body: Let's say I copy a scene of 10 to 30 sentences from a book of another language to use as an example to teach vocabulary and explain sentence structure to my website. Can this fall under fair use? I could even copy passages from books or samples which are already made publicly available by the publisher online and I would credit the source as well.
  
  
  Edit: I'm in Canada
  
  
  Edit 2: I forgot to ask if it makes a difference whether the content of my website is publicly accessible for free compared to offering it as a course for paid members (with a free trial/sample available). 
  
  
  Thank you for the help.
