So did we 这句话是倒装句吗?

So do sb:
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.他通过了考试,我也通过了考试.
●He likes singing .So do I.他喜欢游泳,我也是.
●You are young and so am I.你年轻,我也年轻.
●I like watching TV and so did my sister.我喜欢看电视,我妹妹也喜欢.
●Tom can speak Chinese.So can Linda.汤姆会说汉语,琳达也会.
●If you go to the cinema tonight,so shall I.假如今晚你去看电影,我也去.
●—The students have gone to the park.同学们都去公园了.
—So has Miss Wang.王老师也去了.
●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.
●Lucy didn't finish her homework ,nor did Lily.露西没有完成作业,莉莉也没有.
●I am not wrong ,neither are you.我没错,你也没错.
