this picture is believed 填空 painted by Turner A it was B to be C to being D to have been求详解
一个固定的句型：主语+be done + to do;意为：“据.主语,”
如：The boy is said to be honest.这孩子据说很诚实.这里用的是不定式的一般式,表明动作发生现在或与谓语同时发生.如果不定式的动作发生在谓语动作之前,就要用它的完成式,即：to have done.
The picture is believed to have been painted by Turner.画是被画的,所以用了被动式.而且动作发生在谓语之前,所以用了完成式.即不定式的完成被动式.

选 D。be believed to be 指“被认为是……”，由于是过去画的，使用过去完成时have been

选B
