There is a lot of hype surrounding the new rapper.

there be存在句中，there为形式主语，be为不及物动词作谓语，be后的名词为真正主语。作主语的名词可以后接不定式、现在分词或定语从句作后置定语。动名词不能做后置定语，因此主语后的doing都是现在分词作定语。

There 形式主语 is 谓语 a lot of限定词 hype 主语 surrounding the new rapper现在分词短语作定语。

网友自己写的句子有语法错误。There is a lot of money nobody using. 该句中 a lot of money为主语，nobody using则为结构错误，因为这个结构不能做定语。要么改为不定式作定语，要么改为定语从句。例如，There is a lot of money yet to be used. There is a lot of money that can be used. There is a lot of money for us to use.
