What do you usually use the internet for?
This is a very good work, Serg. You addressed the question properly. Nicely done. Just be careful of using commas in your work as you forget to include one on your answer. Kindly take note of this correction:
Mostly, I use the internet to get information from websites and search engines, for file exchange and of course, for e-mail exchange.
Hope this helps. :)
I use internet mostly to get information from web-sites and search engines, for file exchange and, of course, for e-mail exchange.
No, you could use Mostly at the start of your sentence
