In the United States, teaching is very important. If teachers do not teach well, students complain. If many students do not understand, people think that the teacher does not do a good job.

Cocaine possession, with intent to distribute, it said. Byrd tried to tell them that they had the wrong man, that it was a case of mistaken identity. But they wouldn’t listen. Instead they put him in handcuffs (手铐) and drove him away.
It was nothing new for Byrd, who has spent much of the past five years trying—unsuccessfully—to talk skeptical police officers out of arresting him. But this time, it was worse. Two days later, he was still in jail.
