五、重点语法（含中考考点解析）
现在完成时：since & for 的用法 —— 本单元核心语法 & 中考高频考点
1. for 与 since 的区别
表格
用法 搭配 例句
for 后接时间段（表示动作持续多久） I have been a volunteer for three years.
since 后接过去的时间点 / 从句（表示动作从何时开始） I have been a volunteer since 2022. / I have volunteered here since I was 12.
2. 中考高频句型结构
主语 + have/has + 过去分词 + for + 时间段
She has worked as a volunteer for five months.
主语 + have/has + 过去分词 + since + 过去时间点/一般过去时从句
He has been in the team since last August.
I have known her since we were children.
3. 中考易错点
for 和 since 不能互换使用：
错误：I have lived here since three years.
正确：I have lived here for three years. / I have lived here since three years ago.
对 for/since 引导的时间状语提问，要用 How long：
How long have you been a volunteer → For two years. / Since 2020.
六、中考语法考点专项（本单元高频）
1.现在完成时 since/for 的语境辨析中考单选 / 完形高频考点：
区分 for + 时间段 和 since + 时间点。
易错点：since 后接从句时，从句要用一般过去时，主句用现在完成时。
正确：He has lived here since he moved to the city.
错误：He has lived here since he moves to the city.
2.现在完成时的延续性动词（中考高频）
短暂性动词（如 join, leave, begin）不能与 for/since 连用，需转换为延续性动词：
join → be in / be a member of
leave → be away
begin → be on
例句：He has been in the volunteer group for two years.（不用 has joined）
3.used to 的用法（中考常考）
表示 “过去常常做某事（现在不做了）”，后接动词原形：
I used to have a pet dog when I was a child.
易错点：否定形式为 didn’t use to 或 usedn’t to，疑问形式为 Did you use to ...
七、中考补充拓展：单元写作模板
1. 志愿活动 / 帮助他人类作文开头
Volunteering is a great way to help others and make a difference in the world.

2. 描述志愿工作与经历

At the animal shelter, I clean the cages, feed the animals, and walk the dogs. It’s tiring but very rewarding.
During the summer vacation, I joined a beach clean-up activity. We picked up rubbish and cans to protect the environment.
3. 表达意义与收获（中考加分）
Volunteering has taught me the importance of caring for others and working as a team.
It has also helped me develop many practical skills, like communication and problem-solving.
Every small action can make a big difference. Even simple things like giving directions or visiting the elderly can brighten someone’s day.
