有关started的属性与功能,你的理解是正确的.
started是个过去分词(非谓语动词的一种),不能单独作谓语.这个句子中它可以变为定语从句:
...which was started by the plane crash.
此时,started 与be 动词构成从句的谓语动词.
后置定语使用情况不多:
1、形容词修饰不定代词时,需要后置.
2、定语太长时,需要后置,相当于定语从句.
注意:The man dressed a red T-shirt is our teacher.有误.
应该是:The man dressed in a red T-shirt is our teacher.
相当于:The man who is dressed in a red T-shirt is our teacher.
