(you are giving us a lesson.) 請學生嘗試翻譯這句話的意思。同樣把句子寫在黑板上，并把時態(tài)部分畫出來。2 告訴學生：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”. 把這個結(jié)構(gòu)寫在黑板上，請學生就剛才的四句話說說看，具體哪部分是時態(tài)的結(jié)構(gòu)。3 教師對一個學生說：s1, please stand up. 然后問其他學生：what is s1 doing? (she /he is standing.)教師再用close the window，clean the blackboard，write a letter，carry the desk等動作指令做如上演示，使學生充分體會現(xiàn)在進行時的情境。step ii 呈現(xiàn)1 教師板書：he is standing. 并說：if i want to change “it” into “they”, what will happen to the sentence? 教師將they寫在he下面，請一位學生說說句子將如何變化。引導(dǎo)學生發(fā)現(xiàn)主語變化引起的be動詞的變化，幫助學生說出：they are standing. 以此方法分別變換主語為i，she，we，you，tom，all the class等， 幫助學生意識到be動詞的使用受主語影響。完成98頁的“work out the rule!”2 再回到黑板上“he is standing”這個句子。引導(dǎo)學生發(fā)現(xiàn)“be+ doing”的結(jié)構(gòu)里doing= do+ ing ，然后在standing下面寫上speak，請學生說出speak加ing的形式和讀音。3 再板書have，問學生怎么加ing，在幫助學生寫出having后，再給出give，make，take，請學生將他們的ing形式寫出來，并請學生寫出規(guī)律。幫助學生正確表述這一變化：以不發(fā)音e結(jié)尾的單詞，要去掉e，再加上ing。以此方法總結(jié)歸納出加ing的另外兩條規(guī)則。4 進入第97頁講解時態(tài)的表格，進一步為學生總結(jié)講解規(guī)則，告訴學生可以在動詞to be后面加上not來構(gòu)成否定結(jié)構(gòu)。step iii 練習1請學生兩人一組討論完成a部分的練習。核對答案，請學生將題目逐一讀出來，教師將有特殊變化的動詞寫在黑板上，然后全班集體將句子讀一遍。2 利用a部分的練習，檢查學生對現(xiàn)在進行時肯定結(jié)構(gòu)的理解。4教師給出一些表示動作的圖片，請學生兩人一組用現(xiàn)在進行時態(tài)對話：here are some pictures. please talk about what they are doing with your partner. 教師請一位學生配合先進行示范。sample conversationt: what are the children doing?s: they are having lunch.t: what are the women doing?s: they are shopping.給學生三分鐘時間準備，然后請幾組不同層次的學生對話。step v 呈現(xiàn)1 教師就剛才活動中的某一幅圖片問：are they having lunch? 幫助學生回答：yes, they are. 再利用另外一幅圖片引出否定回答：no, they arent.2 請學生閱讀98頁相關(guān)表格，和學生一起學習規(guī)律：to be放到句首即構(gòu)成現(xiàn)在進行時的一般疑問句，其肯定與否定回答與to be的一般現(xiàn)在時疑問句的肯定與否定回答相同。3 仍然利用剛才的圖片開展下面的操練活動。sample conversationt: are the women shopping?s: yes, they are.t: is the t
