九年级英语语法复习：现在完成时态语法复习学情分析： 现在完成时是初中复习的重点，在九年级教学中发现很多学生对现在完成时遗忘较多。自在八年级下册第九单元学习后，尽管在九年级教学中只有第二单元略有涉及，第十单元的过去完成时与之有些关联，但学生运用较少又没有系统复习遗忘较多。学生容易将现在完成时态与一般过去时混淆。因此教师以一些生活中的例子为主题展开教学。一Teaching aims1.Develop students speaking ability2. Students can master the basic structure of the simple past tense and how to judge the simple past tense.3. Students can master the basic structure of the present perfect tense and how to judge the present perfect tense.4. Students can correctly distinguish the usage of have been/gone to and have been in 5. Students are able to convert the transient verbs and the continuity verbs correctly.二、Key and difficult points1. Students can master the basic structure of the simple past tense and how to judge the simple past tense.2. Students can master the basic structure of the present perfect tense and how to judge the present perfect tense.3. Students are able to convert the transient verbs and the continuity verbs correctly.三、Teaching Aids Multi-media,四、Teaching proceduresStep1：Revision 复习过去分词和过去分词的几种结构。Step2:Lead-in 以教师小时候的学习生活经历和学生的学习生活经历比较，尽可能多地使用过去式、过去分词形式不同的动词，在师生、学生的对话中实现对现在完成时的肯定句、否定句和一般疑问句的使用，及第一、第二人称与第三人称之间的转换，同时通过师生对话，让学生感知一般过去时与现在完成时的不同用法。此环节中重点复习现在完成时用法的第一种主要用法“过去发生的动作对现在存在影响或结果”。例如教师呈现图片跟学生交流： I walked 10 kilometers to school. Have you ever walked so 10 kilometers to school? 然后让学生问另一学生Have you ever walked to school？再让学生转述 He/ She has / hasnt walked to school. 在此环节中设置的语言情景载体尽可能让学生有机会使用规则和不规则动词如pick/ picked/ picked, produce/ produced/produced, play/played/played, carry/carried, build/build/built, ride/rode/ ridden, see/ saw/seen, make/ made/made等。此环节的设定目的是为了让学生对沉睡已久的现在完成时提供一个记忆的复苏过程。最后以学生间的pair work进行巩固运用。Step3：Practice 让学生总结一般现在时和现在完成时的区别。Step4：practice 让学生总结动词过去时、过去分词的变化规则并进行巩固练习。设置的练习内容与前面对情景相对应。Step5：Learning 通过谈论一些生活中的各种例句复习现在完成时的第二种主要用法“过去发生的动作一直延续到现在或将来”。Step5：Summary 在练习中强化现在完成时不同句式的变化、短暂性动词延续性动词的转换 since/ for，have been to/ have gone to用法的区分。Step6：让学生以英语俱乐部成员的身分，写信告诉好友刚刚结束的圣诞聚会。通过写作，让学生在文章章中进一步巩固运用现在完成时。Step6:HomeworkFill in the blanks with the proper form.1.
