【教学重难点】
1．教学重点
（1）能用“Hw many …are there in…?”询问一年有几个季节，并用“There are…”做出回答。
（2）能够理解、认读词汇seasn。
2．教学难点
（1） 问句“Hw many seasns are there in a year?”中的are there不能丢掉。

【教学过程】
导入
1．T: Tday we are ging t learn Unit 6 Which seasn d yu like? First, let’s play a guess game, a wrd guess game.
教师出示两组春夏秋冬的图片，让学生来猜“季节”这个单词。因为是seasn是本节课所要学习的新单词，因此教师应把重点放在学生对这一抽象单词的理解上，可以启发学生用汉语说出“季节”这一单词。
2．如果两组图片过后，学生还是不能理解seasn的含义，PPT播放Lessn 23小韵文Spring is bright, with flwer and sng. Summer is ht, and the days are lng. Autumn is rich, with fruits and grain. Winter brings snw, and a new year again.
T: What d yu hear in this chant? D yu hear spring/summer/autumn/winter?
S: Yes.
T: Spring/summer/autumn/winter is a seasn, s there are fur seasns in a year, yes?
S: Yes.
通过PPT重复呈现两组春夏秋冬的图片，并在4张图片的中间标出“seasn”一词。
T: Hw many seasns are there in a year, bys and girls?
S: Fur (在此环节，学生肯定会简单回答fur，教师要引导学生将句子补充完整There are fur，并纠正学生th和There are的发音) .
设计意图：通过展示四季图片，观看韵文的形式，让学生直观理解seasn的含义，理解和掌握本单元的核心词汇。
新授
1．Listen and say
（1）PPT出示第一幅主题图，引导学生仔细观察图片，并提出问题：
①What can yu see in the picture? (I see Lala/ Kate/a sheep….)
②Hw many sheep are there? (There are five.)
③Can yu guess what’s Lala saying?
以师生问答的形式，来引导学生了解对话背景，猜测对话内容。如果学生对第③个问题的猜测是正确的，播放录音核对答案；如果学生猜不出Lala会说些什么，播放录音后再让学生回答这个问题。
（2）听录音，理解对话。
听第一遍对话，回答：
①What’s Lala saying? (Hw many seasns are there in a year? 学生回答后，播放录音，请学生跟读模仿)
②Hw many seasns are there in a year? (There are fur.)
板书：Hw many seasns are there in a year?
There are fur.
听第二遍对话（listen, watch and repeat），回答：
There are fur seasns in a year, what are they? (They are spring, summer, autumn, and winter.)
PPT出示小羊手中的4幅图片，请学生认读spring, summer, autumn, winter四个单词；然后将seasn, spring, summer, autumn, winter五个单词贴在黑板上，随机指读。
（3）听录音跟读模仿，重点跟读There are fur，They are spring, summer, autumn, and winter，区分There are与they are的发音。
（4）练习对话，由教师、男生、女生分角色表演对话。
（5）拓展练习。
T: There are fur seasns in a year, they are spring, summer, autumn, and winter. Which seasn d yu like? D yu like summer? D yu like autumn? Next, let’s enjy a chant.
Summer is ht, we have n schl.

T: Yu like …, because …, yes?

（6）听录音，理解对话，回答问题。
播放第一遍录音，请学生回答：
①Which seasn des Lala like? Lala likes spring, summer, autumn r winter? (Lala likes summer.)
②Hw abut Kate? (Kate likes winter.)
听第二遍录音，跟读并回答：
①Why des Lala like summer?(Because the sky is blue. The grass and leaves are green. )
②Why des Lala like winter? (Because Kate likes the white snw.)
答句对于学生来说不是太好理解，教师可出示图片辅助学生理解；同时将blue, green, white这三个表示颜色的单词在图片中呈现出来，帮助学生更好理解句子。
（7）打开课本，逐句播放录音，让学生跟读。
（8）同伴练习对话，分角色朗读对话。
2．Rle play
（1）小组内练习两组对话。
（2）请学生戴着头饰进行角色扮演。学生可在两组对话之间任选一个进行表演。教师要及时纠正学生的语音、语调，注意there are、they are的发音，并对完成较好的小组进行奖励。
