方法一：當(dāng)主句謂語動詞是hope， decide， wish， choose， agree， promise等，且賓語從句的主語與主句主語一致時，賓語從句可簡化為不定式結(jié)構(gòu)。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：當(dāng)主句謂語動詞是know， learn， remember， forget， tell等動詞，且主句主語與從句主語一致時，賓語從句可簡化為“疑問詞+不定式”結(jié)構(gòu)。例如：
She has forgotten how she can open the window. →She has forgotten how to open the window.
注：當(dāng)主句謂語動詞是tell， ask， show， teach等動詞，且后帶雙賓語，從句主語和間接賓語一致時，賓語從句可簡化為“疑問詞+不定式”結(jié)構(gòu)。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：當(dāng)主句的謂語動詞是order（命令），require（需要）等時，如果主句和從句的主語不一致，賓語從句可簡化為“名詞（代詞）+不定式”結(jié)構(gòu)。例如：
The headmaster ordered that we should start at once. → The headmaster ordered us to start at once.
方法四：某些動詞后的賓語從句，可以用介詞加動名詞（短語）等其他形式簡化。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：某些動詞后面的賓語從句可轉(zhuǎn)化為“賓語+V-ing形式（作賓語補足語）”結(jié)構(gòu)。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：動詞seem后的賓語從句，也可以用不定式（短語）來簡化，但句型需要進行適當(dāng)?shù)淖兓�。例如�?br> It seemed that the boys were going to win. →The boys seemed to win.
除上述方法外，還有一些特殊句式的轉(zhuǎn)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.
