It's a tough 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 resolve of the Australians as individuals and as a nation. Baby kangaroos weigh only two grammes at birth②. They then find their way into their mother's pouch③—a kind of pocket—to stay safe and warm. They sleep and drink milk in that temporary④， protected environment until they are about seven or eight months old. After this phase⑤， 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. Kangaroos may look cute, but encounters⑥ 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 petting! 句中that引导定语从句，修饰animal。 句中protected是过去分词作定语，修饰environment。 ①distribution/ˌdIstrI'bjuːʃn/ n．分布；分配；分发 ②at birth 出生时 ③pouch/paʊtʃ/n.育儿袋；小袋子；荷包 ④temporary/'temprəri/adj. 暂时的；短暂的 ⑤phase/feIz/n.阶段；时期 ⑥encounter v．遭遇；邂逅；遇到n.遭遇；偶然碰见 答案肯定是袋鼠，因为它在全国范围内分布广泛。它们生命力顽强，能在艰难的环境中生存，而且它们无法向后退，只能向前跳，这体现了澳大利亚人和这个国家的力量和决心。袋鼠宝宝出生时只有两克重，之后它们会钻进一种口袋，即妈妈的育儿袋里，这样既安全又暖和。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，它们会从育儿袋里出来，试着站起来。学会跳跃后，它们和妈妈在一起的时间会逐渐减少，并学着独立起来。袋鼠可能看起来很可爱，但和它们相遇后的结局并不都是那么好。袋鼠踢打人会很疼，所以请大家注意，如果你们看到袋鼠，一定记住，它们可不是用来抚摸的！ 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 clarify⑦ that? ⑦clarify v．澄清；阐明 考拉很可爱，我们见过很多人抱着考拉的照片。但在澳大利亚的许多地方，就连摸它们都是违法的。你能解释一下吗？ They are really quite cute, but the truth is, koalas are very sensitive creatures who can easily panic because of even small changes in their environment. They spend quite a lot of time eating, sleeping, and hanging onto tree trunks⑧， so interaction⑨with humans can cause them a lot of stress. Because of this, the government began to make laws against touching koalas, in the interest of⑩animal protection, as well as public safety. So, if you see one in the wild, you shouldn't approach it to pick it up or even touch it. If you want to hold a koala, you have to go to certain licensed zoos⑪ where animal experts make sure that the koalas selected for each session⑫ are in a good state for human contact and that they are handled for only a limited time and on a limited frequency⑬ of occasions. 句中where引导定语从句，修饰certain licensed zoos；selected for each session是过去分词短语作后置定语；make sure后接两个并列的宾语从句。 ⑧trunk/trʌk/n.树干 ⑨interaction n.相互作用，相互影响；交流 ⑩in the interest of 为了……的利益 ⑪licensed zoos 有执照的动物园 licensed/'laIsnst/adj.得到正式许可的 license/'laIsns/vt.批准；许可；n.(＝licence)许可证；执照 ⑫session/'seʃn/n.一场；一段时间；会议 ⑬frequency /'friːkwənsi/n.发生率；重复率；(声波或电磁波振动的)频率 它们真的很可爱，但事实上，考拉是一种非常敏感的生物，它们很容易因为环境的细微变化而受到惊吓。大多数时间它们都在吃饭、睡觉或挂在树干上，所以与人类的互动会给它们带来很大压力。因此，政府开始制定法律，禁止人们触摸考拉，这是为了保护动物和公众安全。所以，如果你在野外看到考拉，不要试图靠近它把它抱起来，更不要触摸它。如果你想抱一下考拉，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。 So, we've talked about some cute animals. What about animals which aren't so cute？ 句中which引导定语从句，修饰animals。 我们已经谈论了一些可爱的动物，那么能说说那些不那么可爱的动物吗？ My favourite is a little creature called the Tasmanian devil. If you are out camping in Tasmania and come across one, the experience might scare you! Tasmanian devils hunt at night, so you won't usually see them, but you may hear their loud cries when they are fighting or eating. The noise they make 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, despite their name, they are generally not violent towards people. 句中called the Tasmanian devil是过去分词短语作后置定语。 句中when引导时间状语从句。 句中they make是省略了关系代词的定语从句。 我最喜欢的是一种叫作袋獾的小生物。如果你在塔斯马尼亚露营时碰到它，可能会吓一跳！袋獾在夜间捕食，所以你通常看不到它们，但可能会听到它们打架或进食时的大叫声。它们发出的声音可以吵醒死人。太可怕了！它们的大小和小狗差不多，但看起来更像是大黑老鼠。它们还有一股难闻的气味！它们主要以动物的尸体为食。还好，尽管它们的名字很吓人，但它们通常不会攻击人。 Australia also has some animals that many people have never heard of, for example, the duck-billed platypus. Is that some kind of bird? 澳大利亚也有一些很多人都没听说过的动物，比如，鸭嘴兽，那是一种鸟吗？ Not at all. While it may lay eggs in a nest⑭ like a bird, it's really a primitive mammal, with a unique biology⑮. Its eggs hatch⑯ after about ten days, and then the baby platypus nurses from its mother like all other mammals. Its nose looks like a duck's bill, 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 capacity⑰ to find food in the water by using electrical sensors in its bill. There are only a small handful of animals in the world that can do that！10 句中while引导让步状语从句。 10 句中第一个that引导定语从句。 ⑭nest/nest/n.巢穴；鸟窝；秘密窝点 ⑮biology /baI'ɒlədʒi/n.生理；生物学 ⑯hatch/hætʃ/vi.孵出；破壳 vt.使孵出；策划；(尤指)密谋 ⑰capacity /kə'pæsəti/n.能力；容量 完全不是。虽然它可能像鸟一样在巢里产卵，但它确实是一种原始的哺乳动物，具有独特的生物学特征。鸭嘴兽的卵需要大约10天时间才能孵化，然后像所有其他哺乳动物一样，鸭嘴兽幼兽靠母乳成长。它们的鼻子看起来像鸭子的嘴，还有像鸭子一样的脚，所以可以潜入水里。不同的是，它们全身长满了毛。你知道鸭嘴兽最奇怪的地方是什么吗？鸭嘴兽不用视觉或嗅觉来寻找食物。它们有一种利用嘴里的电场感受器在水中寻找食物的能力。世界上只有很少的动物可以那样做！ Part 2　语篇研析 Activity 1　文章架构 1．What's the main idea of the text?
