In this paper, we study the following forced second-order nonlinear differential equation with damping (r(t)k1(x(t), x´(t)))´ + p(t)k2(x(t), x´(t))k1(x(t), x´(t)) + q(t)f(x(t))=e(t) and establish several sufficient conditions for this equation to be oscillatory. In the meanwhile, we point out the mistake in the related articles.
