In 1962, Wang Shanghai moved with his family from their house in Chengde to the ________ lands of Saihanba. There were few trees to hold the ______ together, and there were often ________________. Temperatures were below freezing during the winter. Life there was very difficult. 2c Complete the passage with the correct forms of the words in the box. government bush sandstorm result sandy soil sandy soil sandstorms With support from the ____________, Wang Shanghai led a group of 369 people who were determined to make the environment of Saihanba better. Over the next 60 years, workers planted ________ and trees, creating the world’s biggest man-made forest. Today, Saihanba is known as “the green miracle”. This is the ________ of hard work and people working together. Now, the land is covered with green trees and the water is clean and fresh. government bushes result What was Saihanba like in 1962? What is Saihanba like now? What did people do to change it? Why is it called “the green miracle”? Discuss the questions and share your ideas. It was sandy. There were sandstorms. The soil couldn't be held together. It is covered with green trees. The water is clean. It's a 'green miracle'. They planted bushes and trees with the government's support. Because it was impossible to imagine, but they made it happen through hard work. 5. What can we learn from the Saihanba story? Hard work can make a difference. Teamwork and government support are important. Never give up—even a sandy wasteland can become a green forest. We can all help protect the environment. 1. Why did Wang Shanghai and his friends plant trees in Saihanba? To protect the soil and stop the sandstorms and finally to improve the environment in Saihanba. They are selfless, determined, and tough. 2. What do you think of them? What other stories do you know about China’s environmental achievements? In the 1990s, people in Yucun Village (Zhejiang) dug stone from mountains. As a result, sandstorms covered homes, farmland became dirty, and the river lost all fish. People had money but lived with dust and coughs. With the government’s help, Yucun closed the stone sites in 2003. Villagers planted bushes and trees to fix the soil, and cleaned the river. Today, Yucun’s hills are green—hikers visit, fish swim in the river, and locals sell tea from new farmland. This result proves: caring for nature makes life better. Language points Point 1 Compound words 一、定义 由两个或多个独立单词拼合，组成一个新单词，词义结合两个单词含义，这类词叫复合词。它的含义通常和组成部分的意思相关，但不是简单相加，而是产生了一个整体的、新的概念。 例：butter（黄油）+ fly（苍蝇）= butterfly 蝴蝶 二、书写形式 1.连写式：两个单词直接连在一起，无空格和连字符，也是课本中最常出现的类型，例如 full-butterfly 蝴蝶blackboard、classroom、homework。 连字符式：单词之间用短横线连接，多出现于形容词、数词类复合词， 2. 中间加连字符： man-made full-time、good-looking、eight-year-old。 3.分写式：两个单词分开书写，形式接近短语，但整体表达单一含义，如 post office、bus stop。 三、复合名词构成规律 1.名词 + 名词 = 复合名词 这是初中最核心的复合词类型，两个名词组合后依然作名词，用来表示事物、场所、身份等。 例： sun（太阳）+flower（花）构成 sunflower 向日葵；book（书）+shop（商店）构成 bookshop 书店；police（警察）+man（人）构成 policeman 男警察。 2.形容词 + 名词 = 复合名词 组合后多为名词，用前面的形容词限定后面的名词，描述具备对应特征的人或事物。 例： black（黑色的）+board（木板）构成 blackboard 黑板；green（绿色的）+house（房子）构成 greenhouse 温室。 3.介词 / 副词 + 名词 = 复合名词 这类词汇大多作名词，常用来指代职业、物品或活动。 例：sight（景象）+seeing（看）构成 sightseeing 观光；house（房子）+keeping（打理）构成 housekeeping 家务管理。 4. 副词 / 介词 + 名词 / 动词 数量相对较少，整体多为名词或动词。 例：out（向外）+side（边）构成 outside 外部；over（越过）+come（来）构成 overcome 克服。 5. 名词 / 形容词 + 过去分词 / 形容词 多用作形容词，常带连字符，在写作和阅读理解中高频出现。 例： world（世界）+famous（著名的）构成 world-famous 世界闻名的；warm（温暖的）+hearted（心地）构成 warm-hearted 热心的。 四、核心考点与注意事项 1. 词义推断：遇到不认识的复合词，可以通过拆分组成部分来猜测含义。比如看到 “farmland”，知道 “farm” 和 “land” 的意思，就能推断出它和农田相关。但也要注意特殊情况，比如 “greenhouse” 就不能直接按字面意思理解。 2. 单复数变化：复合词的复数形式通常是在整个单词的末尾加 “-s”，而不是在组成部分后面加。比如 “classroom” 的复数是 “classrooms”，不是 “classesroom”。 3. 词性与用法：大部分复合词是名词，用法和普通名词一样，比如可以作主语、宾语等。少数复合词是形容词或副词，比如 “world-famous（世界闻名的）” 是形容词，“anywhere（任何地方）” 是副词，要注意区分词性，避免用错语境。 Point 2 本句中的核心句型为“make it + 形容词 + for sb + to do sth”。it（形式宾语）代替后面的真正宾语（不定式短语 “to travel across the river to the city”），避免句子结构头重脚轻。 例句： The app makes it easy for students to learn English. 这款应用程序让学生学英语变容易了。 The bridge made it convenient for the villagers to travel across the river to the city.这座桥让村民们过河去城里变得很方便。 Point 3 ... Wang Shanghai led a group of 369 people who were determined to make the environment of Saihanba better. 王尚海带领了一支由369人组成的队伍，他们决心让塞罕坝的环境变得更好。 lead /liːd/ v. 带领；过（某种生活）n. 领先地位；主角 过去式、过去分词：led 带领 过（某种生活） She leads a team of 20 software engineers. 她带领着一个20人的软件工程师团队。 He leads a happy life in the country. 他在乡下过着幸福的生活。 lead 动词 领先 We lead the way in space technology. 我们在航天技术方面处于领先地位。 领先地位 主角 She took the lead on the second lap. 她在第二圈时领先。 lead 名词 She plays the lead in her school play. 她担任学校戏剧中的主角。 take the lead 领先 作动词的其他含义： (1) 导致（后果） lead to 导致 Lack of sleep can lead to tiredness during the day. 睡眠不足会导致白天疲惫。 (2) 通往；通向 The path led down to a small lake. 这条路通向一个小湖。 词义拓展 22 Point 3 3. ...Wang Shanghai led a group of 369 people who were determined to make the environment of Saihanba better. ……王尚海带领一支由369人组成的团队，他们决心要改善 赛罕坝的环境。 （1）be determined to do sth意为“决心做某事”，强调坚定的意愿，比want to do语气更强。 （2）determination是determined的名词形式。 例句： He is determined to learn English well. 他决心学好英语。 Point 4 The road used to be narrow and dirty. 道路过去常常又窄又脏。 narrow /ˈnærəʊ/ adj. 狭窄的 It’s quite narrow—you can easily step across. 它很窄，你可以很容易地跨过去。（作表语） They were climbing up a narrow mountain road. 他们正沿着一条狭窄的山路向上爬。（作定语） 反义词：wide 宽阔的 [形容词] 狭隘的；目光短浅的 She has a very narrow view of the world. 她对世界的认识是非常狭隘的。 词义拓展 Exercises 一、用括号内所给单词的适当形式填空。 1.
