Look, Good e Took: Qual é a pronúncia correta?

Hi, everyone,

I'm trying to improve my pronunciation.
I would like you, guys, to participate and share examples of words spelling with "oo" that are not pronounced like food, loose, goose, taboo, boom etc. I guess these are much more common in English than the examples I pointed out in the title, with a relaxed and brief "oo". Let's write usual words and forget about words that you almost never need.
I believe it will be helpful to a bunch of students here.

So, let's get started:

Look
Good
Took
Book
Brook
Cook
Wood
Hood
