Book p.2 Mary read a very interesting book telephones. How the Telephone Was Invented Do you have a telephone in your home? Who uses it? Do you use it ? Today, most of us have telephones in our homes. One hundred and twenty years ago ,people were not so lucky. Alexander Graham Bell invented the telephone. He was very interested in how human beings make and hear sounds because he taught deaf people. He learnt about how the human ear hears sounds and began to experiment with sending sounds.
Book p.3 In those days, people sent messages by telegraph. At that time, telegraph messages could only be sent one at time. Bell improved the way telegraph Messages could be sent down one wire at time. Bell experimented some more and invented a microphone that could send sounds down a wire . Then, he invented a receiver that could collect incoming sounds. These became the two main parts of a telephone.
Book p.3 One day, Bell called out to his assistant over the microphone, “Mr.Watson, come here !I need your help !” At that time, Mr.Watson was on a different floor of the building. But he heard Bell’s voice clearly over the new device. He ran to help Bell and to tell him the good news. Bell had invented the first telephone, It was 10th March 1876.
Mary remembered that her cousin, Angel was doing a project on inventors. She decided to share the information she read with Angel. Complete Mary’s e-mail below with suitable words from the text on pages 2-3. Book p.4
