规律总结： 连词that在引导名词性从句时本身没有意义，在从句中不担任任何句子成分，但引导主语从句、表语从句、同位语从句时不能省略。在宾语从句中有时可省略。
(1)that引导主语从句位于句首时，that无意义，但是不可省略。
(2)that从句作主语时，常用it作形式主语，常见的句型有：
①It＋be＋形容词(bvius, true, natural, surprising, gd, wnderful, funny, pssible, likely, certain, prbable, etc.)＋that从句。
②It＋be＋名词词组(n wnder, an hnr, a gd thing, a pity, n surprise, etc.)＋that从句。
③It＋be＋过去分词(said, reprted, thught, expected, decided, annunced, arranged, etc.)＋that从句。

(同位语从句)我给自己做出承诺：今年，我上高中的第一年，将会与以往不同。
(1)that引导表语从句时，一般不省略。
(2)that引导同位语从句时，应在某些抽象名词如fact, hpe, desire, thught, suggestin, idea, news, prblem, pssibility等后，对前面的名词起补充说明的作用，that只起引导同位语从句的作用，在从句中不充当任何成分，一般不省略。
