of Francis Crick and James Watson and published in 1953.These two scientists 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 2023,which discovered the Structure of DNA.,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 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 invention,Pre-reading II(3m),The suitable order:,Finding a problem,Doing research,Thinking of a creative solution,Testing the solution,Deciding

protected.,patents,Reading,The problem of the snakes,Skim the whole passage and get the main idea:,The text narrates _ and presents _,and applying for _.,the problem of the snakes,the procedures of catching them,a patent,Reading-I(3m),Divide the text into four parts and work out the main idea for each paragraph.,Part I,Part II,Part III,Part IV,(Para.1),The discovery of the problem of the snakes.,(Paras2-3),The research on the approaches to solve the problem.,(Para.4-6),The attempts to catch the snakes.,(Para.7-8),The requirement of getting a patent.,Reading II(5m),Scanning:Find out which paragraph or paragraphs deal with each inventing process in the passage and find the examples:,paragraph,Stages,Examples in this story,Find a problem,The snake must be _but not_,Do research,Look for _ of removal;the _ of snakes,Think of a creative solution,Identify _ possible approaches:choose_.,removed,harmed,methods,habits,three,one,1,2,3,Reading III(7m),Test the solution several times,Try_ times to make it work_,Apply for a patent,4,5,6,7,three,efficiently,Fill in the form and filed patent application with the Paten Office,Detailed reading:,Answer the following questions:,What was the mother upset about?,Why was the writer happy to help her mother?,What are the three creative steps that the writer takes to catch the snakes without hurting them?,Why did cooling make the snakes less active?+,Discuss with your partner what the advantages might be of getting a patent.,Reading IV(5m),What was the mother upset about?,2.Why was the writer happy to help her mother?,The mother was upset because a family of snakes had made their home near the house.,The writer was happy because it gave her an opportunity to help her mother and invent something to catch the snakes without hurting them
