This problem is said _____ three times. A．having discussed B．to have been discussed C．having been discussed D．to have discussed

Answer 1

B

试题分析：考查句型：Sb/Sth is said to have done,某人某物据说已经做了…，因为problem和discuss是被动关系，用不定式完成式的被动，句意是：这个问题据说已经讨论了三次了。选B。 点评：Sb/Sth is said to have done表示不定式的动作在句子的谓语动词之前发生，如果是将要发生就用Sb/Sth is said to do.
