将英语从句转化为简单句的方法包括：去掉从句中的连词，例如"that"、"which"、"who"等；将从句中的主语和谓语提到句首；将从句中的动词改为-ing形式或不定式。
1. 去掉从句中的连词
有些从句中使用了“that”、“which”、“who”等连词，我们可以直接去掉这些连词，把从句变成简单句。例如：
从句：I think that he is a good person.
简单句：I think he is a good person.
2. 把从句中的主语和谓语提到句首
从句中的主语和谓语可以提到句首，变成简单句。例如：
从句：Although he is young, he is very talented.
简单句：He is very talented although he is young.
3. 把从句中的动词改成-ing形式或不定式
有些从句中的动词可以改成-ing形式或不定式，从而变成简单句。例如：
从句：I know that he is studying in China.
简单句：I know he is studying in China.
从句：I want to know if he will come to the party.
简单句：I want to know whether he will come to the party.
