一、核心词汇表
环境污染类
环保行动类
描述变化与品质类
二、核心短语归纳
三、语法精讲
语法精讲一：前缀 re-
【语法规则】
前缀 re- 加在动词前，表示「再次；重新；回来」。许多带re-的词与「重复某动作」或「恢复某状态」有关。
【常见词汇】
【易错提醒】
❌ re-cylce ✅ recycle
注意：re-与词根间通常不加连字符。拼写时注意不要漏掉字母。
⚠️ 配套练习
一、用re-加在下列动词前构成新词，并翻译词义：
1. read → ________ (________) 2. write → ________ (________) 3. build → ________ (________)
4. visit → ________ (________) 5. think → ________ (________)
二、单项选择：
1. Scientists fund a way t ________ waste plastic int useful prducts.
A. reuse B. recycle C. return D. rebuild
2. After the earthquake, the city had t ________ many ld buildings.
A. rethink B. reread C. rebuild D. renew
3. The cmmunity has ________ its plan t prtect the river.
A. reused B. recycled C. returned D. renewed
? 参考答案与解析
一、1. reread 重读 2. rewrite 重写 3. rebuild 重建 4. revisit 重访 5. rethink 重新思考
【解析】re-前缀加在动词前表示「再次/重新」做该动作。
1. 答案：B
【解析】考查re-前缀词汇辨析。句意「科学家找到将废塑料______为有用产品的方法」。A选项reuse「重复使用」不合语境；B选项recycle「回收利用」，表示「把……回收制成……」，符合句意；C选项return「返回」不合语境；D选项rebuild「重建」不合语境。故选B。
2. 答案：C
【解析】考查re-前缀词汇辨析。句意「地震后，城市不得不______许多旧建筑」。地震后建筑物被毁需「重建」。rebuild「重建」符合句意。rethink、reread、renew均不符。故选C。
3. 答案：D
【解析】考查renew用法。句意「社区已______了保护河流的计划」。renew意为「更新；重新开始」，renewed plan表示「更新计划」。reuse、recycle、return均不符。故选D。
语法精讲二：现在完成时中 fr 与 since
【语法规则】
现在完成时中，fr 和 since 都表示「从过去延续到现在」，但用法不同：
【句型公式】
S + have/has + 过去分词 + fr + 时间段
【教材例句分析】
【易错提醒】
❌ I have been here since three years.
✅ I have been here fr three years. (three years是时间段→用fr
记忆口诀：fr + 段, since + 点
⚠️ 配套练习
用fr或since填空：
1. She has lived in this city ________ five years.
2. He has been a member f the club ________ last September.
3. They have planted trees here ________ the prject started.
4. We haven't used plastic bags ________ a lng time.
5. The river has been clean ________ tw mnths.
单项选择：
6. — Hw lng have yu been cllecting waste paper?
— ________ I was ten years ld.
A. Fr B. Since C. In D. At
7. He has studied English ________ three years ________ 2021.
A. since; fr B. fr; since C. fr; fr D. since; since
8. The factry ________ prductin since the new plicy ________ .
A. has reduced; came ut B. reduced; has cme ut C. has reduced; has cme ut D. reduced; came ut
? 参考答案与解析
1. fr 【解析】five years是时间段，用fr。
2. since 【解析】last September是过去时间点，用since。
3. since 【解析】the prject started是时间点从句，用since。
4. fr 【解析】a lng time是时间段，用fr。
5. fr 【解析】tw mnths是时间段，用fr。
6. 答案：B
【解析】答句意为「从我十岁起」。I was ten years ld是时间点，用since。A选项fr后接时间段不符；B选项since正确；C/D选项in/at不与现在完成时搭配。故选B。
7. 答案：B
【解析】three years是时间段→用fr；2021是时间点→用since。故选B。
8. 答案：A
【解析】since引导时间状语从句时，主句用现在完成时(has reduced)，从句用一般过去时(came ut)。故选A。

五、易错点归纳与练习
易错点一：fr与since混用
❌ I have studied here since three years.
✅ I have studied here fr three years.
【讲解】three years是「一段时间」，应搭配fr。since后接「时间点」。记忆：fr+段，since+点
练习：1. He has been a vlunteer ________ 2022. 2. She has learned srting ________ tw years. 3. They wrked n the prject ________ it started.
答案：1. since(2022是时间点) 2. fr(tw years是时间段) 3. since(it started是时间点从句)
易错点二：less与fewer混用
❌ Use fewer water.
✅ Use less water. / Use fewer plastic bags.
【讲解】less修饰不可数名词；fewer修饰可数名词复数。记忆：less+不可数，fewer+可数
练习：1. We shuld use ________(little/fewer) paper. 2. We need ________(less/fewer) bttles. 3. The factry prduces ________(less/fewer) waste.
答案：1. less(paper不可数) 2. fewer(bttles可数复数) 3. less(waste不可数)
易错点三：现在完成时与一般过去时混用
❌ I have finished the wrk yesterday.
✅ I finished the wrk yesterday. / I have finished the wrk already.
【讲解】现在完成时不能与具体过去时间连用。有具体过去时间→一般过去时；无具体时间强调影响→现在完成时。
练习：1. She ________(jin) the club since last term. 2. He ________(recycle) paper last Mnday. 3. We ________(plant) trees fr 3 years.
答案：1. has jined(since→现完) 2. recycled(last Mnday→一般过去时) 3. have planted(fr 3 years→现完)
易错点四：中frm后接形式错误
❌ prtect the trees frm cut dwn.
✅ prtect the trees frm being cut dwn. / frm sandstrms.
【讲解】frm是介词，后接名词/代词/动名词(ding)，不接动词原形。
练习：1. prtect animals frm ________(hunt). 2. prtect plants frm ________(wind).
答案：1. being hunted(frm+动名词被动式) 2. the wind(frm+名词)
易错点五：因果表达混淆
❌ （概念混淆，非句子错误）
✅ The main cause f pllutin is factry waste. / As a result, fish died.
【讲解】cause(原因)导致effect/result(结果)。常用：The main cause / As a result, ...
练习：1. The main ________(cause/effect) f air pllutin is factry waste. 2. As a ________(cause/result), many fish died.
答案：1. cause(工厂废水是「原因」) 2. result(As a result「结果」)
