How long have you known Boris? - We know each other from childhood. 6. I have this hat for five years. - True? And I never wear a hat for so long. What are you doing? - I'm writing an essay. "Have not you finished yet?" You've been writing for three hours already! 7. Where is Anna? "She works in the garden." She's been there since the morning. - What is she doing? - Planting trees. She has already planted ten trees. 8. I'm working on a new novel. I write ten pages a day. Today I have already written six pages. 9. Why are you so wet? - I bathe (to bathe) the child.

I think, everybody will agree, that it-tecnologes become more and more neseccery at our life. And now, instead of buying new paper books, we can download it to E-books.And i prefer E-books, bevuase We can have a million poems, stories and articles at little modern gadget. Also, we van download Audio-book, and listen this book, than yoy cant read that. At other hand, we have a big inflence to our vision and health at all. Another disadvanteger is price, because E-books much expensive than printed books.
So, at the resalt we have more benefits, than minuses. And i take a vishion, that E-books much better than Printed Books.
