The user wants a Chinese SEO article about "北京老年大学". The output format is strict:

• First line: "# 标题文字". Must be a single #, space, then title. Title must contain "北京老年大学", 15-25 characters, no numbering, no emoji. Must target elderly or their children, use words like "避坑", "全攻略", "免费", "丰富晚年". Structure can be question, experience, numeric.

• Second line: article summary: 50-70 Chinese characters, complete sentence, summarizing core, friendly and stable tone, attract elderly.

• After summary, third line output: "" (two backticks?) Actually they wrote: 摘要后第三行输出：，然后再开始正文。 Means after the summary, third line output: `` (two backticks). Then start the body. So we need to output a line with two backticks, then start the article.

• Then article content: Must follow structure based on "北京老年大学" specific attributes. The user gave three categories: 课程/报名类, 择校/避坑类, 心理/价值类. We need to choose one? The user says "根据“北京老年大学”的具体属性，自动识别并采用以下结构". So we need to decide which structure fits best. The article is about "北京老年大学" as a whole, likely covering courses, registration, selection, and value. Could combine multiple. But they gave three possible structures: 1. 课程/报名类: core logic: clear registration process (1.2.3...), emphasize "零基础也能学". Must include a simple fee or lesson table. Must include health reminder for sports courses.

2. 择校/避坑类: hardware indicators: emphasize barrier-free facilities, first aid kits, distance from home. Reputation: teach how to see teacher strength and past exhibitions.

3. 心理/价值类: social needs: describe how elderly university solves loneliness, emphasize "老有所乐". Tech: mention smartphone, short video courses.

We need to incorporate at least one of these. The article could be a comprehensive guide covering all three aspects. But the user says "根据“北京老年大学”的具体属性，自动识别并采用以下结构". That suggests we need to pick the most appropriate structure. Since the article is about "北京老年大学", likely it's a guide for elderly to choose and register. So we could adopt the 课程/报名类 structure, but also incorporate selection criteria and value. However the structure is defined: "核心逻辑：明确报名流程（1.2.3...），强调“零基础也能学”，费用透明：必须包含一个简单的费用或课时表格，展示不同课程的参考标准，健康提醒：针对舞蹈、太极等体育类课程，必须加入“运动强度建议”。"

Thus we need to include a registration process, emphasize zero-basis, include a fee table, include health reminder for sports.

We also need to incorporate hardware indicators and reputation for selection, maybe as part of the article.

We also need to incorporate social needs and tech.

But the user says "根据“北京老年大学”的具体属性，自动识别并采用以下结构". Possibly they want us to choose one of the three structures. But they also gave content depth requirements: "真实感：每篇文章必须包含至少1处具体数据（如：平均每学期学费区间、建议上课天数、某类课程的平均年龄段），问答环节：文章末尾设置3个“老友最关心的问题”，采用“现象 + 原因 + 专家建议”结构，图文布局：多用 Markdown H2/H3 标题，重点信息加粗。"

Thus we need to produce an article with at least one specific data, a Q&A at the end with three questions, each with phenomenon, cause, expert suggestion. Use Markdown H2/H3 headings, bold important info.

We must avoid ", ", ". Use gentle, patient, professional tone.

We must include core keyword "北京老年大学" at least once in first paragraph, middle, and end. Also naturally embed related long-tail keywords like "社区老年教育", "退休生活规划". Use year 2026.

We must include a fee table. Possibly include a simple table with columns: 课程类别, 平均学费 (元/学期), 课时 (节/学期), 适合年龄段.

We must include health reminder for sports courses: "运动强度建议：建议根据个人身体状况选择适度强度，如太极拳轻度、舞蹈中等强度等".

We must include registration steps: maybe 1. 了解课程设置 2. 线上/线下报名 3. 缴费 4. 开学前准备.

We must include hardware indicators: barrier-free facilities, first aid, distance.

We must include reputation: teacher qualifications, past exhibitions.

We must include social need: solving loneliness, "老有所乐".

We must include tech: smartphone, short video.

We must include Q&A at end: three questions.

We must include "本文仅供参考，具体课程及报名政策以校方最新公告为准" at the end.

We must include the line with two backticks after summary.

We must ensure first line is exactly "# 标题文字". Title must be 15-25 Chinese characters, include "北京老年大学". Must target elderly or children, use "避坑", "全攻略", "免费", "丰富晚年". Could be something like: "北京老年大学全攻略：零基础也能学，选课避坑指南". That is 19 characters? Let's count: "北京老年大学全攻略：零基础也能学，选课避坑指南". Count characters: 北京(2)老年(2)大学(2)全(1)攻略(2)：(punct) maybe not count? Let's count Chinese characters ignoring punctuation: 北京老年大学全攻略零基础也能学选课避坑指南. That's 2+2+2+1+2+3+2+2+2+2+2 = 22? Let's count precisely: "北(1)京(2)老(3)年(4)大(5)学(6)全(7)攻(8)略(9)零(10)基(11)础(12)也(13)能(14)学(15)选(16)课(17)避(18)坑(19)指(20)南(21)". That's 21 characters. Good. It includes "北京老年大学", "全攻略", "避坑". Also "零基础也能学". Good.

But we need to ensure it's 15-25 characters. 21 is okay.

Alternatively we could do "退休后去北京老年大学学什么？全攻略免费指南". That's 19? Let's count: 退休后去北京老年大学学什么全攻略免费指南. That's maybe 18? Let's count: 退(1)休(2)后(3)去(4)北(5)京(6)老(7)年(8)大(9)学(10)学(11)什(12)么(13)全(14)攻(15)略(16)免(17)费(18)指(19)南(20). That's 20. Good. But includes "全攻略", "免费". But we also need "北京老年大学". It appears. Good.

But we also need to target "老年人或其子女的痛点". The title could be "北京老年大学选课避坑指南：零基础也能学，丰富晚年生活". Let's count: 北京老年大学选课避坑指南零基础也能学丰富晚年生活. That's maybe 22? Let's count: 北1京2老3年4大5学6选7课8避9坑10指11南12零13基14础15也16能17学18丰19富20晚21年22生23活24. That's 24 characters. Good. It includes "北京老年大学", "避坑", "零基础也能学", "丰富晚年". Good.

But we need to ensure no emoji, no numbering. Title must be exactly one #, space, then title. So we will output "# 北京老年大学选课避坑指南：零基础也能学，丰富晚年生活". That's 24 characters? Let's count again: "北京老年大学选课避坑指南：零基础也能学，丰富晚年生活". Excluding punctuation maybe count Chinese characters only: 北京老年大学选课避坑指南零基础也能学丰富晚年生活. Let's count: 北1京2老3年4大5学6选7课8避9坑10指11南12零13基14础15也16能17学18丰19富20晚21年22生23活24. So 24 characters. Good.

Now summary: 50-70 Chinese characters, complete sentence, friendly. Let's craft: "本文为老年朋友们系统梳理北京老年大学的课程种类、报名流程、费用标准及选校关键要点，帮助零基础学员轻松入门，避免常见陷阱，享受充实晚年学习生活。" Let's count characters: 本文为老年朋友们系统梳理北京老年大学的课程种类报名流程费用标准及选校关键要点帮助零基础学员轻松入门避免常见陷阱享受充实晚年学习生活.

That's 65 characters. Good, within 50-70. It's a complete sentence. Good.

Now after summary, we need to output a line with two backticks. The instruction: "摘要后第三行输出：，然后再开始正文。" Means after the summary, third line output:. So we need to output a line containing two backticks. Possibly just "``". Then start the article.

Thus output:

Line1: # 北京老年大学选课避坑指南：零基础也能学，丰富晚年生活

Line2: 本文为老年朋友们系统梳理北京老年大学的课程种类、报名流程、费用标准及选校关键要点，帮助零基础学员轻松入门，避免常见陷阱,享受充实晚年学习生活。

温馨提示：报名体育类课程前，请先进行体检，确保身体状况适合相应运动强度，如有慢性疾病,请提前告知授课老师。

择校与硬件指标

硬件设施：安全与便利并重

• 无障碍通道：校园内设有坡道、扶手、升降梯,方便轮椅使用者自由出入。

• 教室设施：配备空调、暖气、护眼灯光，课桌椅高度可调,符合老年人体工学。

口碑辨别：师资与展演

心理价值与社交需求

科技融入：智能手机与短视频

• 智能手机课程：从基础操作到微信支付、健康码使用,帮助老年人跨越数字鸿沟。
