It has been predicted that mobile phones might soon replace our wallets. For example, instead of handing over cash to pay for groceries, our mobile phones would be scanned and the cost added to our next phone bill. The idea that in the future we wont need to carry money seems crazy, but 80 years ago, the idea that you could walk out of your house with your phone in your hand probably seemed crazier! Mobile phones have become a major part of our lives and one wonders what the next technological advance will be.(2) ReadingHannah Jones looks into the future of futurology.I love talking about the future - and I am not the only one. Over the centuries, people have always wondered about the future. Some like to read fantasy stories and imagine what the world will be like in 10, 50 or even 1000 years time. Others foresee future opportunities and problems. They plan the future of the world for a living. These people are called futurologists.This weekend, hundreds of futurologists are meeting at Newcastle University. The seminar starts on Friday and the experts will be discussing the influence of technology on the future. The future is now big business. I clicked into the websites of some futurologists and heres what theyre predicting:The technology already exists, so very soon all of us are going to use our voices to give instructions to computers. In the next few years, we will be communicating with our friends around the world using life-sized video screens in our living rooms.By the year 2020, computers will already have become more handy and also more powerful than the human brain both in terms of intelligence and the amount of information they can store.By the year 2030, development in biochemistry and medical science will make it theoretically possible for us to live for at least 150 years. Tiny, insect-like robots may be sent around our bodies to carry out repairs and keep us healthy.By the middle of the century, computers that are millions of times smarter than us will have been developed. We will be linking our brains to these computers and a huge database. A new species might have developed!By the end of the century, we will have discovered other places in our solar system suitable for living and will have discovered ways to go further into space.Ill be there in Newcastle this weekend. At nine oclock on Saturday morning, Ill be sitting in the front row and listening to the great Duke Willard talking about the future of my brain. If you cant beat the future, join it!(3) Post-readinga) The Programme of the futurologists conference Friday4-5:30 p.mProf. Howard Green: Alternative Sources of Energy-New Concept6-7:30 p.mGroup discussion: Love and Friendship in the 21st century 8 p.mReceptionSaturday9-11:30 a.mProf. Duck Willard: The Future of the Human Brain12-1:30 p.mDr.B.A. Lorry: Vehicles of the Future2-3:30 p.mLunch4-5:30 p.mProf. Stella Spacek: Exploration of Mars and Venus6-7:30 p.mDr. D.N.A.

At a depth of 200m below the sea, there is still about 1.5% dissolved air. Fish gills work comfortably with this amount of air, and now Israeli inventor Alon Bodner has designed a way for man to do the same, eliminating the need for cumbersome oxygen tanks and expensive air compression units. If it goes to plan, a tankless underwater breathing system in the form of a vest that will be attached to a diver should be available in a few years time.(4) Homeworka) Match the vocabulary with the explanations. 1)wonder about a. estimate in advance 2)foresee b. survive or continue living with difficulty 3)meet c. go into a website 4)seminar
