Man’s story in China began many thousands of years ago. Remains of an early form of man discovered in China, known as Peking Man, indicate that Stone Age men lived in the area as long as 500,000 years ago. During the centuries that followed, their descendants laid the foundations of civilization in China.
Throughout its history, China has been a rich source of inventions. Silk, the compass, tea and porcelain originated there. In addition, they are responsible for the invention of paper and printing. The Chinese had used ink as early as 1200 B.C., an excellent type which they made from lampblack and which is known in English as India ink or China ink. By the end of the first century A.D., the Chinese had invented paper.
The Chinese also invented printing. Early Chinese printing is called block printing. The printer carved raised characters on a block of wood, wet the surface of the characters with ink, and pressed sheets of paper against them.

Passage 2
In recent years many countries of the world have been faced with the problem of how to make their workers more productive. Some experts claim the answer is to make jobs more varied. But do more varied jobs lead to greater productivity The evidence shows that while variety certainly makes the worker’s life more enjoyable, it does not actually make him work harder.
