从句

• 名词从句

    • whether
    • where
    • when
    • how
    • who
    • that
  • 宾语从句
    • 确定的信息做宾语从句：I saw that the rabbit ate a carrot.
    • 不确定的信息做宾语从句：I saw who ate the carrot.
      • 1.除了某些介词参与的情况，从句的引导词基本都在从句的开头
      • 2.不要再看到whether/where/when/who就以为看到了包含疑问代词/疑问副词的问句，错误的加上助动词
    • 有时可省略that
    • 某些词后的宾语从句的否定 eg：I think (that）the rabbit is smart.→I don′t think (that）the rabbit is smart. 否定往往加在谓语动词前，而非从句中
    • 主句时态等于宾语从句时态 eg：I don′t think that you are right. 如果从句表示客观事实，则用一般现在时 eg：I knew that the sun rises in the east.

    • be➕adj➕that：形容词通常都是表达某种看法/判断，That引导的从句相当于看法/判断
