山间徒步育人：传承多年的特色传统（补全句子）
A New Jersey school has a special tradition of over 50 years. Every new student must finish a five-day mountain hike (远足) before moving to the next grade. Many students have never hiked or camped outdoors before.
Before the trip, students train hard and learn different roles in small teams. No one can finish the hard journey alone. They need to help each other with little help from adults (成年人).
Students feel tired after the hike, but they grow greatly. They learn to overcome difficulties and finish hard things together.
