Question

(2011·上海高考)Today we have chat rooms, text messaging, emailing ... but we seem ________ the art of communicating face­to­face.

A．losing                              B．to be losing

C．to be lost                           D．having lost

Answer

B

【解析】选B 考查非谓语动词作表语。句意：现在我们有聊天室，能传递文本信息，还可以发电子邮件……但是我们似乎正在失去面对面交流的技能。seem后通常用动词不定式，排除A和D两项；此处非谓语动词后有名词短语the art of communicating face­to­face作其宾语，所以排除C项(被动形式)，故选B。
