3．含蓄条件句 有时为了表达的需要，在虚拟语气中，不出现条件句，而是 以介词短语、并列句、副词、非谓语动词的形式出现。这种 句子我们称其为“含蓄条件句”。 常见的介词短语有 without...“没有……”； but for...“要不 是……”；连词有but “但是”；副词otherwise “否则的话 ……” 等或根据上下文来表示某种假设的情况。 The ship would have sunk with all on board but for the efforts of the captain. 要不是因为船长的努力，我们就会连船带人都沉没了。 He would have given you more help，but he was so busy at that time. 他本可以给你更多的帮助，但那时他太忙了。
