簡化賓語從句常見用法

　　方法一：當主句謂語動詞是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構。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”結構。例如：

　　She has forgotten how she can open the window. →She has forgotten how to open the window.

　　注：當主句謂語動詞是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”結構。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”結構。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)”結構。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?shù)淖兓?。例如?/p>

　　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.
