One of the most important inventions is the invention of the telephone. The idea behind the telephone is simple. a system which changes sound into a series of electrical impulses of differing frequencies （频率）, and then reverses this procedure to recreate the sound.

As early as 1831, Mickael Faraday proved that vibrations （震动） of metal could be changed into electrical impulses. This was the basic principle of the telephone, but no one made us of such technology until 1861, when German inventor, Johann Reis, successfully built some equipment that changed sound to electricity and back again. The equipment had built some equipment that changed sound to electricity and back again. The equipment had many flaws, unable to transmit many frequencies and therefore was never fully developed.

Two men in the United States Elisa Gray and Alexander Graham Bell （a Scottish inventor）, both worked hard to create what would be known as the telephone almost at the same time, and amazingly both filed for a patent within hours of one another, Bell beating his rival by merely two hours on February 14 th, 1876.

The first comprehensible telephone conversation was said to have taken place between Bell and his assistant, who was sitting in another room. Bell said, “Come here, Watson, I want you”, which Watson successful heard via the receiver and the invention of the telephone was complete. The Bell Telephone Company （AT&T） was soon established and grew to be the largest telephone company in existence.

The following year, in 1877, the first telephone system was put in place in Hartford, Connecticut, while the first exchange linking two cities was established between Boston and New York in 1883. London hosted the first exchange put into practice outside the US in 1879.

The invention of the telephone is a hot topic within the inventor circle. Many believe it to be Alexander Grabam Bell, while others believe it to be Antonio Meucci, Philip Reis, or Elisha Gray.

　　　Can you imagine(想象)what life would be 　21　if there were no telephone? You could not call on your friends on the phone and talk to them. If fire broke out in your house, you could not call the fire department (救火队). If somebody were sick ,you couldn't call a doctor.

　　　In our daily (日常) life we need to talk with each other. We do this 　22　by speaking to others and listening to what they have to say to us, and when we are close to them we can do this very easily. But, our voices will not travel very far even when we 　23　, and it is thanks to the invention of the telephone that we are able to talk with one another and ask something when we are in different places. We can hear each other as clearly 　24　we were in the same room.

　　　Alexander Graham Bell made this possible. He spent all his spare time experimenting (实验)。 He worded so hard in his research that he had 　25 　time to make money (挣钱) and was very poor at one time.
