A. I ought to

B. So I ought

C. So it was

D. So I did

答案：

A. I ought to

B. So I ought

C. So it was

(答案→)D. So I did

解析：考查特殊结构。“So+助动词/情态动词/be动词+另外一主语”表示前面的肯定情况适用于另外一个人。“neither/noe+助动词/情态动词/be动词+另外一主语” 表示前面的否定情况适用于另外一个人。“So+同一主语+助动词/情态动词/be动词”表示前面的情况属实。句意：—你本应该给他一些建议的。—我的确给了建议，但是谁又会在乎我的请求。故D正确。
