答案：
25. D
译文：我们后天走，要是他们在这之前到达，我们就可以痛痛快快地撮一顿。
本句涉及省略if 的虚拟条件句。
26. B
译文：她要是现在就走的话，星期天就到那儿了。
本句涉及if引导的虚拟条件句，表示与将来事实相反的假设。表示与将来事实相反的非真实条件句，从句中的谓语动词用"were to +动词原形或should +动词原形"，主句中的谓语动词用“should （第一人称）, would （第二、三人称）+动词原形”。如从句中省去if ，主谓要用倒装结构。
27. C
译文：我当时要是没生病的话，就帮他了。
本句涉及省略if的虚拟条件句。虚拟语气也常用于“If it were (had been) not for … ”句型中，意为“要不是… … ”。If it were not for… 表示与现在事实相反的假设。从本句的主句来判断，这是一句与过去事实相反的虚拟条件句，If it had not been for … 表示与过去事实相反的假设，与主句中的谓语动词相一致。在正式文体中，有时可把虚拟条件句中的连词if 省去，而将were, had, should 等助动词（不包括行为动词）提到主语前面，用倒装结构。如果句中没有were, had 或should 时，既不能省略if,也不能倒装。
