句子主语需要动名词，分词having had一般用作状语 我想知道动名词的完成式 having done能不能做主语？？？？？？有的有可以 有的说不可以？来个专业点的哦 可以 having killed bill made tom a murderer. 但是这个动作表示已经做了，你这题不是这样。 说可以用动名词完成时做主语的看2. . 2.herry doesn';t seem like the same person. ______so much in the war has made him more thoughful a.for him to see b.his seeing c.having seen d.to have seen那这个怎么算？？ b.his seeing c.having seen 这两个答案都是对的，你不是想玩我吧 故意出这种题？ 我相信你更相信练习册答案，而不相信我...
