英语虚拟语气
虚拟语气中有种被称为是含蓄条件虚拟语气的,理解不是很透彻,最好各种用法都涉及到,配上例句,不要粘啊

Answer 1

非真实条件从句
由if,as if,as though引导的条件从句叫做一般条件句
所谓含蓄虚拟语气,就是句子里不出现明显的假设条件从句,但假想的条件隐含在上下文逻辑关系中,或通过一些语法手段得以体现,这种情况就称为含蓄虚拟语气.
--含蓄条件暗含在其他结构中.
(1)连词but（但是）,or (else) (否则）；副词otherwise（否则）,unfortunately等表示转折假设.
如：
A safety analysis would have identified the target as a potential danger.Unfortunately,it was never done.
Victor obviously does not know what has happened; otherwise he wouldn't have made such a stupid remark.
(2)介词短语暗含假设条件,常用的有：without（若没有）,but for / but that（要不是因为）,except for（若没有）,with（若带有）,under more favorable conditions,in the absence of（在没有……的情况下）,under the circumstances of（在……的情况下）等.
如：
But for the English examination I would have gone to the concert last Sunday.
(3)intended/meant/hoped/wished/plann或was/were +不定式完成式或had intended/meant/planned/hoped/wished +不定式一般式暗示虚拟语气.
如：I intended to have called on you,but I was busy at that time.（事实上我没打电话）
(4)情态动词完成式暗示虚拟语气.
如：I should have called to make an airline reservation.(事实上我没有）
