All possible means ______. However, nothing can _____ his wife dying of lung cancer. A．has tried; stop B．have tried; keep C．have been tried; prevent D．has been tried; stop

Answer 1

C

名词用法以及动词用法。Means方法，是一个单复数同名名词，前面有all说明本句中的means是复数，谓语动词用复数形式且应该使用被动。Prevent sb from doing sth阻止某人做某事。句意：所有可能的方法都已经被尝试过了。然而，没有什么能阻止她的妻子死于癌症。
