  We compactify the M-theory proposed by Horava and Witten on a Calabi-Yau
manifold with boundary $S_1/Z_2$. A no-scale-like K\"ahler potential, the
superpotential, and the gauge kinetic function are obtained in this
4-dimensional $E_6\times E_8$ model. We also study the general phenomenological
consequences of the resulting M-theory-inspired model, which may include very
light gravitinos, axions and axinos.
