(单选题)
You can’t imagine what great trouble they have ______ the problem ______.
A.to solve; being talked about
B.solving; discussing
C.to solve; to talk about
D.solving; being discussed
参考答案:D
参考解析:
考查非谓语动词。句意:你无法想象他们解决正在讨论的这个问题有多困难。分析句子成分可知,what great trouble they have ______ the problem ______在句中充当宾语从句,在宾语从句中have trouble (in) doing sth.为固定搭配,意为“做……有麻烦”;第二个空为非谓语动词充当后置定语,由于problem与discuss之间为被动关系,表示“正在被讨论的”,强调动作正在进行,因此此处应使用现在分词的被动语态。故选D。
