问题 The Bunsen burner is so named because it is thought______by Robert Bunsen, who was German by birth.

选项 A、to have been invented
B、to be invented
C、of being invented
D、as being invented

答案 A

解析 to have been invented是不定式作主语burner的补足语，其相互关系是被动，相当于the burner was invented，所以用不定式的被动式，完成式表明invent这一情况已经发生。如果选C或D，应该是…is thought of as…"被认为是……"。
