The Subjunctive MoodRevisionLearning aims
1. To review unreal conditionals with “if clause”, inverted structures and mixed time;
2. To grasp usage of noun-clause and some special structures in subjunctive mood. If sb….,( 条件句)sb. …. ( 主句)Present
(现在)Past
(过去)Future
(将来)did/wereA.had donewould/could/should/
might doD.would/could/should/might have doneB. did/were
should do
were to doOpposite to…虚拟语气C.would/could/should/
might do倒装的If虚拟句
如果条件状语中有were, had, should时, 可以将if省略,同时were ,had ,should提至句首,构成倒装,表示虚拟条件
即:Were / Should / Had +主+其他
虚拟语气时态的判定
当假设条件句的主句和从句表达的时间
不一致时,我们应使用混合时间的假设条件句,动词的形式要分别根据它所表示的不同时间做相应的调整,变法同if条件虚拟句的主从句谓语动词变法。Practice 1. If I hadn’t stood under the ladder to catch you when you fell, you now.

含蓄虚拟条件句在虚拟语气中,有的句子可能没有明显的由“if”引导的条件从句,但是,仔细一分析就会发现句子中隐含着一个条件,这种句子称为含蓄条件句
含蓄的条件可以用下列方式来表达:
(1)介词或介词短语
常见的有:but for(要不是), with, without, in that position(在那个位置), in the absence of(没有), under, in, for the fear of,in that case(如果是那样的话)…含蓄虚拟条件句(2) 连接词常见的可以用来引导虚拟语气的连接词有:and, but, but that, or, or else, other, otherwise(否则)等。
