In the middle (of the room) there are four green chairs round the table. The man is sitting on the chair(,) (niepotrzebny przecinek) at the table, eating (brak porzedimka) meal and watching TV.
She is sitting in the green armchair and reading (brak przedimka) book.
Her face is 'intent' (zle slowo, poszukaj innego) so I think the book is very interesting.
'It's' (lepiej dac 'He's ) eating a big bone. 'It' HE has 'a' (nie dajemy przedimka przed l. mnoga) brown dapples on his fur.
In the background you can see 'the' (wg mnie tutaj ma byc 'a') black set television on the cabinet.
