非谓语中的having done是现在分词的完成式，它表示主动的动作，并且动作发生在谓语动词之前，常常作状语来修饰动词。done过去分词无论作状语或作定语，都表示被动的动作，也可以表示已经完成的动作。  having done例句 Having done these things, he went on again. 做完这些事，他又继续往前走。 Having done quite well in the important exam, he came back home, relaxed and smiling. 他在这场重要的考试中做得很好，他放松地回到家，面带微笑。 It would be rash to try an exam like BEC Higher without having done any preparation at all, even if your English is very good. 即使你的英语很好，如果你没有做任何准备就参加 BEC 高级考试，那也太草率了。 You can congratulate yourself on having done an excellent job. 你应该为你出色的工作感到自豪。 Having done that,she now could rest. 做完了这些事，现在她可以安息了。 He felt ashamed of having done so little. 他为自己干得太少而感到羞愧。 (责任编辑：admin) |
