模型未返回最终正文（finish_reason=length），以下为推理过程摘录，可尝试提高 max_tokens 或改用多段生成。

我们需要满足用户要求：输出可直接写入数据库的 HTML 正文片段，仅 <p> 和 <h3>，无 markdown fences，无解释。需要严格顺序：第一个元素 <p> 改写应用介绍，包含应用名。然后小节顺序：软件介绍、优势、使用说明、推荐理由、更新说明、测评。但用户说从词池随机抽3-6个非测评小节，并优先保留采集中有原文者；若含介绍/简介类关键词会固定排在首段 <p> 之后的第一个 <h3>，其余小节再按其下列顺序；末位固定测评，全文共4-7个 h3。但在明确的小节顺序中列出了全部六个：软件介绍 → 优势 → 使用说明 → 推荐理由 → 更新说明 → 测评。好像我们可以输出全部六个非测评小节? 但用户也说已从词池随机抽3-6个非测评小节；但任务列表中又包含了5个非测评小节（软件介绍、优势、使用说明、推荐理由、更新说明），另外测评固定，共6个 h3。这可能意味着我们需要输出全部列出的非测评小节？ Need parse carefully.

User says "【整体结构】顺序必须严格如下： 1) 第一个元素是一个 <p> ... 2) 然后**仅按下列「小节顺序」**输出（已从词池随机抽 **3～6** 个非测评小节并**优先**保留采集中有原文者；若含「介绍」「简介」类关键词会**固定排在首段 <p> 之后的第一个 <h3>**，其余小节再按其下列顺序；末位固定测评，全文共 **4～7** 个 <h3>）：每个小节先 <h3> ..."

Then gives section order: 软件介绍 → 优势 → 使用说明 → 推荐理由 → 更新说明 → 测评. This is a superset of all non-review sections. "已从词池随机抽 3～6 个非测评小节" perhaps in the prompt, but the actual task list includes each section with specific required counts. They likely expect us to output all sections listed in task list because each has a task description and count. However the section list includes all five non-review sections, which is within 3-6? Actually 5 non-review plus 1 review =6 h3, ok. So we should output all five non-review sections plus review. The order specified is software intro, advantages, usage, recommendation, update, review. Good. Need ensure first h3 after intro is "网易云课堂app软件介绍" (contains 介绍) fixed first. Good.

Need content requirements: Each non-review section has <h3>Title</h3> then several <p> each containing one numbered point. Number format: "数字+全角句号．" (e.g., 1．2．3．) at line start. Across whole document same format. Need each <p> contains one point? "每条单独成行，行首为..."; "每 <p> 一条要点". Yes each <p> contains "1．..." etc.

Each section count fixed:
- 软件介绍: 5 p
- 优势: 3 p
- 使用说明: 5 p
- 推荐理由: 6 p
- 更新说明: 5 p
- 测评: 1 p, no numbering, <=200 chars.

Need "首段" <p> rewrite from template. Need include app name naturally. "请参考{组合采集首段}/{原文首段}，现在需要对这段内容进行原创改写，内容必须包含游戏/软件名称，与原文的表达主旨保持高度关联与一致性。可以根据原文的内容进行内容重组，使其逻辑清晰、层次分明，更偏向于一个应用商店的介绍文案。标题：网易云课堂app；原文首段：..." So first p should be an original application store introduction containing "网易云课堂app". Need not use "游戏"? It says software. Should be one <p> paragraph, no numbering. It should mention adult lifelong learning, courses for exams, career, life, one-stop. Maybe: "网易云课堂app是一款面向成人终身学习的综合性在线学习应用，课程覆盖考研升学、英语留学、职场办公、职业考证及生活技能等多个领域，帮助用户一站式解决生活、工作和学习中的成长需求。" That's good. Need avoid markdown. Need ensure first element <p> exists before first h3. Good.

Need write all content. Need ensure each point roughly one sentence under 50 chars? "每条约50字内" Might need keep within 50 Chinese chars. We'll craft concise points.

Let's plan content.

First p:
"网易云课堂app是一款专注成人终身学习的综合性在线学习应用，聚合考研升学、英语留学、职场办公、职业考证与生活技能等丰富课程，为用户一站式解决生活、工作和学习中遇到的成长问题。"

Now h3 软件介绍. Need 5 points. Product positioning, target users, overall ability. Point each <p>:
1．面向成人终身学习场景，提供覆盖学历、职场与生活的系统化课程。
2．聚焦考研升学与英语留学等教育需求，帮助用户提升学业竞争力。
3．内置职场办公和职业考证课程，助力职场人技能进阶与职业发展。
4．包含生活兴趣类内容，满足用户在工作之外的多元化学习需要。
5．以一站式学习平台定位，将多领域优质课程聚合于同一应用之中。

Need each <p> with "1．..." etc. But issue: <p> line break and numbering. Good.

Need "每条约50字" maybe these are ok, around 30-40.

Now h3 优势. 3 points. Performance, ease, compatibility, ecosystem.
1．课程分类清晰，学习路径直观，用户能快速找到所需内容。
2．支持多终端同步学习，账号数据互通，随时随地继续课程进度。
3．平台整合优质教育资源，课程体系完善，满足不同阶段学习者的需求。
Could mention ease of use and ecosystem.

Now h3 使用说明. 5 points. Installation, permissions, account, getting started.
1．在应用商店搜索“网易云课堂app”并下载安装，按提示完成注册。
2．首次使用建议使用手机号或网易邮箱登录，便于同步学习记录。
3．根据学习目标选择课程，可先浏览免费试听内容再决定报名。
4．在个人中心可查看已购课程、学习进度与离线缓存内容。
5．开启通知权限即可接收开课提醒与课程更新消息，避免错过学习。
Need "应用商店" maybe fine. "网易云课堂app" appears in heading. Point 1 includes app name. No other issue.

Now h3 推荐理由. 6 points. Why install, concrete benefits.
1．无需线下奔波即可学习名校名师课程，节省时间与通勤成本。
2．课程覆盖考研、职场、生活等方向，一个应用满足多种提升需要。
3．支持缓存离线观看，通勤或无网络环境下也能随时学习。
4．可按需选择单门课程或系统学习方案，学习投入更灵活。
5．学习进度自动记录，方便制定计划并持续追踪成长效果。
6．新手可先试听体验，再决定是否购买，降低选课决策门槛。

Need "具体收益".

Now h3 更新说明. 5 points. Version new features, optimization, fixes, no version history.
1．新增个性化学习推荐，根据学习记录智能匹配更适合的课程。
2．优化课程播放体验，提升视频加载速度并减少播放卡顿。
3．完善学习进度管理功能，可更清晰地查看已完成与待学内容。
4．修复部分已知问题，提升应用在不同设备上的运行稳定性。
5．改进搜索与筛选能力，帮助用户更快找到目标课程和学习资料。

Need maybe "本版本" but okay.

Now h3 测评. One <p> continuous, no numbering, <=200 chars. Need objective. "网易云课堂app测评" heading. Then paragraph:
"网易云课堂app以成人终身学习为核心，课程覆盖从升学考研到职场技能的多元场景，平台内容扎实且分类清晰。实际使用中，学习进度同步和离线缓存功能让碎片时间得到充分利用；推荐系统与试听机制也降低了选课门槛。整体而言，它是一款兼顾实用性与成长价值的在线学习工具，适合希望持续提升自我的用户长期使用。"
Count maybe 156? Let's count roughly. Need <=200. Good.

Need ensure "最后一个小节固定为「网易云课堂app测评」" In heading exactly "网易云课堂app测评". Good.

Need no markdown code fences, no explanations. Output should start with <p> directly. Need no outer html.

Need ensure all sections with <h3> heading exactly as specified. Yes.

Need consider "数字+全角句号．" There is a subtle: Unicode U+FF0E? Actually "．" is fullwidth full stop? Chinese number + fullwidth dot. Examples "1．2．3．" This is a fullwidth dot at baseline, not U+3002 "。" Need use "．" (U+FF0E FULLWIDTH FULL STOP). Good. Need after number no space? "1．" yes.

Need ensure each <p> contains "1．..." not "1. " with ASCII. Good.

Need "全篇统一为同一种序号格式" so all sections use same. Good.

Need "每条单独成行" In HTML, each <p> is separate. Good.

Need "首段模板 {head}/{text}" We did.

Need "若含「介绍」「简介」类关键词会固定排在首段 <p> 之后的第一个 <h3>" Our first h3 is 软件介绍, good. Then others in order.

Need "已从词池随机抽 3～6 个非测评小节" We are outputting all five non-review sections. But "非测评小节" count 5, within 3-6. Good. But "仅按下列「小节顺序」输出" includes all six; okay.

Need "全文共 4～7 个 <h3>" We have 6. Good.

Need "每个小节先 <h3>，非「测评」小节为 若干 个 <p>" We have all.

Need "每节要点条数以该小节下方【条数】为准" We have exact.

Need "首段 <p> 正文中自然出现应用名称" We have.

Need "禁止输出 <img>" none.

Need "允许的 HTML 标签仅有：<p>、<h3>" We use only.

Need "不要输出 <html><body> 等外壳" none.

Need "禁止 markdown 代码围栏" no.

Need "测评 仅 1 个 <p>，不要序号与分条" yes.

Need "全文不超过200字（含标点）" Specifically for the 测评 paragraph? It says "「测评」小节：仅 1 个 <p>，不要序号与分条，一段短评，全文不超过 200 字（含标点）" The "全文" in that bullet likely refers to the 测评 paragraph, not whole document. Need ensure the 测评 paragraph <=200. We have. Whole document much longer but allowed. Good.

Potential issue: The user says "每条一句、每条约50字内" for each point. Need check our points lengths. Let's count some:
软件介绍 point 1: "面向成人终身学习场景，提供覆盖学历、职场与生活的系统化课程。" 29? Good.
Point 2: "聚焦考研升学与英语留学等教育需求，帮助用户提升学业竞争力。" 28.
Point 3: "内置职场办公和职业考证课程，助力职场人技能进阶与职业发展。" 28.
Point 4: "包含生活兴趣类内容，满足用户在工作之外的多元化学习需要。" 27.
Point 5: "以一站式学习平台定位，将多领域优质课程聚合于同一应用之中。" 28.

优势:
1 "课程分类清晰，学习路径直观，用户能快速找到所需内容。" Around 24.
2 "支持多终端同步学习，账号数据互通，随时随地继续课程进度。" 26.
3 "平台整合优质教育资源，课程体系完善，满足不同阶段学习者的需求。" 29.

使用说明:
1 "在应用商店搜索“网易云课堂app”并下载安装，按提示完成注册。" Actually includes app name, 24.
2 "首次使用建议使用手机号或网易邮箱登录，便于同步学习记录。" 25.
3 "根据学习目标选择课程，可先浏览免费试听内容再决定报名。" 25.
4 "在个人中心可查看已购课程、学习进度与离线缓存内容。" 24.
5 "开启通知权限即可接收开课提醒与课程更新消息，避免错过学习。" 27.

推荐理由:
1 "无需线下奔波即可学习名校名师课程，节省时间与通勤成本。" 24.
2 "课程覆盖考研、职场、生活等方向，一个应用满足多种提升需要。" 26.
3 "支持缓存离线观看，通勤或无网络环境下也能随时学习。" 24.
4 "可按需选择单门课程或系统学习方案，学习投入更灵活。" 24.
5 "学习进度自动记录，方便制定计划并持续追踪成长效果。" 24.
6 "新手可先试听体验，再决定是否购买，降低选课决策门槛。" 25.

Update:
1 "新增个性化学习推荐，根据学习记录智能匹配更适合的课程。" 25.
2 "优化课程播放体验，提升视频加载速度并减少播放卡顿。" 24.
3 "完善学习进度管理功能，可更清晰地查看已完成与待学内容。" 25.
4 "修复部分已知问题，提升应用在不同设备上的运行稳定性。" 24.
5 "改进搜索与筛选能力，帮助用户更快找到目标课程和学习资料。" 26.

Good.

Need maybe "网易云课堂app" in first p and first h3? first p includes. Good.

Need "应用商店的介绍文案" We wrote.

Need "与原文的表达主旨保持高度关联与一致性" yes.

Need "全局说明 rewriteKeys = [推荐理由 更新说明]" This was for multi-segment? We can use tone reference; no need.

Need "禁止任何解释或前言后记" We just output content.

Need maybe "标点" "．" counts as punctuation. okay.

Need "H3title" for 软件介绍 includes <h3>网易云课堂app软件介绍</h3>. Good.

Potential issue: The tag "网易云课堂app" maybe should be "网易云课堂" (official name?) User insists application name "网易云课堂app" and title. We'll use exactly.

Need "游戏/软件名称" says include software name; okay.

Let's consider if outputting all five non-review sections violates "随机抽3～6个" perhaps maybe not. But user "各小节任务" includes each with "【条数】" and "按「原创H3-普通」撰写". The likely expected output includes all six sections, because the task builder includes all. We can output them all. If only random subset selected, why list all tasks? Because user says "已从词池随机抽 3～6 个非测评小节" but the given prompt includes all sections? Wait maybe "词池" in the system could have selected all four? Let's parse: "然后**仅按下列「小节顺序」**输出（已从词池随机抽 **3～6** 个非测评小节并**优先**保留采集中有原文者；若含「介绍」「简介」类关键词会**固定排在首段 <p> 之后的第一个 <h3>**，其余小节再按其下列顺序；末位固定测评，全文共 **4～7** 个 <h3>）" Then after that, "小节顺序：软件介绍 → 优势 → 使用说明 → 推荐理由 → 更新说明 → 测评" This could mean the "小节顺序" is the full ordering template, not necessarily the selected subset. But then they provide "各小节任务" for all 5 non-review sections, each with "条数". The model is expected to output all sections that appear below. They didn't explicitly say "仅输出以下小节" but "仅按下列「小节顺序」输出" means output according to order. Since all sections listed, output all. The parenthetical about 3-6 random non-review sections might be from higher-level template, but we ignore? Actually the user says "已从词池随机抽 3～6 个非测评小节" and then "优先保留采集中有原文者" but here all sections are "无对应采集原文". Maybe the "词池随机抽" is not something we decide. The "各小节任务与已代入模板" lists all five, so I think output all five. The final count 6 h3 is within 4-7, so okay.

Need "软件介绍" first h3 due to "介绍" fixed. Good.

Need "测评" final. Good.

Potential issue: The "首段" first p should maybe contain "标题：网易云课堂app"? No, title is not part of body. We include app name.

Potential issue: "禁止输出 <img>（应用截图由系统在生成后按小节顺序自动插入，模型无需处理图片）" no images.

Potential issue: Need no "script/style" no.

Potential issue: Should each non-review section's numbered points be in separate <p> or could be all in one <p> with <br>? User says 每条单独成行，行首为...; "每个小节先 <h3>，非「测评」小节为 若干 个 <p>、每条要点须带序号" and "每 <p> 一条要点" in tasks. So yes separate <p> per point. Good.

Potential issue: In HTML, "1．" inside <p> is fine. Need no <br>. Good.

Potential issue: "全文不超过 200 字（含标点）" for the 测评 paragraph. Let's count exactly to be safe. Our测评 paragraph:
"网易云课堂app以成人终身学习为核心，课程覆盖从升学考研到职场技能的多元场景，平台内容扎实且分类清晰。实际使用中，学习进度同步和离线缓存功能让碎片时间得到充分利用；推荐系统与试听机制也降低了选课门槛。整体而言，它是一款兼顾实用性与成长价值的在线学习工具，适合希望持续提升自我的用户长期使用。"
Count Chinese chars and punctuation? Let's count: 
1 网 2 易 3 云 4 课 5 堂 6 a 7 p 8 p? Actually "app" counts? Usually not important. Let's count chars maybe 156. Good.

Need perhaps avoid semicolon? Punctuation ok.

Need ensure no numbering in测评. yes.

Need "拟人化叙述方式" Hmm user says "尽量拟人化的叙述方式" in测评 template. Our paragraph is objective, not heavily personified. Could adjust to be more natural, maybe "它像一位随时待命的学习伙伴". Need satisfy? Let's see: "请根据上文中对网易云课堂app的内容介绍，原创一篇200字左右的的评测，需要结合内容中对于网易云课堂app的特色、亮点、推荐理由等部分进行一个客观的评价，保证语句通顺流畅，尽量拟人化的叙述方式。" We should include some personification. Our current is not personified. Let's rewrite测评 to include "它" but that's just pronoun. Maybe "网易云课堂app像一位沉稳的终身学习伙伴，把成人成长所需的课程稳稳地汇集在身边。..." Let's craft with personification and objective. Need still <=200. Example:
"网易云课堂app像一位可靠的终身学习伙伴，围绕升学、职场与生活场景备好全程课程，内容扎实且分类清晰。实际体验中，学习进度同步、离线缓存等功能让碎片时间也能高效利用，试听与推荐机制则让选课更从容。整体来看，它把庞杂的学习需求整理成清晰的进阶路径，值得希望持续成长的用户长期相伴。"
This is more personified. Count ~150. Good. Need "结合特色、亮点、推荐理由" yes. We'll use this.

Need perhaps "app" in first p? yes.

Need consider "软件介绍" section "本节写作侧重：产品定位、目标用户与整体能力概述." Our points align.

Need "优势" "性能、易用性、兼容性或生态" yes.

Need "使用说明" "安装、权限、账号与基础上手要点" yes.

Need "推荐理由" "为何值得安装使用，需落到具体收益" yes.

Need "更新说明" "本版本新增、优化与修复要点" yes.

Need "测评" "only one p, no numbering" yes.

Let's think if "唯一允许 HTML tags <p>, <h3>" and "禁止输出 <img>" okay.

Need maybe no blank lines? We can output with blank lines? Not necessary. "直接写入数据库" maybe blank lines okay but maybe safe to output raw HTML with newlines between tags, no extra code. We can output as:
<p>...</p>
<h3>...</h3>
<p>1．...</p>
...
This is acceptable.

Need avoid any Markdown fences. We won't.

Need perhaps "首段" should be "请参考{组合采集首段}/{原文首段}" The first p should not include "组合采集首段" literally. We'll not.

Need "标题：网易云课堂app；原文首段：..." Maybe the title is not part of body; but we include in heading tags.

Potential issue: The user said "应用名称（须在首段 <p> 正文中自然出现）：网易云课堂app" and "标题：网易云课堂app" We include.

Need maybe "成人终生学习" vs "成人终身学习"? Original says "终生学习". "终身学习" more standard. Our first p uses "终身". Is that okay? "与原文表达主旨保持高度关联" yes. Could use "终生" to be closer. Use "成人终身学习" not issue. But to be safe, use "成人终生学习"? Original "终生学习". But standard is "终身学习". Both ok. We'll maybe use "终身" because common. But user explicitly says "终生学习" in original. Should we preserve? "网易云课堂app是一款专注成人终生学习的应用" we can use "终生". But "终身学习" equally. Hmm "终生" means lifelong, "终身" also. For high association, use "终生" perhaps. Let's decide. First p:
"网易云课堂app是一款专注成人终生学习的综合性在线学习应用，聚合考研升学、英语留学、职场办公、职业考证与生活技能等丰富课程，为用户一站式解决生活、工作和学习中遇到的成长问题。"
This preserves "终生". Good.

Need "首段" maybe should "含游戏/软件名称" yes.

Need no "应用名称：" etc. yes.

Need "全文共 4～7 个 <h3>" We have 6, good.

Need "非「测评」小节为 若干 个 <p>、每条要点须带序号且**全篇统一为同一种序号格式**" yes.

Potential issue: The number formatting "1．" uses fullwidth dot. Some systems may not want numbers? We use. Good.

Need "每节要点条数" independent. yes.

Need maybe "软件介绍" section should be "若干 个 <p>" but "固定 5 条" yes.

Need maybe "测评" section "全文不超过200字" Could check our revised personified paragraph length:
"网易云课堂app像一位可靠的终身学习伙伴，围绕升学、职场与生活场景备好全程课程，内容扎实且分类清晰。实际体验中，学习进度同步、离线缓存等功能让碎片时间也能高效利用，试听与推荐机制则让选课更从容。整体来看，它把庞杂的学习需求整理成清晰的进阶路径，值得希望持续成长的用户长期相伴。"
Count: Let's count with punctuation perhaps:
1网 2易 3云 4课 5堂 6a 7p 8p 9像 10一 11位 12可 13靠 14的 15终 16身 17学 18习 19伙 20伴 ，(21) 22围 23绕 24升 25学 、26职 27场 28与 29生 30活 31场 32景 33备 34好 35全 36程 37课 程38，39内 40容 41扎 42实 43且 44分 45类 46清 47晰 。48实 49际 50体 51验 52中 53，54学 55习 56进 57度 58同 59步 60、61离 62线 63缓 64存 65等 66功 67能 68让 69碎 70片 71时 72间 73也 74能 75高 76效 77利 78用 79，80试 81听 82与83推 84荐 85机 86制 87则 88让 89选 90课 91更 92从 93容 94。95整 96体 97来 98看 99，100它 101把 102庞 103杂 104的 105学 106习 107需 108求 109整 110理 111成 112清 113晰 114的 115进 116阶 117路 118径 119，120值 121得 122希 123望 124持 125续 126成 127长 128的 129用 130户 131长 132期 133相 134伴 135。 Count 135 or 143 including punctuation. Fine.

Need maybe "测评" should be "短评收束全文" not too formal. Good.

Now, let's think if "软件介绍" with 5 points should be more "应用商店介绍文案" style. Good.

Potential issue: The first point in 使用说明 says "在应用商店搜索“网易云课堂app”并下载安装，按提示完成注册。" But one usually registers after first open, not before. Fine.

Need maybe "支持多终端同步学习" is "生态" / "兼容性" yes.

Need maybe "推荐理由" "可先试听体验" is repeated in 使用说明 point 3 "可先浏览免费试听内容再决定报名" and 推荐理由 point 6. Is repetition okay? Could adjust to avoid duplicate across sections. In 使用说明, "选择课程" perhaps okay. In 推荐理由, "降低选课门槛" maybe okay but duplicates. Need not be overly concerned. But to be polished, vary:
使用说明 3: "进入课程详情页可查看大纲与免费试听内容，了解后再开始学习。" This avoids "决定报名".
推荐理由 6: "提供免费试听和课程评价参考，帮助新手做出更合适的选课决策。" Good. Let's adjust.

Similarly "学习进度同步" appears in 优势 point 2 and 推荐理由 point 5 and 测评. It's a common feature; okay.

Need maybe "更新说明" "新增个性化学习推荐" and "推荐机制" in测评 okay.

Need maybe "首段" and "软件介绍" both say "一站式" but okay.

Need "标题必须与 {H3title} 完全一致" ensure exact:
<h3>网易云课堂app软件介绍</h3>
<h3>网易云课堂app优势</h3>
<h3>网易云课堂app使用说明</h3>
<h3>网易云课堂app推荐理由</h3>
<h3>网易云课堂app更新说明</h3>
<h3>网易云课堂app测评</h3>
Yes.

Need "应用名称" maybe "网易云课堂app" is all lowercase "app"? User specifies. yes.

Potential issue: "首段 p" perhaps "原文首段" includes "网易云课堂app是一款专注于成人终生学习的应用..." We can use "是一款" too. But "原创改写" not duplicate. Good.

Let's now think about "全篇统一为同一种序号格式" in all non-review sections. We use "1．" etc. For each section, numbering restarts at 1, not continuous. Is that okay? The user says "用序号分条：每条单独成行，行首为「数字+全角句号．」（示例 1．2．3．），全篇保持同一格式". In each section, naturally numbering restarts? They don't explicitly require continuous numbering across sections. "本节须写 5 条" implies within section numbers 1-5. So yes.

Need maybe "多个 <p> 每条单独成行" If numbering restarts, no issue.

Need maybe "全篇统一为同一种序号格式" not "全篇连续编号". Good.

Potential issue: "小节【条数】" for software intro says 5, advantages 3, usage 5, recommendation 6, update 5. We have.

Need "优先保留采集中有原文者" Here no original for each non-review, but we use original first paragraph for all. Fine.

Need "rewriteKeys（入库多段链路中曾用于抽两段深度重写；整篇一次生成时可作语气参考）=[推荐理由 更新说明]" We don't need to mention. Good.

Let's consider if "随机抽 3～6 个非测评小节" maybe means "do not output all sections"? If we output all five non-review, is that "3-6"? It's 5, so not invalid. But "已从词池随机抽" maybe "selected" by system, and "only output selected sections" but no explicit selected list except the full order. The "各小节任务" all included with original. Could there be a hidden expectation to output only those sections for which task blocks appear? All five task blocks appear. So output all.

Need perhaps "小节顺序" includes "软件介绍 → 优势 → 使用说明 → 推荐理由 → 更新说明 → 测评" exactly. We follow.

Need "应用截图由系统在生成后按小节顺序自动插入，模型无需处理图片" no images.

Need "禁止输出 <img>" no.

Need maybe "不要 script/style" no.

Need "输出必须为一段连续中文" in测评 only. Our测评 is one paragraph. Good.

Potential issue: "只输出一段可直接写入数据库的 HTML 正文片段" The entire output is a fragment with multiple tags, "一段" perhaps means "a section" not a single paragraph. okay.

Let's refine content to avoid any "分数" or "数字" issues. Good.

Let's craft final output exactly:
