[单项选择]Real policemen hardly recognize any resemblance between their lives and what they see on TV. These are similarities, of course, but the cops don’t think much of them.
The first difference is that a policeman’s real life revolves round the law. Most of his training is in criminal law, and what is more, he has to apply it on his feet, in the dark and rain, running down an alley after someone he wants to talk to.

A. so that he can catch criminals in the streets
