  初中英语知识归纳

  一、引导词

  1.从句为陈述句,常选择引导词that,that引导宾语从句无意义,不充当句子成分常省略。例句:He told us (that)they would help us through the whole work.

  2.从句为一般疑问句,常选择引导词if或whether,表示“是否”。在 whether … or not 结构中不能用 if 替换。例句:I don't know if there will be a bus any more.

  3. 从句为特殊疑问句,常选择what,when,where,which,who,how等的疑问代词、副词作引导词。例句:He didn't tell me when we should meet again.

  二、判断时态情况:

  1.主句是一般现在时,从句可以为各种时态。

  2.主句是一般过去时,从句要用相应过去时态。

  注意:从句描绘客观事实、真理、自然现象等,从句时态不受主句时态限制,仍用一般现在时。

  例句:He answered that he was listening to me.

  Father told me that practice makes perfect .

  三、宾语从句的语序要用陈述句语序

  陈述句语序,就是主语在前,谓语动词在后。

  错误:He is wondering when can he finish this difficult job.

  正确:He is wondering when he can finish this difficult job.

  注意:宾语从句的否定转移

  主句的谓语动词是think,believe,imagine,suppose,consider,expect,fancy,guess等,并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致。例如:I don't think he will come to my party.而不能说成I think he won't come to my party.

  一般现在时的主要用法有两点:其一表示一经常发生的动作,如: I always go to scho

  ol at seven. 其二表示某一真理,事实,如: The earth moves around the sun.

  其一: Have been表示曾经去过,如:I have been to America twice. 说此话的人应已经回到国内。而He has gone to Japan.则此人目前已到日本去了。

  其二:截止性动词可以有现在完成时,但不可与表示一段长度的词连用,如: The clas

  s has begun. The class has been on for five minutes.

  ④ 一般将来时

  纯将来时的表示法: shall/will+动词原形
