they were happy to be with each other on the ship called the titanic.

问题描述:

they were happy to be with each other on the ship called the titanic.
为什么还用called.不是已经有were作谓语了吗?

they were happy to be with each other on the ship (which was)called the titanic.
()内是省略部分,这其实是一个定语从句,说明船的名字是泰坦尼克.
定语从句中指示代词和BE可以一同省略
