Based on a homogeneous second order linear differential equation with variable coefficient,a generalized (G'/G) -expansion method and its algorithm are proposed to seek exact solutions of nonlinear evolution equations.Being concise and straightforward,the method is applied to the Whitham-Broer-Kaup-Like equations.As a result,many new non-travelling wave solutions are obtained,which contain the hyperbolic function solutions,the trigonometric function solutions and the rational solutions,and they are all nonsingular at some points.This method can be used for many other nonlinear evolution equations in mathematical physics.
