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

Question

如题所述

Answer 1

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。

Answer 2

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

Answer 3

选B
