宾语从句的定义及用法

2016-08-30 来源: 作者: CSXDFMI


  2.连接词

  1)当由陈述句充当宾语从句时,用that引导,that无词义,在口语或非正式文体中常省略。如:

  He said that he could finish his work before supper.他说他会在晚饭前完成工作。

  2)当由一般疑问句充当宾语从句时,用if或whether引导,意为“是否”。如:

  I don't know if /whether he still lives here after so many years.

  但在下列情况下只能用whether:

  ① 在具有选择意义,又有or或or not时,尤其是直接与or not连用时,往往用whether(if…or not也可以使用)。如:

  Let me know whether /if he will come or not.(=Let me know whethe or not he will come)

  I don't know whether/if he does any washing or not.(=I don't know whether or not he does any washing.)

  I wonder whether we stay or whether we go.

  ② 在介词之后用whether。如:

  I'm interested in whether he likes English.我关心的是他是否喜欢英语。

  We're thinking about whether we can finish the work on time.

  I worry about whether I hurt her feelings.我担心是否伤了她的感情。

  ③ 在不定式前用whether。如:

  He hasn't decided whether to visit the old man.他尚未决定是否拜访那位老人。

  I don't know whether to go.我不知去否。

  He hasn't decided whether to go by bus or by train.他还未决定是乘公共汽车去还是坐火车去。

  ④ whether置于句首时,不能换用if。如:

  Whether this is true or not,I can't say.这是否真的我说不上来。

  ⑤引导主语从句和表语从句时宜用whether。如:

  Whether she will come or not is still a question.她是否能来还是个问题。

  The question is whether we can catch the bus.问题是我们能否赶上公共汽车。

  ⑥ 若用if会引起歧义时,则用whether。如:

  Please let me know if you like the book.可理解为:a. Please let me know whether you like the book.请告诉我你是否喜欢这本书。B. If you like the book, please let me know.你如果喜欢这本书,请告诉我。

  3)如果宾语从句原来是特殊疑问句,只需用原来的特殊疑问词引导。如:

  Could you tell me why you were late for the meeting this morning?
