Step l:Revision&Warming up
建议1：通过师生问答进行自由交际。教师向学生提问有关动物的问题，然后让学生回答，通过师生问答可以训练学生的口语交际能力，使学生能够体会到成功的喜悦。 For example:
T:Are there any animals in your house? Sl: Yes,there are. /No,there aren't. T:What animals do you like best? Sl：I like monkeys.
T:Why do you like monkeys? Sl:Because they are very clever.
建议2：谈论动物的图片。教师可以利用多媒体或卡片向学生呈现一些动物的图片，然后让学生根据图片内容进行对话练习。
For example:
T:Look at the pictures. Please work in pairs. Sl:Look at Picture l.What are they? S2:They are giraffes. Sl:Do you like them? S2:Yes,I do.
Sl:Why do you like them?
S2:Because they're tall and interesting. 建议3：通过歌曲让学生热身。

What animals do you like? What animals do you like? Do you like pandas? Yes,I do. Yes,I do. Do you like tigers? Yes,I do. Yes,I do. Do you like elephants? No,l don't. No,I don't.
Step 2:Present the new words
建议1：首先向学生展示一组中国、澳大利亚、南非的地图，根据地图进行对话活动，学习三种动物的栖息地Australia,South Africa and China。
For example:(Show students the map of China,Australia and South Africa) T:Look at the map! Which country is it? Ss:China.
T:Good! And which country is it? Ss:Australia.
T:What about this country?
T:Yes,you are right! It's South Africa. Read after me,South Africa. Ss:South Africa.
建议2：教师通过多媒体课件向学生展示澳大利亚地图、南非地图等，同时出示狮子等动物的图片，引出Australia,South Africa and China。
For example:
T:Which country is this? Can you tell me in Chinese?
Ss:“澳大利亚”．T:You are right. It's Australia. Read after me,Australia. Ss:Australia.
T:Which country is this? Can you guess?
Ss:“南非”．T:You are right. It's South Africa. Read after me,South Africa. Ss:South Africa.
（教师可以采用此法呈现本课时其他的词汇。）
NStep 3:Practice the new words
建议1：教师呈现有关本课时动物以及澳大利亚、中国、南非的有关图片，然后让学生用英语说出该图片中动物的名称以及来自哪里。 For example:
T:I.ook at the picture. What's this in English? Ss：Lion.
T：Spell it，please.
Ss:L-I-O-N.
T:Good. Where are they from? Do you know? Ss:Yes. They're from South Africa. T:Do you like them? Ss:Yes，I do.
T:Why do you like them?
Ss:Because they're kind of scary.
（教师可以采用此法操练本课时其他的词汇，然后让学生与学生之间操练。） 建议2：通过猜谜语的方式巩固所学的新单词。
利用多媒体课件演示有关熊猫、狮子、考拉等动物的叫声让学生猜猜是哪种动物，并且让学生猜出它们的栖息地。通过这个游戏可以充分调动学生的学习积极性，并强化记忆。 For example:
T:Listen carefully. Some animals are crying. Listen and tell me what they are. Do you know?
Ss: Lions．T:Where are they from? Do you know? Australia? South Africa? Or China7Ss:South Africa.
T:Good. Very clever. How about those animals? （教师可以采用此法练习巩固本课时其他的词汇。）
建议3：也可以通过做连线题对学过的词汇进行强化训练。让学生把动物和他们的栖息地连起来。
Step 4:Listening practice
1．在学生对本课时的单词充分掌握的基础上，教师让学生做听力练习，听2。部分并按要求完成填空和连线任务。
2．听听力并用2a中的单词完成2b部分，从而对词汇进行进一步的操练和巩固。
3．让学生跟读录音，目的是让学生能够准确读出并运用新词汇，为下一步的同伴表演打下良好的听说基础。
~Step 5:Present the conversation教师通过与学生谈论有关动物的一些问题，引出如下句型“Why do yo。like.…？”
“Because they're.”??Where are they from???“They're from.,,For example: T:Who can read the conversation in 2b?
S1：…T:Thank you. Use the words in the boxes to make a conversation with a student. For example:
T:Do you like koalas? Sl:Yes，I do.
T:Why do you like them? Sl:Because they're very cute. T:Where are they from? Sl:They are from Australia.
T:Which pair can act out your conversation?
SA：… SB：… （教师用同样的方式谈论其他的动物）Step 6:Practice the conversation 建议1：让学生用2a/2b中所提供的词汇和句型编写对话，来操练2b。
For example:
Sl:Let's see the elephants. S2:Why do you like them?
Sl:Because they're kind of interesting. S2:Where are they from?
Sl:They are from South Africa. 建议2:Act out the dialogue.
让学生与同伴分角色表演2b中的对话，使学生熟练掌握听力材料中的句型，为进一步的学习打下良好的基础。
建议3：用多媒体向学生呈现一组图片，师生根据图片进行问答，然后让学生同伴之间编个新对话并表演。
For example:
T:I.et's see the pandas! Sl:Why do you like them?
T:Because they're kind of interesting. Sl:Where are they from? T:They are from China.
建议4：设计一个关于动物及其栖息地国家的表格，让学生独立完成，目的在于让学生了解世界上一些国家所特有的动物是什么，进一步增强学生热爱大自然，保护珍稀动物的信念。
Animal Pandas Lions Where are they from? China South A f rica Koalas Elephants Australia India 注：标斜体部分可以作为空格考查用。
利用上面表格中内容，编写一个与动物栖息地相关的对话，从而达到训练本课时句型的作用。并在此基础上进一步完成3a的填空内容。然后，和同伴两人一组分角色表演此对话。 For example:
SA:Where are lions from?
SB:They're from South Africa. Do you like lions? SA:No，I don't．SB:Why don't you like lions?
SA:Because they're really scary. But I like giraffes.
建议5：做猜谜游戏。请一位学生描述一种动物的特征及其栖息地，让另外一位同学猜猜是什么动物？通过此游戏使学生对单词和句型进行进一步的巩固，达到学以致用，寓教于乐的教学目的。
For example:
Sl:Is the animal big?
S2：Yes,it is．Sl:Where's the animal from? S2:lt's from China．Sl:Is it black and white? S2：Yes,it is．Sl:It's a panda!
S2:Yes,you're right!
（让学生尽情地自由发挥，争先恐后地加入到此次活动中，在活动中交流中进步。） Step 7:Make new dialogues according t0 2c and practice them
建议1：根据2c中的要求，让学生用2a/2b中所提供的词汇和句型编写对话，来操练新句型。

Sl:Because they're kind of interesting/too big. T:Do John and Julie like elephants? Sl:Yes,they do./No,they don't. T:Why( not)?
Sl:Because they're kind of interesting/too big. 建议2:Act out the dialogue.
让学生与同伴分角色表演2c中的对话，使学生熟练掌握听力材料中的句型，为进一步学习打下良好的基础。
建议3：用多媒体向学生呈现一组图片，师生根据图片进行问答，然后让学生同伴之间编个新对话并表演。
For example:
T:Do John and Julie like pandas? Sl:Yes,they do. /No,they don't. T:Why( not)?
Sl:Because they're kind of/not interesting. Step 8:Play a game
