Unit4 At the farmA .Lets talk & Lets play一、课时分析 本课时是（pep）小学英语教科书四年级下册的第四单元第一课时，本课时围绕“参观农场”这个话题展开内容，主要包括 A.Lets talk & A. Lets play 两个板块。本课时的A Lets talk .部分通过Mike 与Sarah 参加农场并与农场主人对话的情景让学生感知句型：Are these carrots? Yes, they are. No, they arent. 以及What are these? Theyre tomatoes.的语义及语用情景。A Lets play 部分则是用来操练A Lets talk板块的核心句型。本课时核心句型是涉及名词复数形式的特殊疑问句和一般疑问句，这一知识点在四年级上册第四单元的B Lets talk 出现过一次，本册学生用书的前三单元均未有涉及。教师可创设适当的语境让学生充分的感受并理解名词单、复数的意义以及相应句型变化，并能在情景中正确运用和表达。 二、课时目标1. 能够在情景中运用句型：Are these ? Yes, they are. No, they arent. 以及What are these? Theyre .询问物品名称并回答。 2. 能够在情境中恰当运用句型They re good/ so big!描述物品的特点。 3. 能够在语境中理解新词carrots 和 tomatoes 的意思，并能正确发音。 4. 理解A Lets talk .部分对话大意，能够用正确的语音语调朗读对话。三、课时重难点1. 课时重点能听、说、认、读本课时的主要句型：Are these ? Yes, they are. No, they arent. 以及What are these? Theyre .并能做出正确的回答。2. 课时难点 Are these 后面跟的是名词的复数形式。四、教学准备 1. 单词卡片 2. 教学挂图及配套PPT 3. 录音机及配套磁带 五、教学过程Step 1 Warm up1.greetings T: Good morning, everyone.
