? Can you forgive me for two minutes and finish this problem before class is over? I believe this sentence is the most annoying sentence when I was a student. Usually, the time measurement of teachers is the same as ours, but once this sentence is said, the time measurement unit of teachers is different from ours. After this sentence, the teacher's unit of time measurement is two minutes equal to the unknown. Keep talking when you have time. Anyway, in the teacher's cognition, it is within two minutes, one after another, endless. But this sentence also contains the teacher's deep love for us. All the time the teacher said is knowledge to me. Teachers get nothing during these hours and have to give up their own time. Usually he has classes, and teachers are paid to attend classes. But? Delay? Our time is free, which is equivalent to a short free make-up class. ?
