情景导入
六月的教室里，黑板上写着两行字：Save the earth. / Remember our three years. 班主任让每人说一句话，同学们的表达出奇地一致。小林说：Plastic bags should not be used any more.（塑料袋不该再用了。）小周说：I remember planting a tree with you in Grade Seven.（我记得七年级时和你们一起种树。）你说：I used to be shy, but now I dare to speak in front of everyone.（我以前很害羞，现在敢在大家面前讲话了。）
三句话恰好覆盖本专题三大语言点：被动语态提建议、remember doing 回忆过去、used to do 对比变化。学会它们，环保与毕业两类作文都能从容应对。
核心词汇
环保与毕业话题核心词汇：
| 单词/短语 | 意思 | 例句 |
|---|---|---|
| environment | n. 环境 | We should protect the environment. |
| pollution / pollute | n. 污染 / v. 污染 | Air pollution is a serious problem. |
| recycle | v. 回收利用 | Waste paper can be recycled. |
| throw away | 扔掉 | Don't throw away used batteries. |
| make a difference | 起作用，有影响 | One small action can make a difference. |
| graduate | v. 毕业 | We will graduate from junior high school. |
| look forward to doing | 期待做某事 | I'm looking forward to starting high school. |
句型与语法
① 用被动语态提环保建议： ——Water should be saved. / Rubbish must be sorted before it is thrown away. / Plastic bags shouldn't be used any more.
② remember / forget 后的两种形式（考试爱考）
| 结构 | 含义 | 例句 |
|---|---|---|
| remember doing | 记得做过（已发生） | I remember visiting the museum. |
| remember to do | 记得要去做（还没做） | Remember to turn off the lights. |
| forget doing | 忘记做过 | I'll never forget meeting you. |
| forget to do | 忘记要做 | Don't forget to bring your notes. |
③ used to do：过去常常（现在不再）——I used to be afraid of English, but now I love it. 否定与疑问：I didn't use to like maths. / Did you use to play the piano?
④ 毕业作文高频句式：Three years have passed, and I have learned a lot.（现在完成时）/ I would like to thank my teachers for helping me.（感谢）/ I'm looking forward to studying in a new school.（to 后接动名词）
听说训练
两组话题对话（同桌配合，一环保一毕业）：
- A: What should be done to protect our city? — B: Rubbish should be sorted, and shared bikes should be used more often. / A: What do you remember most about these three years? — B: I remember running the 800 metres on sports day. I used to give up easily, but that day I finished it.
跟读要点：should be 连读成 /ʃʊdbi/；used to 中的 d 与 t 合并，读作 /juːstə/，别读成 /juːzd tuː/。
辨析对比
① used to do / be used to doing / be used to do
| 结构 | 含义 | 例句 |
|---|---|---|
| used to do | 过去常常 | I used to walk to school. |
| be used to doing | 习惯于做 | I am used to getting up at six. |
| be used to do | 被用来做（被动） | Bamboo is used to make chairs. |
② 环保三兄弟 reduce / reuse / recycle：reduce（减少使用）、reuse（重复使用）、recycle（回收再造）——We should reduce waste, reuse old things and recycle paper.
③ thanks to vs thanks for：thanks to + 人/事物，意为"多亏"（Thanks to my parents, I never gave up.）；thanks for + doing，意为"因……而感谢"（Thanks for helping me.）。
文化角
在英语国家，环保口号常用被动语态和押韵的三词短句：Reduce, Reuse, Recycle。而杭州人早已把环保过成了日常：垃圾分成"可回收物、有害垃圾、厨余垃圾、其他垃圾"四类，西湖边的公共自行车和地铁串成绿色出行网，钱塘江边的护鸟志愿者每年记录江豚与候鸟的踪迹。毕业季则有另一种仪式感：英语国家的学生在毕业年鉴（yearbook）上互写留言，最常见的一句是 Never say goodbye, say see you later. 试着把它写进你的同学录。
易错点
- should 后漏 be：Trees should planted every spring. ❌ → should be planted ✅
- remember 两种形式混用：Remember closing the window before you leave. ❌ → Remember to close ✅（还没做）
- used to 后加 doing：I used to playing football. ❌ → used to play ✅
- look forward to 后加原形：I'm looking forward to see you. ❌ → to seeing you ✅（to 是介词）；Thanks to helping me. ❌ → Thanks for helping me. ✅
中考真题
— Our school will hold a graduation ceremony next week.
— Wonderful! I hear that the hall ______ with flowers, and every student ______ to give a short speech.
A. will be decorated; is asked B. will decorate; asks C. is decorated; will ask D. decorates; is asked
✏️ 点击查看解答
答案：A
解析：第一空主语 the hall（礼堂）是被装饰的，且时间为 next week，用一般将来时的被动 will be decorated，排除 B、D 的主动形式；第二空 every student 是被要求发言，用一般现在时被动 is asked（表示现在的安排规定）；C 项第一空时态错、第二空 will ask 是主动。口诀依旧是：主语被动看语态，时间状语定时态。
考点
- 环保是中考阅读与书面表达的第一大话题，被动语态提建议（should be done）是得分句型；
- remember / forget + doing 与 + to do 的区别，几乎每年出现在单选或语法填空中；
- used to do、be used to doing、be used to do 三者辨析属于易错高频题；毕业类作文黄金框架：回顾（I remember... / I used to...）→ 感谢（Thanks to / thank sb. for）→ 展望（look forward to doing）。
诵读 Read Aloud
Three years have passed, and it is time to say goodbye to my junior high school. When I look back, I find that I have changed together with my city.
I still remember joining the Green Club in Grade Seven. We planted young trees along the river and told people that plastic bags should not be used any more. At home, rubbish is now sorted into four kinds, and old books are collected and recycled instead of being thrown away. I used to think that one student could do nothing, but I have learned that small actions make a difference.
The three years have also changed me. I used to be too shy to answer questions, and my English was the weakest subject in my report. Thanks to my teachers, who never laughed at my mistakes, I slowly found my voice.
Now I am looking forward to studying in a senior high school. I will keep the two habits that these years have given me: protecting the earth that feeds us, and thanking the people who help us grow.
诵读小贴士：短文把两个单元合成一篇——第二段是环保素材（被动语态密集），第三、四段是毕业素材（used to / thanks to / look forward to）。背下它，考场上遇到"环保行动"或"初中回顾"任一题目都能直接改写。
