Not a cheat crib, if I found your teacher of English will do, and so do your fellow learners.https://en.wikipedia.org/wiki/Beowulf:_ ... Commentary
It´s just a kick-off, then you can get some key words and run a more thorough search. Try to see something about the film, books, etc.
PS. I don´t condone academical cheating, when my children have to study a subject and go to Google, then after that they have to say me out loud exactly what is in their mind.
And I am very concious of the word choice, if they can describe what they studied (if in other words), they have learned something!
PPSS. After having read, say, the Wikipedia, put the feature aside and try to talk about the topic to a friend, a teacher, somebody else. If he understand exactly what you meant, you have learned the ropes!
Then you search more, and then sums up again, the more you do the more you get the hang of it.
