找到了一个讲语言学习的视频，博主很厉害，掌握了多门不同语系的语言。这个视频主要讲英语母语者如何从零开始学外语，但中文母语者学英语、二外也可以参考，只不过大纲上的内容需要做相应调整。
该视频给出的学习技巧的重点是用 comprehensible input 替代死板的 word memorize 和 grammar study。与本人情况适配的大纲总结如下：
- Comprehensible input
- e.g. story listening
- Don't study grammar
- You don't have time to think about correctness before you say the sentence
- Thinking about grammar first prevents you from fluency
- Learn grammar after you can speak fluently
- Find the right class
- The natural approach: no grammar, no correction, no other language
- TPRS: teaching proficiency through reading and storytelling
- Find the right instructor
- Things that are easy to understand
- Decide the language and time (Depending)
- Don't spend your time on reading and writing, listen and speak!
- Find language partners
- Friends, coworkers, language consults; language exchange; APPs…
- The magic
- Magazines: picture, ask what's this/ what is she doing/ why…
- Children's stories: retell the stories
- TPR(Total physical response)
- Ask your partner to give you a list of commands, verbs, or actions
- Read to learn grammar smoothly
- Input + 1
- Input you already know + something ramping up
- Repeat the recordings
