Question

The teachers that i have valued and enjoyed most of all, though, have been the teachers who taught me about love.
句中though 是副词“不过，然而”的意思吧。
后面的have been the teacher who，have been主语是？
觉得怪怪的：The teachers have been the teachers who...

Answer 1

though 是副词“不过，然而”的意思。你的理解是正确的。
have been主语是The teachers ，后面的（that i have valued and enjoyed most of all,）是一个定语从句。
主要是该句子用了两个定语从句来表达的。

Answer 2

have been主语是句首的The teachers

Answer 3

have been the teacher who，have been主语是The teachers that i have valued and enjoyed most of all，其中that i have valued and enjoyed most of all是定语从句修饰The teachers
