     Nowadays, we can know time very easily．Even a little child may know the time．We always ask

"What time is it?" Then people can tell me the exact time．But before the invention of clocks, it was

very difficult．One way people told the time was by using sundials, but it was impossible to tell the time

on cloudy days or at night．

     The first mechanical(计时)clock was invented in China by Su Sung in 1088．The first clock in

Europe was invented 195 years later, at the end of the 13th century．And in Britain, 67 years later, the

alarm clock was invented in Germany.

     The first watch was invented in Italy in 1462. Early watches were different from today's in two main

ways．First, they only had an hour hand．Second, you could not wear them on your wrist. (手腕)You

had to keep them in your pocket- that's why they were called 'pocket clocks'．

     The first wrist watch came from Switzerland 328 years after the first pocket clock, but nobody bought

them．They did not become popular for a hundred years．

time-keeping．Shops all over the world started to sell them in 1971.
