【题目】____regular training in nursing, she could hardly cope with the work at first.
A. Not received B. Since receiving
C. Having not received D. Not having received
在线课程【答案】D
【解析】考查非谓语动词。句中receive和主语she是主谓关系，用doing形式。且receive发生在主句谓语动词之前，用having received，not放在非谓语动词前。句意：由于没有接受过正规的护理培训，起初她几乎无法应付这份工作。故选D。
