If we use a kind of active inference ,like suggest, assume in the objective clause, we use the phase"should have+ past participle" to follow it, and the word "should" can be omitted. If we want to express the active inference or advice in the past tense, we use"suggested and assumed", then we follow it by"had+ past participle". we should change the tense depending on the tense of main sentence.
ReplyDeleteWhat's an objective clause? I don't know what you mean by "active inference."
