Nominalization

In the last GWC class, we learnt deference between speak language and written language, and nominalization.
Nominalization means transforming the structure of a sentence by using a preposition.
For example; the trial was successful →　success of the trial

By using this technique, one can reduce clauses in one sentence and make the text more suitable for academic writing.
I think this nominalization is very important in written language and can be adopted right away, so I want to make use of it when I write an essay.
