The Greatest Invention In My EyesGood evening,ladies and gentlemen.Last night in my room,busy preparing for my speech today,I was puzzled at the opinions of greatest inventions of different persons.I read many books.Some articles hold the opinions that the greatest invention in the world is electricity,while the others believe computers cannot be replaced in the modern society.I read and read,suddenly an idea struck me:The greatest invention are just books.A famous person has ever said:"Books are the best teachers." Exactly!That's what I would like to say firstly.In the long history of human being,books have played an important part in communicating knowledge.And even today,the situation is still so.Each year,millions of books are published in the world.Knowledge changes our lives.
