Technology and the young

Modern technology is changing and improving all the time. Every month, scientists            [estimate, invent, involve, experiment] new gadgets and              [experiments, effects, laboratories, equipment]to help us with our daily lives, and          [involve, discover, decrease, connect]ways to make existing technology faster and better. Our homes are full of hardware (such as DVD players and computers) and          [screens, gadgets, software, laptops](such as computer games and MP3s).

           [Research, Experiment, Program, Technology]suggests, however, that it's young people who are best able to deal with this change. Whereas teenagers have no problem             [involving, operating, discovering, inventing]a DVD player, their mums and dads and grandparents often find using new technology             [automatic, unique, sudden, complicated]and difficult.

But if you're a teenager who criticises your parents for their            [research, experiment, effect, lack]of technological awareness, don't be too hard on them! Some time    [to, in, on, at]the future, when you’ve got children of your own, your ability to deal with new technology will probably          [decrease, involve, lack, estimate] and your children will feel more comfortable with new technology than you do. You won't want them to criticise you, will you?
