Mastering language requires it to be heard and incorporated into one's auditory memory and spoken usage reflexes as well as being read from and written to the page. To this end, we are including audio files to accompany the written pages on this site.
There is a vast difference between reading challenging material and hearing it spoken in living context by someone who understands it. In the latter case, the rhythm and melody of the language are allowed to add further dimensions to the otherwise static and flavorless words. We strongly recommend listening repeatedly to vocabulary exercises and other grammar resources when audio versions are available, as this is demonstrably the most effective way to assimilate expression and vocabulary into one's own active language usage.
