由于学生背负着沉重的家庭作业的担子，一些教育家呼吁公众多关注他们的身体健康。

Answer 1

30.(With) The students burdened with / As the students are burdened with考查with复合结构或独立主格结构的用法。be burdened with负担。逗号前需要的是原因状语。而原因状语可由状语从句、"with+ n. / pron.+宾补"结构或独立主格结构充当。with复合结构中的宾补可以是v.-ing / v.-ed/不定式/(being + )形容词/副词/名词/介词短语等。因"学生"是"背负"的承受者，所以在(with + )独立主格结构中，burden 用过去分词形式。
