Step1：Greetings and leading-in

Activity1: Guessing game (1’)

Let students guess the topic by showing  several attractive pictures.

Step2: Pre-reading

Activity2: Preparing and sharing（Individual  and Group work / 9’）

1、教师提供符合学生阅读的各种相关信内容涉及对未来计算机的设想的文章。

2、学生六人一组，向其他组学生介绍自己总结的文章内容即描述未来计算机（6min）；

[设计思路]本活动旨在让学生通过自己对已有信息的主动加工和组织来了解和分享计算机的背景知识。该设计教师不再是背景呈现者，而是资源库的提供者。活动涉及主要有interpersonal和interpretative两类常用的交流模式，且信息均来源自现实生活。本设计体现了学生为中心，教师为指导的思想。

Step3: While-reading

Activity3: Read the passage and finish the  timeline below (individual work / 3’）

1642 :  _________________________________________

____ :_________________________________________

1940s:  ________________________________________

____ : The first family of computers was  connected to each other.

1970s:_________________________________________

Now :  _________________________________________

[设计思路] 本活动属于fast-reading，旨在利用图示理清思路，帮助学生快速获取信息，同时训练学生Skimming的阅读技巧。由于本篇文章由于讲述了计算机的发展历史，故以时间发展顺序作为阅读的线索，可以有效的提高阅读速度和准确率。

Activity 4: Read the passage again and  complete the chart below(pair work /11’)

[设计思路]本活动属于careful-reading，旨在深入理解课文内容。通过此练习来讲解文章的语言知识和篇章结构，锻炼学生寻找Topic  sentence来阅读技巧，并能模仿“topic sentence +supporting details”的写作模式。

Atvivity5:  Translation(4’)

Activity 6:  Ask-and-answer. (Summary / class work /2’)

Q1:What’s main idea  of the passage?

Q2: Do you feel  difficult in understanding the passage? And why?

[设计思路]本活动旨在对文章的内容进行总结，从语言知识到篇章结构知识的判断、分析。通过该活动，学生对本文有了全局的把握。到这里，完成了对课文本身的学习。

Step 4：Conclusion  and homework（2’）

1. Conclusion of  the class

2. Task：“My Robot  Friend----Alice”

Have you ever  chatted with a robot? Do you what to talk with him/her? Now, you have the  chance. You can have Alice, a robot to be your friend. So today, your task is  to meet Alice, talk with her, and then write a 100-word about the talk and  your feeling. Here is the place you can find her. Have a nice talk!

[设计思路] 本活动为学生创设了一个新型的语言学习环境。智能计算机与语篇的拟人手法，在一定程度上都有“人”的感觉，故学生可以进行知识和情感的迁移，该活动能帮助学生利用网络学英语，交好友，形成健康的网络使用习惯。
