Pre-task preparations

1．把全班分成男女生各一组，快速出示Look and learn中的水果单词卡片，请一组中的学生S1大声念出该单词，再请另一组的学生S2说出能描述该水果的两个形容词。两个学都说对了，每组各得一分；如果说错则不得分，哪个小组得分最高获胜。

T: (show the picture of a watermelon)

S1: It's a watermelon.

S2: It's big and sweet.

2．请每个学生给他们最喜欢的一种水果编一则谜语，然后请部分学生说一说，其他学生猜猜他们说的是什么水果。

S1．It's red and small. Smell it. It has a nice smell. Taste it. It's sweet and a little sour. What fruit is it?

S2: Is it a strawberry?

S1: Yes, it's a strawberry.

While-task procedures

1．出示西瓜汁、葡萄汁等果汁，并把它们分别倒进透明杯子里，一边倒，一边向学生介绍是什么果汁。

T: (point to the watermelon juice) This is the juice from a watermelon. What juice is it?

S1: It's watermelon juice.

依次介绍各种果汁，并带领学生朗读词组watermelon juice, strawberry juice 等。

2．用录音机播放海浪的声音，在黑板上画一张大海边的图，给学生创设一个炎炎夏日在海边的情景。

T: Use your imagination. It's a hot summer day. You are at the beach. The sun is hot. You are hot and thirsty. But, look! I have a lot of fruit juice here. What kind of fruit juice do you want?

S1: I'm thirsty. I want some orange juice.

S2: I'm thirsty too. I want some grape juice.

3．播放Listen and say的录音，请学生逐句跟读，模仿录音中的语音语调。然后让学生看图回答问题。

T: (point to the glass of orange juice in Picture 1) This is a glass of juice. What color is the juice?

Ss: It's orange.

T: What is it? Is it grape juice or orange juice?

Ss: It's orange juice.

把核心句型Is it ...or...? 写在黑板上，让学生朗读数遍。然后拿出几杯果汁，让学生通过看颜色、闻气味、尝味道，分辨果汁的类型并回答问题。

T: (point to the grape juice) What's this?

S1: It's purple. Is it grape juice?

T: Yes, it is. (point to the peach juice) Smell this. How does it smell?

S2: It's nice.

T: (show a glass of pear juice and a glass of grape juice) It's sweet and white. Is it pear juice or grape juice?

然后请学生拿出预先准备好的食物，模仿Play a game中的两个女生和同桌一起玩猜谜游戏。

(S1 holds one item and puts his/her hand behind his/her back.)

S1: Close your eyes. Smell it. Is it a biscuit or candy?
