中考复习知识点之宾语引导词的判断

2021-04-30 09:16:14中考网编辑

  中考网整理了关于中考复习知识点之宾语引导词的判断,希望对同学们有所帮助,仅供参考。



  1. that,后跟陈述句,无意义,口语中可省略。

  【例】They know(that)she is an English teacher.

  分析:从句she is an English teacher是一个完整的陈述句,不缺少任何成分(如主语、宾语等),引导词用that。

  2. if和 whether表“是否”,多数情况下二者可互换。

  【例】I wonder if/ whether you have already finished your homework.

  ※ 易错点:只用whether不用if的情况

  ① 当与or not连用时

  【例】I wonder if/ whether you have already finished your homework.

  = I wonder whether you have already finished your homework or not.

  = I wonder whether or not you have already finished your homework.

  总结:无论or not位置在前面还是后面,出现or not就只用whether。

  ② 宾从作介词的宾语时

  【例】He was worried about whether he would lose his job.

  介词about后面,宾从的连接词只能用whether。

  ③ Whether引导的宾从放在句首时

  【例】Whether we can arrive there on time, I am not sure.

  3. 特殊疑问词。当宾语从句是特殊疑问句时,由疑问代词(what、who、which、whose、whom等)和疑问副词(where、when、why、how)引导。

  ※ 总结:问什么就用什么

  【例】I didn’t know who was late for school this morning.  (问人——who)

  【例】I don’t remember when we arrived here.  (问时间——when)
