Hello, do you want to improve your English or your English communication skills? The overall English level suggests that you buy online courses. If it's your communication skills, I'll tell you the truth, read it over and over again, and then tell foreign friends. If you lose it for a long time, it will definitely be scrapped. We usually ignore reading. Actually, reading is the best way to improve. We think a text can be done three times and five times. Actually, the standard is 2 10 times. Don't ask too many reasons at all, keep reading, and soon you will be fluent.
