The Building of the Pyramids
The oldest stone buildings in the world are the pyramids. 46 There are over eighty of them scattered along the banks of the Nile, some of which are different in shape from the true pyramids. The most famous of these are the “Step” pyramid and the “Bent” pyramid.
Some of the pyramids still look much the same as they must have done when they were built thousands of years ago. Most of the damage suffered by the others has been at the hands of men who were looking for treasure or, more often, fore stone to use in modern buildings. 47 These are good reasons why they can still be seen today, hut perhaps the most important is that they were planned to last for ever.
48 However, there are no writings or pictures to show us how the Egyptians planned or built the pyramids themselves. 49 Nevertheless, by examining the actual pyramids and various tools which have been found, archaeologists have formed a fairly clear picture of them.
One thing is certain: there must have been months of careful planning before they could begin to build. 50 You may think this would have been easy with miles and miles of empty desert around, but a pyramid could not be built just anywhere. Certain rules had to be followed, and certain problems had to be overcome.
A The dry climate of Egypt has helped to preserve the pyramids, and their very shape have made them less likely to fall into ruin.
B It is practically certain that plans were made for the building of the pyramids because the plans of other large works have fortunately been preserved.
C The first thing they had to do was to choose a suitable place.
D Consequently, we are only able to guess at the methods used.
E Many people were killed while building the pyramids.
F They have stood for nearly 5,000 years, and it seems likely that they will continue to stand for thousands of years yet.

Singing Alarms Could Save the Blind
If you cannot see, you may not be able to find your way out of a burning building —and that could be fatal. A company in Leeds could change all that 51 directional sound alarms capable of guiding you to the exit.
Sound Alert, a company 52 the University of Leeds, is installing the alarms in a residential home for 53 people in Sommerset and a resource centre for the blind in Cumbria. 54 produce a wide range of frequencies that enable the brain to determine where the 55 is coming from.
Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be 56 by humans. “It is a burst of white noise 57 people say sounds like static on the radio,” she says.“Its life-saving potential is great. ”She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of a large 58 room. It 59 them nearly four minutes to find the door 60 a sound alarm, but only 15 seconds with one.
Withington studies how the brain 61 sounds at the university. She says that the 62of a wide band of frequencies can be pinpointed more easily than the source of a narrow band. Alarms 63 the same concept have already been installed on emergency vehicles.
The alarms will also include rising or falling frequencies to indicate whether people should go up 64 down stairs. They were 65 with the aid of a large grant from British Nuclear Fuels.
