【教学过程】
I. Pre-task preparations
1．播放Sing a song的录音，让学生欣赏歌曲Apple tree。
2．教师引入话题，让学生了解今天讨论的是关于食物的话题。出示一个布袋，布袋里放有食物，让学生摸一摸，猜一猜里面有什么。食物可以从学生已知的苹果、橘子到糖果、柠檬，引出本单元的单词candy和lemon。
T: What is it?
S1: It's an apple / a lemon / candy /... II. While-task procedures
1．利用单词卡片或实物教学新单词，让学生跟读并拼读单词。 T: (show the flashcard for candy) What is it? Ss: It's candy.
T: Candy. C-A-N-D-Y, candy. Ss: Candy. C-A-N-D-Y, candy.
提醒学生注意candy是不可数名词，不可以说It's a candy. T: (show the flashcard for ice cream) What is it?
1 / 3
Ss: It is an ice cream. T: An ice cream. Ss: An ice cream.
提醒学生an ice cream仅用来表示甜筒冰淇淋或杯装冰淇淋，如果是盒装冰淇淋，不能说 an ice cream，而要说ice cream。
2．词汇巩固。通过True or false或者Instant memory等游戏帮助学生巩固新单词的发音和词义。
True or false:
T: (show the flashcard for lemon) An apple? Ss: (clap hands) A lemon.
T: (show the flashcard for lemon) A lemon? Ss: A lemon. Instant memory:
T: (show the flashcard for lemon)
S1 / S2: (have a match to see who says the word faster) Lemon.
3．句型导入。教师出示柠檬或糖果，让学生品尝，通过提问引入新句型How is it? It's sweet/ sour，让学生跟读新句型，并提醒学生注意两个句型What is it?和How is it?的不同含义。
T: What is it?
Ss: It's a lemon. / It's candy. T: Taste it. How is it? S1/T: It's sour. / It's sweet.
用脸部表情图片帮助学生理解sweet和sour的词义。出示更多食物的实物或把挂图贴在黑板上，让学生进行小组问答活动，操练How is it? It is sweet/ sour. 句型。学生可以在食物图片旁边用图示（如笑脸和哭脸）或单词(sweet/ sour)来表示味道。
S1: How is it? S2: It's sour.
4．播放Listen and say的录音，让学生听并跟读。然后让学生朗读Listen and say的对话。 III. Post-task activities
1．Look and talk: 看图说话。发给每个学生一张或两张食物图片。让学生在教室里走动，根据图片和同学自由问答，答对的一方可以获取对方的卡片。
S1: (show the picture of a lemon) Look, what is it?
2 / 3
S2: It's a lemon. S1: How is it? S2: It's sour.
S1: Yes. (Give the picture to S2)Here you are. S2: Thank you.
2．创设派对场景，让学生仿照Listen and say的对话，利用卡片或者实物进行情景对话。上一个Look and talk 游戏中出现的主要是新词汇，而在这个游戏中可以将词汇更丰富一些，加上学生已知的单词。如果要使用句子Taste it，建议用实物让学生有真正的品尝过程；如果出示的是图片，那么学生在交流中可假装品尝一下。
S1: Taste it. How is it? S2: It's sour. S1: What is it? S2: It's a lemon. S1: Yes, it's a lemon.
