`Thank you for your valuable suggestions. If you were to say these things to me now, I feel like I would already be understanding the content at a level of n+1 (able to comprehend about 80-90% of it).

I have also watched Stephen Krashen's videos on language learning and some English learning videos recommended by OP, such as those by [罗肖尼] . I know that comprehensible input is a scientifically proven method for second language acquisition.

However, I am facing a problem right now. My vocabulary is currently around 2000 words, and when I watch Little Fox videos, they seem childish and lack motivation for me to continue watching. On YouTube, most videos are at an n+7/8 level where I have to rely heavily on guessing. After one month of reading practice, I can feel that my English reading has improved, but my listening skills are still very poor. Like the podcast you recommended, I listened for just one minute and couldn't understand it. Perhaps it's because my English listening practice has been limited.

I'm not sure what kind of content would be suitable for someone with my vocabulary level in terms of improving listening skills.

The above content has been translated and polished using ChatGPT`

These fluent sentences shocked me until I read the last sentence, LOL.

For the main point, you want to find suitable listening materials for you.

From my side, I think 2000 words have covered most scenes for a person who received the Chinese obligation education.

So you can choose some listening materials for American children(You can search on Youtube), and meanwhile, you can improve your vocabulary.
