hi! teachers here
which does sound more natural to native English speakers?
The sentences below are from my essay to be a good math teachers.
1.Good math teachers are those who inspire self-confidence for their students.
2. Good math teachers have to inspire self-confidence for their students.
Both are okay, though I would say in their students, not for their students.
The first is a description, the second is a requirement.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
