Dear Jenny，
Here are some pictures of my vacation. In the first picture， I'm swimming in the sea. It's cool. In the second picture， I'm shopping with my friend. We want to buy some beautiful clothes. In the next one， I'm singing at a party. We are having a good time. Look at the last picture， I'm cooking at home. We usually enjoy it very much during the vacation.
Tina
