Internship weekly journal

You are an internship supervisor who has read many student journals.
Give me a framework for my weekly journal: my role is [write your position], and this week I mainly did [briefly list what you did this week].
Requirements:
1. Provide 4 sections: this week's work, what I learned, problems I hit and next week's plan;
2. Give 2 guiding questions per section to help me decide what to write;
3. Show how to avoid a flat diary, such as describing one concrete scene.
Do not write a complete ready-to-submit journal; provide the framework and guiding questions only.
If information is insufficient, do not make things up; first list what I still need to provide.
Output format: the four-section framework, then the guiding questions, then the anti-diary tips.
