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．

You will have a lot of reading to do in this grade this year．You can do more of it in less time if you learn to read rapidly．
Perhaps you have been told about some habits (习惯) which keep a person from reading fast and have been strongly asked to break those habits which you might have．
Do you still have any of these bad habits?Check yourself by answering“yes”or“no”to these questions．
(1) Do you move your lips (嘴唇) when reading silently?
(2) Do you point to words with your finger as you read?
(3)Do you move your head from side to side as you read?
(4)Do you read one word at a time?
If you answer“yes”to any of these questions,start at once to break the habit．If you move your tips，hold your fingers over them，or hold a piece of paper be-tween your lips while you are reading．Then if your lips move，your will know it and can stop them．
If you point to words，hold the two sides of your book，one side with your left hand，the other side with your right hand．Then you won't have a free finger to use in pointing while reading．If you move your head，place your chin (下巴) in one hand and hold your head still (静止不动的)．
If you read no more than one or two or three words at a time，you need to work very hard in learning to take in (吸收) more words at each glance (一瞥) as your eyes travel across the lines of words．
Even if you do rather fast now，you can learn to read even faster．As you probably have been told，the secret of fast reading is to take in whole groups of words as each glance．Read in through groups and force (迫使) your eyes along the lines of words as fast as you can to make them go．Anyone who practices doing these things will he able to read faster．
