A

　　Bi Sheng was a common printer in the Song Dynasty. About a thousand years ago books were printed from whole wooden blocks. Carving (雕刻) one block took weeks, and a single mistake could ruin (毁掉) the whole block. Bi Sheng wanted a faster and cheaper way.

　　Around 1041 he came up with a new idea. He cut single Chinese characters on small pieces of clay (黏土), so each character became a small block. The blocks were baked hard in a fire. When a page was to be printed, the blocks were set in an iron frame and pressed flat. After printing, the blocks were taken apart and could be used again.

　　Bi Sheng's movable type (活字) was one of the greatest inventions in Chinese history. His idea later travelled to other countries. Today, although we print with machines and computers, the idea behind movable type is still the same: make one piece for one character, then use the pieces again and again.

A. Around 1041.　　B. Around 941.　　C. Around 1141.　　D. Around 1941.

（　）27. What did Bi Sheng make the type with?

A. Wood.　　B. Iron.　　C. Clay.　　D. Paper.

（　）28. Why was movable type better than whole blocks?

A. Because it was heavier.　　B. Because it was more beautiful.　　C. Because it was made of iron.　　D. Because the blocks could be used again.

（　）29. What does the underlined word "baked" mean in Paragraph 2?

A. cooled　　B. broken　　C. heated　　D. painted

（　）30. What is the best title for the passage?

A. Bi Sheng and Movable Type　　B. The Song Dynasty　　C. How to Carve a Block　　D. Printing in Europe

B

　　Orville and Wilbur Wright ran a small bicycle shop in Dayton, Ohio. They were not scientists and they never went to university, but they loved machines and they read everything they could find about flight.

　　On 17 December 1903, at Kitty Hawk, North Carolina, their plane, the Flyer, was lifted into the cold wind. The first flight lasted only twelve seconds and covered about 120 feet — shorter than a modern plane is long. But it was the first time in history that a machine carrying a man had flown under its own power.

　　The brothers did not stop there. By 1905 they had built an airplane that could fly for more than half an hour. Their success was built on hundreds of tests, careful notes and one simple idea: try, fail, learn, and try again.

A. They were teachers.　　B. They ran a bicycle shop.　　C. They worked in a factory.　　D. They were doctors.

A. Twelve minutes.　　B. Half an hour.　　C. One hour.　　D. Twelve seconds.

（　）34. What was the brothers' success built on?
