1. A computer-implemented method for automated teaching of languages, comprising; receiving, by a hardware processor, a text content in a natural language; parsing the received text content into one or more sentences; determining a syntactic model of the each sentence; determining a frequency of occurrence for each syntactic model based on a number of sentences associated with each syntactic model in the text content; sorting the one or more syntactic models based on each respective frequency; and generating one or more language teaching exercises, wherein an exercise includes one or more sentences selected based on the frequency of associated syntactic model.
