     From the early days of history people looked for ways of telling the time, but it was not until the thirteenth century that machines for telling the time
were invented.These first clocks were very big. They had no faces or hands
but they did have a bell. It rang every hour.
     In the seventeenth century, people began to use clocks with faces and
hands and to carry small clocks with them.
     For a long time after that, men and women had pocket watches. These
were usually tied (检) to a button (纽扣) on the person's clothes.
     It is strange that wristwatches were not used until about 1914. The man
who made the first popular watch was walking in a park one day. There he
saw a woman with a pocket watch tied to her wrist (手腕) , she was feeding
her baby and she needed to have both hands free to hold the child.
     Now nearly everybody wears a watch all the time. If you have a
"waterproof"  watch, you don't even have to take it off when you go
swimming. Aboul 80 million wat-ches are made every year.
