6、d about 20 minutes on Questions 1-13, which are based on Reading Passage 1below.Pulling stings to build pyramidsNo one knows exactly how the pyramids were built. Marcus Chown reckons the answer could be hanging in the air.The pyramids of Egypt were built more than three thousand years ago, and no on

7、e knows how. The conventional picture is that tens of thousands of slaves dragged stones on sledges. But there is no evidence to back this up. Now a Californian software consultant called Maureen Clemmons has suggested that kites might have been involved. While perusing a book on the monuments of Eg

8、ypt, she noticed a hieroglyph that showed a row of men standing in odd postures. They were holding what looked like ropes that led, via some kind of mechanical system, to a giant bird in the sky. She wondered if perhaps the bird was actually a giant kite, and the men were using it to lift a heavy ob

9、ject.Intrigued, Clemmons contacted Morteza Gharib, aeronautics professor at the California Institute of Technology. He was fascinated by the idea. Coming from Iran, I have a keen interest in Middle Eastern science, he says. He too was puzzled by the picture that had sparked Clemmonss interest. The o

10、bject in the sky apparently had wings far too short and wide for a bird. The possibility certainly existed that it was a kite, he says. And since he needed a summer project for his student Emilio Graff, investigating the possibility of using kites as heavy lifters seemed like a good idea.Gharib and

11、Graff set themselves the task of raising a 4.5-metre stone column from horizontal to vertical, using no source of energy except the wind. Their initial calculations and scale-model wind-tunnel experiments convinced them they wouldnt need a strong wind to lift the 33.5-tonne column. Even a modest for

12、ce, if sustained over a long time, would do. The key was to use a pulley system that would magnify the applied force. So they rigged up a tent-shaped scaffold directly above the tip of the horizontal column, with pulleys suspended from the scaffolds apex. The idea was that as one end of the column r

13、ose, the base would roll across the ground on a trolley. Earlier this year, the team put Clemmonss unlikely theory to the test, using a 40-square-metre rectangular nylon sail. The kite lifted the column clean off the ground. We were absolutely stunned, Gharib says. The instant the sail opened into t

14、he wind, a huge force was generated and the column was raised to the vertical in a mere 40 seconds.The wind was blowing at a gentle 16 to 20 kilometres an hour, little more than half what they thought would be needed. What they had failed to reckon with was what happened when the kite was opened. Th

15、ere was a huge initial force- five times larger than the steady state force, Gharib says. This jerk meant that kites could lift huge weights, Gharib realised. Even a 300-tonne column could have been lifted to the vertical with 40 or so men and four or five sails. So Clemmons was right: the pyramid builders could have used kites to lift massive stones into place. Whether they actually did is another matter, Gharib says. There are no pictures showing the construction of the pyramids, so there is
