想问：
1—well—balanced curriculum：
2— can be a major contributing factor：就是不明白这种can+be+n的结构.怎么翻译这样的结构.是不是can后面不能直接n 想加n得跟个动词,这里由于没有动词,所以用be来代替.
contributing ：1.贡献的,起作用的 comprehensive：这里是综合的
1—physical education is vital element in a comprehensive，well—balanced curriculum ：
综合的 均衡的课程中，体育教育是一个重要的因素。
2—and can be a major contributing factor in the development of the traditional education：
翻译：在传统教育的发展中，（体育教育）是一种重要的起作用的因素。
can + be n./ do sth.就这两种形式，翻译成“是”即可
