摘要:
该初中英语课件围绕“Greener Planet, Better Home”主题,以石光银治沙故事为载体,涵盖核心词汇(spreading, survive等)、文本结构(Introduction-Body-Conclusion)及概括、因果链阅读策略。课堂导入通过“环境侦探局”图片对比和三台阶预测支架,连接Pre-reading预测与While-reading文本验证,构建知识脉络。
其亮点在于聚焦思维品质与语言能力培养,通过因果链分析(如树存活→土地变绿的链式反应)和概括策略(从具体人物到保护环境的普遍道理)提升逻辑思维,结合思维导图复述和分层作业设计,强化环保文化意识。学生能提升分析与表达能力,教师可获得结构化教学流程与多样化活动支持。

Para 1 逐句分析
原文展示
In northwest China's Shaanxi Province,
a farmer has fought against desert growth
for more than 40 years.
词汇 / 短语解析
has fought (现在完成时)

fight against (对抗)
固定搭配,意为“与……作斗争;对抗”。
more than 40 years (时长之久)

国家政策
沙漠的扩张
(环境问题)
国家政策带来的
chance(机会)
石光银果断抓住机会,
付诸行动
讲解语:
这是一个典型的长难句。主语是动名词短语。当别人都在面对问题时,石光银看到了什么?
他看到了国家政策带来的chance(机会),并果断抓住了。但抓住了机会,就一定能成功吗?
While-reading
第一次尝试与失败

他没有蛮干,而是去寻求专家建议,去学习世界的经验。
这正是“思考”的力量。
他学会了方法之后,是如何将理论化为实践的?

☺ 没有规划,盲目种树

第三组是方法带来的结果,第四组是努力带来的结果。
因果关系贯穿整个故事,同时也让我们看到了治沙的成效!
接下来通过Activity 5巩固词汇。
Shi has made great efforts
to control desert growth
Activity 5
Vocabulary in Depth
Explanation
Choose the correct words from the box and complete the sentences.
Activity 5 要求我们根据语境选词填空,这不仅仅
是选词,更是在考验我们对词性和固定搭配的理解。
spreading
survive
control
protect…from
先看第一句:“第一年大多数树苗没能在沙尘暴中
。”沙尘暴是宾语,树苗在恶劣环境中活了
下来,所以填 survive。注意,本句中 survive 作及物动词,直接接宾语 the sandstorms,不加介词 in。
1. Most young trees didn't the sandstorms…
接着看第二句:“石光银带领人们设置屏障来
沙尘暴。”设屏障的目的是防止树
苗受到伤害,考查固定短语 protect…from…(保护
……免受……的伤害),所以两个空分别填 protect
树苗
和 from。
2 Shi led people to set up blocks to the trees sandstorms.
再看第三句:“石光银成立公司来成立公司来 沙土
成立公司是为了治理沙土,不让它扩张,所以填
control(控制)。 control 在这里作动词。
3. Shi founded a company to the sand…
最后看第四句:“许多村民加入公司来对抗沙漠的 。”
前面有 the 和 of,说明需要填名词,表
示沙漠的“扩散、蔓延”,所以填 spreading。
4. Many villagers joined… fight against the of the desert.
这四个词完美对应了石光银治沙故事的四个阶段:
生存挣扎,主动控制,防御保护,共同对抗蔓延。
理解了这些词的语境差异,我们就掌握了这节课
的核心词汇。

Strategy:
Making Generalizations
找具体例子
从文章中找出具体的事例或细节。
提炼共同点
分析这些例子的共同点或相似之处。
得出结论
根据共同点,归纳出一个一般性的结论或道理。
讲解语
概括不仅仅是总结,
更是思维的提升。我们
从石光银的故事中,概括
出了“全体人类需要保护
环境”的真理。
那另一种阅读策略
因果分析如何应用?
Strategy:
Cause and Effect
Good readers find cause-and-effect
relationships to understand the logic
of a passage.
Signal Words to Look For
Because, So, Therefore,
As a result…

The sky was cloudy in the morning.
He studied very hard for the test.
So, he got the highest score in the class.
They were excited about the trip.
Therefore, many passengers missed their
connecting flights.
He likes to play basketball.
He studied very hard for the test.
Because it was cloudy, we brought umbrellas.
We went to the park after lunch.
Why It Matters
Understanding cause and effect helps you
see why things happen in the story.
Look for the signal words—they will
guide you!
掌握因果关系,就是掌握文章的逻辑命脉。
找信号词,事半功倍。
故事讲完,策略学完,我们就要挑战输出了。
The train was delayed by the storm.
She forgot to set the alarm last night.
As a result, she woke up late this morning.
She had breakfast quickly.

04 Post-reading
讲解语:“现在我们进入Post-reading,请大家根据黑板上的流程图,按‘开端→发展→高潮→结局’的顺序复述石光银40年的治沙故事。
同桌之间先互相练习,注意使用我们刚刚学过的词汇,比如“took the chance’,‘set up blocks’,‘protect…from’等。稍后我会请同学上台汇报。
复述完故事后,我们就要进入本课最关键的语言点讲解环节(Language Points),看看课文里有哪些重点词汇和短语需要我们特别掌握。”

Language Points
Language Points (语言点 1)
词
take the chance /teɪk ðə tʃɑ:ns/ 抓住机会
take the chance 意为“抓住机会”,后可接 to do sth.(抓住机会做某事)。
详解
近义词组为 seize the opportunity。
易错点:本课固定搭配 take the chance 中,chance 前用 the;注意区分 take a chance(冒险一试)。
例
Shi Guangyin took the chance in 1984 to plant trees.
我们必须抓住这次机会改善环境。
We must
to improve the environment.
练
如果你不抓住机会,你就会失去它。
If you don't
, you will lose it.
讲解语:第一个知识点是 take the chance。它强调“果断抓住转瞬即逝的机遇”。注意,后面要接不定式“to do”。
现在请完成两道原创练习,第一题填 take the chance,第二题填 take the chance。
掌握这个短语后,我们看下一个知识点。
Language Points •
词
set up
建立;设立;设置
详解: set up 意为“建立、设立”,强调从无到有的过程,常接
organization (组织), equipment (设备), blocks (屏障) 等。
易混辨析: set up 侧重 “搭建/安装”;found 侧重 “正式创建(公司/机构)”。
例
He founded a company to set up blocks to protect the trees.
练
他们去年在这座城市建立了一个新的环保组织。
They
a new environmental group in this city last year.
我们在森林里设置了屏障来挡住风沙。
blocks in the forest to stop the sand.
We
讲解语:“第二个知识点是 set up。注意它与 found 的区别:set up 是配置、搭建,
found 是正式创立。课文中是 “set up blocks”(设置屏障)。请完成练习,
第一题填 set up,第二题填 set up。接下来看第三个,也是最重要的一个。”
Language Points
题目词
protect…from… /prə'tekt frɒm/
保护…免受…
protect…from… 意为“保护…免受…的伤害”,from 后面通常跟名词
或动名词(v-ing),指代具体的伤害源。
近义词组: defend…against, keep…safe from。
例
Shi led people to set up blocks to protect the trees from sandstorms.
练
我们应该保护环境免受污染。
We should
the environment
pollution.
戴上太阳镜可以保护你的眼睛免受阳光伤害。
Wearing sunglasses can your eyes the sun.
讲解语:第三个知识点是 protect…from…。请特别注意,from 后面要接伤害源,
不能接保护对象。这道题的答案分别是 protect…from 和 protect…from。
这三个核心短语学完,我们来总结这节课的核心内容。
