Who was Edison? Do you know how many inventions he made? Can you mention some of them? Everybody knows he invented the electric bulb. A lamp can’t give light without electricity. Thomas Edison invented the electric bulb.Did Edison invent electricity? Can electricity be invented? Is electricity an invention or discovery? Why? 2. Which of this pictures show inventions? Does any of them show discoverers?Stephenson’s “Rocket”DNA伽利略的望远镜牛顿制造的反射望远镜X射线广泛用于医学领域谷腾堡发明的印刷机英国钟表匠阿克莱特发明的水力纺纱机3. Work out rules that will help you decide what is discovery and what is an invention?(1) A discovery is
A discovery merely makes known something that already exist in nature, such as the discovery on the New Continent by Columbia. (2) An invention is
something that created by human being, such as the lighting rod. 4. In pairs discuss any modern inventions you know. Describe them to your partner and explain how they changed people’s lives.1. Electricity1. Systems of delivering electrical light and heating to homes and offices
2. Household machines for washing, ironing, keeping food cold, etc
3. Computers, telephones, television, etc2. The movement of air1. Airplane jet engines
2. Air balloons, etc Machines to help people with serious disease (like kidney failure) 3. The circulation of the blood4. X-raysBody scanners to see whether you are ill
2. Machines to treat illnesses (like cancer) Do you know the stages every inventor must go through before they can have their invention approved? Inventing is a scientific activity and so follows similar stages to those used in research. Work out a suitable order.Pre-reading Applying for a patent
2. Finding a problem
3. Doing research
4. Testing the solution
5. Thinking of a creative solution
6. Deciding on the invention As you read the following passage, check the order you wrote above to see whether it follows the correct stages in producing an invention.ReadingFind a problemThe snakes must be removed but not harmedDo researchLook for methods of removal; the habits of snakesI.

active. So extra cooling to the snake
would make them even less active and
easier to catch. The text narrates the problem of the snakes and presents the procedures of catching them and applying for a patent, from which we have got a better understanding of how to do scientific researches and how to apply for a5). What’s the main idea of the text?patent. After learning, we know that it usually costs some time and continuous efforts in order to solve some practical problems in a scientific way. The writer wants to inform us of the scientific methods to solve present problem so that we students can not only broaden the horizons but become more skilled in discovering and considering carefully the problems in daily life. 6).
