《Welcome to the unit》最新教案优质课下载
课堂设计指导思想：
本节课是以听、说、读为主的讨论课。讨论是师生之间、生生之间集思广益、相互启发、相互探讨，实现信息交换，扩大信息和思维容量，以求得解决问题和深化认识的一种方法，有助于学生在掌握一定知识的基础上，提高学习的主动性和分析问题、解决问题的能力。讨论课追求的是主体性、探索性、信息加工的自主性以及学生学习的合作性、交互性和相互启发性。Welcome to the unit是用来介绍本单元主题的，不仅对整个单元有“导入”作用，对Reading的教学更是具有增进知识，提高兴趣，扫除理解障碍的作用。

An old man is celebrating his 200th birthday. It’s amazing that he can live that long.
The aliens and the people are talking about peace issues in the Galaxy or trade affairs between other planets and the Earth.
Step 3 Discussion （PPT page 9，显示讨论问题）
Divide students into groups of four. Ask them to discuss the three questions on page 41. Get students to exchange their opinions in their own groups. Invite several groups to report their responses back to the whole class.
Sample answers
1.Yes, with the development of science and technology, human beings could travel wherever they want in the future. The Moon and other planets could eventually become tourist destinations. Travelling to the Moon or to another planet might be as easy as travelling to another city. You might just have to book a ticket, get packed and think about what present you would like to bring back to your friends on the Earth.
2.In my point of view, robots could do almost everything in the future. With the development of science and technology, they may be designed almost the same as humans. They could help people do boring and dangerous work. For example, it would be possible for robots to be lowered to the ocean floor and left to explore the ocean; robots could play an important role in exploration missions to other planets; they could also be the companions of humans and assist humans physically and psychologically, that is , they could perform more useful functions than just as entertainment.
