三、模板应用解析
1. 投诉信：开头直接点明问题（如商品质量），主体用数据事实支撑（订单号、问题细节），结尾强调解决诉求。

3. 邀请信：开头说明活动意义，主体突出嘉宾重要性（Your expertise in...），结尾附日程安排。
4. 告示：标题需醒目，内容用短句分点（bullet points），关键信息加粗（如Deadline: Jan 10）。
四、考场要点
1. 称呼格式：陌生用Dear Sir/Madam，已知用Dear Prof. Wang，结尾必加逗号。
2. 字数控制：答题卡约12行，建议写满10行，少用长复合句。
3. 错误规避：避免缩写（如can’t）、口语词（如guy），检查第三人称单数动词。
