Last weekend教学设计详案
上传: 成文辉 &&&&更新时间： 21:20:04
教学目标：
1）认知目标：能够听、说、读、写短语watched tv、washed the clothes、cleaned the room、played football、visited grandparents,掌握规则动词一般过去式的构成;同时，能听懂问句what did you do last weekend？并做出正确回答;能运用所学语言知识并结合自己实际谈论自己的周末活动。
2）能力目标：能够用一般过去时描述自己在过去时间里所做的事情。
3）情感目标：通过本课语言知识的学习,教育学生多熟悉身边的人所做的事情,并能做到经常关心他人。
教学重难点：
1）重点:听说读写短语watched tv、washed& clothes、cleaned the room、played football、visited grandparents；能听说句子what did you do last weekend？并能就过去时间所做的事情进行简单回答或者描述他人过去所做的事情。
2）难点：学生对本课的几个短语都比较熟悉，但动词的过去式第一次出现，因此，这几个短语的动词过去式的构成及其发音是本课时的难点。教学过程中可以通过相互比较、强化操练来突破此难点。
教学准备：自制单词卡片和多媒体课件
