文档简介
课件81张PPT。Unit 3 Inventors and inventions Here are some of the most popular inventions according to a survey among our readers：
1．The Telephone
The telephone is an instrument that convertsvoice and sound signals into electrical impulses and send them to a different location by wire, where another telephone receives the electrical impulses and turns them back into recognizable
sounds. In 1875, Alexander Graham Bell built the first telephone that transmitted electrically the human voice.
2．The Computer
Here are many major milestones in the history of computers, starting in 1936, when Konrad Zuse built the first freely programmable computer.
3．The Automobile
In 1769, the very first self-propelled road vehicle was invented by French mechanic, Nicolas Joseph Cugnot. However, it was a steam-powered model. In 1885，Karl Benzdesigned and built the world's first practical automobile to be powered by an internal-combustion engine(内燃机). In 1885 , Gottlieb Daimler took the internal-combustion engine a step further and patented what is generally recognized as the prototype of the modern gas engine and later built the world's first four-wheeled motor vehicle.
4．The Steam Engine
Thomas Savery was an English military engineer and inventor who, in 1698, patented the first crude steam engine. Thomas Newcomen invented the atmospheric steam engine in 1712. JamesWatt improved Newcomen's design and invented① what is considered the first modern steam engine in 1765.
5．The Light Bulb
②Contrary to the popular belief, Thomas Alva Edison didn't “invent” the light bulb，but rather he improved upon a 50-year-old idea.In 1878，Sir Joseph Wilson Swan, an English physicist，was③ the first person to invent a practical and longer-lasting electric light bulb (13.5 hours)with a carbon fiber filament.
