When you learn a new language, you need to spend a lot of time reading. The new language will certainly be different from your own language. Some people spend a lot of time learning the new language and they succeed. Others spend hardly any time and they don't learn much at all. They don't take their study seriously.
I found a book that you can use online, thanks to Google Books. It has a lot of vocabulary and this will help you learn the language.
Here is the link for you to see. Just remember that this book costs 50 dollars at the shops if you want to buy it. You can read it for free online if you want. I really recommend it for you. Please tell me in class if you find it useful or not.
