We are all used to reading the book in a standard form. Proposals consisting of words written down on paper and collected in one single collection of papers - this is the book. But, in our modern world came up with other formats for more comfortable and convenient reading. Current electronic books, they are much different from ordinary books. First we must notice that electronic books, this is technology. About the possibility of comparing them with simple books, we can mention a lot;Reading is not on ordinary sheets, but on a flat screen. Downloading book files to an electronic device.Change the brightness when reading, convenient font size and without any effort to know on which page you are staying. This distinguishes them from ordinary books.

Перевод:
Мы все привыкли к чтению книги в стандартном виде.
Предложения, состоящие из слов записанные на бумаге и собранные в один единый сборник бумаг - это и есть книга. Но, в нашем современном мире придумали и другие форматы для более комфортного и удобного чтения.
Нынешние электронные книжки, они многим отличаются от обычных книг. Сперва должны подметить что электронные книги, это - технология.
Про возможности и сравнения их с простыми книгами можно упомянуть многое;Чтение не на обычных листах, а на плоском экране. Скачивания файлов книг на электронный прибор.Изменение яркости при чтении, удобный размер шрифта и без каких-либо усилий знать на какой странице вы остановились.
Это и отличают их от обычных книг.

Hare goes at night through fields and forests without fear and paves the direct traces; but as soon as morning comes, his enemies awake:

hare starts to hear the barking of dogs, the screeching of the sledge, the voices, the crackle of a wolf in the forest and starts from fear waver. Проскачет forward, scared of something and run back on his trail. Still hear anything - and with the entire span will jump aside and jump away from the previous track. Again banging something - again hare turn back and again will jump aside. When light will, he lieth down.
