易混淆点为“访问控制 vs 内容绑定 vs 传统加密”。单纯加密只能防直接打开，密钥泄露即失效；DRM高级形态强调“环境绑定”（CPU/硬盘/OS指纹）。考题常将“密码验证”“次数限制”包装成DRM，需识别其本质仍是传统权限管理，未触及“内容与运行环境强耦合”的DRM核心特征。 <!-- polish:v1 -->
易混淆：身份验证(Authentication) vs 数据加密(Confidentiality) vs 访问控制(Access Control)。验证解决“你是谁”，加密解决“内容不被看”，访问控制解决“你能做什么”。本题专指源头身份真实性，非数据保密或边界防御。 <!-- polish:v1 -->
易混淆：可验证性(Verifiability) vs 不可否认性(Non-repudiation) vs 可用性(Availability)。在CA传密钥语境下，“可验证”侧重来源真实可信；“不可否认”侧重事后追责；“可用”侧重系统正常运行。本题特指传输过程中的信任建立，故选可验证性。 <!-- polish:v1 -->
易混淆点：软件著作权产生时间（开发完成之日） vs 专利权授权时间（公告日/授权日） vs 商标权取得时间（核准注册日）。注意著作权重“事实创作自动产生”，专利/商标重“行政审查确权”，切勿混淆。 <!-- polish:v1 -->

This change in speed itself becomes a major specification change, and it needs to be proclaimed abroad and weighed from a system point of view. How, then, shall teams （ ） with one another?

A formal project workbook must be started at the beginning.
结合上下文逻辑：“left hand doesn't know what right hand is doing”说明缺乏沟通；后文列举电话、会议、手册均为沟通渠道，故空格处应填communicate；排除法：program/work/talk语义不符或搭配不当，talk偏口语化且不及物用法多，communicate为正式项目沟通标准术语。
⚠ 易混总结
易混淆点：Communicate（双向信息交换与共识建立，项目管理核心） vs Talk（日常交谈，无结构化信息传递含义） vs Inform（单向告知）。在软件工程语境中，强调跨团队协作必须用communicate，体现“约定同步”与“接口对齐”。 <!-- polish:v1 -->
易混淆点：署名权（人身权，绝对不可继承，死后由继承人监督保护） vs 发表权（人身权，但可继承/行使，作者生前未发表的，继承人可在50年内决定是否发表） vs 修改权/复制权（财产权，可继承）。注意考试中常将“发表权”设为陷阱，需明确其特殊继承规则，但本题问“不能继承”，署名权最绝对。 <!-- polish:v1 -->
易混淆点：CA（发证、撤销、验证，信任锚点） vs RA（注册机构，负责身份初审与材料收集，不直接发证） vs CRL（证书撤销列表，是CA发布的清单而非功能本身）。注意RA只受理不决策，CA才拥有撤销与最终验证权限。 <!-- polish:v1 -->

紧扣上下文“slowly change the functions...”与后文“规格说明变更”，空格处应填change；采用排除法：proceed(进行)不接宾语，hide(隐藏)与smooth(使平滑)语义断裂，change精准对应工程变更管理(Change Control)语境。
⚠ 易混总结
易混淆点：Change（泛指开发过程中的功能/参数调整，可能引发配置漂移） vs Modify（通常指代码级修补或文档修订） vs Alter（侧重形式或外观改动）。在项目管理语境中，change强调对基线或约定的偏离，需通过变更流程管控，而modify/alter多指具体执行动作。 <!-- polish:v1 -->

语境推理+词义排除法。抓住“left hand doesn't know right hand”“change assumptions”等提示，判断空缺处需填入表示“高度重要/不可或缺”的褒义词；结合工程管理常识，直接排除表负面价值的worthless/valueless/useless，锁定invaluable。
易混淆点为“合理使用 vs 法定许可 vs 侵权”。合理使用（免许可+免报酬）仅限法条列举；法定许可（免许可+付报酬）如编写教科书汇编已发表作品；公开义演即使公益也受“表演权”控制，不适用合理使用。考题常设“公益/教育”陷阱，需牢记“公益≠合理使用”，必须严格对照法条列举项。 <!-- polish:v1 -->
