我们每个人都能制造奇迹，关键是我们想要的究竟是什么，以及为了这个想要的，情愿付出多大的代价。假如为了你想要的那个东西你情愿付出一切的代价，那么你将制造下一个奇迹。学****也是一样需要付出的!以下是我给大家可以转化为if引导的条件句。常用来表示含蓄虚拟条件的手段有：
(1)介词或介词（短语）。如but for，but that，without,in case of, under more favorable condition等。
(2)连词。如so that, unless, in case, supposing,lest, provided(如果……)，for fear that(生怕)，in orderthat, on condition that, if only(要是……就好了)等。
留意：lest, for fear that和in case引起的从句中谓语动词多用should+动词原形，但也可以不用虚拟语气，而用动词的陈述语气形式。例如：The foreign teacher spokeslowly in case we misunderstood him这位外籍老师说得很慢以免我们误会。
(3)通过上下文及内在含义，句中往往有but,otherwise, unfortunately等类似转折词。
without, but. but for, otherwise引起的短语或（句子）常暗含着含蓄条件。例如：
4
①Without you,1 would never know him
②But for your oooperation, we wouldnt have done it
③But that she was afraid, she would have said no. .
④i would be most glad to help you, butI am busy now.
⑤I would have come to the party yesterday, but ljwas working.
⑥I am busy now, otherwise l would do you the favor!
