题目内容
【题目】Three days after the aircraft went missing, an international effort ________ ships and planes hasn't found any wreckage, ________ growing frustration for the families of the 239 people on board.
A. involved; causingB. to involve; caused
C. involving; causingD. involving; having caused
【答案】C
【解析】
试题分析:考查非谓语动词。句意:飞机失踪三天后,包括船只和飞机的国际援助也没找到残骸,增加了机上239人家庭的悲伤情绪。第一空ships and planes和an international effort是主动关系,所以用现在分词作后置定语;第二空逻辑主语是前面一句话的内容,与cause是主动关系,故用现在分词作伴随状语,故选C项。
