A Letter from a Senior High Student
Dear Li Kang,
How's it going?I thought I'd write to tell you about the American school system.Secondary school in the US usually covers seven years,grades six to twelve.Ninth to twelfth grades are high school.At the end of twelfth grade,American students receive the high school diploma.Students need a high school diploma if they want to go to college.
The school year is divided into two semesters,the first of which is September through December,and the second January through May.We have a LONG summer vacation!We start school at 7:50 am and we finish at 3 pm.
I take part in all kinds of after—school activities—I play football,basketball,volleyball,table tennis and I go to theater club.
Will you tell me something about your summer vacation and the Chinese school system in your next letter?
Rob Marshall
