Question

Leonardo da Vinci (1452-1519) ____ birds kept in cages in order to have the pleasure of setting them free.

A．is said to be buying	B．is said to have bought
C．had said to buy	D．has sad to have bought

Answer 1

B

考察句型结构，be said to do/to have done结构，意为据说，have done表示动作已经发生，因为达芬奇买笼子里的鸟发生在过去，动作已经发生，所以选择好B。
