They turned the pages, which were yellow and crinkly, and it was awfully funny to read words that stood still instead of moving the way they were supposed to -- on a screen, you know. And then, when they turned back to the page before, it had the same words on it that it had when they read it the first time.
`Gee,' said Tommy, `what a waste. When you're through with the book, you just throw it away, I guess. Our television screen must have had a million books on it and it's good for plenty more. I wouldn't throw it away.'
Please explain the highlighted group of words.
I guess, `the television screen' refers to `computer monitor screen'
and the highlighted `it' refers to (computer monitor screen).
Please help me.
