牛津译林版八年级英语下册8BUnit3第5课时教学设计(无答案)

牛津译林版八年级英语下册 unit3 Grammar 1 【自学探究】 一、预习 P47—P48，词组翻译。、 1．重新启动电脑 2．双击 3．把电线和电话机联系起来 4．出现在屏幕上 5．按命令键 二、完成课本 P48 的相关练习。 三、被动语态 A 英语中的动词有主动和被动两种语态。主动语态表示主语是动作的执行者。被动语态表示主 语是动作的承受者。 1.基本结构：主语+助动词 be +及物动词的过去分词 例：The company makes this kind of TV set. 这家公司制造这种电视机。 This kind of TV set is made in that company. 这种电视机由这家公司制造。 （this kind of TV set 是 make 这个动作的承受者，所以要用被动语态 be made ）。要指出动 作的执行者，可用“介词 by+动作的执行者”结构。 例如：This letter was written by my brother. 这封信是我弟弟写的。 2.其他句式变化： 否定句：This kind of TV set is not made in that company. 这种电视机不是由那家公司生产的。 一般疑问句：Is this kind of TV set made in that company? 这种电视机由这家公司制造的吗？ 特殊疑问句：Where is this kind of TV set made? 这种电视机由哪里制造的？ 3.什么情况下用被动语态： 1).不清楚动作执行者是谁时； 例如：His bike has been stolen.他的自行车被偷了。 （不知道也没有办法知道是谁干的） 2).没有必要或不想说出动作执行者时； 例如：Rice is grown well there. 那里的稻子长得很好。 3).强调动作的承受者时； 例如：This book has been sold out, but that one hasn’t. 这种书卖光了，那种没卖光。 3.及物动词能构成被动语态，不及物动词不能构成被动语态。只有这些不及物动词与介词或 副词构成不可分割的短语，并且带有宾语时，才可用被动语态。 例如：The old man is looked after very well in the hospital. 那老人在医院受到很好的照看。 4.有些动词带有双宾语，变成被动语态时，两个宾语都可以作被动语态句中的主语，但间接 宾语作主语的较多。 例如：He gives me one yuan a day. 他每天给我一块钱。 I am given one yuan a day. One yuan is given to me a day. 5.有些动词后接不定式作宾语原可省“to” 的，变成被动语态时要加上“to”。 例如：The teacher often makes us read English aloud in the morning. 老师常要我们早上大声朗读英语。 We are often made to read English aloud in the morning(by the teacher). 【教案】 课题 8BUnit 3 Grammar(1) 课型 新授课 教学目标 1、理解被动语态的概念； 2、了解被动语态的基本结构；学会正确使用被动语态。 重难点分 析 理解并学会使用被动语态 学情分析 学生已经大体了解被动语态，但如何正确表达却有一些茫然，所以要通过情景训 练教给他们具体用法。 教学方法 情景教学法,归纳法 教具准备 课件 教学步骤 教师活动 学生活动 个性化补充 Step 1 Lead-in 1.Talk about the different parts of the computer and their usage. 2.
