It has to be the kangaroo，as it has a wide distribution② throughout the country．It's a tough③ 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 resolve④ of the Australians as individuals⑤ and as a nation．Baby kangaroos weigh only two grammes at birth．They then find their way into their mother's pouch⑥—a kind of pocket—to stay safe and warm．They sleep and Period 5　课时练案 课文整体教学(Using Language) drink milk in that temporary⑦，protected environment until they are about seven or eight months old[2]．After this phase⑧，they go out to try their legs．After they learn to jump[3]，they gradually spend less time with their mother and learn to be independent．Kangaroos may look cute⑨ ，but encounters⑩ with 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 petting⑪！ [2]until用来表示在某个特定的时间之前谓语的动作一直在延续。 [3]after引导时间状语从句。 Period 5　课时练案 课文整体教学(Using Language) 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 clarify⑫that? They are really quite cute，but the truth is，koalas are very sensitive⑬ creatures who can easily panic⑭ because of even small changes in their environment[4]．They spend quite a lot of time eating，sleeping，and hanging onto tree trunks⑮，so interaction⑯ with humans can cause them a lot of stress．Because of this，the government Period 5　课时练案 课文整体教学(Using Language) began to make laws against touching koalas，in the interest of⑰ animal protection，as well as public safety．So，if you see one in the wild，you shouldn't approach⑱ it to pick it up or even touch it．If you want to hold a koala，you have to go to certain licensed⑲ zoos where animal experts make sure that the koalas selected for each session⑳ are in a good state for human contact and that they are handled for only a limited time and on a limited frequency㉑ of occasions㉒． [4]who引导定语从句，修饰先行词creatures。 Period 5　课时练案 课文整体教学(Using Language) So，we've talked about some cute animals．What about animals which aren't so cute？[5] [5]What about用来引述与前面内容相关的话题；which引导定语从句。 My favourite is a little creature㉓called the Tasmanian devil[6]．If you are out camping in Tasmania[7] and come across㉔ one，the experience might scare㉕ you! Tasmanian devils hunt at night，so you won't usually see them，but you may hear their loud cries when they are Period 5　课时练案 课文整体教学(Using Language) fighting or eating．The noise they make[8] could wake the dead．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 mostly dead animals．Fortunately，despite㉖ their name，they are generally not violent㉗ towards people． [6]该处是过去分词短语作名词creature的定语。 [7]该处是动词-ing形式短语作状语。 [8]该处是定语从句，省略了关系代词which或that。 Period 5　课时练案 课文整体教学(Using Language) Australia also has some animals that many people have never heard of[9]，for example，the duck-billed㉘platypus㉙．Is that some kind of bird? [9]该处是定语从句，关系代词that可以省略。 Not at all．While it may lay eggs in a nest㉚ like a bird[10]，it's really a primitive㉛mammal㉜，with a unique biology㉝．Its eggs hatch㉞ after about ten days，and then the baby platypus nurses㉟ from its mother like all other mammals．Its nose looks like a duck's bill，and it Period 5　课时练案 课文整体教学(Using Language) 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 senses㊱ of sight or smell to find food．It has a capacity㊲to find food in the water[11] by using electrical sensors㊳ in its bill．There are only a small handful of㊴ animals in the world that can do that[12]! [10]连词While在这里引导的是让步状语从句。 [11]动词不定式短语作名词capacity的定语。 [12]关系代词that引导定语从句，修饰先行词animals，此处的关系代词that不能用which替换，因为先行词有only修饰。 Period 5　课时练案 课文整体教学(Using Language) 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一无二的动物，但哪种动物才是这个国家的象征呢？ 毫无疑问是袋鼠，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 Period 5　课时练案 课文整体教学(Using Language) 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，它们会钻进母亲的育儿袋——一种口袋——以保持安全和温暖。大约七八个月大之前，它们一直待在那个暂时受保护的环境里睡觉和吃奶。在这个阶段之后，它们会出去试试腿力。学会跳跃之后，它们与母亲相处的时间就会逐步减少，并学会独立。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，所以大家要小心，如果你们看到袋鼠，要记住它们不是用来爱抚的！ Period 5　课时练案 课文整体教学(Using Language) 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，即便碰一下它们都是违法的。你能说明一下这点吗？ 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，也是出于对保护动物和公共安全的考虑。所以，如果你在野外看到一只考拉，你不要靠近 Period 5　课时练案 课文整体教学(Using Language) 它去把它抱起来或甚至不要去触摸它。如果你想要抱一抱考拉，你必须去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。 我们已经谈论了一些可爱的动物，那么，不太可爱的动物呢？ 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 Period 5　课时练案 课文整体教学(Using Language) 者吃东西时，你会听到它们震耳的嚎叫声。它们发出的声音可以吵醒死人。十分恐怖！它们个头跟小狗差不多，看起来像只大黑鼠。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。 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。虽然鸭嘴兽可以像鸟一样在巢中产卵，但它实际上 Period 5　课时练案 课文整体教学(Using Language) 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，脚也跟鸭子的一样，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。它拥有一种能用嘴里的电传感器在水中找到食物的能力。世界上只有很少的动物可以那样做！ Period 5　课时练案 课文整体教学(Using Language) $
