Переведите пожалуйста текст(не через переводчик)
Margie even wrote about it that night in her diary. On the page headed May 17, 2157, shewrote, "Today, Tommy found a real book!"
It was a very old book. Margie's grandfather once said that when he was a little boy hisgrandfather told him that there was a time when all stories were printed on paper.

They turned the pages, which were yellow and crinkly, and it was awfully funny to readwords that stood still instead of moving the way they were supposed to - on a screen, youknow. And then, when they turned back to the page before, it had the same words on it thatit had had when they read it the first time.
"Gee," said Tommy, "what a waste. When you're through with the book, you just throw itaway, I guess. Our television screen must have had a million books on it and it's good forplenty more. I wouldn't throw it away."
"Same with mine," said Margie. She was eleven and hadn't seen as many telebooks asTommy had. He was thirteen. She said, "Where did you find it?"

"In my house." He pointed without looking, because he was busy reading. "In the attic.""What's it about?" "School."
Margie was scornful. "School? What's there to write about school? I hate school."

Margie always hated school, but now she hated it more than ever. The mechanical teacherhad been giving her test after test in geography and she had been doing worse and worseuntil her mother had shaken her head sorrowfully and sent for the County Inspector.

He was a round little man with a red face and a whole box of tools with dials and wires. Hesmiled at Margie and gave her an apple, then took the teacher apart. Margie had hopedhe wouldn't know how to put it together again, but he knew how all right, and, after an houror so, there it was again, large and black and ugly, with a big screen on which all thelessons were shown and the questions were asked. That wasn't so bad. The part Margiehated most was the slot where she had to put homework and test papers. She always hadto write them out in a punch code they made her learn when she was six years old, and themechanical teacher calculated the mark in no time.

The Inspector had smiled after he was finished and patted Margie's head. He said to hermother, "It's not the little girl's fault, Mrs. Jones. I think the geography sector was geared alittle too quick. Those things happen sometimes. I've slowed it up to an average ten-yearlevel. Actually, the over-all pattern of her progress is quite satisfactory." And he partedMargie's head again.

Margie was disappointed. She had been hoping they would take the teacher awayaltogether. They had once taken Tommy's teacher away for nearly a month because thehistory sector had blanked out completely.

So she said to Tommy, "Why would anyone write about school?"

Tommy looked at her with very superior eyes. "Because it's not our kind of school, stupid.This is the old kind of school that they had hundreds and hundreds of years ago." Headded loftily, pronouncing the word carefully, "Centuries ago."

Margie was hurt. "Well, I don't know what kind of school they had all that time ago." Sheread the book over his shoulder for a while, then said, "Anyway, they had a teacher."

"Sure they had a teacher, but it wasn't a regular teacher. It was a man." "A man? Howcould a man be a teacher?" "Well, he just told the boys and girls things and gave themhomework and asked them questions." "A man isn't smart enough." "Sure he is. My fatherknows as much as my teacher." "He can't. A man can't know as much as a teacher." "Heknows almost as much, I betcha.
