4、 that already existed in nature.Look at the pictures below and discuss in pairs which pictures show inventions and which show discoveries.Pre-reading I(4m)An amphibious car(2003)This is the first car that can travel safely on water and on land.When moving on water,the wheels of the car turn sideways
5、 and move into the body.The underneath of the car is strong enough to sail as a boat.It is a prototype and is not yet being produced for sale.This is an interesting modern invention.Stephensons“Rocket”(1781-1848)George Stephenson was one of the first men to design engines for the railways which were
6、 new at that time.One of the first tracks to be laid was between Stockton and Darlington.Stephenson was one of the first railway engineers and in 1825 he drove the first train along the line.The structure of DNAThis was a discovery of Francis Crick and James Watson and published in 1953.These two sc
7、ientists were the first to show that our genes consist of two spirals of DNA(called the double-helix).This work led directly to the human genome project in 2003,which discovered the Structure of DNA.Do you know the stages every inventor must go through before they can have their invention approved?I
8、nventing is a scientific activity and so follows similar stages to those used in scientific research.Look at the list and work out a suitable order.Applying for a patent Finding a problem Doing research Testing the solution Thinking of a creative solution Deciding on the inventionPre-reading II(3m)T

17、s time.When the sun goes down at night they cool down and become less active.So extra cooling to the snake would make them even less active and easier to catch.Match the different writing characteristics with each writing styles:Formal language with few adjectives,not emotional,factualVivid use of w
