1. He was happy and left this morning.

2. He left this morning very happy. 

上面句子中1是并列谓语，2是双重谓语吗？两者有什么区别？

【答】是的，可以这样称谓。区别是：

1. He was happy and left this morning.   was happy 和left 是并列关系。

等于：He was happy and he left this morning.  

2. He left this morning very happy. very happy 和left 是修饰关系。

等于：He was very happy when left this morning.

I am ready to fight Zorro and（to） win!

这个句子是并列表语吗？

 【答】be ready to do sth. 属于“合成谓语”，所以to do sth. 是合成谓语的一部分，不能是并列表语。
