写作五：按五层校验表修订语言

写作能力五：用校验表修订语言

写完后不要只查拼写。修订按“任务—结构—逻辑—句法—词汇”从大到小进行；先修内容和关系，再换词。本课只训练一轮可重复修订。

自拟初稿

Online information are convenient. Students uses it very easy, so every information is helpful. University should teaches them judge sources.

五层修订

任务：主张需要信息评估教育，方向正确。结构：三句可形成现象—风险—建议。逻辑：便利不能推出所有信息有用，应改成转折。句法：information 不可数，主谓一致错误。词汇：use it very easy 改为 access it easily；judge sources 可改 evaluate sources。

修订稿：

Online information is convenient to access, but convenience does not make every claim reliable. Universities should teach students to evaluate sources and evidence.

错解反馈

若只把 convenient 换成 sophisticated，核心逻辑和语法仍错。高级词不能补救任务、因果和主谓问题。

正文练习

修订：The measure have many benefit and it definitely solve the problem.

参考：The measure has several potential benefits, but further evidence is needed to determine whether it can solve the problem.

独立验收

用五层表修订自己的三句段落，每一处修改写明属于哪一层和为什么。
