but I couldn’t because I had to go back to school.中主句的谓语是什么

but I couldn’t 的谓语已被省略。完整的句子可能是but I couldn’t go to the party because I had to go back to school.

这句话可以看成是一个复合句，but I couldn’t是主句，because I had to go back to school是从句。主句的谓语是couldn’t ，从句的谓语是had ，而to go是非谓语。

三楼有明显错误
从句的谓语是go，而had to是固定短语，
可译为：不得不。

省略句，谓语是couldn't + v.

couldn"t
