How would you feel? Disappointed/dɪsə'pɔɪntɪd/? Angry? Sad? At this moment you realize people, plants, and animals are all connected /kə'nektɪd/. We need each other to live, and bees are one of the best examples of this connection /kə'nekʃn/. 想象一下，你去所在地区的超市，但几乎没有水果、蔬菜、蜂蜜、牛奶、鸡蛋或巧克力。你会有什么感觉？失望？生气？难过？此时你会意识到人类、植物和动物都是相互关联的。我们彼此需要才能生存，而蜜蜂就是这种联系的最佳例证之一。 常见搭配为 “imagine doing sth.（想象做某事）”“imagine + that 从句”，文中 “Imagine you go to...” 是口语化的祈使句用法，后接宾语从句（省略引导词 that）。 例句：She imagined walking on the moon. 她想象在月球上行走。 后可接名词、代词或 that 从句，文中 “you realize people, plants, and animals are all connected” 后接宾语从句，强调 “突然明白” 的动作。 例句：He finally realized his mistake. 他最终意识到了自己的错误。 由动词 “connect（连接；联系）” 加名词后缀 “-ion” 构成，文中 “this connection” 指代前文 “people, plants, and animals are all connected” 中的 “关联关系”。 搭配：“the connection between A and B（A 和 B 之间的联系）”。 课本语篇过关 30 Bees are very hard-working animals, and their greatest work is pollination /pɒlə'neɪʃn/ . On one trip, they often visit 50 to 100 flowers. As they fly from one flower to another, they take pollen/'pɒlən/ with them. This action /'ækʃn/ helps plants grow. In fact, without /wɪ'ðaʊt/ their work, about 80 per cent /pə'sent/ of the plants in the world cannot grow. For this reason, many scientists believe that bees are the most important animals on this planet /'plænɪt/. 蜜蜂是非常勤劳的动物，它们最重要的工作是授粉。在一次出行中，它们通常会造访 50 到 100 朵花。当它们从一朵花飞到另一朵花时，会携带花粉。这个行为有助于植物生长。事实上，如果没有它们的工作，世界上大约 80% 的植物无法生长。正因如此，许多科学家认为蜜蜂是这个星球上最重要的动物。 后接名词、代词或动名词（doing），文中 “without their work” 表示 “没有它们（蜜蜂）的工作”，引导否定条件，与后文 “cannot grow” 形成逻辑关联（没有蜜蜂工作→植物无法生长）。 例句：We can’t live without water. 没有水我们无法生存。 由并列连词 “and” 连接的并列句，前后两个分句（“Bees are...animals” 和 “their greatest work is...”）为并列关系，分别介绍蜜蜂的 “特质” 和 “核心工作”，结构对称，逻辑清晰。 “as” 为连词，引导时间状语从句，含义为 “当…… 的时候”，强调 “蜜蜂飞行” 和 “携带花粉” 两个动作同时发生，相当于 “when”，但 “as” 更侧重动作的同步性。 课本语篇过关 31 Bees are also one of the most interesting animals in the world. For example, they work hard together to make their homes. In order to store /stɔː(r)/ honey, they create honeycombs /'hʌnikəʊm/. Another interesting thing about bees is how they communicate /kə'mjuːnɪkeɪt/. When a bee finds new food, it uses a dance to tell the others where and how far away the food is. 蜜蜂也是世界上最有趣的动物之一。例如，它们会一起辛勤劳作来筑造自己的家园。为了储存蜂蜜，它们会建造蜂巢。关于蜜蜂，另一件有趣的事是它们的交流方式。当一只蜜蜂发现新的食物时，它会通过跳舞来告诉其他蜜蜂食物的位置以及距离有多远。 “create honeycombs” 指蜜蜂 “建造蜂巢”，强调从无到有构建特定结构的动作，区别于 “make”（泛指 “制作”，侧重过程简单），更体现蜜蜂行为的复杂性。 例句：She created a beautiful painting last week. 她上周创作了一幅漂亮的画。 “communicate with sb.（与某人交流）”“communicate sth. to sb.（把某事传达给某人）”，文中 “how they communicate” 指蜜蜂的 “交流方式”，后文 “use a dance to tell...” 具体解释了这种交流行为。 例句：Dogs communicate with each other through barks. 狗通过叫声相互交流。 结构：“one of + the + 形容词最高级 + 可数名词复数” 含义：“最…… 的…… 之一”，文中用于强调蜜蜂在 “有趣动物” 中的代表性，是初中英语中表达 “范围与程度” 的核心结构，需注意 “形容词最高级前加 the”“后接复数名词” 的规则。 课本语篇过关 32 Bees play an important part in ecosystem /‘iːkəʊsɪstəm/ of our planet. However, the number of bees is dropping, and scientists are worried. Bees need our help, and there is a lot we can do. Think about what you can do to protect /prə’tekt/ one of the most amazing animals on earth. 蜜蜂在我们星球的生态系统中扮演着重要角色。然而，蜜蜂的数量正在不断减少，这让科学家们感到担忧。蜜蜂需要我们的帮助，而我们也能为此做很多事。想一想，你可以做些什么来保护地球上这种极具非凡意义的动物之一。 搭配：“the ecosystem of...（…… 的生态系统）”，文中 “the ecosystem of our planet” 即 “地球生态系统”，是环境科学与生物学的核心概念，体现蜜蜂在全球生态中的定位。 搭配：“the number of + 可数名词复数”，表示 “…… 的数量”，后接谓语动词用单数（因强调 “数量” 这一整体概念），文中 “the number of bees is dropping” 即 “蜜蜂的数量正在减少”，需与 “a number of + 可数名词复数”（表示 “许多……”，后接谓语动词复数）区分。 “part” 可替换为 “role”（“play an important role in” 为同义短语），后接名词或动名词，文中 “play an important part in the ecosystem” 强调蜜蜂对生态系统的关键作用，是表达 “事物重要性” 的高频短语。 当定语从句的关系代词 “that/which” 在从句中作宾语时，可省略，文中完整句子为 “there is a lot (that) we can do” 课本语篇过关 33 3a Read the text and complete the table. The Blue Whale The blue whale is the largest and heaviest animal on earth. It can weigh as much as 200 tons. Many people like watching blue whales swim, and they think it is one of the most beautiful things to see. Blue whales live in all oceans/'əʊʃnz/ except /ɪk'sept/ the Arctic/'ɑːktɪk/ Ocean. They eat a lot, but they eat some of the tiniest /'taɪnɪɪst/ animals in the ocean. A blue whale can eat around four tons of these a day. “as much as 200 tons”（重达 200 吨）、“around four tons”（约 4 吨），用于描述蓝鲸的体重和食量，体现 “列数字” 的说明方法，使描述更具体准确。 注意：“ton” 前接具体数字时，数字大于 1 则用复数 “tons”，如 “5 tons of coal（5 吨煤）”。 用于修饰数量、时间等，文中 “around four tons” 表示 “不确定的近似数量”，是口语和书面语中常用的 “模糊数量表达”，避免绝对化表述。 例句：There are around 50 students in the classroom.（教室里大约有 50 名学生。） 文中多次出现 “the + 形容词最高级” 结构（the largest, the heaviest, the tiniest, the most beautiful），需重点掌握： 核心结构：“the + 最高级 + (名词) + 表示范围的短语 / 从句”（如 “on earth”“in the ocean”）； 特殊变化：“beautiful” 是多音节词（三个及以上音节），最高级需用 “most + 原词”（most beautiful），而非加 “-est”，这是形容词最高级变化的关键规则（单音节 / 部分双音节词加 “-est”，多音节词加 “most”）。 课本语篇过关 34 Blue whales can live up to 90 years. When a blue whale dies at sea, it becomes food for many kinds of animals living in and around the sea. This food lasts for over a year and it helps to create a lively /'laɪvli/ and healthy ecosystem. Blue whales play an important role in our world, so we must protect them. 活到（某一年龄）；达到（期望等） 文中用法：“Blue whales can live up to 90 years.” 表示蓝鲸能活到 90 岁，体现其寿命长度。 在…… 中扮演重要角色；在…… 中起重要作用 文中用法：“Blue whales play an important role in our world...” 强调蓝鲸在世界（生态等方面）的重要性，“role” 可替换为 “part”，即 “play an important part in”。 “When” 引导时间状语从句，表示 “当…… 的时候”，描述 “蓝鲸在海中死亡” 这一动作发生时，“成为其他动物食物” 这一结果出现，体现动作的时间关联。 “living in and around the sea” 是现在分词短语，作后置定语，修饰 “animals”，相当于定语从句 “many kinds of animals which/that live in and around the sea”，表示 “生活在海里及周边的多种动物”，现在分词作定语常用来表示主动或进行的动作。 这部分采用 “分 — 总” 逻辑，围绕 “蓝鲸的生命历程及生态作用” 展开： 先介绍蓝鲸的寿命（能活到 90 岁）； 接着描述蓝鲸死后在海中成为其他动物的食物，且这种食物能持续一年以上，有助于创造良好生态系统； 最后总结蓝鲸的重要性，得出必须保护它们的结论，逻辑清晰，从蓝鲸个体生命延伸到对整个生态的影响。 课本语篇过关 35 05 重点句子过关 36 １. When a bee finds new food, it uses a dance to tell the others where and how far away the food is. 当一只蜜蜂发现新的食物时，它会用舞蹈来告诉其他蜜蜂食物在哪里以及有多远。 重点句子过关 ① 本句含有 when 引导的时间状语从句，遵循 “主将从现”，此处主句从句都用一般现在时，描述客观事实；主句包含 where 引导的宾语从句，宾语从句必须使用陈述语序。 ② use sth. to do sth. 使用某物做某事，to do 不定式表目的。 ③ the others 其余的（人 / 物），特指一个范围内剩下的全部；区分 others（其他一些，泛指）、other + 名词复数。 ④ how far away 多远，用来询问距离；far away 遥远的，far away from… 离…… 很远。 ⑤ 例句：When my cat finds fish, it uses sound to tell the other cats where the food is. 当我的小猫找到鱼时，它会发出声音告诉别的小猫食物在哪里。 37 重点句子过关 2. The blue whale is the largest and heaviest animal on earth. 蓝鲸是地球上体型最大、体重最重的动物。 ① 本句是主系表结构；the largest、heaviest 是形容词最高级，形容词最高级前面一般要加 the。 ② 并列最高级用 and 连接：the + 形容词最高级 and + 形容词最高级。 ③ on earth 在地球上；另外 on earth 还可用于疑问词后，表示 “究竟、到底”。 ④ 例句：The elephant is the biggest and strongest animal on land. 大象是陆地上体型最大、最强壮的动物。 38 3.
