My favourite room

Тhe room in
our house (l) ______is our kitchen. Perhaps the kitchen is the most important
room in many houses, but it is particularly so in our house because it's not
only (2) ______, but it's also the place (3) _______.

I have so many happy
memories of times spent there: ordinary daily events such as making breakfast
on dark, cold winter mornings for children (4) ______, before sending them off
to school; or special occasions such as homecomings or cooking Christmas
dinner. Whenever we have a party, people gravitate with their drinks to the
kitchen. It always ends up the fullest and noisiest room in the house.

So what does this
special room look like? It's quite big, but not huge. It's big enough to have a
good-sized table in the centre, (5) ______. There is a large window above the
sink, looking out onto two apple trees in the garden. There's a big, old
cooking stove at one end, and at the other end a wall with a huge notice board
(6) ________of our lives, past, present, and future: a school photo of the kids;
a postcard from Auntie Nancy, (7) ________ to Australia; the menu from a
take-away Chinese restaurant; an invitation to a wedding that we're going to
next Saturday; a letter from a friend we haven't seen for years. Our entire
world is there for everyone to read!

The
front door is seldom used in our house, only by strangers. All our friends use
the back door which meansthey come straight into the kitchen and join in
whatever is happening there. The kettle goes on immediately and then we all sit
round the table, drinking tea and putting the world to rights! Without doubt
some of the happiest times of my life have been spent in our kitchen.
