高三复习名词性从句和非谓语转换
名词性从句与非谓语一、名词性从句与动名词名词类的从句可以被化简成动名词和不定式。
1.2.1.that引导的主语从句与动名词例: 1(1) It surprised us that John won the marathon.John`s winning the marathon surprised us.例: 2(1)That he lost the game came as a surprised to everybody.That he knows English helps him start a conversation with foreigners例：3(1)That he was out of work was unexpected(2)That she was ill made her mother worried.(3)That he was chosen as our chairman made us excited.2.that引导的同位语从句与动名词由原来的同位语从句结构“名词+that同位语从句”变成了一个动名词结构“名词+of+动名词的复合结构”。
例: 1(1)There was no chance that Davy would come from the battle alive.(2)There was no chance of Davy coming from the battle alive.例:2(1)We were greatly encouraged by the news that china had launched another man-made satellite.(2)It is said that the book has been translated into many other languages.The book is said to have been translated into many other languages(3)It was reported that the bank in the local has been robbed in broad daylight yesterday(4)it is thought that he is the greatest person in the world.(5)It is arranged that the class meeting will be held next week.3.that引导的宾语从句与动名词由that引导的宾语从句的简化较为复杂，因为它可以转换成动名词，也可以转换成不定式，这主要与主句谓语动词的用法密切相关。
从句与非谓语动词之间的转换
非谓语动词与从句的相互转换一、如何把复合句改为简单句呢首先，分清主从复合句，先要取消从句，一般要把引导从句的连词去掉。
例如：When he was waiting for the bus, he saw a dog.→Waiting for the bus, he saw a dog.其次，如果从句的谓语动词是主动式，就要把谓语动词改为现在分词;如果从句的谓语动词是被动式就要把谓语动词改为过去分词;并且要注意时态的变化。
例如：1. After he had finished his homework , he went home.→Having finished his homework, he went home.2. Because I have promised to meet my friend at the airport, I can’t accept your invitation.→Having promised to meet my friend at the airport, I can’t accept your invitation.【3. As he was deeply moved by the story, he couldn’t keep back his tears.→Deeply moved by the story, he couldn’t keep back his tears.4. As he was born into a tenant farmer family, he had only two years of schooling.→Born into a tenant farmer family, he had only two years of schooling.另外，还要注意在用分词短语作状语时，它逻辑上的主语必须与句子的主语一致。
如果主从句的主语不一致，在取消掉从句变为 -ing 或 -ed形式时，要把从句的主语保留，其它部分和以前的改法一样。
