That depends on what you mean by "simplified English". Unlike Chinese there is no difference between spoken and written English. However, things can be phrased in many different education levels. Your sentence is scored (by Flesch-Kincade) at a grade 16 level (I believe that is a college graduate) which is 8 levels above the average for a US citizen's.
