1. Computers have already
revolutionized the way we live and work. But it is early days for computers. We
do not know how much they are still changing the world. Already, Internet users
can buy things and study holiday offers. It's much easier to edit and print
documents using a PC. More computer wonders are yet to come.

2. Only a few years before men were
walking on the moon, reputable scientists declared that it was impossible. But
in 1969 Neil Armstrong stepped out of his space capsule and made his famous
statement, ‘That's one small step for a man, one giant leap for mankind.' However,
progress in this area is slower now. Not as much money goes into research as in
the 1960s.

3. Surely nothing has done more for
the comfort and happiness of mankind than the advance of medical knowledge!
Lots of people have benefited from the aspirin and lots of lives have been
saved by penicillin. Surgeons can perform the most amazing operations. Average
life expectancy in Europe has risen
dramatically over the last hundred years.

4. In the past, a holiday used to
mean simply a day when you did not work. Now millions of holidaymakers travel
to all parts of the world. Perhaps, not all people like to see lots of tourists
in their countries, but we must admit that a phenomenon which sees the
population of Greece
treble is a wonder of the world.

5. It is true that the Olympic Games
are now commercialized and there is greed and drug abuse. However, it is a
competition in which every country of the world takes part. Every four years,
for a brief moment, we see these countries come together in peace and friendship.
We see people from warring countries shake hands. We feel hope again for the
future of mankind.

6. In 1724, Jonathan Swift wrote,
'Whoever makes two blades of grass or two ears of corn grow where only one grew
before serves mankind better than the whole race of politicians.' In Europe farmers have done it and we produce enough food to
feed the world. If only politicians could find a way to share it with those
parts of the world where there is still famine.

7. The greatest wonder of the modern
world is simply that we are still here. We have bombs that could destroy the
world but we try our best not to use them. Because of people's effort no
government dares to use such weapons. The year 2001 marked the 100th
anniversary of the Nobel Peace Prize, the most famous attempt to raise
awareness of the issues of war and peace.
