时间:2012-12-29 17:27 来源:建通教育中考资讯网 编辑:井林英 点击:

①The children didn't know who he was.孩子们不知道他是谁。
②He asked his father how it happened.他问他父亲这件事是如何发生的。
3)如果宾语从句所表示的是客观事实、普遍真理、自然现象或习惯性动作等,不管主句用什么时态,从句时态?#21152;?#19968;般现在时。如:
The teacher said that the earth goes round the sun.老师说地球绕着太阳转。
4.注意:
if和when既可以引导宾语从句,?#37096;?#20197;引导状语从句,应注意它们在两种从句中的意思和用法的不同。if和when引导宾语从句时,分别意为“是否”和“?#38382;?rdquo;,其时态应和主句时态相呼应;它们引导状语从句时,意思分别为“如果,假如”和“当……时候”,当主句时态是一般将来时时,其时态用一般现在时。它们常常放在含有状语从句和宾语从句的题干中进行综合考查。如:
—Do you know when he will come back tomorrow ?你知道他明天什么时候回来吗?
—Sorry,I don't know.When he comes back,I'll tell you.对不起,不知道。当他回来了,我将告诉你。
—I don't know if he will come.我不知道他是否会?#30784;?br /> —He will come if it doesn't rain.如果不下雨,他会来的。
简化宾语从句常用六法
同学们常会遇到把含有宾语从句的复合句转化为简单句,使其与原句意思相同(或相近)的试题。下面就介绍几种常用的简化宾语从句的方法:

  方法一:当主句谓语动词是hope, decide, wish, choose, agree, promise等,且宾语从句的主语与主句主语一致时,宾语从句可简化为不定式结构。例如:
  Li Ming hopes he will be back very soon. →Li Ming hopes to be back very soon.
We decided that we would help him. →We decided to help him.

  方法二:当主句谓语动词是know, learn, remember, forget, tell等动词,且主句主语与从句主语一致时,宾语从句可简化为“疑问词+不定式”结构。例如:
  She has forgotten how she can open the window. →She has forgotten how to open the window.
  注:当主句谓语动词是tell, ask, show, teach等动词,且后带双宾语,从句主语?#22270;?#25509;宾语一致时,宾语从句可简化为“疑问词+不定式”结构。例如:
Could you tell me how I can get to the station? →Could you tell me how to get to the station?

  方法三:当主句的谓语动词是order(命令),require(需要)等时,如果主句和从句的主语不一致,宾语从句可简化为“名词(代词)+不定式”结构。例如:
The headmaster ordered that we should start at once. → The headmaster ordered us to start at once.

  方法四:某些动词后的宾语从句,可以用介?#22987;?#21160;名词(短语)等其他?#38382;?#31616;化。例如:
  He insisted that he should go with us. →He insisted on going with us.
The poor boy doesn’t know when and where he was born. →The poor boy doesn’t know the time and the place of his birth.

  方法五:某些动词后面的宾语从句可转化为“宾语+V-ing?#38382;劍?#20316;宾语补足语)”结构。例如:
  Liu Ping found that there was a wallet lying on the ground. → Liu Ping found a wallet lying on the ground.
  方法六:动词seem后的宾语从句,?#37096;?#20197;用不定式(短语)来简化,但句型需要进行?#23454;?#30340;变化。例如:
It seemed that the boys were going to win. →The boys seemed to win.

除上述方法外,还有一些特殊句式的转化。

例如:
  I found that it was difficult to learn English well. →I found it difficult to learn English well.
Soon we found that the ground was covered with thick snow. →Soon we found the ground covered with thick snow.
They found that the box was very heavy. →They found the box very heavy.
