四、教学过程：
step 1 warm up
t: we will begin our class now. children, if you do a good job in class, i’ll give you a price. so let’s come on. ok?
[通过给出要求和奖励，提高学生在课上的积极性。]
1.greetings.
2.free talk: hello, what’s your name? how are you? what can you do?
[通过日常对话营造英语课氛围，并复习已学句型what can you do?为新授句型what can you see?做铺垫。]
3.sing a song: at the market.
[通过歌曲激发学生兴趣，歌曲中的we can see…句型也为下面的新授句型i can see…做了准备。]
step 2 presentation
1.teach the sentences.
a. t: what can you see in the market?
[让学生回答歌曲中出现的东西，自然引出新授句型what can you see？也易于学生理解。]
b. t: children, it’s ten o’clock at night. it’s dark. we can hear some voice in the market. let’s go and have a look. ok? 同学们，现在天黑了，超市里有声音，我们去看看超市里有什么好吗？please listen to my question carefully. what can you see in the market? you can say’ i can see …’
[通过透视镜功能吸引了学生的注意，让学生能集中注意力去看东西，进行新授句型的学习。]
2.teach ‘plane’
t: let’s play a guessing game. what’s this? guess. oh, it’s a plane. children, if you are happy, how do you read this word? (sad/ angry/ surprise/ …) we also can call it airplane. where can we see the planes? (airport)
[用让学生猜谜的游戏能调动学生积极性，并通过擦除功能一点点展现图片，使学生能完全跟着老师走。在读新单词时采用让学生使用不同的情绪来读单词，使单词学习人性化。]
3.teach ‘boat’
show a picture
t: look, here’s a picture. what can you see in the sky? (plane, kite) what can you see in the river? (duck, boat)
[把单词和句型结合在一起操练学习，并为新单词的引出做了铺垫。]
t: oh, how to read this word? can you read this word? (coat—boat)
t: 现在让我们模仿小动物的声音来读这些单词
t: read the word as a cat….
t: here’re some boats. let’s learn how to read them. (duck boat, sail boat, dragon boat)
[让学生通过已学单词自己说出新授单词的发音，并通过模仿不同小动物的声音来操练新单词，增加他们的兴趣。再进行单词的拓展训练。]
4.teach ‘train’ ‘jeep’
t: now, let’s play a game ‘listen and guess’
  can you make sentences with the word? for example: i can see a long train.
[通过听声音猜单词的方式来学习新单词，学生比较感兴趣。而且让学生再进行造句的练习，把单词和句型结合在了一起。]
