Presentation

1． Learn the new words.

T: Do you love the sea? What’s in the sea? 引导学生说出他们知道的海洋生物，如：fish。由于课本中学过的海洋动物较少，教师创设情境：T: There are many fish in the sea. There are still many other animals in it. Do you want to have a look? Let’s go to Qingdao and get to know some animals in the sea. 用课件呈现一列火车开动及到达青岛站的画面，T: Now we are in Qingdao. Look! 出现青岛极地海洋世界大门的画面，T: Wow! We are going to visit the world of marine animals. But we have to surmount some difficulties and pass through the gates. 出现几道大门。

出现第一道大门及问题：Do you know them? Have a try! T: First, let’s learn something about the animals in the sea. Then we can pass through the first gate. 图片显示几个简单易记的动物名称，帮助学生扩大词汇量，如：sea horse, sea lion。随后出现一系列的海洋生物及他们的英文名称，教学生学习新单词，如：squid, lobster, shark, seal, sperm whale, killer whale, 单词配图逐一呈现，单词上同时出现各词的音标，引导学生注意学过的字母及字母组合的发音， 如: i /i/, qu /kw/, er / /, sh / /, ar /a: /, ea /i: /, er /З: /, wh /w/, 让学生自己先试着用学过的音标知识读出发音，然后教师再教，培养他们运用音标自学的能力。

单词学会后快速认读，较熟练后做游戏: Magic eyes. Who has magic eyes? 各种动物图片快速在屏幕上闪烁，停下来时看谁能最快

说出屏幕上的动物名称，发给最快的学生小粘贴。等读出所有单词时，教师点鼠标，音乐响起，同时大门开启，通过第一道关。可与学生击掌庆贺，增强情境的真实感。

2． Learn the knowledge about the sperm whale.

显示第二扇大门及门上的问题：Do you know something about a sperm whale? If you can fill in the table and answer the questions, you can pass through the second gate. 出现sperm whale 的图片, 教师放事先录好的自制录音，请学生记下听到的数字准备完成表格（如下），并准备回答问题。

It can dive into the deep cold water. 让学生回答问题，教师边填表边说：The length of a sperm whale is 15 meters. The weight of a sperm whale is 35 tons. It has 50 teeth and each up to 20 cm long. 用动作和图片帮助学生理解每个牙齿都达20 cm 长。并教学生读单词，让学生通过联想读出新词：ten, math → length; eight → weight; bee → teeth; ill → kill → skill 。并举例让学生明白skill的意思，如：A monkey can climb trees, so climbing trees is the monkey’s skill. A fish can swim, so swimming is the fish’s skill.

回答完问题、填完表后让学生跟课本录音朗读，并一起朗读，读完后教师点鼠标通过第二道大门。
