Suppose a man has a car accident．He is hurt badly and is unconscious, that is, he can't think, speak, or hear．His family takes him to the hospital．The doctors tell the family that his brain is dead．A machine can make him breathe．
Now the patient's family must answer some difficult questions．Should they think he is dead?Should they ask the doctors to use the machine to make him breathe? Sometimes machines can make an unconscious person breathe for years．However if his brain is dead, he will never think, speak, or hear again．Then, should his family ask the doctors not to use the machine and let him die?
Someone who is unconscious can't say he wants to die．Can his family say this for him?Some people think this is a good idea．Some think not．
Many people are hurt when machines keep a person alive．The unconscious person doesn't know it．Machines only make the family and friends hurt longer．

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．
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．
