Sometime I'm getting negative results on my quizzes, tests but I'm study hard !
Also I want to read book like novel but I didn't have any excited.Why?
what is the main reason for this happen?
We can't tell you why you don't enjoy reading books, or why you don't find them exciting. Everyone has different tastes. Do you like to read novels in your own language? If not, you are unlikely to enjoy them in English. If you have a favourite book in your own language, try to find an English translation of it. You will already know the story, which helps because then you won't have to look up every word to try to work out the meaning.
