Pyramids
The Egyptian pyramids are the best known archaeological monuments in the
world,partly to their distinctive and instantly recognizable design. For all the Middle
East and the Western world the Pyramids and their guardian Sphinx have become
symbols of eternity. Over the years they have captured worldwide attention and with it, a
multitude of speculative theories.Speculation over the origin of these grand monuments
of stone started with the Greeks.They thought that pyramids were constructed as a
memorial to the wicked King Khufu’s daughter- a princess who had led a very sad and
difficult life. Another theory is that pyramids were large stonehouses for grain, which
were built in preparation for the famine that was predicted in the Bible. Arab
philosophers saw this pyramids as werehouse for Egyptian scientific and medical
wisdom that would otherwise have disappeared during the Grate Flood.another theory is
that pyramids could be a mechanism of predicting the future or even as a road sign for
alien, or the means of predicting the apocalypse.it is thought that the man working on the
pyramids actually did so as a form of taxation and not under the master’s whip or out of
religious duty,as was previously thought.Some of them were respectable architectors.
There are some problems connecting with mass tourism.The benefits of the building of
the Aswan High Dam are undeniable: it controlled the flooding of the Nile, releasing
more land for agriculture and providing more water for irrigation. The problems of
underground water have been exacerbated by the presence of sewage leaking into the
ground from Cairo's inadequate drainage system. In 1900 Cairo had a population of
around one million; today it is nearer 14 million, and there has been no appreciable
expansion of the sewage system.If international rescue efforts are successful, the
preservation of the Nile Valley monuments can act as a model for the rest of the world's
ancient structures.
Future life
Can you imagine what our lives will be like in the year 2050&
Perhaps you will be flying off for a holiday on the moon, or maybe
you will be taking your dog for a walk in a virtual reality. We recently
carried out a survey of 1000 people from different countries to find
out what they think life will be like in the future. The results clearly
demonstrate both our hopes and fears. The survey suggests that
friendship- one of the most important human relationships-will have
changed dramatically. People will make friends through the internet.
What is more a large number of people will even come across their
future husbands or wifes in this way. Computers will have become
absolutely essentiasl by 2050. even now, some people describe them
as their best friend, others however say that we will become much
more isolated from each other because we will have little real human
contact.
Educcation will have changed a lot too. As more and more children
will be using computers in schools,certain abilities, such as mental
arithmetic, wont\t be necessary since there will be computer programs
for most calculations.even writing by hand will have become a thing
of the past. According to the survey, home life will be better, Most
people that by 2050 robots will be doing the housework and we will
be eating ready-made food, A lot of people think that we might only
cook for fun in the future.
Space exploration will become increasingly popular. Fifty per cent of
the people we talked to believe that travel on our own planet will
probably cnange. Almost everyone thinks that there will be no cars in
the city cantres.Some even think that environmentally-friendlly
electric or solar-powered cars we use nowadays.
Pollution is something that seems to worry many people. Some fear
that it will continue to get worse and that one day we will have to pay
for clean air just like we do now for clear water. On the other hand
people seem to be quite optimistic about the benefits of genetic
engineering as they think scientists will use it to find a cure for these
we will have a much healthier society.
Some peope worry about the future while others are full of hope and
enthusiasm. No matter how dark or bright it may seem it is up to us to
look after our planet and try to make it a better place to live.
Living on the edge
Volcanic eruptions have been a fact of life since the earth first formed
as a solid planet, and they have taken a huge toll of human life over the centuries. One of
the earliest recorded disasters was the Vesuvius eruption in AD 79 which buried the
Italian city of Pompeii under ash, killing an estimated 16,000 people. The most violent
eruption of modern times was in Krakatoa, Indonesia, in 1883 when more than 36,000
people were killed and debris was scattered across the Indian Ocean as far away as
Madagascar, off the east coast of Africa.
There are about 500 active volcanoes in the world today, though it is
always unsafe to assume that any volcano is on the retired list. The types of eruption
vary greatly. The simplest kind, found in Hawaii and Iceland, is a more or less
continuous fountain of fire, sometimes reaching incredible heights. Next in order of
complexity are eruptions that follow the Stromboli (a continuously active volcano off the
northeast coast of Sicily) pattern, where the lava is less fluid and the rate of eruption is
not so high – from one every few seconds to one every couple of hours.
But even well behaved volcanoes can turn nasty if water gets into
them. It boils to produce steam and this increases explosive power.
Even more dangerous is the nuée ardente – a burning cloud – which
would kill anyone caught in it almost instantly. It occurs in volcanoes where the lava is
viscous and rich in gas. The eruption of Pinatubo, in the Philippines, in 1991 has affected
the entire world population. More than a year after the eruption, a belt of ash and
chemicals still circles the Equator at an altitude of about 20 miles, disrupting the ozone
layer and the planet's climate.
There are 15 capital cities in the world in a position to be wiped out or
seriously damaged by volcanic eruptions. So why do people continue to live alongside
them? Many are poor and have little choice, while others disregard the risk – which is
after all, rather less than smoking or driving a car. But it is the land around volcanoes
which attracts people; the soils from volcanic ashes are light, easily worked, drain well
and are full of plant nutrients. A light fall of ash, though it may destroy one year's crop,
pays back in future years by the fertility it adds to the soil. Coffee in Colombia, vines in
Italy, and rice in Japan are just a few of the crops that flourish on volcanic soils.
