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
按搭配和语境区分常见词的多个义项及近义词。
把口语化或夸大的句子改成得体、准确的书面表达。
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
会背汉语意思不等于会用。address可作“地址”，也可作动词“处理”：The report addresses the shortage of study spaces；issue可作“议题”，issue a notice则是“发布通知”；account可指账户，account for意为“解释／占比例”；charge a fee是收费，be in charge of是负责。阅读时先问词性，再问搭配，最后看篇章话题。
近义词不是任意替换
- rise是不及物：Prices rose. raise通常及物：The shop raised its prices. 过去式分别rose、raised。
- affect常为动词影响：Noise affects concentration. effect常为名词结果：Noise has an effect on concentration。本课不把少见动词effect混进基础选择题。
- economic与经济相关：economic growth；economical节省的：an economical heating system。
- sensible明智的；sensitive敏感的。a sensible plan与sensitive personal information不能互换。
- provide somebody with something / provide something for somebody；不能照中文写provide somebody something用于本课程的规范目标句。
语域与证据强度
给朋友留言可写Thanks for the info；给不熟悉的教师写邮件，可写Thank you for the information。正式不等于把简单词换成最生僻的词：use往往比utilise更直接；buy在普通说明中完全正确。
避免无证据绝对化：The system is perfect and will solve every problem应改为The system may reduce waiting times, although its maintenance costs need further review。修改不是“变长”，而是补出作用范围和限制。词语very good可在具体语境中改为clear、accurate、reliable，而非一律替换为excellent。
例题解析
原句：This cheap plan will definitely fix all the students' problems.
cheap可能只表示便宜，也可能暗含质量低；若证据是“费用低”，可用low-cost。all the students' problems范围过大，先具体化到study-space shortage。若尚未实施，will definitely过强。改为：This low-cost plan could help address the shortage of study spaces. 没有删除对计划的支持，只把支持压到证据允许的程度。

参考答案与解析 · 完成练习后展开
参考答案与解析
1
raised; rose。第一空有宾语the fee，第二空主语cost自行上升；两句为过去时。
2
economic; economical。前者讨论经济发展，后者评价运行是否节省。
3
address是及物动词“回应／处理／顾及”；句意“指南针对一年级学生的需求”。读为“给需求写地址”不合语义。
4
The library provides students with free access to journals. / The library provides free access to journals for students. access通常不可数，常搭配access to。
5
Dear Professor Chen, Could you please send me the course materials when convenient? Thank you for your help. 若并非教授，称谓改为对方已知合适称谓；“ASAP”不能在没有紧急理由时作为礼貌请求的默认结尾。
6
In a survey of 20 volunteers from our class, 12 said they preferred in-person courses. 这只报告样本及偏好，不等于“讨厌网课”，也不能推到everybody或因果prove。
7
affect; effect。may后需动词原形；its exact后需名词。
8
A formal register requires appropriate word choice and a respectful tone, not necessarily obscure words. not necessarily不等于绝不；三个名词块平行。6分：三项意义3，搭配2，句法1。
9
Neutral wording should neither exaggerate the benefits nor understate the difficulties users face. neither…nor后动词原形平行。6分：双方限制3，搭配2，句法1。
