It has a(n) “measurement, e.g.,area/length/height” of + 数字 + “unit, e.g., square kilometres/metres”. 句型解析：该句型用于先明确自然奇观的地理位置，再具体说明其面积、长度、高度等尺寸，语气正式，适合书面表达（如作文、句型仿写）。 - is located + 地点：“位于……”，located是过去分词，可替换为situated（用法完全一致，更书面化）；地点可具体到国家、地区、方位（如in the south of China）。 - has a(n) + 度量名词（area面积/length长度/height高度/depth深度）+ of + 数字 + 单位：“有……的（尺寸）”，数字可结合实际情况使用约数（about/around）或精确数。 例句拓展： The Great Barrier Reef is located off the coast of Australia. It has an area of about 2,900,000 square kilometres. Mount Tai is located in Shandong Province, China. It has a height of about 1,545 metres. 易错点：单位的单复数变化——数字大于1时，单位用复数（如2 kilometres）；数字为1时，用单数（1 kilometre）；平方单位需加square（如square metres，不可缩写为m²，书面表达需写完整）。 35 重点句型 句式要点 1. “Natural wonder” is located + 地点. It has a(n) “measurement, e.g.,area/length/height] of + 数字 + “unit, e.g., square kilometres/metres”. 变式句型：[Natural wonder] is + 数字 + [unit] + [measurement term, e.g., long/deep/high]. 句型解析：该变式更简洁，直接用“主语 + be动词 + 数字 + 单位 + 度量形容词”描述尺寸，口语和书面语均可使用，适合简洁表达。 - 度量形容词（long长的/deep深的/high高的/wide宽的）需放在单位后面，不可颠倒顺序（错误：6,300 long kilometres；正确：6,300 kilometres long）。 例句拓展： The Yellow River is about 5,464 kilometres long. Lake Baikal is about 1,637 metres deep. The Grand Canyon is about 1.6 kilometres deep and 29 kilometres wide. 拓展用法：可在数字前加about（大约）、nearly（将近）、over（超过）等词，使表达更灵活（如The Amazon River is over 6,400 kilometres long.）。 36 重点句型 句式要点 2. “Natural wonder” is the + 最高级（e.g., highest/deepest/largest）+ “category, e.g., mountain/lake/desert”+ in the world/China/Africa. 句型解析：用于表达“某自然奇观是世界/中国/非洲等范围内最……的（类别）”，突出其独特性，是书面表达中增强说服力的常用句型。 - 最高级变化规则：① 单音节词（high→highest, deep→deepest）直接加-est；② 多音节词（large→largest, beautiful→most beautiful）加most；③ 不规则变化（good→best, bad→worst，本主题暂不涉及）。 - 范围限定（in the world/in China/in Asia）不可省略，否则语义不完整（错误：Mount Qomolangma is the highest mountain.；正确：Mount Qomolangma is the highest mountain in the world.）。 例句拓展： The Sahara Desert is the largest desert in the world. Lake Baikal is the deepest lake in the world. The Three Gorges Dam is the largest water control project in China. 易错点：最高级前必须加定冠词the，不可遗漏（错误：Mount Qomolangma is highest mountain in the world.）。 37 重点句型 句式要点 2. “Natural wonder” is the + 最高级（e.g., highest/deepest/largest）+ “category, e.g., mountain/lake/desert” + in the world/China/Africa. 变式句型：[Wonder A] is + 比较级（e.g., longer/deeper）+ than [Wonder B]. 句型解析：用于两者之间的对比，说明“奇观A比奇观B更……”，比较级后必须加than，than后可接名词、代词或从句（本主题中多接名词）。 - 比较级变化规则：① 单音节词（long→longer, deep→deeper）加-er；② 多音节词（large→larger, important→more important）加more；③ 不规则变化（many→more, much→more，本主题暂不涉及）。 例句拓展： The Amazon River is longer than the Yangtze River. The Mariana Trench is deeper than any other trench in the ocean. The Grand Canyon is wider than the Yarlung Zangbo Grand Canyon. 拓展用法：可在比较级前加much（……得多）、a little（稍微……）、even（甚至更……）等词，加强对比语气（如The Mariana Trench is much deeper than the Dead Sea.）。 38 重点句型 句式要点 3. How + 维度词（e.g.,high/deep/long/large）+ is “natural wonder”? 句型解析：用于对自然奇观的高度、深度、长度、大小等维度进行提问，是特殊疑问句，回答时需直接给出具体数值+单位+维度词（或省略维度词，仅用数值+单位）。 - 维度词对应：high（高度）、deep（深度）、long（长度）、wide（宽度）、large（大小，侧重面积）； - 回答句式：It’s + 数字 + 单位 + （维度词）.（维度词可省略，如It’s 8,848.86 metres. 等同于It’s 8,848.86 metres high.） 例句拓展（问答配对）： — How long is the Yangtze River? — It’s about 6,300 kilometres (long). — How deep is Lake Baikal? — It’s about 1,637 metres (deep). — How high is Mount Tai? — It’s about 1,545 metres (high). 易错点：提问时维度词不可遗漏，且句式为“疑问词+一般疑问句”（错误：How is Mount Qomolangma high?；正确：How high is Mount Qomolangma?）。 39 重点句型 句式要点 3. How + 维度词（e.g., high/deep/long/large）+ is “natural wonder”? 变式句型：How + 维度词 + is the [measurement, e.g., area/length] of [natural wonder]? 句型解析：该变式更正式，侧重询问“自然奇观的某一维度（面积、长度等）是多少”，回答时需对应维度，用“ It’s + 数字 + 单位 + （维度词）.” 或 “The [measurement] of it is + 数字 + 单位.”。 - 结构拆解：the [measurement] of [natural wonder] 表示“某自然奇观的……（维度）”，of所有格不可替换为’s（错误：the Sahara Desert’s area；正确：the area of the Sahara Desert）。 例句拓展（问答配对）： — How large is the area of the Sahara Desert? — It’s about 9,000,000 square kilometres. — How long is the length of the Yellow River? — The length of it is about 5,464 kilometres. — How deep is the depth of the Mariana Trench? — It’s about 11,000 metres deep. 拓展用法：可替换为“What’s the [measurement] of [natural wonder]?”（更简洁），如What’s the area of the Great Barrier Reef? 40 重点句型 句式要点 4. “Natural wonder” helps + 受益对象（e.g., ancient civilizations/animals/people）+ 动词原形（e.g., develop/survive/learn about nature）. 句型解析：用于说明自然奇观对某一受益对象的帮助，“help + 宾语 + 动词原形”是固定搭配，意为“帮助……做某事”，语气简洁，口语和书面语均可使用。 - 受益对象：可为人（people/children）、群体（ancient civilizations/local people）、动物（underwater animals/wild animals）等； - 动词原形：需用及物动词或不及物动词短语（develop发展、survive生存、learn about nature了解自然、protect the environment保护环境）。 例句拓展： The Yangtze River helps Chinese people get water and electricity. The Great Barrier Reef helps many fish and coral survive. Mount Huang helps people learn about traditional Chinese culture and natural beauty. 拓展用法：help后的动词原形可省略to（也可加to，即help sb. to do sth.），两种用法均正确（如The Yellow River helped ancient Chinese civilizations (to) develop.）。 41 重点句型 句式要点 4. “Natural wonder” helps + 受益对象（e.g., ancient civilizations/animals/people）+ 动词原形（e.g., develop/survive/learn about nature）. 变式句型：[Natural wonder] is important because + 原因（e.g., it provides homes for animals/teaches us about nature）. 句型解析：用于说明自然奇观重要的具体原因，because引导原因状语从句，从句需用完整的句子结构（主语+谓语+宾语），语气更具体、有说服力，适合书面表达。 原因表达：provide homes for...（为……提供栖息地）、teach sb. about...（教某人关于……）、keep the ecological balance（维持生态平衡）、be a symbol of...（…的象征）。 例句拓展： Lake Baikal is important because it provides homes for over 1,200 types of animals and plants. The Sahara Desert is important because it teaches us about the power of nature and climate change. 易错点：because后接完整句子，不可只接名词或短语（错误：Lake Baikal is important because over 1,200 types of animals.；正确：Lake Baikal is important because it has over 1,200 types of animals.）。 42 课本句子梳理 句式要点 5. “Human group, e.g., Chinese team/explore”+ 动作（e.g., climbed/dived/researched）+ “natural wonder”+ 时间 + to + 目的（e.g., measure its height/record animals）. 句型解析：用于描述人类（团队、探险家等）对自然奇观的探索行为，包含“探索者+动作+探索对象+时间+探索目的”，结构完整，适合描述历史事件或现代探索成就，书面表达常用。 动作动词：需用过去式（climbed/dived/researched/explored），因为探索行为多发生在过去； - 时间：可具体到年份（in 1960）、月份（in July 2020），放在动作后、目的前； - to + 目的：不定式短语作目的状语，说明探索的目的，to后接动词原形。 例句拓展： A Chinese team explored the Yarlung Zangbo Grand Canyon in 1998 to learn about its geography. Explorers dived into the Mariana Trench in 2012 to measure its exact depth. Scientists have researched Lake Baikal for many years to study its unique ecosystem.（此处用现在完成时，强调探索持续到现在） A group of students visited Mount Tai last year to learn about its natural and cultural value. 43 课本句子梳理 句式要点 5. “Human group, e.g., Chinese team/explorer” + 动作（e.g., climbed/dived/researched）+ “natural wonder” + 时间 + to + 目的（e.g., measure its height/record animals）. 拓展用法： 1. 目的状语可替换为in order to + 动词原形（语气更正式），如A Chinese team climbed Mount Qomolangma in 1960 in order to place the national flag there.；2. 探索者可具体到人名（e.g., Xu Xiake），如Xu Xiake traveled around China in the Ming Dynasty to record natural wonders. 易错点：动作动词需用正确的过去式（错误：A Chinese team climb Mount Qomolangma in 1960.；正确：A Chinese team climbed Mount Qomolangma in 1960.）；不定式to不可省略。 44 重点句型过关 1．books  read  ten thousand  miles  travel  ten thousand _____________________________________________. 2．he, good, wonder, at, if, I, English, is (连词成句) _______________________________________________. 3．we, should, do, what, help, to, protect, it (?) ________________________________________ 4．many, there, are, in, the, animals, rainforest, endangered (.) ________________________________________. 5．is, important, it, protect, to, nature (.) ________________________________________ Read ten thousand books; travel ten thousand miles I wonder if he is good at English.
