3. Listen to a radio interview with Dr Han and Vincent Black giving their predictions about the future, and then fill the table below.

Dr Han（男1）: Certainly. I'm a computer scientist.

Host:And could you please tell us your prediction?

Dr Han: Yes, well, I forecast that computers will be cleverer than us in the future. I think that people will also be programming computers to think like humans.

For example, I think scientists will put some small intelligent machines, called nanobots, inside our bodies to increase our abilities.

Host: Wow! That would make each one of us superhuman! And Vincent, could you please tell us about your job?

Vincent Black（男2）: Certainly. I’m an architect. I design buildings.

Host: And what is your prediction about the buildings of the future?

Vincent Black: It's about the cities of the future, actually. I believe that cities floating on water are part of the world's future.

Host: Oh, really? What might make us want to do that?

Vincent Black: Yes. With global warming causing polar ice to melt, the sea level rising by many metres is a very realistic prospect. Instead of moving people away from the sea, I think that people could move into housing in cities that float.

Host:That sounds very innovative. Could you please give us more details?

Vincent Black: Sure. Well, I’ve developed a plan by designing a city that borrows many ideas from the giant water lily, a flower that floats on water. Moreover…
