一、走进情境 体验语用

Well begun is half done. 在导入环节，教师结合文本内容为对话教学创编一个背景对话作为先行组织者，让学生浸润于一个相对完整的语言情境中更好地感知语言、理解语言和体验语言，从而为对话教学做好铺垫。

小学英语对话课堂是基于对话交流的课堂教学形式，在进入文本对话前，教师根据情境发展需要，铺垫一个小对话，解决若干语言点，直至与文本会话对接。

【案例1】译林小学英语五年级下册《unit8 Birthdays》一课通过谈论苏海苏阳和Mike的生日对话展现核心句型“...’s birthday is on the ... He usually ...s”的语义和语用情境。

教师在教学对话前以文本对话为导向，创设与课文对接的情境，借以铺垫重点句型。

情境1：T : There are twelve months in a year. Which month do you like? Why?

B: I like January. Because spring festival is in January. People usually get together with their families and have a big dinner. After that, we play with our toys.

通过以上情境，激活了学生旧知，铺垫了新的语言点，为后续“生日”情境顺畅自然。

情境2：T: What day is it today?It's ...

T: What date is it today? It’s the ...

T: What months do you like?I like December,because my birthday is in December. We eat noodles.

T: When is your birthday?

此情境出示后，教师通过引入日期和生日，促进学生对情境的感悟和理解，帮助学生正确运用序数词和“生日”语言。

情境3：T：What do you usually do on your birthday?

S：I usually eat noodles and a birthday cake. Sometimes I have a party at home.

以上三个情境中对话的话轮是以递进形式呈现，每个对话都是完整的意义块，对语言点的解决起到情境暗示作用。
