There are many computers in it. There was no computer room in his school. There were no computers, either.4Grandpa 作为guest来到Wu Yifan 的学校，一起来听听“What are they talking about?”。教师播放Let's talk录音，学生思考问题，并做出判断：There was a library in Grandpa's old school. (×)There was only one small building on a hill. ()He couldn't see stars at night. (×)There are computers now. ()5学生自学对话，并回答“What was Grandpa's school like?”，学生分小组讨论，然后全班汇报。全班讨论时，结合上下文帮助学生理解单词star、easy、Internet和句型“How do you know that?”“Tell us about your school, please.”。6教师播放录音，学生跟读，然后分小组读。Step 3：Consolidation&Extension(巩固&拓展)1学生分角色表演对话，请几组上台表演，教师予以指导。2替换其中的关键词，如library、computer等，重新编写对话，并表演对话。3指导学生完成书上Draw and talk的练习。要求学生画出自己五年前的学校以及现在的学校，并向组员一一介绍变化，运用句型“There was/were.”“There is/are.”来对比描述，其他成员评价、纠正并学习。Step 4：Summary(小结)本课我们重点学习了Wu Yifan爷爷参观学校，对比学校的以前和现在，学习词汇star、easy、look up和Internet，学习运用句型“There was (no).”“There were.”谈论学校的过去。Step 5：Test(当堂微测)用所给词的适当形式填空。1There _(is) no library in my old school.2Could you see _(star) at night?3The Americans _(take) about five days to get there in 1969.4I _(look) it up on the Internet.5There _(are) no computers or Internet in my time.
