Not only did patients who had two days’ bed rest do totally as well as those given seven days, they spend only half as much time altogether standardized work.

1、Not only did patients do totall……，这里的“do”怎么理解？

2、as much time altogether standardized work.这里是不是少了一个“as”，应该为as much time as altogether standardized work.?

回答：1、do在这里为不及物动词，是表现的意思。

   2、they spent only half as much time altogether （on）standardized work as those given seven days did

整句大致意思：卧床休息2天的病人其表现与那些卧床休息7天的病人同样好，前者进行标准化工作的时间仅为后者的一半。
