So do I和So I do的区别和用法
一、So do I的用法
该结构主要用来说明前面所说的情况也同样适用于后面的人或物，意为“……也一样”。该结构中的助动词 do 根据前文的情况也可换成 is, am, are, was, were, does, did, can, could 等。如：
He passed the exam, and so did I.
=He passed the exam, and I passed the exam, too.
=Both he and I passed the exam.
=He and I both passed the exam.
他通过了考试，我也通过了考试。/ 他和我都通过了考试。
又如：
They went to the zoo yesterday. So did we. 他们昨天去了动物园，我们也去了。
但是如果前面所述情况为否定式，则用neither, nor引出倒装句(此时不能用so)。如：
He couldn't do it, and neither could she. 他做不了这事，她也做不了。
He never comes late. Nor do I. 他从不迟到，我也从不迟到。
二、So I do的用法
该结构主要用于加强语气，其意为“的确如此、确实如此”，表示后者赞同前者的话或意见，只是进一步强调并重复前句所述的内容。前后句的主语指的是同一个人或物。该结构中的助动词 do 根据前文的情况也可换成 is, am, are, was, were, does, did, can, could 等。如：
—He has done a good job. 他干得不错。
—So he has. 他的确干得不错。
—He will speak at the meeting tomorrow. 他明天将在会上发言。
—
So he will. 确实如此。
—He went to see his friend yesterday. 他昨天去看朋友了。
—So he did. 的确如此。
