问题描述：
What is done can’t be ____.A) done B) undone C) undo D) undid
答
选择B。
覆水难收
“What is done cannot be undone。”中“done”是“do”的过去式，“已经完成”的意思。“undone”是否定，“not”也是否定，双重否定表肯定。“What is done cannot be undone。”即“What is done is done 。”。意思是“做过了就是做过了。”也就是“覆水难收”。
答
B
答
B) undone
undo表示撤回,返回到没做的状态.do的被动式是done,同理undo的被动形式是undone.
句子的意思是已经做了的事情是不能被撤回的~也就是说“木已成舟,生米煮成熟饭.”
答
B) undone
What is done can't be done.
木已成舟，生米煮成熟饭。
