1. 用英文介绍爱迪生的一项发明（详细）
Phonograph - History
The first great invention developed by Edison in Menlo Park was the tin foil phonograph.While working to improve the efficiency of a telegraph transmitter,he noted that the tape of the machine gave off a noise resembling spoken words when played at a high speed.This caused him to wonder if he could record a telephone message.He began experimenting with the diaphragm of a telephone receiver by attaching a needle to it.He reasoned that the needle could prick paper tape to record a message.His experiments led him to try a stylus on a tinfoil cylinder,which,to his great surprise,played back the short message he recorded,"Mary had a little lamb."
The word phonograph was the trade name for Edison's device,which played cylinders rather than discs.The machine had two needles:one for recording and one for playback.When you spoke into the mouthpiece,the sound vibrations of your voice would be indented onto the cylinder by the recording needle.This cylinder phonograph was the first machine that could record and reproce sound created a sensation and brought Edison international fame.
August 12,1877,is the date popularly given for Edison's completion of the model for the first phonograph.It is more likely,however,that work on the model was not finished until November or December of that year,since he did not file for the patent until December 24,1877.He toured the country with the tin foil phonograph,and was invited to the White House to demonstrate it to President Rutherford B.Hayes in April 1878.
In 1878,Thomas Edison established the Edison Speaking Phonograph Company to sell the new machine.He suggested other uses for the phonograph,such as:letter writing and dictation,phonographic books for blind people,a family record (recording family members in their own voices),music boxes and toys,clocks that announce the time,and a connection with the telephone so communications could be recorded.

7. 用英语介绍一位发明家
贝尔
Alexander Graham Bell was born in Scotland. His mother, who was deaf, was a musician and a painter of portraits. His father, who taught deaf people how to speak, invented "Visible Speech". This was a code which showed how the tongue, lips, and throat were positioned to make speech sounds. Graham, or "Aleck", as his family called him, was interested in working with the deaf throughout his life.
Thomas Watson became an associate of Bell. He made parts and built models of Bell's inventions. One day while they were working Bell accidently heard the sound of a plucked reed * coming over the telegraph wire. Watson had been tuning the metal reeds in the next room. Bell drew up a plan for the telephone and they continued to experiment. The next day he transmitted the famous words, "Mr. Watson, come here. I want you!" A few months later on Feb. 14, 1876, he applied for a patent on his telephone.
He continued to invent other things. He developed a method of making phonograph * records on a wax disc. He made an iron breathing lung, and a device for locating icebergs at sea. He experimented with sheep. He was interested in kites that could lift a man, and he invented a hydrofoil * which set a world speed record of over 70 miles per hour.
