(you are giving us a lesson.) 请学生尝试翻译这句话的意思。同样把句子写在黑板上，并把时态部分画出来。2 告诉学生：when we want to talk about things that are happening now, we should use this tense - the present continuous tense. its structure is “be+ doing”. 把这个结构写在黑板上，请学生就刚才的四句话说说看，具体哪部分是时态的结构。3 教师对一个学生说：s1, please stand up. 然后问其他学生：what is s1 doing? (she /he is standing.)教师再用close the window，clean the blackboard，write a letter，carry the desk等动作指令做如上演示，使学生充分体会现在进行时的情境。step ii 呈现1 教师板书：he is standing. 并说：if i want to change “it” into “they”, what will happen to the sentence? 教师将they写在he下面，请一位学生说说句子将如何变化。引导学生发现主语变化引起的be动词的变化，帮助学生说出：they are standing. 以此方法分别变换主语为i，she，we，you，tom，all the class等， 帮助学生意识到be动词的使用受主语影响。完成98页的“work out the rule!”2 再回到黑板上“he is standing”这个句子。引导学生发现“be+ doing”的结构里doing= do+ ing ，然后在standing下面写上speak，请学生说出speak加ing的形式和读音。3 再板书have，问学生怎么加ing，在帮助学生写出having后，再给出give，make，take，请学生将他们的ing形式写出来，并请学生写出规律。帮助学生正确表述这一变化：以不发音e结尾的单词，要去掉e，再加上ing。以此方法总结归纳出加ing的另外两条规则。4 进入第97页讲解时态的表格，进一步为学生总结讲解规则，告诉学生可以在动词to be后面加上not来构成否定结构。step iii 练习1请学生两人一组讨论完成a部分的练习。核对答案，请学生将题目逐一读出来，教师将有特殊变化的动词写在黑板上，然后全班集体将句子读一遍。2 利用a部分的练习，检查学生对现在进行时肯定结构的理解。4教师给出一些表示动作的图片，请学生两人一组用现在进行时态对话：here are some pictures. please talk about what they are doing with your partner. 教师请一位学生配合先进行示范。sample conversationt: what are the children doing?s: they are having lunch.t: what are the women doing?s: they are shopping.给学生三分钟时间准备，然后请几组不同层次的学生对话。step v 呈现1 教师就刚才活动中的某一幅图片问：are they having lunch? 帮助学生回答：yes, they are. 再利用另外一幅图片引出否定回答：no, they arent.2 请学生阅读98页相关表格，和学生一起学习规律：to be放到句首即构成现在进行时的一般疑问句，其肯定与否定回答与to be的一般现在时疑问句的肯定与否定回答相同。3 仍然利用刚才的图片开展下面的操练活动。sample conversationt: are the women shopping?s: yes, they are.t: is the t
