雅思英语语法问题, 详见下面的句子
The enter test can be used diagnostically as a means of prioritising the language areas to be cvered, either for the class ,or for individual students.

其中,为什么用to be coverd 来修饰the language areas, 这是什么语法现象?
另外,individual students 中,individual 不是个体嘛,那后面的student 为什么用复数?

Answer 1

to be covered是不定式作后置定语(post-modifier),意为要被涵盖的语言区域.
individual是形容词,意为单独的,个体的.individual students意思是学生各自.形容词的意思并不限制被修饰名词的单复数；单复数会受到限定词的限制,比如说each,every.这里的individual students=every student=an individual student (an也是限定词).
