英语名词从句简单句知识总结思维导图

• 简单句与名词从句
  • 何谓名词从句
    • 在英文中，名词或名词短语主要充当四种句子成分：主语、宾语、表语和同位语。 如果把句子当做名词来用，分别充当另一句话的主语、宾语、表语和同位语，于是 便构成了四种从句：主语从句、宾语从句、表语从句和同位语从句。因为这四种从句 在本质上相当于名词的作用，所以统称为名词从句。
      • 主语
        • The book is interesting.
          • 名词短语the book做主语
            • 简单句
        • What I am reading is interesting
          • 完整的句子what I am reading作主语 因此称为主语从句。
            • 主语从句
      • 宾语
        • No one knows exactly the life on other plants.
          • 名词短语the life on other plants作宾语
            • 简单句
        • No one knows exactly whether there is life on other plants.
