Point

Practice
․ We should carefully think about the reason for someone's behavior to avoid [coming / to come] to a hasty conclusion about it.

․ Industries are competitively changing their businesses into e-businesses, and thus the demand for the required workforce is expected [growing / to grow]

․ You'd better practice [to speak / speaking] English for thirty minutes a day.
