Actually, I'm learning English speaking and I'm not good at it.
During learning English, I've got a question.
How do you feel those two sentences?
I knew people would be unhappy with the new tax policy
I knew people would be unhappy by the new tax policy
I've heard native speaker said 1.
but I guess, when it comes to non-native speaker, saying 1. is difficult.
is 2.sentence little bit strict feeling??
