拓展：本篇是本單元所有拓展內(nèi)容，并不是一天的，基本分散在每天一點(diǎn)點(diǎn)的狀態(tài)。一、蝸牛蝸牛是從一出生就背著殼的。殼會(huì)隨著蝸牛長(zhǎng)大而長(zhǎng)大，直到蝸牛成年，殼才會(huì)停止生長(zhǎng)。SnailSnail is a small soft creature with a hard round shell on its back, that moves very slowly and often eats garden plants. Some types of snail can be eaten. As the snail continues to grow, its shell grows with it. 觀察一下真實(shí)的蝸牛 蝸牛喜歡吃菜葉吃東西的樣子哪個(gè)是tentacle？哪個(gè)是眼睛？嘴巴在哪里？復(fù)習(xí)：tentacle 觸角、shell、muscular ['m?skj?l?r]肌肉發(fā)達(dá)的 foot、mucous[?mjuk?s] 粘液 蝸牛會(huì)保護(hù)自己，懂得找深色的地方躲藏 二、蝸牛與龜?shù)南嗤?lt;/p>What's does a turtle and snail have in common?They both have shells on there backsThey both use there shells for protectionThey both need water in some way.They are both animals. 三、其他的爬行動(dòng)物有哪些？一起來(lái)看看，另外恐龍也是爬行動(dòng)物哦 四、Life cycle of turtles 海龜?shù)纳h(huán)Mother turtles lay eggs, they hatch to become babies (or hatchlings), then they become juveniles[?d?uv?n?lz]未成年, and after that they become adults. Let's learn more about each phase[fe?z] 階段Sea turtles have big front flippers.  1、Turtles Begin as EggsThe life cycle of turtles begins with female sea turtles lay eggs. Sea turtles lay their eggs in the sand on the beach.They can lay a nest of 100-200 eggs. Eggs hatch in 40 to 60 days, depending on the species物種. The mothers dig holes in sand or mud to lay their eggs in a safe nest and bury [?beri] them 把它們埋起來(lái). This protects the eggs from predators[?pr?d?t?rz] 捕食者. The eggs are then left there from spring to summer to grow and become babies. Many turtle species [?spi??i?z] 物種take about three months to hatch. Turtle eggs are shaped like 形狀像 ovals [?o?v?lz] 橢圓形, and they're a little softer than other animals' eggs. An interesting fact is that some species of turtles have eggs that become male or female based on the temperature of their nests.一個(gè)有趣的事實(shí)是，一些種類的海龜?shù)穆褧?huì)根據(jù)它們巢穴的溫度變成雄性或雌性。（這塊本次沒(méi)有拓展到，下次再用） 大海龜下完蛋會(huì)把蛋埋上用小光片當(dāng)埋蛋了 來(lái)看看真實(shí)的海龜?shù)鞍?，怎么知道已?jīng)受精了，照照光會(huì)有紅血絲。怎么孵化小龜呢？來(lái)學(xué)一學(xué)方法，自己體驗(yàn)一下吧 龜?shù)氨绕渌焉鷦?dòng)物蛋要軟 龜?shù)笆怯姓吹?，需要正確地面向上面 要蓋足夠厚的蛭石才可以孵化 每天都要噴水，但是一定不要噴到蛋和沒(méi)下水的小龜上面 2、The Next Stage: Hatchlings 剛出殼的小動(dòng)物The next phase in a turtle's life cycle is called the hatchlings phase. This is when baby turtles peck 啄their way out of the eggs. And they begin trying to survive on their own. Baby turtles, or hatchlings, are completely independent 獨(dú)立的at birth and never see their mothers.As soon as they come out of the nest, hatchlings crawl as fast as possible to the sea and swim towards the open ocean.剛從巢里出來(lái)，小海龜就盡快地爬到海里，游向大海。Can you imagine a baby human getting its own milk and protection? Baby humans cannot survive on their own without a person caring for them.設(shè)想一下小寶寶們出生時(shí)However, the mother turtle is not there to protect and teach the hatchlings how to survive.Baby turtles on land and on the sea are in danger of predators eating them before they can grow up. 剛孵化的小龜hatching 3、 Juvenile[?d?u?v?nl]小海龜As young (or juvenile) turtles, they head out to sea. From there, in many cases, we don’t know where they go (that’s why we call them “the lost years.”)當(dāng)小海龜(或幼海龜)出海時(shí)，它們會(huì)游向大海。從那以后，很多情況下，我們不知道它們?nèi)チ四睦?這就是為什么我們稱它們?yōu)椤笆サ臍q月”)Young turtles spend several years drifting with the currents (often referred to as the lost years), feeding on small animals living in algae floating in the water小海龜花了好幾年的時(shí)間隨波逐流(通常被稱為“失落的歲月”)，以漂浮在水中的海藻中的小動(dòng)物為食。After a few years, immature turtles will settle close to shore where it may take them more than 30 years to reach adulthood.幾年后，未成熟的海龜會(huì)在岸邊定居，在那里它們可能需要30年以上的時(shí)間才能成年。The time juvenile turtles spend on growing areas varies according to the species and food availability.小海龜在生長(zhǎng)區(qū)域所花的時(shí)間因物種和食物供應(yīng)的不同而不同。Once they are fully grown, they head back to where they were born to mate交配.  4、Life as an Adult TurtleAdult turtles can live on either land or water. They can stay underwater for long periods of time but must emerge for air every so often because they have lungs [l??z] 肺instead of gills 腮like a fish. 成年海龜既能生活在陸地上，也能生活在水中。它們可以在水下待很長(zhǎng)一段時(shí)間，但必須經(jīng)常出來(lái)?yè)Q氣，因?yàn)樗鼈兿耵~一樣有肺而不是鰓。Turtles that live primarily on land often dig holes in the dirt with their strong, rough [r?f] 粗糙的feet to keep cool. They also stay inside their shells to both protect their bodies from drying out and to be safe from predators. 五、海龜和陸龜Turtle & TortoiseTurtle is one of the oldest reptile 爬行動(dòng)物groups and a more ancient group than snakes or crocodilians.海龜是最古老的爬行動(dòng)物之一，比蛇或鱷魚目動(dòng)物更古老。Turtles are reptiles with hard shells that protectthem from predators.Turtles live all over the world in almost every type of climate.海龜幾乎生活在世界各地各種氣候條件下。 HabitatTurtles 海龜Turtles live almost exclusively in the water. The only time they come to land is to lay eggs, but the mother will quickly abandon [??b?nd?n] 遺棄her young and return back to the water, leaving the turtle hatchlings [?h?t?l??] 剛出殼的小動(dòng)物 alone from birth.（leave from…從…離開） Tortoises[?t??rt?s] 烏龜Unlike turtles, tortoises are terrible swimmers 糟糕的游泳者 and live on land. Tortoises are land animals. Mother tortoises will provide protection to their young hatchlings for around 80 days after birth-after which they survive [s?r?va?v] 生存on their own. Physique [f??zi?k] 體形TurtlesBecause they spend so much time in the water, a turtles body is streamlined [?stri?mla?nd] 流線型的. They also have flippers, webbed [webd]有璞的 feet, and long claws[kl??z] 爪.TortoisesTheir feet are round and stumpy[?st?mpi]短而粗的, adapted for walking on land. They also dig holes with their strong forelimbs前肢.Tortoise shells are shaped like a circle and are incredibly sturdy[?st??rdi] 堅(jiān)固的, to help protect them from predators[?pr?d?t?rz]捕食者. They tend to 傾向于have short, sturdy feet with long claws to help them with digging. 龜殼的作用特別大，遇到危險(xiǎn)可以縮回殼里，保護(hù)自己，防御天敵predators，這個(gè)詞predator好難理解啊，看到寶寶頭上的?，我拿出了小鱷魚，告訴他鱷魚喜歡吃小龜和龜?shù)?，?duì)于龜來(lái)說(shuō)，就是predators Diet[?da??t] 日常飲食TurtlesTurtles are omnivores雜食動(dòng)物-meaning they eat both vegetation and other animals. As well as vegetation, they have been known to feed on 以…為食，small fish, jellyfish, and insects such as earthworms.TortoisesMost tortoises are herbivores食草動(dòng)物, surviving on 靠…生存 vegetables, fruits, grass and flowers. Some tortoise are thought to consume up to 200 different types of plants in one year. 有些龜一年可以消耗200多種植物 來(lái)猜一猜海龜和烏龜分別喜歡吃什么？ 海龜喜歡吃小魚和海草，是雜食動(dòng)物，烏龜只吃植物，是食草性動(dòng)物，聯(lián)系到了以前的知識(shí)點(diǎn) Lifespan壽命TurtlesSea turtles have an average lifespan of 60 to 70 years. The lifespan of the common turtle is between 20 and 40 years.TortoisesIn contrast相比之下, tortoises can live to be around 80 years old, some can live for over 150 years. Experts say it is possible for most tortoises to live for over 100 years, but living beyond that would require "carefully controlled, nurturing environments.專家們說(shuō)，大多數(shù)龜都有可能活到100歲以上，但要活到100歲以上，就需要“精心控制和養(yǎng)育環(huán)境”。The world's oldest tortoise is 183-year-old. 直接說(shuō)英文數(shù)字，不容易明白，我拿出了數(shù)字塊，非常直接的能看出來(lái)他們壽命的長(zhǎng)短 183歲有多長(zhǎng)？比兩個(gè)太姥的年齡還要大，比三個(gè)姥姥年齡還要大，想象一下吧？這樣說(shuō)孩子可能更容易理解龜?shù)拈L(zhǎng)壽 總結(jié)：這一單元都是小動(dòng)物，孩子天性就很喜歡，我們養(yǎng)了小蝸牛，開始學(xué)習(xí)孵化小龜，每天觀察他們，是一件特別有趣的體驗(yàn)！后面很硬殼的生命循環(huán)一塊，有很多知識(shí)性的，我擔(dān)心不好理解，于是用了小模型，模擬還原了小龜?shù)囊簧?lt;/p>還有烏龜和海龜，我自己原來(lái)也分不清，這回詳細(xì)解釋了他們的不同，這塊硬科普很生澀，直接拿來(lái)讀給孩子，估計(jì)孩子都會(huì)想直接跑掉，耐心好的，聽完估計(jì)也是一腦袋星星?。我準(zhǔn)備了他們的模型，打印了圖片，準(zhǔn)備了一些小道具，非常直接的就能讓孩子自己發(fā)現(xiàn)感受他們的不同。比如，飲食上，拿出幾個(gè)不同的食物模型，就能直觀看到兩種龜吃的不同；年齡這塊更是，我直接說(shuō)sixty、eighty……他分不清楚大小，把數(shù)字卡放在眼前，哪個(gè)大哪個(gè)小，誰(shuí)活得久，一目了然。最后期待我們小龜孵化的那一天！
