Thousands of years ago people guessed the time of day by watching the sun.

Later,they found it was easier to tell the exact time by looking at the shadows. Thus, the sundial(日晷) was invented.

The sundial proved a useful timepiece in sunny weather. However,another type of timepiece was necessary  for cloudy weather and nigh time. A sand glass was another common measurer of time. Two glass bottles were connected by a very small opening. The top bottle was filled with sand,which dropped slowly into the bottom one in a certain period of time. Hour glasses were widely used then. Three-minute sand glasses are still used in many homes to time the boiling of eggs.

The real ancestor of modern clocks was the water clock. In China ,an early  water clock was made up of several bowls. Water trickled(滴) from one bowl to another to keep the clock  going. Visitors to the  Beijing Palace Museum can still see the old  water clocks showing the time there.

In the Middle Ages a waterless clock was invented which worked by means of  weights. To keep the weight falling at the same  speed,a system of wheels was invented. The pendulum(钟摆) was soon developed to control the speed of the wheels. Thus the modern form of clock came into being.

Net Libray is a library that lends out digital books. It treats a digital like a paperback copy. It charges libraries per book per copy and gives publishers a cut of the total income.

From the consumer’s point of view,this means that if more than,Say, five people want the latest Danielle Steel romance novel,other people who request  that book will get a message saying the title can’t be found.

It’s a model many publishers seem to have embraced. More than 350 gave the  company rights to hand out their digital works,and McGraw-Hill Corporation and  Houghton Mifflin Corporation have put money in the company. The California public  libraries and about 1,800 others across the US are trying out the Net Library service.

Some librarians criticize the New Library model. Stanford University librarian  Michael Keller argues that the company is creating an unnatural fear of digital woks,  which is contrary to the ideas of the Internet.

Kelle and some  other  librarians argue  for  the  e-book  vision  set forth by E-Brary. E-Brary is starting a service that lets us users read books for free.

  But it will charge about 25 cents a page when a person tries to print out material or copy and paste it into a different file or tries to download copy onto a computer.

Christopher Warnock,chief executive of E-Brary, believes most consumers won’t want to buy entire books,only the parts that interest them.

“There’s not really a lot of good in owning an electronic file and having to store it and manage it. It doesn't make sense.” he said.
