教学重点

教学难点

重点：能听懂、会说、认读单词apple, banana, pear, lemon, range，并能用句型“Is this ...? 询问水果名称并简单作答。

难点：orange这个单词既可作水果名称，又可作颜色单词。冠词a/an学生容易混淆，a用于辅音音素前，an用于元音音素前，让学生在原有的基础上进一步感知a/an的区别以及an orange的连用与连读?

Step 1 Warming up

Greetings.

Sing a song “Are you sleeping?”

Talk freely.

T: Look. What’s this? Ss: It’s a pen. T: Is this a pen? Ss: No, it isn’t. It’s a pencil. …

T: (Using animal cards to ask and answer) Boys and girls, do you know? What’s this? Ss: It’s a cat. T: S1. Is this a cat? S1: No, it isn’t. It’s a dog. T：Is this a/ an …?

（设计意图：师生亲切问候完后齐唱欢快的英语歌曲，让学生很快进入英语学习氛围。自由谈话用学具物品和动物图片进行交流，先全班同学师问生答，然后随便选一小组同学单个回答，目的是复习学过的句型”What’s this?”“Is this a … .” “Yes, it is. / No, It’s not. ”及单词，为新授课做好铺垫 ）

Step 2 Presentation and practice

New words

PPT shows an orange. Ask: What’s this? Do you know? Ss: Sorry, I don’t know. T: OK. Let me tell you. Orange, it’s an orange. Teach and drill orange.(orange, orange, an orange) Read it one by one. Take out an orange and ask: Is this an orange?（揭示课题） Ss will answer: Yes, it is. （板书黑板）T: Who can use it ask others: Is this an orange? Train work in groups. ( S1: Is this an orange? S2: Yes, it is. Is this an orange? S3: … )

（设计意图：紧接着自由谈话的部分直接导出今天学的水果单词orange，自然过度到今天所学的新课，在“Train work”中学生运用实物组内操练句型和单词，很好地练习了重点句型。）

PPT shows a red apple and ask: Is this an orange，too? Ss: No, it isn’t.(板书黑板) Teach and drill “apple” (apple, apple, an apple) T：I like this apple./ I like apples.

Game--Quick response (Using an orange and an apple to hide the back and ask Ss say out correctly. Ask and answer quickly.)

Tips: an用于以元音因素开头的单词前面。

（设计意图：由单词orange引出新词apple，在游戏Hide and guess操练时学生非常感兴趣，并在PPT上呈现Tips让学生明白an的用法。）

(Take out a pear and ask): Is this an apple, too? Ss: No, it isn’t. T: What’s this? Help answer: It’s a pear. (follow me to write) Teach and drill “pear”(High and low voice; Little teacher ) PPT show a pear and a ?, Who can ask? Call several Ss to ask with: Is this a pear?
