读咸阳—潼关河段纵坡剖面示意图，完成下列问题。（14分） （1）泾河和渭河的交

Dear Mary
I saw your name in the newspaper, you asked for penfriends in China. I would like to be your penfriend.
I am a thirteen- year- old boy. I live in Nanjing. I am a student at No.1 Secondary School. We study Chinese, English, Maths, Science, Art, PE and some other subjects. My favorite subjects are Maths and PE. I like playing the guitar, collecting stamps and taking photos. I like summer best because my favourite sport is swimming.
My family is not big. My grandfather, my father, my mother, and I live a happy life here. My father is an engineer, my mother is a doctor. My grandfather was a policeman and now he is retired（退休）. We live in an old house. Near our house, there is a beautiful park. Our family often take a walk in the park after supper.
I would like to know something about you and the UK. Please write to me soon. My e-mail address is yuren@163.com.My fax and telephone number is 86-25-82011853.
