楼上说的对,但跟问题中的例句似乎关系不大.
ought to do中,to do并不是不定式,ought to 应看作一个整体,相当于一个情态动词,所以这个句子变不定式应按情态动词的变法:
can do --> can be done
ought to do --> ought to be done
People oughtn't to criticze her for this matter.
-->
She oughtn't to be criticized (by people) for this matter.
记住to be done的真理
let/hear/see/make/watch这些词是不带to的动词不定式.let/hear/see/make/watch+sb+do/dong他们的不定式应该为:be+不带to的动词的过去分词+to+do或者是be+不带to的动词的过去分词+doing.例如:Ilet him write. He is let to write.
