Any student with any type of sense knows that when your in English class, the English you use for homework and the English you speak at home are WAY different. Apparently that student doesn't have a lot of sense.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
