状语从句省略成分后的常见类型：连词+ 现在分词 / 过去分词 / 介词短语/ 形容词。If invlved in this case，yu will be punished. 如果卷入这件事，你将受到惩罚。（省略yu are）If necessary，yu can chse me t make the presentatin. 如果有必 要的话，你可以选择我来做这个报告。（省略it is）以下为约定俗成的省略形式： if s 如果是这样的话 if nt 如果不是这样；否则if ever 如果曾经有的话 if any 如果有的话if/when necessary 如果有必要的话/ 在必要的时候if/when pssible 如果可能的话/ 在可能的时候
