In CAD and curve-fitting fields, we want to generate such rational cubic Bezier curve which is a unique curve passed given points and convenient to connect other curve segments with C1 connection. However, the method proposed in paper  can not meet above objective. in this paper, we propose a new method for generating a unique rational cubic Bezier curve which passed given points. The generated curve is with given tangent vectors at its two end points, and it is convenient to connect other curve segments with C1 connection. Also, some examples of curve generated by this method are given.
