hi everybody this is mr. Duncan England
how are you today are you okay I hope so
in this lesson we're going to talk about the complicated and some would say
forever changing world of modern technology
in the beginning there was darkness computers DVD players and ipods did not
exist there were no cellular - no jet aeroplanes
no microwave ovens and no internet yes before technology came along the world
the word technology generally relates to any complicated tool that has been
created to carry out the task of some sort this task can be a simple one such
as adding up numbers right up to the really complex ones such as steering a
jumbo jet or sending a rocket into space
there are some other words that relate to technology such as electronics
high-tech microtech & Info Tech these days
virtually all modern technology is powered by electricity for example
televisions radios mp3 players
cellular phones washing machines notebook computers even the good old
toothbrush the list is endless
do you mind if I take your photograph is it ok ok give me a lovely smile go on
said cheese CHEESE that's great
it would be fair to say that virtually all the great technological leaps
forward have occurred during the past 50 years since the discovery of electricity
our world has been magically transformed into an amazing wonderland where our
thirst for information can be quenched and imagination is allowed to run free
there are some people who are skeptical of our ultra modern way of living and say
that modern inventions such as the computer and television have made us
lazy and less in touch with the real world
other examples being the cellular telephone and the internet which critics
say have helped to make the world smaller while at the same time making
also we mustn't forget about the environmental impact that these energy
guzzling devices are making of course it is true that technology has been created
for bad purposes as well as good
nuclear power has enabled us to generate energy but it has also been used to
so I imagine perhaps in the future we could be using laser guns
just like in the science fiction movies
it is amazing to think of how much the world has changed because of all the new
many of the devices we use today would have been mere fantasy and science
it proves one very important rule if it can be imagined it can be created
I wonder what our world will be like in another 50 years
can you imagine what it will be like living then flying cars
fusion power maybe even a time machine will be invented by then I could travel
back to the past and visit myself as a child
do you own what are your favourite electronic devices
do you think you could live without them
it is amazing to think that without all these incredible inventions
I would not be able to stand here today and talk to you
many of the things we can do today have been made possible thanks to our own
this is mr. Duncan via the internet saying thanks for watching and bye bye
