A. Without being invited

B. Not be invited

C. Be not invited

D. Not having been invited

答案：

A. Without being invited

B. Not be invited

C. Be not invited

(答案→)D. Not having been invited

解析：考查非谓语动词。句意：当时什么让她如此沮丧？她一直在哭。——没有被邀请参加舞会。下文省略了谓语动词，只保留主语。动名词做主语表示抽象动作。如果动作发生在谓语动词之前，则要用完成时态的动名词。动名词的逻辑主语她是动作对象，故用被动语态。选D。
