Problems with grammer

First sentence is: he didn't knew her well.

my bad it was just my suggestion

He didn't know her well.

Read pages 9 and 10 for tomorrow.


The house whose roof had been painted was very old.
or

The house the roof of which had been painted was very old.

He didn't know her well. - I cannot find a problem with this.

Read page 9 and 10 for tomorrow. - Read page numbers 9 and 10 for tomorrow.

The house which roof had been painted was very old. - The house whose roof had been p

Okay can someone explain why its know instead of new

And you two don't agree with "read page 9 and 10 for tomorrow" who is right?

And it is wrong if I have written "Read page 9 and 10 till tomorrow" or is the problem that there is pluralis and therefore "pages"?

And at last why is the problem whose instead of which?

as far as i know which can also be used abou

know instead of knew** sorry

The first one has a form of the verb "to do" so the main verb is in what's called the bare infinitive form (that is, the "to VERB" without the "to"). He knew her; he didn't know her; do you know her etc.

The second one reads more naturally to me as "pages" but I could live with "page number 9 and page number 10." You can read it for tomorrow or by tomorrow, but not till tomorrow.

Is this structure correctly?

The house which roof was very old had been painted.
