2 Read and answer. Write in your notebook.
It was my 11th birthday on September, 29. My friends and I had a Treasure
Hunt in the park in front of my house. There were six of us and we were
pirates for the day. It was great fun! We went up and down the park to find
all our party food! The sandwiches were behind the tree and the drinks were
in a box opposite the table! And where was my birthday cake? It was on a
chair, under a big hat! All my friends found a present each, then we sat down
to eat. It was a great day!
