News vocabulary is hard to learn

Our teacher let us to studying new words. We have to read twenty new words in one day. Every weekend, when we go to LHU, we have to join a quiz on Sunday.  In my person, I think this is a trick. I think teacher lied to us. He told us if we studying hard, so we can have good English skill in the future.  Seriously, I want to be a good student and studying hard. But I just a human been. And I need to working hard everyday. I cannot spend all day to readying book. Why I think this is a big trick? Because when I was child, my teacher of elementary school and teacher of mid- school both told which I could be a musician  in my future. They just say something and we should spend all day long doing something .  He has never understood us since last year.
