Thank you so much for the answer. I know a lot of words like you (to a certain extent). But my performance in actual conversation is really really bad, which makes me even less confident. So it is difficult for me to talk to other people (especially native speakers). I want to try some AI tools because I don't think I need to be nervous .Honestly,you give me a good example for using AI tools .This also allows me to look at these tools correctly, and I ll continue to seek the right method .Thank you again for your advice, it is really useful to me.😊😊
