Infine prepara un esposizione orale di 3 minuti sull argomento. An electronic book (or e-book, ebook or digital book) is a book in digital form. E-books can be read on computers, or on e-book readers. The first modern e-book was invented by Michael Hart in 1971 at the University of Illinois. The first document he read on the new device was the U.S. Declaration of Independence. Since the 1990s, the Internet has made transferring electronic files much easier, so e-books have become more and more common. E-BOOKS PROS They take up less space: you don t need shelves for them. No trees are required to make the paper. They show you links to get further information. CONS They aren t good for your eyes: they have a glare that may make reading uncomfortable. They require power (e.g. for batteries) They are made of plastic and that is bad for the environment. USEFUL WORDS device = apparecchio, dispositivo; glare = luce abbagliante; reader = lettore. 38
