  We discuss composite representations of new supersymmetry (SUSY) algebra
under nonlinear (NL) SUSY transformations in curved space-time from the
viewpoint of nonlinear supersymmetric general relativity (NLSUSY GR)/ SGM
scenario. We show in the linearization of NLSUSY how various basic fields in
linear SUSY theories/supergravity are expressed as functionals in terms of a
vierbein and Nambu-Goldstone fermion fundamental fields in NLSUSY GR.
