简化宾语从句常见用法

　　方法一：当主句谓语动词是hope¹， decide²， wish， choose， agree³， 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 hopes⁴ he will be back very soon. →Li Ming hopes to be back very soon.

　　We decided⁵ that we would⁶ 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：

　　Could⁷ 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 headmaster⁸ ordered⁹ 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，可以用介词加动名词（短语）等其他形式简化。例如：

　　He insisted¹⁰ that he should go with us. →He insisted on going¹¹ with us.

　　The poor boy doesn't know when and where he was¹² born¹³. →The poor boy doesn't know the time and the place of his birth¹⁴.

　　方法五：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 found¹⁵ that there was a wallet¹⁶ lying¹⁷ on the ground¹⁸. → Liu Ping found a wallet lying on the ground.

　　方法六：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 seemed¹⁹ 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 covered²⁰ 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.
