Gao Tianyu here. I'm just back from me three-month trip to the United States. Lots of people want to know about my trip,so I'm here to tell you all about it.I stayed in a place calles Kentucky,and want to school there. My school was called Jefferson High. Many things were different to China. Students usually take seven or eight subjects.There are five subjects that students must take.There are called "required" subjects,and they are English,math,science,social studies and P.E.
