This paper revises ‘Mid–way conjunction(Park (2005a) and coordination by conjoin–α operation (Ihm(2007))’ approach to account for the derivation of RNR construction. A big difference is that while the previous approach assumes top-down system, this paper adapts the bottom-up one. Furthermore, this paper investigates the scope phenomena of a shared material of RNR construction. (Bachrach and Katzir, 2006) tried to explain the scope phenomena of a shared material of the construction on the basis complete domain idea. However, the idea cannot accommodate a shared material many QP under negation and so it faces a challenge. On the other hand, when a shared material many QP under negation receive focus in RNR construction, it can take a wide scope over negation. .
