I didn't manage to get into town this morning.要求是用managedto，这里的managed是过去式吗？我以为managedto就是一个短语。not manage to do sth是managed to的否定形式,如果是肯定的形式的话，过去式可以用managed to 代替，由于managed是manage的过去式，变成 I managed toget into town this morning.不过这里是否定形式，前面只有加助动词并加以否定才最佳，变成didn't manage to do ，这也同样是manage to的否定形式了。另外如果一定要用managed to来改写的写可以写成这样I hardly managed to get intotown this morning.(hardly:几乎不)
