and
Mike
are
also
at
Uncle
Sam’s

They
are
not
( http: / / www.21cnjy.com )sure
about

a
question,
too.
Let’s
listen,
watch
and
find
out.
学生找到两个问题：
Are
these
carrots
What
are
these
根据学生的回答，句中问号变为具体的问题句子。
第一句：出示词卡教读；师板书：

（将词卡贴到词附近）然后指导朗读问句。注意语音语调的朗读指导。
第二句：指导these的朗读。
2、提出问题，第二次视听课文内容

师补充
Why
doesn’t
Mike
know
the
tomatoes
Because
they’re

So
Mike
says:
“But
they’re

教材分析
四年级下册第四单元学习的主题是farm
( http: / / www.21cnjy.com )。本单元通过农场里各种动物以及农作物的学习，从而展现了农场中缤纷多彩的生活。虽然与学生的实际生活相隔甚远，但其内容与学生的日常生活联系紧密。因此要求学生能用本单元的句型与单词进行有关农场里各种动物和各种农作物的表达。
本节课是第四单元的第一课时，是一节对话课
( http: / / www.21cnjy.com )。它是一段小朋友和农场叔叔之间的对话，展现了小朋友们到农场参观，对很多事物都感到新鲜和好奇的场景，同时也激发起课堂上学生的兴趣。本课时所学内容是我们日常生活所吃的蔬菜。主要语言结构为：What
are
these /Are
these...
Yes,they
are./No,
they
aren’t.以及相关单词：tomato，
green
bean,
potato,
carrot通过本节课的学习，学生基本能用：What
are
these
They’re....
Are
they...
Yes,
they
are
./
No,
they
aren’t.等句型询问复数。为下一个课时学习作铺垫。
本课时的两部分内容都是通过情景对话来完成的，
( http: / / www.21cnjy.com )教师应积极鼓励每一个学生参与对话，为学生创造更多的语言训练机会。在学生积极参与表演对话时，不要求学生都必须按照课文内容表演，可根据实际情况或对基础较好的同学，鼓励他们用学过的相应词汇进行替换，如：几个同学表演第一个对话时，学生就可以将对话中的carrots替换成pens,
rulers等，学生更容易进行真实的交流。为了便于学生更加熟悉两个句型的使用，教师应当在课文的基础上有目的得多设计一些交际活动，如：Ask
and
answer等，为学生提供更广阔的交际空间。PEP

2.

（二）
寻找农场主：听录音判断农场归属
三、课后练习：
设计自己的农场，并根据农场内动、植物创编自己team的对话，下节课展示。
(设计意图:将课文对话的拓展作为本课课后作业，便于教师检查每一位学生是否掌握本课知识，语音语调是否地道正确。)评测练习：在
教学过程中我采用口头
( http: / / www.21cnjy.com / )评价的方式，在学生回答问题教好或者是有创新性的问题时，我采用口头表扬的方式给予肯定，在练习方面：我采用了猜、读、写的方式。让学生根据拼读规则猜单词，在听的基础上确认单词读音，在呈现相关的练习题进行巩固和检测。
