问题 The Bunsen Burner is so named because it is thought______by Robert Bunsen.

选项 A、to be invented
B、having been invented
C、invented
D、to have been invented

答案D

解析 be thought to do为固定搭配，意为“被认为”，而且本句动词不定式中invent所表示的动作发生在主句谓语is named所表示的动作之前，而且和The Bunsen Burner一是逻辑上的动宾关系，所以要用不定式的完成被动式，即“to have been+过去分词”的形式。故选D。
