4 несушествующих знаков в природе, рисунок и обьяснение​

1 To my mind reading is less popular now with teenagers than it was before
 the computer came into our lives. I think they read less because of lack of time.
2 I like to read different kinds of books:  historical novels and books on geographical discoveries, about life of famous people and culture of different countries and many other kinds of books both paper books and electronic ones.
3 Many people prefer e-books to paper books because they don't occupy much room as paper books do, it's often easier to find the necessary book on the net than in the library or in the shop. E-books are much cheaper as compared to paper books and besides you may find them recorded and then you don't need to read them yourself, but just switch on the record and listen to the actors who read the text. It's quite helpful. You don't need to strain your eyes. There are of course other arguments: for example, it's unpleasant to deal with old dusty books because many people are alergic to book dust.
That's why many people prefer e-books to paper books.
