Rebecca was unhappy for _____ the first chance to go abroad.
A．not having been given
B．not having given
C．not giving
D．having been given
答案：A
题目分析：考查动名词：句意：吕蓓卡对于没有机会出国很不高兴。介词for后面接动名词，因为是先没有机会，然后才感到不高兴，所以是动名词的完成式，根据句意应该是：not having been done是动名词的完成被动式的否定形式，表示动作发生在谓语动作前。选A。
点评：动名词的完成式与英语的完成时态有些关联。大家知道，英语的现在完成时态由“have+过去分词”构成，而动名词的完成式就是将“have+过去分词”中的助动词have改为动名词即可，动名词的完成式主要表示发生在谓语动作之前的动作或状态。
