语法分析：if your monkey arrived in the box dead...call 911.

哈哈,这句是南方公园里的对白
如果送到你那里的盒子里的猴子死了,请拨911
monkey arrived
monkey in the box
dead monkey
组合起来就是monkey arrived in the box dead.
dead 就是表示状态——猴子死了
拆开看你就明白了
if you find him dead,call 911
A man is lying in the middle of a field,dead.
A man is lying dead in the middle of a field.

不是，是修饰monkey的
