I know learning English is really hard compared to learning other languages. What I recommend you to do is enroll in a ESL class that is available in your local community college. They are really cheap.. My mom signed up for a ESL class, and she had to pay only like 200 dollars or something.
If you are in high school, they offer a ESL class for free.. So you should really take advantage of that program if you are a high school student.. As far as I know about ESL program online, there are some good tutorials that you can buy from online. Some good places are such as amazon.com or rosettastone.com. Although rosettastone is kind of pricey, they are really worth your money.
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.
