——He ought ot have been warned of the danger.
—— , but he wouldn’t listen to me.
A. yes, he ought to
B. So he was
C. So was he
D. So it was with him

A. yes, he ought to(答案→)B. So he wasC. So was heD. So it was with him解析：考查“so +主语+助动词”的用法。强调“我的确警告他了，但是他没有听从我的建议。”选项A最具有迷惑性，学生容易受思维定势的影响。“ought to have done sth”表示“该做的事而没有做”，注意上下文的联系。
