本课为原创大学书面英语能力课程，不对应统一的人教版大学教材或固定大学年级；不含听力。练习目标只反映本站材料掌握情况，不保证实际考试分数。
学习目标
写出主题明确、背景充分、请求可执行且语气得体的邮件。
在咨询、延期和投诉场景中说明事实与下一步，不捏造承诺或情绪攻击。
在本课主题中理解新增词块的语境用法，并把其中相关词项迁移到新的完整句子。
核心讲解
邮件结构：Subject说明任务；称呼符合已知关系；首段说目的；中段给必要事实；末段提出可执行请求和感谢；署名。礼貌不是无限绕弯，“Could you clarify…”通常比“I am writing this email with the purpose of wanting to…”清楚。
称谓不确定可用Dear Course Team或Hello，不凭空给对方教授头衔。不要只写Dear teacher。请求截止时间须说明原因，可写If possible, could you reply by Thursday so that…；ASAP不是默认礼貌用法。
原创示范：咨询任务范围
Subject: Clarification of the summary assignment
Dear Course Team,
I am preparing the summary assignment due on Friday and would like to clarify one requirement. The instructions ask us to compare two sources, but the example on the course page discusses only one.
Should the final summary include both sources, or should we choose one and mention the other briefly? I have drafted an outline for a two-source comparison and can adjust it if necessary.
If possible, I would appreciate clarification by Wednesday so that I have time to revise. Thank you for your help.
Best regards, Lin
这封信说明矛盾位置、已做工作和明确问题，不责备对方“说明糟糕”。姓名为课程范例。
延期与投诉
申请延期应说真实原因、目前进展、请求新时间；不能把“请求”写成“你已批准”。投诉列出日期、订单/服务事实、影响和期望解决办法，不写无依据的违法或欺骗指控。若只是学习写作，可用虚构场景并明确它是练习。
例题解析
过强：You must reply immediately because your instructions make no sense.
改：Could you clarify whether the word limit includes the references? The two versions of the instructions give different limits. 明确可答的问题比攻击有效；如确有时间约束再加合理期限。

参考答案与解析
1
Subject: Weekend rules for study-room bookings。需写weekend和booking，不要只写Question或Help。
2
Could you please send me the file so that I can check the figures before our meeting? 用途具体；不凭空添加真实期限。
3
补齐事项、原时间、请求新时间。Could we move the project review from this Friday to next Monday? I need another day to verify the figures. 已是请求而非单方面宣布。
4
Subject: Request for a short extension
Dear Course Team,
Our group has completed the main text of the report, but we need to verify one figure before submitting it. The original source gives two different totals, and we do not want to present an unverified number as a fact.
Would it be possible to extend our deadline from Friday to Monday? We are checking the source now and will complete the final revision as soon as the figure is confirmed. If an extension is not possible, please let us know how you would prefer us to handle the uncertain data.
Thank you for considering our request. Best regards, Lin

Subject: Study room unavailable during my booking
Dear Library Team,
I booked Room 2 for [date], from [start time] to [end time]. When I arrived, another activity was using the room, and I could not begin the quiet study session I had planned. My confirmation number is [number].
Could you explain what happened and let me know whether an alternative quiet room is available? I would also appreciate advice on how to confirm that a future booking can be used as scheduled.
Thank you for looking into the problem. Best regards, Lin

The subject line of this courteous enquiry should identify the discrepancy between the two sets of instructions and ask a clear question. 不把discrepancy直接写成故意误导。6分：信息3，词块2，句法1。
7
When requesting a rescheduling, state the proposed deadline clearly rather than treat the request as a confirmation email. 更自然可写When asking to reschedule, clearly state the proposed date and do not assume it has been confirmed. 6分：信息3，搭配2，句法1。
