The electronic age I recently learned how to use a computer and I have many friends who they play computer games at home. However although recently I have begun to worry that in nowadays we rely too much on electronic gadgets. Once before people managed to write and think using their brains but now many people have become so accustomed to using machines so that they can t do anything without them. There are many people who they depend on electronic gadgets completely. For an instance many of my friends sit at home in the evening and watch television and instead of going out so to meet people. I think that this makes everybody feel more lonely even though they learn a lot about people all over in the world.

I am in favour of some gadgets but I am against of having everything in life depending on pushing a button. . 1 . 2 . 3 . 4 . 5 . 6 . 7 . 8 . 9 . 10 . 11 . 12 . 13 . 14 . 15 . 91 Explanations Ability Can and be able to Can like all modal verbs cannot be used in an infinitive or continuous form.
