose of this paper is to account for this contrast by exploring an alternative way to previous approaches such as the proform analysis by Schwarz(2000) and the LF structure analysis by Tomioka(2008). Despite some merits of these analyses, they are shown to have some difficulties in resolving the VP-ellipsis gaps. I then propose a new analysis in which some positive elements factored out of the two existing analyses are reshaped and incorporated more adequately in terms of focus feature percolation and inheritance.
