C. rising; handled
D. risen; handling
网友回答
A. arisen; handling
(答案→)B. arising; handled
C. rising; handled
D. risen; handling
解析:句意:由于缺乏交流误解不断出现,如果不及时合理地处理,这些误解也许会导致更严重的问题。arise出现;rise上升;handle处理。这里整个句子的谓语动词是may lead,第一空是非谓语动词arise与misunderstandings之间是主动关系,第二空unless后是省略句,完整的是unless they are handled properly,
故选B。
