问题描述:

Mom asked Tony to make his bed after he got up.______ A.So did Tony B.So Tony did C.Tony did so
应选哪一个?
这句话我理解为:妈妈要求Tony起床后整理床铺,Tony 这样做了。我觉得B和C都可以表达Tony 这样做了。为什么B选项不能选?不是有个句型(So+主语+助动词/情态动词/be动词)表示“的确如此”吗?C选项中的so我理解为代词(意思是“这样,如此”),你理解的So好象是"所以,因此”的意思,如果是作为这个意思,so的位置不对呀?

c 的意思是“汤姆照做了”,这句话的内涵就是这样,B表示“的确如此”,不符合题意.
