Day1-2：时态突破

重点攻克一般现在时、现在进行时和现在完成时。比较'I eat'（习惯）、'I am eating'（进行中）和'I have eaten'（已完成）的用法差异。常见错误：误用现在进行时表达长期状态（如×I am knowing→√I know）。

Day3-4：复合句结构

解析定语从句（who/which/that）和状语从句（when/because/if）。特别注意限制性从句不用逗号分隔（The man who called you is here），非限制性从句需要逗号（Mr. Smith, who called you, is here）。

主动转被动的三步法：1) 宾语变主语 2) 动词变be+过去分词 3) 原主语用by引导。例如：'The dog chased the cat'→'The cat was chased by the dog'。注意不及物动词（如happen）无被动语态。

通过写作纠错练习整合知识点。典型病句分析：'Although it was raining, but we went out'（重复连词错误），正确应为'Although it was raining, we went out'。推荐使用Grammarly工具辅助检测。

She has finished her homework (so now she can relax).

现在完成时强调过去动作对现在的影响

The book which you lent me is fascinating.

定语从句用which指代事物

The proposal was approved by the committee.

被动语态中动作承受者作主语

7天训练聚焦三大语法模块：时态区分强调时间维度，复合句构建复杂表达，被动语态突显动作对象。建议每天投入90分钟，结合例句背诵和即时输出练习。记住：语法是思维的脚手架，熟练后终将内化为语言本能。
