Let some students act out the conversation in front of the class.（设计意图：先输入再输出，符合学生的认知规律。通过生的实际来练习核心句型，真正达到了运用英语的目的。）Step 4: Grammar Focus1. Read the sentences in the chart.方法指导：在读的过程中，注意以Did或Were打头的疑问句，答语有何不同。）2. Ask and answer in pairs.观察与思考1：运用口诀，巧记一般过去时。动词一般过去时，表示过去发生事；be用was或用were，have/has变had;谓语动词过去式，过去时间做标志；一般动词加-ed，若是特殊得硬记。否定句很简单，主语之后didnt添；疑问句也不难，did放在主语前；如果谓语之前有did，谓语动词需还原；动词若是was，were，否定就把not添。观察与思考2：观察下列动词的过去式，试着总结规则动词过去式的变化规律。1. played cleaned wanted needed2. practiced lived danced3. stop- stopped shop-shopped plan-planned4. carry-carried study-studied worry-worried观察与思考3：规则动词过去式词尾-ed的读音（清音）/t/，浊元/d/，t/d/之后读id/)。读音规则读音例词在浊辅音和元音后面/d/moved/mu:vd/在清辅音后面/t/passed /pa:st/在t，d后面/id/needed /ni:did记住下列不规则动词的过去式：go-went come-came get-got ride-rodedo-did is-was are- were have-hadeat-ate buy-bought see-saw（设计意图：采用观察与思考的方式，让学生采用独立思考或小组讨论的方式来总结语言规律，然后通过跟踪训练巩固知识点的用法。这种学生自主学习的方法比单纯的教师解更有效。）Step 5: Practice 3a1. Ask students to read the letters in 3a.2. Ask students to complete Jims letter on the left and Bills reply on the right.3. Check the answers. Ask students to pay attention to the past tense verbs.4.
