Whenever (it is) possible, they would stop him and ask him the three questions. Will you be free this Sunday? If (it is) so, let's go camping. [名师点津]　省略句中的谓语动词和主语之间构成主动关系，则使用现在分词；若构成被动关系，则使用过去分词；若谓语动词表示的动作尚未发生，则使用不定式。 When (it is) heated, ice can be turned into water. 2．定语从句的省略 (1)在限制性定语从句中，作宾语用的关系代词whom, which, that可省略(但whom，which紧跟在介词后时不能省略)。 The exact year(which/that) Angela and her family spent together in China was 2008. (2)修饰way的关系词that/in which可以省略。 The way (that/in which)he speaks to us is really annoying. 3．宾语从句的省略 及物动词后接宾语从句时，连接词that一般可以省略；但如果及物动词接两个或两个以上that引导的宾语从句，那么只有第一个that可以省略。 I truly believe (that) beauty comes from within. He said (that) the text was very important and that we should learn
