enjoyedDcouldnt have enjoyed【解析】句意：我从未玩得更开心过这是完美的一天。shouldnt have done表示“本不应该做而事实上已经做了”；neednt have done表示“本没有必要做而事实上已经做了”；wouldnt have done用于虚拟语气；couldnt have done表示“不可能做过”。此处用not和比较级连用表达最高级的含义，意为“从未比这更高兴过”。所以正确答案为D项。【答案】D句型转换Mothers love is the most precious in the world._He studies(the)hardest in his class._【答案】Nothing is more precious than mothers love
