雅思阅读辅导：Clemmons的风筝理论　　阅读段落 　　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.
There 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 realized.
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 no way to tell what really happened.
The evidence for using kites to move large stones is no better or worse than the evidence for the brute force method, Gharib says.
