2. There is an open book on the blanket on the bed.

3. There are some books on the shelf on the wall.
(Are they grammatical? Would you check them? Thank you.)

Answer 1

These are perfect grammatically correct sentences, dude. :D

Answer 2

herp is right. These are really good. One thing, though:

In #1, use either "is" or "lies" (not "lays"). It's that tricky pair of verbs that many English speakers don't get!
