设计意图：通过提问的方式教学，将学生的注意力引入到本课时的相关内容中去，为后面的正式学习进行预热。
环节2 学习2a－2e
1．分组练习。让学生们分组讨论各自了解的机器人的外形和功能等，然后抽选一两位学生当堂描述他们所知道的机器人。
2．阅读2b的短文，标出其中的生词、重点短语和难句，并将课文上方的四个问题与其相应的段落匹配起来。
3．放一遍录音，学生进行逐句跟读，注意语音语调。然后总结每段的段落大意和文章的主旨大意。老师对短文进行详细讲解，并对同学总结的段落大意和主旨大意进行指正。
4．让学生再次快速阅读一遍短文，完成2c的练习，老师核对答案。
5．让学生浏览2d的短文，掌握其大意，并用2b短文中的单词补全短文。老师核对答案，并对其中的重要知识点进行讲解。
6．让学生课后完成2e的练习，并将优秀的短文在下一个课堂上展示。
7．要点点拨。
(1)Today there are already robots working in factories.
①本句包含固定句型：There is/are sb./sth.doing sth.表示“有某人/某物正在做某事”。
②already adv.已经；早已。它多用于肯定句中，用于疑问句中则表示惊讶或意外之意。
(2)For example，scientist James White thinks that robots will never be able to wake up and know where they are.
①be able to do sth.能够做某事，可用于任何时态。
②wake up醒来，叫醒。它是一个动副型短语，名词作其宾语时可放在up之前或之后，代词作其宾语时，只能放在wake与up之间。
8．学以致用。(用所给词的适当形式填空)
(1)There are many people talking(talk)under the tree.
(2)It's impossible(possible)to finish the work in such a short time.It's too difficult.
(3)Even though you disagree(agree) with Jane，I must say her idea is the best.
(4)There are hundreds(hundred)of students sitting in the hall.
(5)He can do the work better with fewer(few)people and less(little) money.
设计意图：短文之前的讨论帮助学生提高课堂参与的积极性，自然地进入到本课时的学习中来。然后再由整体到部分，由浅入深地学习并理解短文中的重点知识。
