一、宾语从句的简化：宾语从句的简化是指英语中含宾语从句的复合句可转化为简单句, 意思不变。
二、宾语从句简化的方法：
1.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：①Li Ming hopes he will be back very soon. 李明希望他很快回来。→Li Ming hopes to be back very soon.
②We decided that we would help him. →We decided to help him.我们决定帮助他。
2.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. 她忘记了如何打开窗户。→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，从句主语和间接宾语一致时，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?你能告诉我怎么去车站吗？ →Could you tell me how to get to the station?
3.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. 校长命令我们立即开始。→ The headmaster ordered us to start at once.
4.某些动词后的宾语从句，可以用介词加动名词(短语)等其他形式简化。
例如：①He insisted that he should go with us. 他坚持要和我们一起去。→He insisted on going with us.
②The poor boy doesn't know when and where he was born.这个可怜的孩子不知道他何时何地出生的。 →The poor boy doesn't know the time and the place of his birth.
5.某些动词后面的宾语从句可转化为“宾语+V-ing形式(作宾语补足语)”结构。
例如：Liu Ping found that there was a wallet lying on the ground. 刘平发现地上躺着一个钱包。→ Liu Ping found a wallet lying on the ground.
6.动词seem后的宾语从句，也可以用不定式(短语)来简化，但句型需要进行适当的变化。
例如：It seemed that the boys were going to win. 看来男孩们会赢。→The boys seemed to win.
7.除上述方法外，还有一些特殊句式的转化。例如：
①I found that it was difficult to learn English well. 我发现学好英语很难。→I found it difficult to learn English well.
②Soon we found that the ground was covered with thick snow. 不久，我们发现地上覆盖着厚厚的雪。→Soon we found the ground covered with thick snow.
③They found that the box was very heavy. 他们发现这个箱子很重。→They found the box very heavy.
