为什么用volunteering不用to volunteer有什么区别.

I am sure that the novel,once ( ),will prove a great success.
为什么要用published不能用to be published或者being published

只有spend some time doing sth的形式,没有spend some time to do sth的形式.
有逗号分开,不用being,整句相当于i am sure that once the novel is published,it will prove a great success.
1、doing表过去
2、后置定语-ed表现在,to be done表将来,being done表过去
1.to do有将来未发生的意思,这里用doing表示过去的事情
2.(it is)省略。完整的是once it is published.
