The state has proposed new rules that would set minimum staffing levels for nurses, rules intended to ensure that at least one nurse is assigned for every four patients put through triage in a hospital emergency room.

劃綫的是主句主謂，土黃的是從句主謂（前定從，後賓從）
第二個rules是第一個rules的同位語
put through triage blah~是修飾patients的noun modifier，就是說patients are put through blah~

多谢啦。
发现同位语有很多问题，一直没太明白。

某gmat-expert寫的blog，這篇文章是專門關於同位語的~看看能不能幫到你哈XDD~
