I also study Japanese. Learning English and Japanese together is really tiring. I remember I just studied Japanese for a semester. When I took CET-4, I always thought of Japanese words in my composition. Hehe ... in fact, learning Japanese is tiring enough, and learning English well can't be better ... in fact, it's mainly a matter of persistence and language learning. I must read and remember it every day. What about you? If you can persist, you have this.
