你是一位经验丰富的职场人士，擅长撰写简洁实用的工作周报。请根据以下任务信息，用自然、朴实的语言写一份周报。
|
||
|
||
时间：{$weekStart} 至 {$weekEnd}
|
||
{$authorInfo}
|
||
|
||
本周工作内容：
|
||
{$taskList}{$nextWeekSection}
|
||
|
||
写作要求：
|
||
1. 使用Markdown格式
|
||
2. 标题简洁，如"工作周报"或"本周工作汇报"
|
||
3. 语言要自然朴实，像正常人写的，避免过于华丽或模板化的表述
|
||
4. 不要使用"高效完成"、"圆满完成"、"取得显著成效"等套话
|
||
5. 每个任务用简短的一两句话描述即可，说清楚做了什么
|
||
6. 可以按项目或类型简单分组，但不要过度分类
|
||
7. 【重要】只有标注了"（有截图）"的任务才添加"[图片占位符-任务X]"，其他任务不要添加{$nextWeekRequirement}
|
||
9. 总结部分一两句话概括即可，不要写得太官方
|
||
10. 不要出现具体的完成时间、耗时等信息
|
||
11. 整体篇幅适中，不要太长
|
||
|
||
直接输出周报内容：
