"Every possible means ____________. However, nothing can __________ him from dying of lung cancer.
A. has tried; stop
B. have been tried; keep
C. has been tried; prevent
D. have been tried; stop"

Answer 1

答案C
means作名词，表示“方法”“手段”是单复数同形的词。当all means作主语时，谓语动词应该用复数形式；every means作主语时谓语动词应该用单数形式。当表示“阻止某人做某事”时可以说stop/prevent sb.(from) doing sth. 但keep sb. from doing sth. 表示“阻止某人做某事”时，from不能省略。
