Let R be a commutative domain with 1. In this paper, 1-w-cotorsion modules and strongly w_-flat modules are introduced and studied. It is shown that an integral domain R is a PVMD if and only if 1-w-cotorsion R-modules are injective if and only if all 1-w-cotorsion R-modules are w-FP-injective. And we show that all w_-Matlis cotorsion R-modules are w-cotorsion if and only if F_w= SF_w_ if and only if R{x} is an almost perfect domain.
