out of and from are pretty much interchangeable, when you are talking about materials something is made of, or an abstract concept that is derived from some thing or activity.
With is not quite the same, as it suggests adding something rather than deriving something. You could not, for example, say
I get a lot of enjoyment with teaching - not natural
but you can say
Birds make nests with branches or twigs.
because the birds are adding twigs to the nest, rather than for example shaping a twig to make a nest.
Someone had torn several pages out of her diary
In my opinion, this sentence uses the the compound verb tear out. You could use from, but the original version is much more specific.
tear out means to remove something completely by pulling hard, for example you can talk about somebody tearing their hair out.
On the other hand, tear means to pull apart, or to pull pieces off. So,
Someone had torn several pages from her diary
could mean:
- somebody pulled the pages out completely
- somebody pulled the pages apart, ripping the pages into small pieces
- somebody pulled pieces off the pages, for example ripping off the top corner from each page.
You could, of course use from together with tear out, like this:
Someone had torn out several pages from her diary
