I found a good web site.

I was thinkg that I needed to build up my vocabulary since nowadays I'm likely use very small range of words. So, I sometimes face the difficulty that I don't come up with proper words. One reason is that I'm in Korea so I don't speak in English in my daily life. Second, I don't read newspapers or watch TV as much as I did in the US. In addition, I'm preparing the entrance exam for medical school so I want to focus on that. It means I don't really work on English. I just don't want to forget how to speak or read. However, I really need to do something since I'm forgetting. So, I made up my mind that I will watch a video every morning and during my meal. I hope it would work out.

Hello [이름], I hope it works out for you. I'm glad you find time to improve on your English skill. I'm sure it'll pay off in the end. -RJ-  I was thinkg that I needed to build up my vocabulary since nowadays I'm likely use very small range of words.  >>I was thinking that I need to build up my vocabulary since nowadays I'm likely to use a very small range of words.  So, I sometimes face the difficulty that I don't come up with proper words.  >>So, I sometimes face the difficulty of not coming up with proper words.
