宾语从句引导词是什么意思宾语从句引导词是什么宾语从句引导词that可以省略

宾语从句的引导词根据从句类型和语境不同,主要分为下面内容三类:

一、从属连词

  • that

    • 用于引导陈述句转化的宾语从句,无实际含义,口语中常省略。
    • 例句:

      I know (that) he is honest.
      He said (that) he would finish the work.

  • if/whether

    • 引导一般疑问句转化的宾语从句,表示“是否”。
    • 区别:
      • 只有whether能接”or not”(如whether…or not)
      • 介词后只能用whether(如about whether)
      • 不定式前只能用whether(如whether to go)
    • 例句:

      I wonder if/whether he will come.
      They discussed whether they should cancel the trip.


二、连接代词

用于引导独特疑问句转化的宾语从句,包含疑问含义的代词:

  • who/whom/whose(谁/谁的)
  • what(什么)
  • which(哪一个)
  • whatever/whoever/whichever(无论什么/谁/哪个)

例句:

Do you knowwho broke the window?
Tell mewhat you need.
I’ll acceptwhatever you decide.


三、连接副词

用于引导独特疑问句转化的宾语从句,表示时刻、地点、缘故、方式等:

  • when(什么时候)
  • where(何地)
  • why(为何)
  • how(怎样)
  • whenever/wherever/however(无论什么时候/何地/怎样)

例句:

He askedwhen the train would arrive.
Can you explainwhy you were late?
I don’t knowhow he solved the problem.


独特注意事项

  • 语序:无论引导词是什么,宾语从句必须用陈述语序(主语+谓语)。

    • 错误:She asked where was the library.
    • 正确:She asked where the library was.
  • 时态一致性:主句为过去时,从句需用对应过去时态(客观真理除外)。

    • 例句:

      He said (that) the Earthrevolves around the Sun. (客观事实用一般现在时)
      She told me shehad finished her homework.

  • 形式宾语it:当宾语从句后接补语时,需用it作形式宾语,从句后置。

    • 例句:

      I findit strangethat he didn’t call.

  • 否定前移:在think/believe等动词后,否定词常转移至主句。

    • 例句:

      Idon’t think (that) he is right.


从句类型 引导词 示例
陈述句 that(可省略) He said (that) it was true.
一般疑问句(是否) if/whether I wonder if she agrees.
独特疑问句(疑问词) what/when/where/why/how等 Tell me where you live.

通过合理选择引导词并注意语序、时态等制度,可准确构建宾语从句。
