(单选题)

—Father, you promised!
—Well, ______. But it was you who didn’t keep your word first.

A.so was I

B.so did I

C.so I was

D.so I did

参考答案：D

参考解析：

考查so位于句首的倒装。句意：“父亲，你答应过我的！”“对，我答应了，但是是你先不遵守诺言的。”“so+助动词/情态动词/be动词+主语”意为“……也……”；“so +主语+助动词/情态动词/be动词”意为“……确实……”。根据句意可知，此处表示“我确实答应了”，且通过前半句的promised一词可知，本题的助动词为did。故选D。

知识点：

—Father, you promised!—Well, ______. But it was you who didn’t keep your word first.

—Father, you promised!
—Well, ______. But it was you who didn’t keep your word first.
