求助一道非谓语动词的选择题
The research is so designed that once _____ nothing can be done to change it .
A.begins B .having begun C.beginning D.begun
我认为应该选C,因为从“研究开始”这种说法来看research和begin应该是主动关系阿,而且在一个辞典上还有一个例句是“The work on the railway project will begin in 2008.”我觉得这里的work同本题的research一样,对于begin用主动形式

应该是D
The research is so designed that once (it is) begun,nothing can be done to change it.
这里的begun是被动语态做形容词
once (it has) begun,这么理解可不可以呢?
但是一般还是begin the research吧,所以ls的被动的更好些吧
