"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．
Digital clocks and watches came from the United States and are the new popular inventions in
time-keeping．Shops all over the world started to sell them in 1971.
