Science and technology
In the past people didn’t use technology – they used only simple tools made of stone. Later
they invented a wheel.
Today science and technology is very important to people. People use technology every day, for example:
- at home
- at work
- at school
At home we
use these inventions:
- a washing machine – we use for washing our clothes
- a hoover –
we use for cleaning our carpets /koberce/
- a fridge – we use to keep our food cold
- a microwave
oven – we use it to warm our food
- paper – we use at home, at school or at work when we want to write
something
- pen – we use for writing
- a telephone – we use when we want to call our
friends and family
- a television – we use when we want to watch a film or news
At work
we use:
- a fax machine – we use it when we want to send written information to people
-
a telephone – we use to make business calls
- a photocopier /kopírka/ - we use it when we
want to make a copy
- paper, pen and so on
People invented also many other important inventions, for
example:
- a bus / a train / a car – people use it for traveling
- credit cards – we use
credit cards, when we go to bank or when we want to pay in a shop
In the field of medicine
people also invented many important inventions, for example:
- X-ray – it is used for example when people
break a leg or an arm
- penicillin – it is a pill which we take when we are ill
- vitamin pills
/vitamínové tabletky/
- laser – doctors use laser to operate for example eyes
Dangerous inventions: people invented also inventions, which are not good for us. These inventions are dangerous, because they
can kill and destroy everything, for example:
- bombs
- weapons
Every day I use
many inventions, but I think that the most important invention to me is a mobile phone – I use a mobile phone:
- to call my
friends
- to send messages
- to play games
- to take pictures
- to listen to music
To me, another important
invention is a computer – I use a computer:
- to do my homework
- to play games
- to write an e-mail
- to find information on the internet
- to chat with friends
Science and technology brought people many advantages and
disadvantages.
The advantages are for example:
- science and technology makes our life easy and comfortable
-
we can weigh and measure easily
- we can learn new information about people, animals and life
- we can save many human lives
-
we can travel easily
The disadvantages are for example:
- technology can be dangerous and it can kill people
– for example bombs
- science brought ethical problems – people want to clone animals, people…
- we can destroy the nature –
technology pollutes environment – for example cars, buses
- we don’t talk and visit our family and friends often, because we send messages
and watch TV a lot – we don’t have time for them
Older people and technology:
Older people usually
don’t like technology. For example my grandmother and grandfather don’t use a computer or a mobile phone. These inventions didn’t exist when
they were young and they don’t need them or they don’t know how to use them. They think that technology is not important because they have never
needed it.
We know many famous inventors, for example:
- James Watt – he invented the steam engine
-
Thomas Alva Edison – he invented the electric bulb
- Alexander Graham Bell – he invented the
telephone
- Albert Einstein – he developed the theory of relativity
- Sir Alexander Fleming – he
invented penicillin
Today the life without technology would be difficult, because people are lazy and spoilt.
