Dear Mum,

How are you in London? I'm fine in Wuhan.

These days, it is hot here. I really miss (想念) the cool summer in London.

Today is Saturday and I don't go to school. I want to tell you about my new friend Daning. He is my classmate and he helps me a lot at school. He is twelve years old. He likes playing basketball and he plays it very well. It's nice to be his friend.

Yours.

Eric
