As long as you know the phonetic symbols, you can pronounce them. It doesn't matter if phonetics doesn't. I recommend the first volume of Xu Guozhang English, which has a detailed explanation of phonetic symbols. After learning phonetic symbols, buy a concise grammar and learn it from beginning to end. English grammar is relatively simple, you have experience in learning small languages, and it is easier if it is Spanish. At the same time, read aloud and recite 200 CET-4 words every day. It doesn't matter if you can't remember them, but they look familiar. After a month's hard work, your English will have a certain foundation. Start practicing listening and buying questions every day. If you think it's almost enough, do the real questions, touch the bottom, see what weaknesses there are, and focus on review. Generally, the first month is to remember words and learn basic grammar. When you start doing problems in the second month, you should learn to constantly summarize and improve. If you stick to it, you'll be fine after six months. Believe in yourself, persistence is very important!
