请划分下面一个句子的结构
It was an atom that contained in the form of pure energy the fundermanental components of the entire universe.
答
It was an atom that contained in the form of pure energy the fundermanental components of the entire universe.是个强调结构.
（It was ）an atom （that） contained [in the form of pure energy] the fundermanental components of the entire universe.
()中的是强调结构的句式,[]里面的是状语.剩下的是句子主干.
