当从句主句所表示的行为所发生的时间不一致时，动词的形式要根据它所表示的时间作出相应的调整。

虚拟条件句中的省略和倒装，将______/________/_________置于句首，将________省略。

1). If I had not seen him then, I wouldn't have been very happy. 2). If I were you, I would accept his advice. 3). If it rained/should rain/were to rain tomorrow, I would stay at home.

3. 含蓄条件虚拟句。有时为了表达的需要，在虚拟语气中，并不总是出现if引导的条件句，而

通过其它手段来代替条件句。常用的有介词with，without，but for（倘没有，要不是）；连词

or，but；副词otherwise等。
