UNIT 2 2 教材原文助读4-（配套课件）【学霸笔记·同步精讲 教材助读 语基默写】2024-2025学年高中英语选择性必修第四册（人教版）

该高中英语课件围绕“澳大利亚特有的生物”主题，系统梳理袋鼠、考拉等动物相关词汇（如unique to, symbol）、语法结构（with复合结构、定语从句）及文化内涵，通过专家问答形式导入，搭建从词汇积累到语篇理解的学习支架，帮助学生衔接语言知识与文本分析。 其亮点在于融合语言能力与文化意识培养，通过熟词生义（如resolve表“决心”）、语法注释（如“the dead”表一类人）提升语言理解，结合澳大利亚动物象征意义（袋鼠体现民族精神）增强跨文化认知。采用词汇-语法-语篇递进教学，学生能夯实语言基础并深化文化理解，教师可直接利用系统资源提升教学效率。

It has to be the kangaroo, as it has a wide distribution③ throughout the country. It's a tough④ animal that has to survive in a difficult environment. Also, it cannot walk backwards, so it is always moving forwards. This expresses the strength and resolve⑤ of the Australians as individuals⑥ and as a nation. Baby kangaroos weigh only two grammes at birth⑦. They then find their way into their [第一部分　教材助读] mother's pouch⑧ —a kind of pocket—to stay safe and warm. They sleep and drink milk in that temporary⑨， protected environment [2]until they are about seven or eight months old. After this phase⑩， they go out to try their legs. After they learn to jump, they gradually spend less time with their mother and learn to be independent. [3]Kangaroos may look cute, but encounters with⑪ them don't always end so well. Kangaroos can hit and kick very hard, so please folks, if you see some kangaroos, remember they're not for petting! [2]此处为until引导的时间状语从句。 [3]本句为but连接的并列句，but后的分句中包含部分否定。 [第一部分　教材助读] Koalas are cute, and we see so many pictures of people holding them. But in many places in Australia, it is against the law to even touch them. Can you clarify⑫ that? [4]They are really quite cute, but the truth is, koalas are very sensitive creatures who can easily panic⑬ because of even small changes in their environment. They spend quite a lot of time eating, [4]本句为but连接的并列句。the truth is后接表语从句；who引导定语从句，修饰先行词creatures。 [第一部分　教材助读] sleeping, and hanging onto tree trunks⑭，so interaction with⑮ humans can cause them a lot of stress. Because of this, the government began to make laws against⑯ touching koalas, in the interest of⑰ animal protection, as well as public safety. So, if you see one in the wild, you shouldn't approach it to pick it up⑱ or even touch it. If you want to [第一部分　教材助读] hold a koala, you have to go to certain licensed⑲ zoos [5]where animal experts make sure that the koalas selected for each session⑳ are in a good state㉑ for human contact and that they are handled㉒ for only a limited㉓ time and on a limited frequency㉔ of occasions． [5]此处为where引导的定语从句，修饰先行词zoos；两个that均引导宾语从句，作make sure的宾语；selected for each session为过去分词短语作后置定语，修饰the koalas。 [第一部分　教材助读] So, we've talked about some cute animals. What about animals which aren't so cute? My favourite is a little creature called the Tasmanian devil. If you are out camping in Tasmania and come across㉕ one, the experience might scare you! [6]Tasmanian devils hunt at night, so you won't usually see them, but you may hear their loud cries [6]本句为并列句。so和but均为并列连词；when引导时间状语从句。 [第一部分　教材助读] when they are fighting or eating. The noise [7]they make could wake the dead㉖. Frightening! They are about the size of small dogs and look like rather large black rats. They also have a terrible smell! Their diet is mostly㉗ dead animals. Fortunately, despite their name, they are generally not violent㉘ towards people. [7]此处为省略关系词的定语从句，修饰先行词The noise；wake the dead运用了夸张的修辞手法。 [第一部分　教材助读] Australia also has some animals that many people have never heard of, for example, the duck-billed platypus. Is that some kind of bird? Not at all. [8]While it may lay eggs in a nest㉙ like a bird, it's really a primitive㉚ mammal㉛， with a unique biology㉜. Its eggs hatch㉝ after about ten days, and then the baby platypus nurses㉞ from its mother [8]此处为while引导的让步状语从句。 [第一部分　教材助读] like all other mammals. Its nose looks like a duck's bill㉟， and it has feet like a duck's so it can dive under the water, but it's covered in hair. Do you know what's really strange about a platypus? The platypus doesn't use its senses of sight or smell to find food. It has a capacity㊱ to find food in the water by using electrical sensors in its bill. There are only a small handful of㊲ animals in the world [9]that can do that! [9]此处为that引导的定语从句，修饰先行词animals。 [第一部分　教材助读] 澳大利亚神奇的动物 我们今天的话题是“澳大利亚特有的生物”，由野生动物专家吉姆·史密斯博士回答问题。 澳大利亚拥有众多独特的动物，但哪种动物才是这个国家的象征呢？ [第一部分　教材助读] 那必须是袋鼠，因为这种动物广泛分布于全国。袋鼠是一种强壮的动物，生存于恶劣的环境中。此外，它不会倒退行走，所以它总是勇往直前。这表达了澳大利亚人作为个体和民族的力量与决心。袋鼠宝宝出生时只有两克重。然后，它们会钻进它们母亲的育儿袋——一种口袋——以保持安全和温暖。它们在这个临时性、受保护的环境中睡觉和吃奶，直到七八个月大。在这个阶段之后，它们会出去试试自己的腿力。学会跳跃之后，它们与母亲相处的时间就会逐渐减少，并 [第一部分　教材助读] 学会独立。袋鼠可能看起来十分可爱，但与它们邂逅的结局并不总是那么美好。袋鼠的踢打相当有力，所以大家要注意，如果你们看到袋鼠，要记住它们不是用来抚摸的！ 考拉非常可爱，我们可以看到很多人抱着它们的照片。但是在澳大利亚的许多地方，即便触摸一下它们都是违法的。你能说明一下这点吗？ [第一部分　教材助读] 考拉确实十分可爱，但事实是，考拉是非常敏感的动物，即便只是环境中的微小变化都会让它们惊慌失措。它们大部分时间都在吃东西、睡觉和挂在树干上，所以与人类互动会给它们带来极大的压力。因此，政府开始立法禁止触摸考拉，这也是出于对动物保护和公共安全的考虑。所以，如果你在野外看到一只考拉，你不应该靠近它去把它抱起来，甚至不应该去触摸它。如果你想要抱一抱考拉，你必须去 [第一部分　教材助读] 那些获得正式许可的动物园，在那里动物专家会确保为每场互动而选出的考拉状态良好，可以与人接触，而且只在有限的时间内，以有限的次数与人互动。 我们已经讨论了一些可爱的动物，那么，不太可爱的动物有哪些呢？ [第一部分　教材助读] 我最喜欢的是一种被称为塔斯马尼亚恶魔的小动物。如果你在塔斯马尼亚野外露营时遇到一只，那经历可能会吓到你！塔斯马尼亚恶魔在夜间捕食，所以你通常不会看到它们，然而当它们打架或者吃东西时，你会听到它们震耳的嚎叫声。它们发出来的噪声能把死人叫醒。太可怕了！它们的个头跟小狗差不多，看起来像大黑鼠。它们身上还有一股难闻的气味！它们的食物主要是动物的尸体。幸运的是，尽管它们名为“恶魔”，但是它们基本上对人类没有攻击性。 [第一部分　教材助读] 澳大利亚还有一些许多人从未听说过的动物，例如鸭嘴兽。那是某种鸟吗？ 完全不是。虽然它可以像鸟一样在巢中产卵，但它实际上是一种原始的哺乳动物，具有罕见的生物特性。它的蛋大约十天后孵化出来，然后新生鸭嘴兽像其他所有哺乳动物一样由母亲哺乳。它的鼻子看起来像鸭嘴，脚也与鸭子的一样，所以它可以潜到水下，但它浑身都是毛。你知道鸭嘴兽真正奇怪的地方是什么吗？鸭嘴兽并非用视觉或嗅觉来觅食。它拥有一种通过用嘴里的电传感器在水中找到食物的能力。世界上具备这一能力的动物屈指可数！ [第一部分　教材助读] $
