网友回答
A. shouldn’t have enjoyed
B. needn’t have enjoyed
C. wouldn’t have enjoyed
(答案→)D. couldn’t have enjoyed
解析：选D。题干的意思是：“我从未玩得更开心过——这是完美的一天。”shouldn’t have done表示“本不应该做而事实上已经做了”；needn’t have done表示“本没有必要做而事实上已经做了”；wouldn’t have done用于虚拟语气；couldn’t 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。
