回答：   gret doing 是后悔做过某事(说明这件事是已经做过了，发生过了）,      regret to do 是后悔去做某事（说明这件事还没发生，没做过）。
  2。这是现在完成时的被动结构be said  是据说的意思，后面跟了 to do 是动词在其后再接另一个动词的固定结构要加上to do，这是说这本书已经被翻译成了许多种外语语言。
  3。很明显without后面接的是一个被动结构，而without是个介词所以后面的be要加上ing形式。
  4。consider doing 是表示考虑做过了的事，consider to do是考虑去做某事。
  5。这里选can有“可以”和”应该“的意思，can 在大多说祁使句里都可以这样用，因为这样表达可以更委婉，口气更婉转。
