A handsome young man is enjoying VR and a robot is standing on the beach. Now let’s go through Bill Gates’ words under the topic “Living with technology”. It reads “The advance of technology is based on making it fit in so that you don’t really even notice it, so it’s part of everyday life.” What does it mean?T: Right.

You have known something about the topic of the unit: How technology is woven into our life.2. T Now watch a video carefully and fill in the blanks. T: Watch the video again and answer the three questions on page 43. Answer 1 the moon, computersAnswers 2 1. In the popular science fiction TV series, Star Trek, the people in the future use a device called a “communicator”, which looks similar to the cell phones of today. 2. Yes, I agree with Jules Verne’s statement. Looking around today, many things that people in the past believed could never happen have become a part of our daily lives. No, I don’t agree with Jules Verne’s statement because even though humans may feel capable of achieving the impossible, there are some dreams that are beyond our capabilities. 3. In the future, I think our hands will be implanted with sensors to become scanners themselves. Using our hands as scanners would make it more convenient to identify ourselves and pay for items. Our hands could even be used to exchange digital business cards or any other information through a handshake. Sophisticated scanners with sensors created for professionals, such as a doctor’s hand, would mean a patient could be diagnosed in an easier way.【设计意图：由43页上的图片、Bill Gates的话以及译林所提供的短视频让学生对本单元主题有个概念，并引发学生的对本单元学习的兴趣。
