In　this　paper,　we　consider　a　nonautonomous　predator-prey　model　with　Holling　type　II　schemes　and　a　prey　refuge.　By　applying　the　comparison　theorem　of　differential　equations　and　constructing　a　suitable　Lyapunov　function,　sufficient　conditions　that　guarantee　the　permanence　and　global　stability　of　the　system　are　obtained.　By　applying　the　oscillation　theory　and　the　comparison　theorem　of　differential　equations,　a　set　of　sufficient　conditions　that　guarantee　the　extinction　of　the　predator　of　the　system　is　obtained.
