  三移:就是把主语和谓语移到后面。

  注意:在感叹句中,不得出现so,very,very much等表示程度的单词。

  一判:beautiful为形容词;二定:beautiful为形容词,用How 来引导;三移:把Our school is移到How beautiful后面,即为感叹句How beautiful our school is!

  ②He is a clever boy.

  一判:boy为名词;二定:boy为名词,用What来引导;三移:把He is移到What a clever boy 后面,即为感叹句What a clever boy he is!

  一判:well为副词;二定:well为副词,用How 来引导;三移:把He studies移到How well后面,即为感叹句How well he studies!
