To Mr. Alan: book expressions?

[Tortoise]

Hi, Mr. Alan

Your lesson book expressions is very interesting. But I have difficulty understanding some expressions which can not be looked up in my dictionaries. May you help me?

1. a closed book (to someone)

2. an open book

3. to throw the book at someone

4. "Take a leaf out someone's book" or "Take a leaf out of someone's book" ?

In your lessons "Colour Idoms".

5. You say "Oh, come one,.." I think it's "come on", isn't it?

6. black ice

7. "white" in the sentence "The trouble was she had set her heart on a particular colour — white. It had to be white at all costs".

8. blue in the face

9. white flag = surrender (noun) ?

10. Give the meaning of this sentence "We looked at dozens of white and off white cars but none seemed to be worth buying".

Thanks in advance.
