Amy: That's great! I often collect waste paper to recycle.(太棒了!我经常收集废纸来回收。)
二、核心知识点解析
(一)必掌握单词与短语(附用法)
单词 / 短语 音标 词性 核心用法与例句
protect /prəɒtekt/ 动词 表示 “保护”,搭配
“protect + 名词”(protect
the Earth/animals)例句:
We should protect our
environment.(我们应该
保护我们的环境。)
chemical /ɒkemɒkl/ 名词 意为 “化学药剂”,常用复
数形式 chemicals 例句:
Too many chemicals are
bad for plants.(太多化学
药剂对植物有害。)
soil /sɒɒl/ 名词 表示 “土壤”,不可数名词
例句:Plants grow well in
rich soil.(植物在肥沃的
土壤里长得好。)
turn off /tɒɒn ɒf/ 短语动词 意为 “关闭(电器、水源
等)”,反义词 turn on 例
句:Please turn off the light
when you leave.(离开时
请关灯。)
recycle /ɒriɒɒsaɒkl/ 动词 表示 “回收利用”,搭配
“recycle + 废品”(recycle
paper/bottles)例句:We
can recycle plastic bottles
to make new things.(我们
可以回收塑料瓶制作新物
品。)
(二)重点语法与句型
1. 一般现在时第三人称单数(核心语法)
规则回顾:主语为第三人称单数(he/she/it/ 单数名词)时,动词需变三单形式(加 - s/-es),如
plant→plants,use→uses,say→says。
课文例句解析:
ɒ He plants many trees every year.(主语 he 是三单,plant 加 - s)
ɒ Does he use any chemicals?(疑问句中借助助动词 Does,动词 use 还原为原形)
ɒ He says chemicals are bad for the soil.(主语 he 是三单,say 加 - s)
易错提醒:避免出现 “He plant...”“Does he uses...” 的错误,牢记 “疑问句 / 否定句中助动词用 Does,动
词还原”。
2. 关键交际句型(附场景运用)
句型 1:What are you going to do + 时间状语?
用法:询问对方计划做的事,回答用 “I'm going to + 动词原形”。
场景:周末 / 假期计划讨论,如 “What are you going to do next Sunday? I'm going to clean the park.”(下周
日你打算做什么?我打算去打扫公园。)
句型 2:Does + 主语(三单)+ 动词原形...? Yes, he/she does. / No, he/she doesn't.
用法:询问第三人称单数的日常行为或习惯,是一般现在时的一般疑问句结构。
例句:—Does your dad save electricity at home?(你爸爸在家节约用电吗?)
—Yes, he does. He often turns off the TV when no one watches it.(是的,他节约。没人看电视时他经常关
掉。)
句型 3:主语 + be + bad for...
用法:表示 “某物对某物有害”,反义词组 “be good for...”(对... 有益)。
例句:Smoking is bad for health.(吸烟对健康有害。);Fruits are good for us.(水果对我们有益。)
(三)发音与语调技巧
三单动词发音:“plants” 中 “-s” 在清辅音 /t/ 后读 /s/,“uses” 中 “-es” 读 /ɒz/,“says” 中 “-s” 读 /z/,
注意区分发音规则。
一般疑问句语调:“Does he use any chemicals?” 句尾用升调,表达疑问语气;陈述句 “He says chemicals are
bad for the soil.” 句尾用降调,语气肯定。
短语连读:“turn off” 连读为 /tɒɒn ɒf/,“protect the Earth” 中 “protect” 尾音 /t/ 与 “the” 连读为 /tðə/,
提升口语流畅度。
三、课堂互动与练习设计
(一)角色扮演与实践活动
“环保小达人” 对话模拟:
分组准备 “环保行动卡片”(如 plant trees, save water, recycle paper),每组抽取 2 张卡片;
两人一组用所学句型对话,结合卡片内容拓展:
A: What are you going to do this Saturday?
B: I'm going to recycle paper. What about you?
A: I'm going to plant trees with my friends. Does your mom help protect the Earth?
B: Yes, she does. She often turns off the tap when washing dishes.
要求对话中包含 “be going to” 计划句型和 “Does...?” 疑问句。
“环保建议会” 小组讨论:
围绕 “如何保护校园环境” 展开讨论,每组派代表用英语分享 1-2 条建议,如:
“We should not throw rubbish on the ground. We can plant more flowers in the school garden.”
教师记录建议,整理成 “校园环保公约”,贴在教室墙上。
(二)针对性练习题(附答案与解析)
1. 用所给词的适当形式填空
(1)My father often ______ (save) electricity at home. He ______ (turn) off the lights every night.
(2)—______ your sister ______ (recycle) plastic bottles?(do)
—No, she ______. She ______ (think) it's hard.
(3)Chemicals ______ (be) bad for the soil. We ______ (should) use them.
答案:
(1)saves; turns(主语是三单,动词变三单;every night 提示一般现在时)
(2)Does; recycle; doesn't; thinks(疑问句用 Does,动词还原;否定回答用 doesn't,think 变三单)
(3)are; shouldn't(chemicals 是复数,be 动词用 are;根据句意 “化学药剂有害”,应填 shouldn't “不应
该”)
2. 句型转换
(1)He plants many trees every year.(改为一般疑问句)
(2)I'm going to collect waste paper this weekend.(对划线部分提问,划线:collect waste paper)
(3)Chemicals are bad for the Earth.(改为同义句)
答案:
(1)Does he plant many trees every year?(借助 Does,动词 plant 还原)
(2)What are you going to do this weekend?(对动作提问用 What,保留 be going to 结构)
(3)Chemicals are not good for the Earth.(be bad for 的同义短语是 be not good for)
四、学习与教学建议
(一)学生学习小贴士
场景化记忆:将 “环保行动” 与日常生活绑定,如看到 “关灯” 时默念 “turn off the light”,看到 “废纸”
时联想 “recycle paper”,强化词汇与场景的联系。
语法口诀辅助:记一般现在时三单口诀 “主语三单莫忘记,动词后面 - s/-es 替;疑问句用 Does 提,动
词原形要切记”,避免语法错误。
拓展阅读:阅读简单的英语环保绘本(如《The Lorax》节选),积累更多环保相关表达(如 pollution, clean
energy)。
(二)教师教学建议
跨学科融合:结合科学课 “环境保护” 知识,让学生用英语描述 “植物与土壤的关系”,实现 “英语 + 科
学” 联动。
分层任务设计:
基础层:背诵对话核心句型,完成单词填空;
提升层:仿写 “环保计划” 小短文(如 “My Weekend Environmental Plan”);
拓展层:制作 “环保英语海报”,标注关键短语(如 “Save Water! Turn Off the Tap!”)。
评价激励:设立 “环保英语小标兵” 奖项,鼓励学生在课堂互动、作业中积极运用所学句型,提升语言运
用能力。
