帮我分析下句子成分,还有when这里引导的是状语从句吗?
when 引导的如果是状语从句,那么属于哪种呢?感觉不会是时间状语吧?

Pumas never attack a human being except when they are cornered
美洲狮从来不会主动攻击人类除非他们被逼无奈。

when是引导状语从句
a human being指人
主句就是：Pumas never attack a human being.

Puma(主语) never(副词做状语) attack(谓语) a human being (宾语) except(介词) when they are cornered(时间状语从句，与前面的never平级)

美洲狮从来不会主动攻击人类除非他们被逼无奈。

美洲狮只有在绝境时才会攻击人类。。

后面的问题不清楚。。。。

半年多没学语法了。。
