English, junior high school grammar is not much. It is not easy to learn English only from grammar. First of all, you need to be familiar with the text, learn grammar from the text and see how others use it. I'm sure you can follow the gourd painting gourd ladle. Secondly, the usual exercises should be done carefully, which will contain a lot of learning content in your class. Doing exercises is to consolidate. Furthermore, words should be memorized. Some people say that rote learning is no good, but you have to memorize it. Generally, you have a good memory before going to bed, so you can use it. Write your words on the small card and take them out when you have time. Also, don't neglect spoken English, you can listen to English songs or try to watch English movies and magazines. Speak more and speak bravely.
The important thing is to persist, don't worry, and believe that you can persist. It's not that you can't learn, but your subconscious inertia is holding you back. Remember to be lazy! I wish you success.
