听说英语中写作用高级的句子比用一般句子拿的分高很多。求怎样把一般的几个简单句改为从句或复合句。

最好尽量详细一点，有例句，方法要具体

I have the money. I will go abroad. 简单句
I have the money and I will go abroad. 并列句
If I have the money, I will go abroad. （条件）状语从句（有好多种，条件，地点，原因，结果，关键是相关引导词的积累，比如表原因的从句引导词有很多，除了because, 还有due to/for/since/ as a result of/ on acount of/nowthat/owing to）
Having the money, I will go abroad. 非谓语动词（主从一致 主动）
I, who have the money, will go abroad. 定语从句

I am given the money. I will go abroad.简单句
Given the money, I will go abroad. 非谓语动词 （主从一致 被动）
