Question

(2013·龙岩一模)—________ so many countries, you must be able to speak several different languages.
—I wish I could, but English is the only one I can speak.

A．Visiting	B．To visit
C．To have visited	D．Having visited

Answer 1

D

选D　考查非谓语动词。分析句子结构可知，句中已有谓语动词，故空处应用非谓语动词形式；且visit与you之间是逻辑上的主动关系，故应用动词的­ing形式。根据语境可知，空处的动作发生在谓语动词之前，故用动词的­ing形式的完成式。
