step 1
t: look at the teachers’ desk. i have many things on it. now i’m a shop assistant. who’d like to buy something from me?
s: may i have a …?
  may i have a … for xxx?
t: yes/ sure, here you are.
  yes, this … is for you.
s: thank you. goodbye!
t: goodbye!/ see you!
step 2
t: ( after several groups) oh, i’d like to buy some useful things, too. who’d like to be the shop assistant? (ask one student to have a try)
s1: good morning! can i help you?
t: may i have this storybook?
s1: sure, here you are.
t: may i have that pen?
s1: ok, this pen is for you.
t: thank you. bye!
s1: see you!
t: ( put the storybook and pen in the bag) oh, you’re a kind and nice shop assistant. you’ve done a good job! boys and girls, let’s reward her a star!
s: shining!( action)
ask some more students to have a try. ( s-t   s-s )
step 3
t: now please look at the blackboard and i’ll write down the new sentences. look carefully and do you have any questions? are they right or wrong? (point to the title when i say these words.) you can speak in chinese this time.
    may i have this storybook
may i have that pen
s2: miss wang以前讲过书写句子时：句首字母要大写，句子末尾要标点。这句话的末尾少了标点符号。
t: yes, you are right. (给句子添上标点)
  may i have this storybook.
may i have that pen.
are they right now?
s3: no, miss wang这句句子是问句，不能加句号，应该在句尾加问号。
t: yes. (把句号改成问号) any questions now?
  may i have this storybook？
may i have that pen？
s4: miss wang,你还讲过句子是由单词组成的，而单词是由小写字母组成，因此组成句子的字母都是小写字母。但这句话里的“i”是大写字母，应该改成小写“i”。
t: yes. but today i’ll teach you a new rule, that is, “i” am the most important one in the world, so it must be capitalized for ever. (“我”永远要大写。)please remember this rule by your heart. understand?
s: yes.
step 4
t: now please use the new drills to buy things from your partners.
after several minutes, ask some students to act out their dialogues.
t: ok, let’s have a break and say the chant “ a little book”.

反思：
学习英语新课程标准已经有一段日子了。在分析本课教学内容时，我觉得本课中英语句子的书写（包括陈述句和疑问句）这一内容十分适合让学生去自主探究学习。针对这一内容，我决定采用“故谬法”来进行疑问句书写方法的教学。通过设计一项探究性的学习活动，要求学生利用自身已有的知识或信息（英语陈述句的书写方法），通过观察、发现、讨论、归纳、运用等方法主动获取新知识或信息、，学习新的语法知识（英语疑问句的正确书写）。让学生在“发现错误——找到原因——改正错误”的过程中学会如何正确书写疑问句。一堂课下来，发现不仅原来枯燥乏味的书写教学变得生动、有趣了，而且更重要的是，学生在主动探究的过程中已牢固掌握了疑问句的书写这一教学难点，有效的提高了课堂的学习效率和学习效果。
