We can’t live without tecnological materials becuase they give  us easier life . Life is so hard and and technology  helps us. 
Mobile phone is a great example. We can’t to talk to people who are in countries. We can surf on the net. We can share photos , videos , update to status. We can play games , listen to music  , calculate , take photos , read news , record our voice etc.
   There are computer in every house. Many years ago  we were using for our work but now we are using for our pleasure. We can’t avoid computer but we must not depend on computers very much.
   As for as we know , first computers could only calculate and it was as big as room . But now , it is very small and we can take it everywhere with us.
   And other technological materials are washing machine , tv , radio , fridge etc… We need them.
