I think it depends on the student and their age. Younger students should probably learn a lot of different subjects to see what they like. Later, when they're older, they can focus on just a few. Also, some jobs need you to know a lot about one thing, but others want you to have many different skills.
我認為這取決於學生及他們的年齡。年紀較小的學生應該學習很多不同的科目,以了解他們喜歡什麼。後來,當他們年紀較大時,可以專注於少數幾個科目。此外,有些工作需要你對某一領域有深入了解,但其他工作則希望你擁有多種不同的技能。
