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。三、课时目标1. 能够在情景中运用句型：Are these ?
