这个句子的正确成分如下:
They作主语,are是一个连系动词,是谓语,to pay a visit to their teacher tomorrow morning是整个不定式作表语,to their teacher 是介词短语,所以这个TO是一个介词.

to their teacher 在句中做什么成分？

tomorrow morning 也是状语，一个句子中可以存在两个或两个以上的状语吗？

They 主语
are to pay 谓语，整个BE to do 结构是谓语，这里的to是不定式
a visit宾语，是不定式的宾语，不定式是这个句子的谓语，也就是整个句子的宾语
to 介词表示对象这里，
their teacher做介词 to的宾语
tomorrow morning，时间状语
