Abstract: Keeping $N=1$ supersymmetry in 4 dimensions and in the leading order, we discuss the various orbifold compactifications of M theory suggested by Horava and Witten on ${T}^{6}{/Z}_{3},$ ${T}^{6}{/Z}_{6},$ ${T}^{6}{/Z}_{12},$ and the compactification by keeping singlets under $\mathrm{SU}(2)\ifmmode\times\else\texttimes\fi{}U(1)$ symmetry, then the compactification on ${S}^{1}{/Z}_{2}.$ We also discuss the next to leading order K\"ahler potential, superpotential, and gauge kinetic function in the ${Z}_{12}$ case. In addition, we calculate the SUSY breaking soft terms and find out that the universality of the scalar masses will be violated, but the violation might be very small.
