high -school education should be extended to four years

Question

nowadays, some educators suggest  extending high school to four year so that student can achieve all this is ecpected of them. Others are against the proposal because they think student would lose interest in school. in my opinion, i think three-year is enough for student

firstly, i think the three-year high school is enough to build the basic for academic or practical knowledge that can be imparted by schooling. Three-years is not too short for student to get knowledge and build griendship. Someone usually said that the time high shcool was too quick for them to adapt. i think this is not true.in the preiod of three years, they could prepare enght for higher education

secondly, not all one can pass a grade in a year so four-year high school would totally discourage them . teenagers are too enthusiastic so they do not have enough  patience for spend our time in school. It is uut of question that in five years student can understand the lessons more deeply but it would lead to the boring of them or student could lose interest in school and attendance would drop in the end.

all in all, i think 3 years is suitable for student to get enough knowledge and skills. We should not extend the preiod of high school
