含蓄条件句

非真实条件句中的条件从句有时不表示出来，只暗含在上下文中，这种句子叫做含蓄条件句。含蓄条件句大体有三种情况:

1.条件暗含在短语中。如：without,butfor,incaseof.etc

Ihavebeensosuccessfulwithoutyourhelp.

Butforyourhelpwecouldn’thavesucceededintheexperiment.

2.条件暗含在上下文中.如：or,otherwise

Iwasverybusyyesterday.OtherwiseIwouldhavecometoseeyou.

3.条件用其他形式来表示Ifonly,suppose/supposing/providing….Suppose
