建议位置：高3·上；原创能力递进，不等同于学校实际学期/人教版单元。只训练书面英语。每个编号计一道练习；编号内小项不重复计数。
学习目标
- 分层解析含多重修饰和嵌套从句的长句
- 修复逗号拼接、残句和不平行结构
- 在不改变限定范围的情况下压缩或拆分句子
- 在“数字技术、数据与隐私”语境中区分常用词义、搭配并完成新的书面迁移。
核心讲解
1. 四遍读法
第一遍找有限谓语；第二遍标主句主语与核心谓语；第三遍确定从句入口与非谓语归属；第四遍读否定、量词、比较和限定条件。长句压缩不等于删掉 all/some/not/unless 等决定结论的词。 例：The devices that the team tested in homes where internet access was unreliable performed better when they could store data locally. 主句 devices performed better；that…修饰devices；where…修饰homes；when…说明条件。这里 better 是有条件的比较，不是普遍“最佳”。
2. 平行是语法加逻辑平行
The app helps users record expenses, compare prices and plan purchases：三个原形动词并列。不要混成 record…, comparing… and a plan…。Not only accuracy but also privacy matters 中两个名词平行；换到谓语并列时保持相同层级。
3. 标点是边界信号
句号分开完整句；分号连接关系密切的独立分句；冒号可引出解释/列举，但前面通常先完整表达；破折号可补充或突出，不宜泛滥。however 前用句号或分号，后常逗号。限制性定从通常不加逗号；逗号插入语不能让主谓失联。
4. 清晰优先
为减少嵌套，可以先陈述研究对象，再写条件与结果。拆句时保留 who/which 指代，避免 it 不知指设备、数据还是系统。

阅读材料
主题词汇语境：数字技术、数据与隐私
The interface allowed users to work offline when connectivity was poor. Records were later sent to a server, but the design still needed clear rules about consent, retention and deletion. Encryption protected one part of the process; it did not by itself resolve every privacy question. A system that used machine learning to make predictions required human oversight, especially when a recommendation could affect access to a service. Technical capability and permission to use data were separate issues.
例题解析
例 1 The device is inexpensive, however, it requires regular maintenance. → The device is inexpensive; however, it requires regular maintenance. 原句两个独立句仅逗号拼接。
例 2 The report aims to identify risks, improving safety and cost reduction. → …to identify risks, improve safety and reduce costs。三项都为目标动作。
例 3 Not every device that stores data locally is secure. = 并非每个本地存储设备都安全，不是“所有设备都不安全”。
练习
给句子找主干与两层定从：The platform that researchers developed for communities where connections often fail allows users to save messages offline.
改错：The system is useful, it is not suitable for every task. 至少给两种正确改法。
修复平行：The programme encourages students to question claims, checking sources and independent thinking.
准确翻译：Not all of the information collected by the device is necessary for the service.
将下句拆成两句，保留限制：The sensors, which were tested only indoors, appeared reliable when the temperature remained stable.
写45—65词技术说明：某应用可记录开支、分类购买、显示月度汇总；它不能判断每项购买是否必要，用户仍需自己决策。至少用一个平行结构和一个恰当句子边界。
【主题词汇·辨义】分析：Records that had been anonymised were aggregated before they were sent to the server. 找主句谓语、定从谓语及时间从句谓语；解释authentication与authorisation。
【主题词汇·迁移】写两句技术说明，含one limitation和human oversight；用平行结构列出三项数据操作，不声称匿名化绝对消除风险。

参考答案与解析
主干 The platform allows users to save messages offline。that researchers developed…修饰platform，that作developed宾语；where connections often fail修饰communities，where为地点状语。不能把connections当主句主语。
The system is useful, but it is not suitable for every task. / The system is useful; it is not suitable for every task. / The system is useful. However, it is not suitable for every task. 关系为让步转折，不能随意换because。
The programme encourages students to question claims, check sources and think independently. 三项同受to支配，都是原形动词短语。
设备收集的信息并非全部都是提供该服务所必需的。Not all为部分否定；collected by…修饰information，不能译成“完全没有信息是必要的”。
The sensors were tested only indoors. They appeared reliable when the temperature remained stable. 必须保留only indoors和温度条件；不可改成“The sensors were reliable everywhere”。
示例：The app helps users record expenses, classify purchases and view a monthly summary. These features make spending patterns easier to examine, but they do not establish whether every purchase was necessary. Users still need to consider their own priorities and make the final decisions about their own spending. 量规10：三功能3；能力限制2；用户决策1；平行结构2；边界/语言2。
主句were aggregated；定从had been anonymised修饰records；时间从句were sent。authentication核实“你是谁”，authorisation决定“你获准做什么”，核实身份不自动获得所有数据权限。
示例：The system can collect, organise and summarise records, but incomplete data may limit its predictions. Human oversight remains necessary before those predictions are used to make decisions about individuals. 要点：平行动词；限制具体；人工监督不被“自动化”取代。
