xuni1（xuni1） The three basic types of subjunctive conditionals: Contrary to present facts, contrary to the facts of the past and contrary to the facts of the future. There are two kinds of conditional sentences: the real conditional sentence and the unreal (virtual) conditional. The hypothesis expressed by a real conditional sentence is possible, rather than a real conditional sentence, which usually represents an imaginary, contrary to, or unlikely to happen: If, I, have, time, I, will, go, with, them.. If I had time, I would go with them. (indicative mood) If, I, were, you, I, would, go, with, them., if I were you, I would go with them. (subjunctive mood) And now contrary to fact If right now, the conditional predicate in the past tense (usually were be), the main predicate should (would, could, might) + verb: If, I, knew, her, number, I, could, ring, her, up., if I know her phone number, I can call her. (unfortunately, I dont know.) Contrary to the past facts If contrary to the past facts, the conditional predicate in the past time (had+ past participle), subject predicate should (would, could, might) +have+ past participle: If, I, D, left, sooner, I, D, have, been, on, time., if I had left earlier, I would have arrived on time. (but I left too late) Contrary to fact and future If the future and instead, the conditional predicate in the past tense (usually were be), the main predicate should (would, could, might) + verb: If I, asked, him, m, I, sure, he, us., D, help, if I ask him, I am sure he will help us. (but Im not going to do that.) Note: what are the special instructions? The workers in should is mainly used in the first person after. The general difference between would, might, and could is that would represents the outcome, might represents the possibility, and could indicates ability, permission, or possibility. Compare: If, you, tried, again, you, would, succeed., if you try again, youll succeed. (table would results) If, you, tried, again, you, might,
